Aircraft: Beechcraft Skipper. Injuries: 2 Minor. Location: Clark, S.D. Aircraft damage: Substantial.
What reportedly happened: The passenger reported that the airplane’s low fuel light illuminated during the flight.
She stated that they continued the flight and were circling to land on a grass runway when the airplane crashed.
A witness reported seeing the airplane pass over the runway at a low altitude with the engine operating. The airplane then abruptly climbed and initiated a turn.
A witness on the ground said the airplane’s nose dropped as if it had stalled and then descended and crashed.
There was no bending of the blades of the engine’s propeller, indicating that the engine was not producing power at the time of the impact.
Both fuel tanks ruptured, and only one gallon of fuel was recovered at the scene. No fuel was found in the gascolator or carburetor. No fuel odor was present at the accident site.
The airplane maintenance manual indicated that one gallon of the airplane’s fuel supply was unusable fuel.
Investigators determined it is likely that the engine lost power during the landing approach due to fuel exhaustion and that the pilot failed to maintain airspeed after the power loss, resulting in an inadvertent stall.
Probable cause: The pilot’s improper fuel management, which led to fuel exhaustion, and his failure to maintain adequate airspeed resulting in an aerodynamic stall.
