Investigation Summary
The flight was the return leg of an aeromedical retrieval from Samoa to Melbourne. During the flight, the crew encountered stronger-than-expected headwinds and deteriorating weather at Norfolk Island. Despite receiving reports of low cloud and visibility below landing minima while 160 NM out, the crew elected to continue to the island rather than divert to Noumea, believing they could land safely. Upon arrival, the crew conducted four instrument approaches (two to runway 29 and two to runway 11) but could not establish visual contact with the runway. With fuel exhausted, the Pilot in Command (PIC) performed a controlled ditching. The evacuation was complicated by the lack of life jackets for the First Officer and the patient, and the absence of formal procedures for securing life rafts in the cabin. The investigation was initially closed in 2012 but was reopened in 2014 following a Senate inquiry that criticized the ATSB for failing to retrieve the flight recorders and for placing undue blame on the pilot while ignoring systemic regulatory and operator failures.
Final Conclusions
The reopened investigation (Final Report AO-2009-072, released November 23, 2017) concluded that the PIC did not plan the flight in accordance with regulatory requirements, which precluded a full understanding of the risks. However, it also identified significant systemic factors: Pel-Air's risk controls were inadequate, and CASA's oversight of the operator was deficient. Additionally, air traffic services in Nadi and Auckland failed to proactively provide the crew with updated weather forecasts that would have indicated the need for a diversion before the aircraft reached its point of no return.

Airframe & Maintenance
Systems & Failure Modes
Fuel Planning
The aircraft was loaded with full main tanks, but higher-than-expected headwinds and the lack of a designated alternate airport left no margin for multiple missed approaches.
Flight Recorders (CVR/FDR)
Located in the tail section, these were recovered from the seabed in November 2015 and provided critical data for the reopened investigation.
Survival Equipment
The aircraft lacked specific storage for the patient's life jacket and formal procedures for securing life rafts during a ditching, which delayed the evacuation.
Interesting Facts
- 01The aircraft was an air ambulance flight classified as 'aerial work,' which had lower fuel and planning requirements than 'charter' flights.
- 02The pilot used a pocket torch to signal rescuers after the ditching.
- 03The ATSB initially declined to recover the flight recorders, citing depth and cost, but recovered them in 2015 after the case was reopened.
- 04The 2013 Senate inquiry found evidence that CASA had withheld critical audit documents from the ATSB during the initial investigation.
- 05The final 2017 report spanned 531 pages, making it one of the longest in ATSB history.
Safety Actions & Advisories
Regulatory Reclassification
The investigation highlighted the disparity between 'aerial work' and 'charter' requirements, leading to calls for stricter fuel and planning standards for aeromedical flights.
ATSB Investigative Reform
Following the TSB Canada review, the ATSB updated its methodologies to ensure systemic factors and organizational failures are more thoroughly examined.

ATSB and CASA Collusion Allegations
Reference ↗A 2013 Senate inquiry found that CASA deliberately withheld the 'Chambers Report' (which was critical of CASA's own oversight) from the ATSB, and alleged the two agencies colluded to blame the pilot.
