1.1. About the ATSB
1.1.1. The Australian Transport Safety Bureau (ATSB) is an independent Commonwealth government statutory agency. The ATSB is governed by a Commission and is entirely separate from transport regulators, policy makers and service providers.
1.1.2. The ATSB's function is to improve safety and public confidence in the aviation, marine and rail modes of transport through excellence in:
a. independent investigation of transport accidents and other safety occurrences;
b. safety data recording, analysis and research; and
c. influencing safety action, including through public communications, education and safety recommendations.
1.1.3. The ATSB is established by the Transport Safety Investigation Act 2003 (TSI Act) and conducts its investigations in accordance with the provisions of the Act. The fundamental objective of transport safety investigations is the prevention of accidents and incidents. Under the TSI Act, it is not a function of the ATSB to apportion blame or provide a means for determining liability. The ATSB does not investigate for the purpose of taking administrative, regulatory or criminal action.
1.1.4. The ATSB publishes all transport safety investigations, including identified safety issues and related safety actions, on the ATSB website atsb.gov.au.

2. Reporting of accidents and incidents
2.1. Introduction
2.1.1. The TSI Act specifies that certain accidents and incidents, known as reportable matters, must be reported to the ATSB by responsible persons. Depending on the severity of the accident or incident and the type of operation, reportable matters are defined in the Transport Safety Investigation Regulations 2021 (TSI Regulations) as either immediately reportable matters or routine reportable matters.
2.1.2. The ATSB is the repository for Australia’s official aviation safety occurrence database. While the ATSB does not investigate all accidents and incidents, it still needs to be notified of safety occurrences so that the information can be used for safety research and analysis. The ATSB publishes a number of statistical and research reports based on reported occurrences.
2.1.3. The ATSB publishes a searchable database of de-identified aviation accidents and incidents since July 2003. The database can be used for research and analysis, and is available at atsb.gov.au/avdata
2.2. Aircraft that must report reportable matters
2.2.1. All Australian aircraft operating inside and outside of Australia, including:
a. Australian-registered (VH) aircraft on the Civil Aviation Safety Authority (CASA) civil aircraft register
b. aircraft listed with sport aviation bodies
c. type 1 and type 2 remotely piloted aircraft (RPA) (type certified or an RPA greater than 250 g that is not an excluded RPA as defined by the Civil Aviation Safety Regulations 1998 (CASR) Part 101)
2.2.2. All foreign civilian-registered aircraft operating inside Australia.
2.2.3. The following aircraft are excluded from reporting:
a. Australian Defence aircraft – being aircraft used by the Australian Defence Force (other than aircraft registered on CASA’s civil aircraft register)
b. exempt foreign aircraft – being aircraft used by the military, customs or police services of a foreign country
c. an RPA that is not type 1 RPA or type 2 RPA (this means an excluded RPA as defined by CASR Part 101, or micro RPA below 250 g)
d. model aircraft
e. small (uncrewed) balloons and light (uncrewed) balloons
f. tethered balloons with no persons on board
g. kites
h. rockets (this is not considered an aircraft).
2.3. Responsible persons for reporting safety matters to the ATSB
2.3.1. Reportable matters known by responsible persons must be reported to the ATSB by that person unless that person believes, on reasonable grounds, that one or more other responsible persons:
a. have already reported the matter, or
b. will as soon as is reasonably practicable report the matter.
2.3.2. However, the ATSB still encourages all responsible persons with information about a reportable matter to report that information to the ATSB.
2.3.3. The following are responsible persons:
a. a crew member of the aircraft concerned
b. the owner or operator of the aircraft
c. a person performing an air traffic control service in relation to the aircraft
d. a person performing a dedicated aerodrome rescue or firefighting service in relation to the aircraft

