Flying with reduced visual cues

SafetyWatch_icon_1.png

Safety concern

The ATSB continues to investigate accidents—many fatal—that involve pilots flying with reduced visual references.

Under visual flight rules (VFR), it is crucial that pilots have sufficient visual reference to see and avoid obstacles. Visual cues are also required to maintain orientation so VFR pilots know which way is up and can maintain control of their aircraft. Visual reference can be reduced by cloud, darkness, or atmospheric conditions such as rain, fog, smoke or haze. Two main risks are associated with flying in limited visibility:

  • loss of orientation, leading to loss of control of an aircraft and an uncontrolled flight into terrain
  • insufficient visibility to enable a pilot to see and avoid obstacles while remaining under control, known as a controlled flight into terrain.

The same hazards can also apply during night flight because there are often less visual cues at night, even though the visibility may be good.

ATSB Privacy Policy

The Australian Transport Safety Bureau (ATSB) is committed in respecting your right to privacy and protecting your personal information in accordance with the Privacy Act 1988(Opens in a new tab/window) (Privacy Act) and our policies and procedures. We also comply with the requirements of the Australian Government Agencies Privacy Code 2017(Opens in a new tab/window) (Privacy Code).

Accordingly, the ATSB has appointed a Privacy Officer and a Privacy Champion to carry out their respective functions under the Privacy Code. The ATSB publishes this policy to demonstrate its commitment to privacy rights, including by complying with the Privacy Act and the Australian Privacy Principles (APPs).

In this policy, personal information has the same meaning as defined in section 6 of the Privacy Act:

personal information means information or an opinion about an identified individual, or an individual who is reasonably identifiable:

(a)   whether the information or opinion is true or not; and

(b)   whether the information or opinion is recorded in a material form or not.

Some examples of personal information include names, addresses, banking details, licence and registration numbers, or photographs. It may also include indirectly identifying information, such as the description of an event, where the identities of any persons involved in the event are apparent even though no names are used. Whether or not the description of the event contains personal information may depend on the context and who is reading the information.

Collection of personal information

Solicited personal information

The ATSB generally collects personal information for the purposes of fulfilling the various functions or activities of the ATSB. This includes the ATSB’s primary function of conducting independent aviation, maritime and rail safety investigations under the TSI Act as well as receiving notifications from industry of the occurrence of accidents and incidents.

The TSI Act does contain some coercive information gathering powers that may be used to acquire personal information. However, normally the ATSB seeks to obtain personal information with the consent of the individual concerned.

In some circumstances the ATSB may collect personal information from a third party. This includes where information is provided via the mandatory scheme for the notification of accidents and incidents. The ATSB distributes material that seeks to make participants aware in the aviation, maritime and rail transport industries of the likelihood of their details being passed on to the ATSB if they are involved in an accident or incident. Where practicable, if the ATSB receives personal information via a third party, the ATSB will seek to notify the individual concerned of the circumstances of the collection.

The types of personal information that we generally collect and hold will include:

  • personal contact details
  • personnel/employee records including educational or professional qualifications, job application information and pay, superannuation and tax information including tax file numbers (TFNs)
  • credit card application records
  • information in delegations
  • staff conflict of interest declarations
  • information in ministerial correspondence
  • Freedom of Information applications
  • details of persons who attended ATSB training courses
  • mailing and subscription lists
  • survey responses where the individual chooses to disclose personal information
  • contract, tender and submission documents
  • financial payment records
  • records for legal proceedings
  • complaint and feedback information
  • investigation records including witness statements, flight crew licences, training and qualification details, investigator’s notes and interview reports
  • records of accidents and incidents notifications.

Sensitive information

Personal information that is ‘sensitive information’ is defined by section 6 of the Privacy Act to include information or an opinion about an individual’s racial or ethnic origin, political opinions, membership of a political association, religious beliefs or affiliations, philosophical beliefs, membership of a professional or trade association, membership of a trade union, sexual orientation or practices, criminal record, health or genetic information, biometric information and templates.

