What happened
The aircraft touched down on soft terrain approximately 1500 feet short of the runway threshold. This landing occurred immediately following a complete loss of engine power during the approach phase.
The investigation
Post-accident examination revealed that the fuel boost pumps, which are located within the main fuel tanks, were unable to supply fuel to the engines at a sufficient rate to facilitate an engine restart. The pilot reported that he did not utilize the fuel stored in the auxiliary tanks during the flight.
Findings
The sequence of events was driven by fuel exhaustion in the main fuel tanks. The pilot failed to switch to the auxiliary fuel tanks as required, leading to a total depletion of usable fuel. Consequently, the pilot was unable to maintain power or restart the engines after the initial failure.
