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 airplane was being operated as an agricultural aircraft when the engine started backfiring and then quit. During the forced landing in a plowed field, the airplane flipped forward to the inverted position. Investigation revealed the teeth on the left magneto were all broken off. A new magneto and a propeller were installed and after ground run, the engine operated normally. After replacement of the rudder, the airplane was flown out of the field. After replacement of the engine, the airplane will be returned to service.
