What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While in cruise flight, in the local area of the pilots home base, the aircraft developed a severe vibration. The pilot initiated an emergency landing in a grass field. The landing was uneventful and the aircraft engine came to a stop. Oil was dripping from the cowling area and when cowl was removed a hole was found in the upper crank case. Engine has been sent for tear down analysis. Initial investigation of the engine points to the possibility of a spun bearing which caused overheating of bearing journal and catastrophic engine failure.
