Investigation Summary
The flight was a charter intended to transport students from The Scots College to Norfolk Island for Anzac Day commemorations. Shortly after liftoff from runway 16, the crew heard popping sounds and experienced a leftward yaw. Although the captain feathered the left propeller and maintained full power on the right engine, the aircraft failed to climb. The investigation by the Bureau of Air Safety Investigation (BASI) highlighted that the aircraft was in an overweight condition, which, combined with the handling pilot's inability to achieve optimum asymmetric performance, prevented the vintage airliner from maintaining flight. The ditching was executed near the southern end of the then-under-construction runway 16L. While the ditching was successful and resulted in no fatalities, the captain, Rod Lovell, faced significant professional repercussions and spent decades disputing the findings, particularly the allegations regarding the aircraft's weight and his handling of the emergency.
Final Conclusions
The Bureau of Air Safety Investigation (BASI) concluded that the primary cause was a substantial power loss in the left engine due to a stuck inlet valve. The investigation identified the handling pilot's failure to obtain optimum asymmetric performance as the culminating factor. Contributing factors included the aircraft being operated above its maximum takeoff weight, maintenance errors during engine overhaul, and non-adherence to standard operating procedures. The report also cited organizational failures within the operator and inadequate regulatory oversight by the Civil Aviation Authority (CAA).

Airframe & Maintenance
Systems & Failure Modes
Pratt & Whitney R-1830-92 Engine
The left engine suffered a power loss when an inlet valve became stuck in the open position, preventing normal combustion.
Propeller Feathering System
The crew successfully feathered the left propeller to reduce drag, but the aircraft still could not maintain altitude.
Interesting Facts
- 01The aircraft was 50 years old at the time of the accident, manufactured in 1944.
- 02All 25 people on board survived, with only one serious injury reported (a flight attendant).
- 03The ditching occurred approximately 46 seconds after the pilot first reported the emergency to ATC.
- 04The aircraft was chartered to transport a school band for Anzac Day celebrations on Norfolk Island.
- 05The investigation found the aircraft was in an overloaded (overweight) condition at takeoff.
Safety Actions & Advisories
Regulatory Oversight Reform
Source ↗The investigation identified significant failures in the Civil Aviation Authority's (CAA) monitoring of charter operators, leading to recommendations for improved communication between regional offices and better training for regulatory staff.
Maintenance Management Improvements
Source ↗BASI issued interim safety recommendations regarding engine overhaul procedures and maintenance management to address the errors that led to the stuck inlet valve.
Operational Procedure Standardization
Source ↗Recommendations were made to ensure stricter adherence to standard operating procedures and to improve the training and skill assessment of pilots operating vintage multi-engine aircraft under charter certificates.
Known Controversies & Unanswered Questions
Pilot Dispute of BASI Findings
Reference ↗Captain Rod Lovell has spent over 25 years disputing the official report, claiming the aircraft's power loss was more severe than acknowledged and that the weight allegations were inaccurate, citing simulator tests in 2018 to support his case.
