Accident Overview
On approach to Henderson-Sky Harbor Airport, the pilot of a twin-engine airplane experienced technical problems with the fuel supply system. While on final approach, the aircraft stalled and subsequently crashed in a rocky area located one mile short of the runway. The airplane burst into flames upon impact. The pilot, who was the sole occupant, was killed.
Probable Cause and Contributing Factors
The probable cause of the accident was a stall on traffic pattern-circling after the pilot-in-command failed to maintain flying speed. Several contributing factors were identified:
- The pilot-in-command attempted operation with known deficiencies in equipment.
- Fuel system issues were noted, including a wingtip tank sniffer valve o-ring seal that had failed before the flight.
- Material failure was involved.
- Air traffic control failed to advise the pilot of unsafe airport conditions.
- Airport facilities were cited as a contributing factor.
- The pilot attempted a precautionary landing on the airport.
- The aircraft was low on fuel.
- The flight was diverted to an unlighted runway.
Sequence of Events
During the approach, the pilot encountered difficulties with the fuel supply system. Despite the technical problems, the pilot continued the approach. On final, the twin-engine airplane stalled and was unable to reach the runway, crashing in a rocky area approximately one mile short of the runway. The post-crash fire destroyed the aircraft.
