Aircraft Accident/Incident Report

Kingman, Arizona 86401
Friday, April 11, 2008 7:30 MST

NTSB Narrative Summary Released at Completion of Accident

About 15 minutes after takeoff, during cruise flight, the pilot observed the engine oil pressure drop and the temperature increase, followed by a total loss of engine power. The pilot made an intentional gear-up forced landing on rough terrain. A partial teardown examination of the engine revealed ferrous and non-ferrous metal in the oil screens. The number 3 connecting rod was found bent, and the number 4 and number 5 cylinders were damaged. Numerous pieces of metal were observed in the crankcase that were associated with the number 4 and number 5 cylinders and pistons. The internal engine component that initially broke at the beginning of the sequence was not identified.

NTSB Probable Cause Narrative

A total loss of engine power during cruise flight due to an undetermined catastrophic internal engine failure.
