Probable cause
The pilot's failure to properly maintain the airplane and engine, which resulted in a total loss of engine power due to improperly installed magnetos and a broken camshaft.
NTSB analysis
The private pilot said the airplane was in cruise flight when the engine made an unusual grinding noise and then stopped producing power. The pilot made a forced landing to a field. During the emergency descent, the airplane struck a power line with the left main landing gear and landed hard. Examination of the engine revealed that the magnetos were not properly secured to the engine and that the camshaft was broken. A review of the engine maintenance logbook revealed the airplane's most recent annual inspection was completed in January 2008, almost 5 years before the accident.
