Aircraft Accident/Incident Report

West Middlesex, Pennsylvania 16159
Sunday, April 8, 2001 19:00 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot took off towards the south, flew a left downwind leg, then turned west onto a left base leg. At the time, he was maintaining a 500-foot altitude, and 6,000 rpm on the airplane's Rotax 503 engine. As the airplane continued along the base leg, it began a descent. While passing through 400 feet, the engine experienced a partial power loss, and thereafter would not provide any more than 3,000 rpm. The airplane continued its descent, and struck power lines that approximately paralleled the runway, at a height of 60 feet. It subsequently impacted the ground, and was consumed by fire. Post-flight inspection revealed that the engine rotated freely; however, due to its condition, further engine examination was not performed. Winds at the time of the accident were from 270 degrees true, at 14, gusting to 19 knots. There were woods and houses to the north of the base leg, and a house to the south.

NTSB Probable Cause Narrative

The partial loss of engine power, for undetermined reasons. Factors included the headwinds on base leg, and the unsuitable terrain for a forced landing.
