Aircraft involved
Probable cause & findings
The pilot’s inadequate fuel planning, which resulted in a loss of engine power due to fuel exhaustion. Contributing to the accident was the pilot's improper execution of an autorotation, which resulted in a hard landing.
Factual narrative
While returning back to his home field, the single-engine helicopter's engine began sputtering. The private pilot began looking for an open area to perform a precautionary landing. While descending for an unoccupied football field, the engine quit. The pilot continued the autorotation to the field. During the landing, the helicopter landed hard and spun counterclockwise before coming to rest in the upright position. Substantial damage was sustained to the tailboom. During an on-scene examination of the helicopter, the fuel tanks were both found empty. No fuel was found underneath the wreckage or on the field. After adding fuel to the engine the helicopter operator was able to run the engine at various engine settings with no anomalies. In addition, the fuel low light passed functional testing. According to the pilot, while returning back to his home airport the helicopter's engine began to sputter. He elected to perform a precautionary landing and, while descending to an unoccupied football field, the engine lost total power. During touchdown, the helicopter landed hard and spun counterclockwise before coming to rest in the upright position, substantially damaging the tailboom. An on-scene examination of the helicopter revealed that both fuel tanks were empty and that no fuel was observed underneath the wreckage or on the field. After adding fuel, the engine the helicopter operator was able to run the engine at various power settings with no anomalies. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
