On September 26, 1989, a Piper PA-25-235 (registration N4450Y) was involved in an aviation accident near Warner Springs, CA. Investigators recorded the probable cause as: The pilot's failure to maintain adequate fuel reserves, which resulted in fuel exhaustion and loss of engine power during flight. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A Cessna 182 lost engine power on final approach after a glider tow flight and crashed into trees short of the runway, killing the pilot.
What happened
The pilot departed an airfield for a glider tow flight with approximately 10 gallons of fuel remaining in the aircraft's tanks. After releasing the glider at altitude, the pilot turned back toward the airport to land. While established on final approach to the runway, the engine suddenly lost power. The pilot attempted to glide the aircraft toward the runway but was unable to make it. Before reaching the paved surface, the aircraft struck a tree and crashed.
Findings
Post-accident examination of the airframe revealed no mechanical anomalies that would have precluded normal operation. The investigation could not determine the specific reason for the loss of engine power during flight. The pilot's fuel estimate at departure was noted as a key factor in the sequence of events leading to the accident.
Safety message
Pilots towing gliders must account for the additional fuel burn associated with the tow operation and ensure sufficient reserves remain for the return leg and landing. Accurate pre-flight fuel planning is critical when operating in a dual-purpose role.
Probable cause
The pilot's failure to maintain adequate fuel reserves, which resulted in fuel exhaustion and loss of engine power during flight.
