Sunday, July 1, 2001 7:05 PDT
NTSB Narrative Summary Released at Completion of Accident
The airplane nosed over during a forced landing following a loss of engine power while in cruise flight. The engine lost power 2 days prior to the accident due to an internal magneto timing problem. The magneto timing was reset and the airplane was returned to service. A post accident examination of the engine revealed the magneto contact points would not open. The magneto was retimed and found to operate normally. According to the maintenance records, a 100-hour inspection took place 3.1 hours prior to the accident. The earlier magneto maintenance adjustment took place at an unknown time between the 100-hour inspection and the accident flight.
NTSB Probable Cause Narrative
the loss of engine power while in cruise flight due to the mechanic's improper magneto timing.