2.4. Reporting of accidents and incidents
2.4.1. Immediately reportable matters must be reported by telephone to the ATSB on 1800 011 034(toll-free) as soon as is reasonably practical. If telephoning from outside Australia, please use (+61) 2 6230 4470.
2.4.2. Immediately reportable matters also require a more detailed written report to be submitted within 72 hours. Written reports can be submitted via the ATSB’s online reporting system atsb.gov.au/mandatory/, or via a data transfer from your company’s safety management system database.
2.4.3. Routine reportable matters only require a written report to be submitted within 72 hours. Written reports can be submitted via the ATSB’s online reporting system atsb.gov.au/mandatory/, or via a data transfer from your company’s safety management system database.
3. Reportable matters
3.1. Introduction
3.1.1. Reportable matters are defined in the TSI Regulations via a combination of the type of safety occurrences (see 3.1.2) and the type of operation (see 3.1.3). The combination determines whether a safety occurrence is an immediately reportable matter, routine reportable matter, or not reportable.
3.1.2. The TSI Regulations refer to the following types of safety occurrences:
j. an aircraft accident
k. a reportable serious aircraft incident
l. a loss of a separation standard between aircraft
m. a declaration of an emergency in relation to an aircraft
n. a serious property damage incident (external)
o. an aircraft incident
p. an aircraft incident (external).
3.1.3. The TSI Regulations refer to four categories of aircraft operations, each with different reporting obligations:
a. Category A (passenger transport) aircraft operation
b. Category B (commercial non-passenger) aircraft operation
c. Category C (non-commercial) aircraft operation
d. Category D (type 2 RPA and certain uncrewed balloons) aircraft operation.
3.1.4. Note that the full title of Categories A to C (as shown in 3.1.3) primarily relate to crewed aircraft operations. Uncrewed aircraft, including remotely piloted aircraft (RPA), fit into these categories as follows:

4. Definitions and examples of types of reportable matters
4.1. Introduction
4.1.1. Reportable matters are safety occurrences that involve the operation of an aircraft, including preparation for departure and during disembarkation.
4.1.2. Specifically, in relation to a particular crewed aircraft, reportable matters must occur during the period:
a. beginning when the aircraft is being prepared for take-off; and
b. ending when all passengers and crew members have disembarked after the flight.
4.1.3. For uncrewed aircraft, reportable matters must occur during the period:
a. beginning when the aircraft is ready to move with the purpose of flight; and
b. ending when the aircraft comes to rest at the end of the flight and the primary propulsion system is shut down. In the case of an uncrewed aircraft without a primary propulsion system (such as a gas balloon), the end of flight is when the aircraft comes to rest at the end of the flight.
4.2. Emergency declaration
4.2.1. A declaration of an emergency, in relation to an aircraft, means:
a. a declaration, by a flight crew member of the aircraft, of an alert phase (PAN PAN) or a distress phase (MAYDAY); or
b. a declaration by an air traffic service provider of a distress phase (DETRESFA) in relation to the aircraft.
4.3. Loss of separation standard between aircraft
4.3.1. A situation where the recognised separation standard (vertical, lateral or longitudinal) between aircraft that are being provided with an Air Navigation Service Provider separation service is infringed. This includes any of the following:
a. loss of procedural or surveillance separation standards
b. loss of prescribed runway or wake turbulence separation standards
c. visual reference is lost during visual separation by a pilot or air traffic controller in controlled airspace.
4.4. Serious property damage incident (external)

4.7. Aircraft incidents
4.7.1. Any event that is associated with the operation of an aircraft and affects, or could affect, the safety of the operation of the aircraft.
4.7.2. 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.
4.7.3. If an event, without correction, does not endanger the aircraft or its occupants, then the ATSB would consider that it has not affected or could not affect the safe operation of the aircraft (and therefore is an event that does not need to be reported).
4.7.4. Below are typical examples of aircraft incidents. For completeness, the list also includes occurrences that are aircraft accidents and/or reportable serious aircraft incidents, with notes to indicate this. However, the list is not exhaustive, and other operational events not in the list that meet the definition of an aircraft incident must be reported as aircraft incidents.