Sensitive information is afforded a higher level of protection under the Privacy Act, including limited circumstances in which it can be collected. The ATSB does not normally have a need to collect the majority of the sensitive information referred to in the definition. The exception is for the aviation, maritime and rail accident investigations it conducts under the TSI Act. For the purpose of fulfilling its statutory functions, the ATSB may collect and hold sensitive personal information, including:

  • medical reports;
  • physical and psychological profiles of persons involved in the occurrence;
  • results of breath tests or blood alcohol levels;
  • membership of a professional or trade association or trade union; and
  • criminal records.

Where applicable, after obtaining the information holder’s consent the ATSB will typically obtain the sensitive information after issuing its holder a direction under section 32(1) of the TSI Act. This allows the information to be designated as ‘restricted information’ for the purposes of the TSI Act and afforded additional statutory protection.

Unsolicited personal information

Where the ATSB received unsolicited personal information, the ATSB must determine within a reasonable period if the information could have been collected in accordance with its functions and activities.

If the information could not have been collected in accordance with the ATSB’s functions and activities, and is not contained in a Commonwealth record, the ATSB must ensure the information is lawfully destroyed or de-identified.

Anonymity

The identity of an individual is typically relevant and necessary in order to achieve the ATSB’s purpose for collecting, using, holding or disclosing personal information. It is therefore unlikely to be practicable for the ATSB to deal with individuals who have not identified themselves or who have used a pseudonym. If an individual is concerned about not being able to deal with the ATSB anonymously, they may contact the Privacy Officer and discuss the circumstances.

How the ATSB stores personal information

The ATSB stores all personal information securely and restricts access to a limited number of staff that need access in order to perform their duties or assist individuals. Most personal information held by the ATSB is stored electronically such as on databases, shared drives or in emails, or on hard copy files.

The ATSB takes all reasonable steps to ensure that personal information is protected from misuse, loss and interference.

When information is no longer required it is securely destroyed in accordance with the
Archives Act 1983(Opens in a new tab/window) (Archives Act) and relevant disposal authorities or forwarded to the National Archives of Australia(Opens in a new tab/window) (NAA).

Use and disclosure of personal information

The ATSB will only use and/or disclose personal information for the purposes for which it was collected (the primary purpose), unless an individual has consented to another use.

There are certain limited circumstances in which the ATSB may use or disclose information for a different purpose (a secondary purpose) without consent, such as where the secondary purpose is:

  • directly related to the primary purpose for which the information was collected;
  • required or authorised under an Australian law or has been ordered by a court or tribunal;
  • necessary to lessen or prevent a serious threat to the life, health or safety of any individual, or public health or safety;
  • a permitted general situation or health situation, as defined by the Privacy Act; or
  • an enforcement related activity and the use or disclosure of the information is reasonably necessary.

In relation to information collected from occurrence reporting that you submit to the ATSB, in accordance with the ATSB’s function of improving transport safety, de-identified, anonymised or aggregated information may be shared by the ATSB with other Commonwealth agencies for the purposes of safety research and education. More information on the ATSB’s collection, use and disclosure of transport safety information can be found in the ATSB’s safety information policy statement.

The ATSB is also required to comply with the Freedom of Information Act 1982(Opens in a new tab/window) (FOI Act) under which any person has a legal right to request access to documents held by Commonwealth agencies. The information you provide in occurrence reporting may be the subject of an FOI request. In respect of any personal information that might be contained in a document subject to an FOI request, the ATSB will have regard to the personal privacy provisions and/or consultation mechanisms under the FOI Act.

If the ATSB uses or discloses personal information for a purpose other than what it was originally collected for, the ATSB will keep a written notice of that use or disclosure as required by the APPs.

Disclosure of personal information overseas

The ATSB does not routinely disclose personal information to overseas recipients. However, there may be occasions related to the ATSB’s safety investigation function where this is necessary. In some circumstances there may be parties overseas who are connected with the occurrence of the accident in which case there may need to be a cross-border flow of information. In these cases the ATSB complies with APP 8, including seeking to provide assurances that the information will be protected and used in accordance with the APPs.

