Analysis

The aircraft collided with an irrigation pipe line and fence during rollout of a forced landing after engine failure. The engine stopped while the aircraft was cruising en route. The pilot remained in radio contact throughout the emergency and landed in a field of grain stubble and new crops. An engine teardown revealed a hole in the #4 piston. This hole had pressurized the crankcase forcing oil out of the breather until oil depletion caused engine stoppage. Also, a trace of carbon tracking was found on the right distributor block from the #4 location to another stationary electrode.
