Safety Issue Description

AGAIR management exercised ineffective operational control over the line scanning activities. As a result, the ongoing intermittent pressurisation defect was not formally recorded, the issues with the aircraft were not communicated to the AGAIR safety manager, and the hazardous practice of operating the aircraft at a cabin altitude that required the use of supplemental oxygen, without access to a suitable oxygen supply, was allowed to continue.

Issue Status Justification

Implemented actions do not address, in full, the matters raised within the safety issue.

Action description

AGAIR stated that it has ceased line scanning activities. AGAIR also stated that the organisation’s exposition has been amended to address the matters raised within the safety issue. This included the insertion of the following information:

  • the AGAIR exposition amended in Vol 1, 1.3.5.2 and 1.3.6.2 to include the following statement;
    ‘The HOFO [(head of flying operations)] may delegate any of their responsibilities to other members of the Company however this does not absolve the HOFO of the responsibility. The HOFO must ensure that the person has sufficient knowledge and experience to perform the delegated role. The CEO [(chief operating office)] shall ensure a [notice] is issued via Air Maestro advising staff of the shared responsibilities and the timeframe to which this will occur.’
  • the AGAIR exposition Vol 6, 6.2.10 amended to include the following statement;
    ‘When operating pressurized aircraft, the cruising altitude must be no higher than required to ensure the cabin altitude as displayed on the pressurization controller does not exceed 10,000 feet’.
  • the AGAIR exposition Vol 2, 2.19.3 amended to include the following statement
    ‘On completion of the days flying the Pilot-in Command is to ensure that the days total flight time is logged together with the aircraft’s total time in service, number of landings and engine cycles as appropriate, and cabin differential pressure where applicable. The fuel and flight log is included within the maintenance release folder and forwarded to flight operations monthly for review by the HOFO. Any daily variations noted by the PIC are to be reported to the HOFO while any trend variance from previous figures will warrant investigation and reporting to the Safety Manager. Any maintenance action shall be initiated via the HAAMC [(head of aircraft airworthiness maintenance control)].’ 

AGAIR advised the ATSB that the ‘aircraft daily fuel & flight log’ has been amended to include a column to record the cabin differential during pressurised cruise flight.

AGAIR has also incorporated ‘pressurisation system failure’, ‘oxygen system failure’, ‘hypoxia’, and ‘any hazards unique to multispectral imaging/line scanning operations’ into the organisation’s hazard register. 

Additionally, AGAIR advised the ATSB that it has made changes to its recruitment process.

ATSB Response

While the ATSB recognises the changes implemented by AGAIR to date, the actions taken do not address, in full, the matters raised within the safety issue relating to effective operational control. The HOFO was responsible for ensuring the operation was compliant with aviation legislation and conformed to company standards. However, the ATSB found multiple instances where these requirements were not met. The response from AGAIR does not address how the organisation intends to assure future legislative and procedural compliance by line pilots and management personnel.

Action description

The ATSB recommends AGAIR initiates an independent review of their organisational structure and oversight of operational activities to assure ongoing effective operational control by management.
