This Aviation Safety Occurrence Report documents an engine failure incident involving PC-9/A aircraft A23-039 during a Flying Instructors Course Navigation exercise near East Sale on 18 May 2011. The aircraft experienced a sudden loss of power approximately six miles outbound at 3,000 feet AMSL, followed by the crew declaring a Mayday. After an unsuccessful landing approach, both crew members ejected successfully and the aircraft crashed short of runway 04. The investigation, completed by the Defence Aviation Safety Authority, identified the root cause as fuel starvation resulting from High Pressure Fuel Pump failure. Analysis revealed the pump drive splines exhibited mechanical wear in the drive teeth engaging the coupling shaft, likely accumulated over time rather than from instantaneous failure, preventing the engine from generating sufficient power. Core engine components showed no catastrophic damage. The report references a detailed Accident Investigation Report held by Air Training Wing.