Additionally, the ATSB may use third party services (such as Google analytics and YouTube) embedded on our website or linked through our website to manage, provide and maintain user tracking and analytics, including for the purposes of industry engagement, policy consultations and collecting feedback. Google products may use cookies and other information to track and see how users interact with ATSB content. The information generated by the cookie about your use of our website, including your IP address, will be transmitted to and stored by Google on servers in the United States.

Google use this information to evaluate how you use website content, including website activity and internet usage. Google may transfer this information to third parties where required by law, or where third parties process the information on Google's behalf. See Google’s privacy policy(Opens in a new tab/window) for more information.

Occasionally, an individual may be invited by the ATSB to participate in a survey using Survey Monkey (a third party software supplier) for the purposes of receiving industry feedback about a range of matters relevant to the ATSB’s functions. The ATSB will only use the information provided for the purposes of collating and analysing feedback provided, and in accordance with the ATSB’s privacy policy. Participating in a survey is voluntary. An individual is not obliged to provide personal information as part of a survey, but this may be desirable for transparency and further communications between the ATSB and the individual.

Survey Monkey is based in the United States and in the European Union (EU) and the information generated by cookies (including an individual’s IP address) will be transmitted to and stored by Survey Monkey on servers located outside Australia. The ATSB needs to inform you that, should you wish to respond to a survey, you:

  • consent to your personal information being collected, used, disclosed and stored as set out in Survey Monkey’s privacy policy(Opens in a new tab/window) and agree to abide by Survey Monkey’s terms of use(Opens in a new tab/window);
  • understand and acknowledge that this service utilises a third party software platform, which is located in the USA and the EU, and relevant legislation of those countries will apply; and
  • you understand and acknowledge that Survey Monkey is not subject to the Commonwealth Privacy Act 1988 and you will not be able to seek redress under Australian legislation but will need to seek redress under the laws of the USA and the EU for any privacy breaches.

Response to a voluntary survey may also be undertaken by printing out a copy of the online survey form and emailing the completed document to the relevant ATSB email address.

The ATSB does not use third party suppliers for mandatory occurrence reporting and the database associated with occurrence notifications is stored in Australia.

Access to personal information

Under APP 12, individuals have the right to access their personal information held by the ATSB. There is no cost associated with making a request. The ATSB will process the request and provide access to the information within 30 days after the request is made. If the ATSB decides not to grant access to the information, a written statement of reasons will be provided.

This mechanism operates alongside the Freedom of Information Act 1982(Opens in a new tab/window) (FOI Act) under which an individual may request access to personal information held by the ATSB.

Information on how to apply for access to your personal information under the FOI Act, please go to Freedom of Information on the ATSB website.

To assist ATSB in locating any information held more quickly, an individual is encouraged to provide as much information as possible, such as, dealings they have had with the ATSB.

Correction of personal information

Individuals have the right under APP 13 to request corrections to any of their personal information held by the ATSB that they consider the information is inaccurate, out-of-date, incomplete, irrelevant or misleading. This APP also operates alongside the FOI Act under which an individual may make a request to have personal information amended or annotated.

If an individual considers information held by the ATSB requires correcting, a written request should be sent to the ATSB’s Privacy Officer outlining what aspect of the information needs correction.

There is no charge associated with making a request or for associating the statement with the personal information and notification of the outcome will be provided within 30 days. If the ATSB refuses to correct the information, a written explanation will be provided. However, if the individual requests the ATSB to associate with the information a statement that the information is inaccurate, out of date, incomplete, irrelevant or misleading, the ATSB will take reasonable steps in the circumstances to associate the statement which will make it apparent to users of the information.

If the ATSB has disclosed the information previously to a third party, an individual may request that the third party also be notified of any correction made. If it is reasonable and practical to do so the ATSB will notify the third party of the corrections.

