Aircraft Accident/Incident Report

Yerington, Nevada 89447
Sunday, April 18, 1999 11:30 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot indicated that no malfunctions were noted during the pretakeoff engine run-up, and, on initial climb, between 100 and 200 feet above the ground, the engine 'bogged down.' The pilot stated that he tried to regain power by adjusting the throttle and mixture controls, but 'nothing happened.' Because engine power was not restored the pilot aborted the flight. Responding sheriff deputies observed evidence that the airplane struck the ground about 803 feet north of the runway's departure end, then impacted an irrigation ditch before coming to rest 97 feet north of the ditch. The airplane was subsequently examined by the FAA, and no evidence was found of any blockage in the fuel system screens or lines. The throttle and mixture controls were intact and functional. The magnetos operated normally. The engine was operated to a low power level, and no malfunctions were noted. The fuel tanks were found at least half full of fuel. Also, no anomalies were found with the fuel selector handle. A density altitude of 5,800 feet was computed.

NTSB Probable Cause Narrative

The partial loss of engine power due to the pilot's failure to properly lean the engine for the high density altitude takeoff.
