Engine Power Loss During Landing Leads to Collision Short of Runway (N93111)

Accident Overview

A pilot established an approach and landing profile for a full stop landing. During the approach, the engine lost power when the throttle was reduced to idle. The pilot attempted to restore full power, but those efforts were unsuccessful. When the pilot retracted the wing flaps, the airplane developed a sink rate. The pilot continued the final approach, and the airplane collided with the ground 300 feet short of the runway surface.

Post-Accident Examination

During the post-accident wreckage examination, several gallons of fuel were recovered from the fuel system. Examination of the airplane failed to disclose a mechanical problem. The engine assembly was subsequently started and operated on the airframe. The engine operated through the entire power range. No mechanical problems were noted with the engine during the operational check.
