Incident Overview
During the climb after takeoff, as the aircraft reached an altitude of 2,000 feet, the engine ceased operating abruptly. The pilot attempted to restart the engine but was unsuccessful. Subsequently, a forced landing was executed on a golf course. During the landing, the aircraft struck trees.
Examination Findings
A postcrash examination of the engine was conducted. The left magneto was found to be non-rotatable. The left crankshaft idler gear and crankshaft gear exhibited broken teeth due to overload, and the crankshaft gear had become loose. Inspection of the left magneto revealed that the rotating magnet had a defect that caused it to come into contact with the magneto case. The precise nature of the defect was not determined. The magneto had accumulated 2.3 flight hours since its last overhaul.