5. Guidance for determining injury and damage
5.1. Fatal aircraft-related injury
5.1.1. A fatal aircraft‑related injury is one where the person dies as a result of the injury within 30 days after the injury occurs, and the person suffers the injury as a result of:
a. being in the aircraft during the operation; or
b. direct contact during the operation with any part of the aircraft,including parts which have become detached from the aircraft; or
c. direct exposure to jet blast during the operation.
5.1.2. Fatal aircraft‑related injuries do not include:
a. the injury results from natural causes;
b. the injury is intentionally self-‑inflicted;
c. the injury is intentionally caused by another person;
d. the injury is to a person who is a stowaway in a part of the aircraft that is not usually accessible to crew members or passengers after take‑off.
5.2. Serious aircraft-related injury
5.2.1.A serious aircraft‑related injury is when a person suffers a serious injury as a result of:
a. being in the aircraft during the operation; or
b. direct contact during the operation with any part of the aircraft, including parts which have become detached from the aircraft; or
c. direct exposure to jet blast during the operation.
5.2.2. A serious injury is defined as an injury where any of the following apply:
a. the injury requires, or would usually require, admission to hospital, for more than 48 hours, within 7 days after the day when the injury is suffered;
b. the injury involves a fracture of any bone (other than a simple fracture of fingers, toes or nose);
c. the injury involves lacerations which cause severe haemorrhage or severe nerve, muscle or tendon damage;
d. the injury involves injury to any internal organ;
e. the injury involves second or third degree burns, or any burns affecting more than 5% of the body surface;
f. the injury involves exposure to hazardous chemicals, infectious substances or injurious radiation.
5.2.3. Serious aircraft‑related injuries do not include when:
a. the injury results from natural causes;
b. the injury is intentionally self‑inflicted;
c. the injury is intentionally caused by another person;
d. the injury is to a person who is a stowaway in a part of the aircraft that is not usually accessible to crew members or passengers after take‑off.
5.3. Guidance for the determination of aircraft damage
5.3.1. Use this excerpt from ICAO Annex 13 Attachment E for guidance when determining if aircraft damage is considered to be an accident.
a. If an engine separates from an aircraft, the event is categorised as an accident even if damage is confined to the engine.
b. A loss of engine cowls (fan or core) or reverser components which does not result in further damage to the aircraft is not considered an accident.
c. Occurrences where compressor or turbine blades or other engine internal components are ejected through the engine tail pipe are not considered accidents.
d. A collapsed or missing radome is not considered an accident unless there is related substantial damage in other structures or systems.
e. Occurrences of missing flaps, slats and other lift augmenting devices, winglets, etc., that are permitted for dispatch under the configuration deviation list (CDL) are not considered accidents.
f. Retraction of a landing gear leg or wheels-up landing, resulting in skin abrasion only, when the aircraft can be safely dispatched after minor repairs or patching, and subsequently undergoes more extensive work to effect a permanent repair, would not be classified as an accident.
g. If the structural damage is such that the aircraft depressurises, or cannot be pressurised, the occurrence is categorised as an accident.
h. The removal of components for inspection following an occurrence, such as the precautionary removal of an undercarriage leg following a low-speed runway excursion, while involving considerable work, is not considered an accident unless significant damage is found.
i. Occurrences that involve an emergency evacuation are not counted as accidents unless someone receives serious injuries or the aircraft has sustained significant damage.
Note 1.— Regarding aircraft damage which adversely affects the structural strength, performance or flight characteristics, the aircraft may have landed safely, but cannot be safely dispatched on a further sector without repair.
Note 2.— If the aircraft can be safely dispatched after minor repairs and subsequently undergoes more extensive work to effect a permanent repair, then the occurrence would not be classified as an accident. Likewise, if the aircraft can be dispatched under the CDL with the affected component removed, missing or inoperative, the repair would not be considered as a major repair and consequently the occurrence would not be considered an accident.
Note 3.— The cost of repairs, or estimated loss, such as provided by insurance companies may provide an indication of the damage sustained but should not be used as the sole guide as to whether the damage is sufficient to count the occurrence as an accident. Likewise, an aircraft may be considered a ‘hull loss’ because it is uneconomic to repair, without it having incurred sufficient damage to be classified as an accident.

7. Protecting of evidence for investigations
7.1.1. The TSI Act provides powers to ATSB transport safety investigators to obtain information necessary to conduct investigations into reportable matters. However, investigations always seek, where possible, to obtain information in cooperation with the owner.
7.1.2. The TSI Act makes provision for an offence if a person engages in reckless conduct that adversely affects an investigation that is either being conducted at that time or could be later conducted into an immediately reportable matter. Practically, this means that potential evidence relating to all immediately reportable matters must be protected, including recorded data (flight recorder, cockpit voice recorder, air traffic communications etc), wreckage and damaged parts, and related documents, unless authorised by the ATSB or informed that the ATSB will not be investigating the matter.
7.1.3. Similarly, the ATSB may issue a ‘protection order’ for the purpose of protecting evidence that might be relevant to an investigation. This may direct that specified things, or things in a specified class of things, must not be removed or interfered with except with the permission of the ATSB.
7.1.4. These provisions do not apply if the conduct was necessary for any of:
a. to ensure the safety of persons, animals or property
b. to remove deceased persons or animals from an accident site
c. to move a transport vehicle, or the wreckage of a transport vehicle, to a safe place
d. to protect the environment from significant damage or pollution.
