Probable cause

The total loss of engine power during initial climb due to a fracture and failure of the engine starter ring gear. A contributing factor which was related to the mechanical failure was the airplane owner's inadequate maintenance.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The experimental airplane was owned and operated by the pilot. The pilot reported that he experienced a total loss of engine power at about 200 feet above ground level during initial climb. The pilot made a forced landing and collided with a berm. An examination of the airplane revealed its starter ring gear had failed where it had been welded to the engine flywheel (flexplate).
