Aircraft Accident/Incident Report

Graham, Oklahoma 73401
Thursday, July 28, 2005 15:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The 306-hour pilot noticed that the oil pressure gauge indicated low and in the red operating range area while in cruise flight. The pilot elected to initiate a precautionary landing into a nearby open field. During the approach to the field, as the airplane descended closer to the ground, the pilot noted more obstructions. To avoid colliding with power lines, the pilot intentionally stalled the airplane at about 20 feet above the ground and landed hard, with power-on and full-flaps. Examination of the engine revealed that oil was leaking from a failed generator mounting gasket. No oil was observed on the dipstick for the engine crankcase.

NTSB Probable Cause Narrative

The impending loss of engine power as result of the failure of the generator mounting gasket resulting in engine oil starvation. A contributing factor was the lack of suitable terrain for the precautionary landing.
