Aircraft Accident/Incident Report

Flagstaff, Arizona 86004
Saturday, June 5, 2004 15:50 MST

NTSB Narrative Summary Released at Completion of Accident

The airplane collided with ground obstructions during a forced landing following a loss of engine power. While in cruise flight the pilot observed a decrease in the engine manifold pressure. He adjusted the throttle to increase the manifold pressure, but the pressure continued to drop. He observed that the oil pressure was also low. The pilot declared an emergency and attempted to land at a nearby airport. The engine lost all power about 13 miles northeast of the airport and the pilot performed a forced landing on a highway. During the landing rollout the right wingtip contacted a highway guardrail and the wing was torn off the fuselage. Examination of the engine disclosed that the failure was due to oil exhaustion. The turbocharger oil drain line fitting gasket and o-ring was brittle and was broken. This allowed the oil to leak from the turbo charger, resulting in the loss on engine power.

NTSB Probable Cause Narrative

oil exhaustion due to a leak from the bottom oil drain line gasket and o-ring for the turbo charger.
