aviation accidents

Probable cause: The pilot’s improper fuel planning, which resulted in a total loss of engine power due to fuel exhaustion.

Probable cause: A failure of the right fuel tank to supply fuel to the engine for reasons that could not be determined, which resulted in a total loss of engine power due to fuel starvation.

Probable cause: The pilot’s controlled flight into mountainous terrain while attempting to operate under visual flight rules in instrument meteorological conditions (IMC).

Probable cause: The reciprocating engine’s exhaust valve being stuck in the “open” position, which resulted in a partial loss of engine power during initial climb.

Probable cause: Maintenance personnel’s failure to properly secure the vacuum pump, which resulted in a loss of engine oil and the subsequent total loss of engine power due to oil starvation.

Probable cause: The pilot’s loss of airplane control while conducting aerobatic flight maneuvers with insufficient altitude to recover.

Probable cause: The student pilot’s improper landing flare in gusting crosswind conditions, which resulted in a hard landing.

Probable cause: A partial loss of engine power due to fuel contamination from an undetermined source.

Probable cause: The loss of engine power for reasons that could not be determined because postaccident examination and testing of the engine did not reveal any anomalies that would have precluded normal operation.
