While descending to Phoenix Airport, both engines failed. The pilot performed an emergency landing short of the field. The aircraft was damaged beyond repair; the pilot was unhurt. Fuel mismanagement was identified as the cause.

Event Details

A single-pilot aircraft experienced a simultaneous failure of both engines while descending to Phoenix Airport. The pilot promptly reduced altitude and initiated an emergency landing, touching down a few miles from the airfield.

Engine Failure and Emergency Landing

The engines failed completely, leading to a loss of thrust. The pilot attempted a forced landing off-airport on land. During the landing, the aircraft came to rest on its belly. The pilot was able to escape unhurt.

Aircraft Damage

The aircraft sustained substantial damage and was deemed beyond repair. The tip tanks separated and burned during the event. Post-accident examination revealed that the left auxiliary tank was empty and the right auxiliary tank was demolished.

Probable Cause and Contributing Factors

The official probable cause is a controlled collision with the ground following a mismanagement of fuel. Contributing factors include fuel starvation, failure to follow approved procedures, improper emergency procedures, wet and soft ground, complete failure of both engines, forced landing off airport on land, and the pilot not recalling changing the fuel selector after power loss.