For security reasons, and to protect personal information, applicants may be asked to provide proof of identification.

How to request access or correction

To make a request for access to or correction of personal information, a written request should be sent to the ATSB’s Privacy Officer on the contact details provided at the end of this policy. 

Tax File Numbers (TFNs)

The ATSB only collects TFN information where required for human resource purposes. The ATSB adheres to the Privacy (Tax File Number) Rule 2015 for the collection, storage, use, disclosure, security and disposal of TFN information. 

Privacy impact assessment register

The ATSB conducts a Privacy Impact Assessment (PIA) for all high privacy risk projects. A project may be a high privacy risk if it has a significant impact on the privacy of individuals. The ATSB maintains and publishes a PIA Register on its website.

Privacy complaints

Public Interest Disclosure Scheme

PID logo

The Public Interest Disclosure (PID) scheme builds on existing policies and procedures to protect public officials (including current and former APS employees, people exercising powers under a Commonwealth law and contracted service providers) who speak up and ‘blow the whistle’ on suspected wrongdoing by public officials.

The PID scheme provides a transparent process for agencies and government departments to investigate complaints.

The Public Interest Disclosure Act 2013(Opens in a new tab/window) (PID Act) underpins the operation of the scheme. The PID Act aims to promote the integrity and accountability of the Commonwealth public sector by:

  • encouraging and facilitating the making of disclosures of wrongdoing by public officials
  • ensuring that public officials who make protected disclosures are supported and protected from adverse consequences relating to the making of a disclosure
  • ensuring that disclosures are properly investigated and dealt with.

The PID Act does not replace existing processes for dealing with workplace grievances and misconduct, such as bullying and harassment, rather it supplements them.

The ATSB encourages people to come forward if they are aware of wrongdoing within the organisation. People who come forward and report wrongdoing are helping to maintain and promote integrity, accountability and good management within the ATSB.

The ATSB will act on disclosures as appropriate and protect disclosers from any reprisals or threats of reprisals resulting from the making of a disclosure. The ATSB is committed to effectively dealing with and investigating any disclosure of wrongdoing and taking appropriate action if an investigation finds some form of wrongdoing.

The ATSB’s procedures, 

 describe the steps you need to take to make a report. They also set out the actions the ATSB will take when receiving, dealing with and investigating public interest disclosures involving the ATSB.

A public interest disclosure can be made to the ATSB in person, by telephone or in writing, including by email.

Written reports using the 

 are encouraged as this can help to avoid any confusion or misinterpretation. The completed form can be delivered personally, mailed or emailed to the ATSB.

A public interest disclosure can be reported to any of the following authorised officers in the ATSB at PID@atsb.gov.au:

  • Peta Nisbet
  • Gerard Frawley

For more information about the making a public interest disclosure involving the ATSB, please contact Head of Legal Services by phone on 1800 020 616 or email at legal.services@atsb.gov.au.

More details about the Commonwealth Public Interest Disclosure scheme are available on the Commonwealth Ombudsman’s website(Opens in a new tab/window).

Occurrence category taxonomy and terminology

ATSB occurrence category taxonomy 

The ATSB uses an occurrence category taxonomy to efficiently and consistently categorise and code transport safety occurrences. These occurrence categories can be used to search through occurrences in the ATSB’s National Aviation Occurrence Database

A guiding principle behind the ATSB’s occurrence category taxonomy is that a relatively simple coding scheme greatly increases the quality of the data that is recorded in the occurrence database. The taxonomy follows a data-driven approach in that a particular occurrence category is only included in the taxonomy if either; 

  • it is an occurrence category commonly reported to the ATSB 
  • it is an uncommon but important occurrence category 

The ATSB Occurrence Category taxonomy is a three-level hierarchy. In general, the structure of the hierarchy follows the ICAO ADREP 2000 model, and is divided into the following Level 1 Occurrence Type groupings; 

  • Operational – occurrences that relate specifically to aircraft operations that involve a human element 
  • Technical – occurrences that relate specifically to a failed aircraft component or system 
  • Airspace – occurrences that relate specifically to controlled and uncontrolled airspace issues 
  • Infrastructure – occurrences that relate specifically to the failure or anomalies with aerodrome and ATC facilities that directly affect an aircraft operation 
  • Environment – occurrences specifically related to external influences that have a direct impact on aircraft operations 
  • Consequential Events – occurrences that relate specifically to an operational necessity as the result of one of the other Level 1 groupings. 

