What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.4)While in cruise flight, the pilot experienced a partial power loss and performed a precautionary landing. During the landing to uneven terrain, the airplane came to rest inverted. Examination of the engine revealed a 2 to 3 inch crack in the vicinity of the 'number one' cylinder. At the time of the accident, the engine was approximately 53 years old, with 1,778 hours of operation since its last overhaul in 1961. (-23) pilot departed weedsport airport (B16), NY at 9:20 am and flew to tri-cities (czg), edicott, NY, to pick up a passenger. He then departed tri-cities (czg) and flew to bloomsburg municipal (N13), PA, where he landed for lunch. He then departed bloomsburg muni (N13) enroute to Skyhaven Airport (76N), PA. When he heard the engine start to run rough and the oil pressure started to drop, pilot made an emergency landing in field and, on roll out, the aircraft hit a rut and flipped over on itself. On removal of cowling in the field, there was a fresh coating of oil over the entire engine and engine compartment. On inspection, we were unable to detect where the engine oil was coming from.
