Probable cause
Operation of an aircraft with known deficiencies and deterioration/failure of the magneto(s). Factors related to the accident were: the lack of an annual inspection and non-compliance with an airworthiness directive (AD).
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
Pilot experienced a partial loss of engine power and was attempting a precautionary landing when engine quit totally. Pilot made forced landing in corn field and nosed over during landing roll. Investigation revealed that pilot was ferrying aircraft for owner who had just purchased it. No log books could be found. It could not be determined when last annual inspection had been performed. Engine investigation determined that the right magneto was inoperative, and that the left magneto was deteriorated, and would short out and fail when it was brought up to operating temperature. Magneto AD issued in 1973 had not been complied with. There was no record of any ferry permit requested.