Each of the Level 1 Occurrence Category groupings is sub-divided into a number of related Level 2 groupings. In turn, Level 2 Occurrence Category groupings are further sub-divided into Level 3 groupings.  

AIMS occurrence taxonomy 2023

The hierarchical nature of the Taxonomy is of fundamental importance. It allows Level 3 data to be logically aggregated into Level 2 groupings, and then subsequently into Level 1 groupings. This is essential for higher-level data analysis. 

In some cases an occurrence category may fall across two or more Level 1 groupings. Rather than create a specific coding for each Level 1 grouping, the hierarchy has been designed to capture it under the more common of the occurrence types. 

Occurrence classifications

Prior to 31 December 2022

Accident: an occurrence involving an aircraft where:

  • a person dies or suffers serious injury
  • the aircraft is destroyed, or is seriously damaged
  • any property is destroyed or seriously damaged.

Serious incident: an incident involving circumstances indicating that an accident nearly occurred (ICAO Annex 13).

Incident: an occurrence, other than an accident, associated with the operation of an aircraft which affects or could affect the safety of operation (ICAO Annex 13).

From 1 January 2023

Aircraft accident

A person suffers a fatal aircraft-related injury in relation to the operation of the aircraft; or

A person suffers a serious aircraft-related injury in relation to the operation of the aircraft; or

The aircraft sustains damage or structural failure, or there are reasonable grounds for believing that the aircraft has sustained damage or structural failure, which:

  1. Adversely affects the structural strength, performance or flight characteristics of the aircraft; and
  2. would normally require major repair or replacement of the affected component.
  3. Except for any of the following:
    • Engine failure;
    • engine damage limited to a single engine (including damage to its cowlings or accessories);
    • damage to propellers, wing tips, antennas, probes, vanes, tyres, brakes, wheels, fairings, panels, landing gear doors or windscreens;
    • damage such as small dents or puncture holes to the aircraft skin;
    • minor damage to main rotor blades, tail rotor blades or landing gear;
    • minor damage resulting from hail or bird strike (including holes in the radome); or
    • the aircraft is missing; or
    • the aircraft is completely inaccessible

Serious aircraft incident

A serious aircraft incident is an incident involving:

  • Circumstances indicating that there was a high probability of an aircraft accident (that is, a high probability of a fatal or serious aircraft-related injury and/or the aircraft sustaining damage or structural failure); or
  • an incident in the following table of incidents that have the potential to be classified as a serious incident.

Aircraft incidents

Any event that is associated with the operation of an aircraft and affects, or could affect, the safety of the operation of the aircraft.

The degree to which an occurrence “affects or could affect” the safety of the operation of the aircraft should be understood to mean occurrences that, if not corrected, could endanger the aircraft or its occupants. To be clear, a responsible person is required to report an aircraft incident whether or not it was actually corrected or able to be corrected.

National Aviation Occurrence Database

The National Aviation Occurrence Database allows you to search for accidents and incidents that have been reported to the ATSB since 1 July 2003. You can search the database using a time period, location, type of occurrence (i.e. what happened), and type of aircraft.

We regularly add new reported occurrences to ensure the database is up to date. However, depending on workload and volume of reports it may take some weeks to verify and include new occurrences.

How ATSB data is collected?

ATSB data is collected through the mandatory occurrence reporting requirements of the Transport Safety Investigation Act 2003 and associated Regulations from the aviation industry. It is provided publicly as a result of the cooperative efforts between the ATSB and the aviation industry as a whole. 

