On January 2, 2000, a Piper PA-46-310P (registration N4389W) was involved in an aviation accident near Odessa, TX. Investigators recorded the probable cause as: Fatigue failure of the #1 piston pin, which resulted in its separation and subsequent engine failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An airplane experienced a total loss of engine power during climb through 9,000 feet. The pilot performed an unsuccessful restart and executed a forced landing. Investigation revealed a fatigue failure of the #1 piston pin.
Overview
During climb through 9,000 feet after departure, the airplane’s engine lost total power. The pilot attempted to restart the engine but was unsuccessful, subsequently executing a forced landing north of the departure airport.
Engine Examination
Postaccident examination of the airplane revealed a hole in the engine crankcase behind the #2 cylinder. The #1 piston pin had separated at its midpoint. Further examination of the engine showed that the #1 piston pin failed as a result of fatigue. The #1 connecting rod bushing (piston pin end) was found fragmented in the oil sump.
Findings
The fatigue failure of the #1 piston pin led to its separation, causing a breach in the crankcase and total engine power loss. The fragmented connecting rod bushing was consistent with the piston pin failure.
Probable cause
Fatigue failure of the #1 piston pin, which resulted in its separation and subsequent engine failure.
