Confidence Rating: | Accident investigation report completed and information captured |
Narrative: The pilot reported that during maneuvering flight, at about 500 feet agl, and 1/2 mile offshore, the engine and cowling began to shake, the engine began to sputter, and the windscreens became covered with oil. He made a turn westbound toward land, and declared an emergency, intending to land at the nearest airport. He reported the engine power available would not sustain level flight, and he started a slow descent. Neither the pilot nor his front seat passenger acquired a visual on the airport. The pilot overflew the airport and forced landed in a residential area 2 miles west of the airport. Examination of the engine revealed failure of the 12 cylinder holddown studs of the No. 7 cylinder.
Probable Cause: The pilot's failure to select a suitable forced landing site following a partial loss of engine power due to failed cylinder holdddown studs, and the subsequent collision with trees. A factor in the accident was the reduced forward visibility from the dual open cockpits due to windshield obscuration by engine oil.