Can I download your whole database?

No. The ATSB limits the full export of the National Aviation Occurrence Database, which has been made available for general statistical purposes only. This is due in part to the need for the ATSB to preserve confidentiality, continuously update and improve data on receipt of additional information and on-going data cleaning efforts. The National Aviation Occurrence Database is the only authoritative and controlled dataset that is updated regularly. Some data may be missing, incomplete or yet to be reported and/or entered. The ATSB does not endorse, and disclaims any responsibility for, use of the data beyond general statistical purposes. The ATSB also does not endorse the use of its aviation occurrence data for any commercial purposes.

Taxonomy and terminology

The ATSB uses an occurrence category taxonomy to efficiently and consistently categorise and code transport safety occurrences. Read more here.

Limitations of the data

The data quality and consistency is largely dependent on the details reported to the ATSB. The information in the majority of non-investigated occurrence reports is not subject to verification.
 
This data is subject to change. The ATSB may need to update and improve the data as it receives additional information and validates the data already received.

ATSB data includes information obtained from all reports that meet the reporting requirements of the Transport Safety Investigation Regulations 2021. Not all notifications reported to the ATSB are classified as incidents, serious incidents or accidents. Those that are deemed to not be a transport safety matter are classified as ‘events’. Events are not included in this database.

Notifications that do not relate to aircraft safety are coded as events (such as cabin injuries not related to the operation of the aircraft, and airport infrastructure, navigation aids and air traffic control facilities failures that do not directly involve an aircraft). In addition, notifications of the following types of notifications when they occur without any other occurrence type event are generally coded as events:

  • consequential events (diversion/return, fuel dump/burn off, missed approach/go-around)
  • operational non-compliance with air traffic control verbal or published instruction
  • airspace infringement
  • breakdown of co-ordination between air navigation service providers.

Prior to October 2014, the ATSB online aviation occurrence database did include operational non-compliance, airspace infringement and breakdown of co-ordination notifications as incidents.

Disclaimer on data use

The ATSB collects aviation safety data and investigates air safety occurrences for the sole purpose of enhancing aviation safety.  Consequently, the ATSB material is confined to matters of safety significance and may be misleading if used for any other purpose.

The ATSB aims to publish occurrence data as soon as reasonably practicable after receiving reports from industry. However, depending on workload and the volume of reports received, it may take some weeks to input the data into the database from when we received the report. If you are seeking data or information on a specific recent occurrence that does not appear in search results, you should contact the ATSB via email: atsbinfo@atsb.gov.au

When using this data, it is important to remember that occurrence data is provided to the ATSB by responsible persons as defined in the Transport Safety Investigation Regulations 2021.

The ATSB accepts no liability for any loss or damage suffered by any person or organisation resulting from the use of this data. The ATSB does not warrant the completeness, accuracy or suitability of the data and the database for your intended purpose.

REPCON – Rail Voluntary and Confidential Reporting Scheme

What is REPCON?

REPCON is a voluntary and confidential reporting scheme. REPCON allows any person who has a rail safety concern to report it to the ATSB confidentially. Protection of the reporter’s identity and any individual referred to in the report is a primary element of the scheme.

Who may make a REPCON report?

Any person may report a reportable safety concern. This would include:

(a)  Any person involved in the Rail Industry. An example would be an employee or contractor of a rail transport operator who may have reported a matter under the operator’s SMS but does not believe it will be properly dealt with. It may also be where that person has not reported under the SMS because they believe they will suffer retribution; or

(b)  a member of the travelling public.

What may be reported with REPCON?

Each of the following concerns (reportable safety concerns) in relation to the safety of railway operations to which the Regulations apply are examples of what may be reported under REPCON. The list is not exhaustive:

(a) an incident or circumstance that affects or might affect the safety of railway operations;

(b) a procedure, practice or condition that a reasonable person would consider endangers, or, if not corrected, would endanger, the safety of railway operations,

for example:

(i) poor training or behaviour that is not consistent with the rail transport operator’s safety  management system; or
(ii) insufficient qualifications or experience of employees of a rail transport operator; or
(iii) scheduling or rostering that contributes to an unacceptably high risk of fatigue of employees of a rail transport operator; or
(iv) a rail transport operator bypassing safety procedures because or operational or commercial pressures; or
(v) inadequate railway station or terminal facilities for safe railway operations; or
(vi) unsafe passenger, or freight management; or
(vii) inadequate operational information that could lead to an unsafe situation;

 (c) any other matter that endangers, or could endanger, the safety of railway operations not reportable under a mandatory reporting scheme.

If you are in any doubt whether the matter you wish to report is covered by the REPCON scheme or a mandatory reporting scheme please call us.

What is not a reportable safety concern?

To avoid doubt, the following matters are not reportable safety concerns and are not guaranteed confidentiality

  • matters relating to a serious and imminent threat to a person’s health or life
  • industrial relations matters
  • conduct that constitutes a criminal offence
  • terrorist acts. If you wish to provide information about terrorist activity you should call the National Security Hotline on 1800 123 400.

Matters which must be reported under a mandatory reporting scheme should not be reported under REPCON. This will not discharge your reporting obligations under a mandatory reporting scheme.

If you believe it would be necessary to act on information about an individual referred to in your report then you should report this directly to the Office of the National Rail Safety Regulator(Opens in a new tab/window), the appropriate regulator in your state or the rail operator.

What is confidential?

Personal information about the reporter and any person referred to in the report. If you believe it would be necessary to act on information about an individual referred to in your report then you should report this directly to the Office of the National Rail Safety Regulator on 1300 550 865.

Is an anonymous report via REPCON acceptable?

REPCON does not accept anonymous reports. REPCON staff cannot contact an anonymous reporter to verify the report or to seek additional information. Further, REPCON staff must be satisfied that the reporter's motivation for reporting is rail safety promotion, and that the reporter is not attempting to damage a rival or pursue an industrial agenda.

How are REPCON reports processed?

REPCON staff will assess each report for clarity, completeness and significance for rail safety and to ensure it meets the requirements of a Reportable Safety Concern (RSC) for rail.

The report will be de-identified to remove all personal details of the reporter and any individual named in the report. This will be passed to the reporter who must authorise the content before the REPCON can proceed further.

The de-identified text is then forwarded to the relevant organisation that is best placed to address the RSC. The organisation’s response will then be forwarded to the Regulator for further action as deemed necessary.

REPCON may use the de-identified version of the report to issue an information-brief or alert bulletin to a person or organisation, including the Regulator, which is in a position to take safety action in response to the safety concern.

If the reporter has previously reported the concern to any organisations involved or to the regulator, the protection of the reporter’s identity may be jeopardised. As such, the concern may not be able to be progressed through the REPCON system. REPCON staff will assess each report and discuss options on how to best progress the safety concern.

What are the possible outcomes from a REPCON report?

The desired outcomes are any actions taken to improve rail safety in response to the identified concern. This can include variations to standards, orders, practices, procedures or an education campaign.

Why is REPCON important?

REPCON reports can serve as a powerful reminder that, despite the best of intentions, well-trained and well-meaning people are still capable of making mistakes. The de-identified stories arising from these reports may serve to reinforce the message that we must remain vigilant to ensure the ongoing safety of ourselves and others.

How can I make a REPCON report

REPCON reports can be submitted by: Online REPCON form

Mail: GPO Box 321
Canberra ACT 2601

Telephone: 1800 020 505
Email: repcon@atsb.gov.au

If you require assistance, advice or further information, please call REPCON on 1800 020 505.

Submission of information known by the reporter to be false or misleading is a serious offence under section 137.1 of the Criminal Code. Aiding, abetting, counseling, procuring or urging the submission of false or misleading information is also a serious offence.
