Aircraft Accident/Incident Report

Cottonwood, Arizona 86326
Thursday, June 20, 2002 6:50 MST

NTSB Narrative Summary Released at Completion of Accident

During initial takeoff climb, the pilot heard a "loud bang" from the engine, followed by a smell of fuel in the cockpit, a loss of fuel pressure, and a substantial engine vibration. During an attempt to return to the airport, the engine lost power, and the pilot initiated a forced landing. During the landing, the airplane impacted a cattle gate and came to rest on its nose. Examination of the engine revealed that the #1 lower connecting rod bolt was fractured at the bolt's dowel section, which corresponded with the connecting rod and rod cap split line. According to the engine manufacturer's metallurgist, the fracture initiated at the outer diameter of the bolt's dowel section, and the fracture progressed in fatigue until the bolt fractured as a result overstress. The bolt's dowel section exhibited fretting damage at the fracture origin. At the time of the accident, the engine had accumulated 9.64 hours since the annual inspection, and 195.84 hours since major overhaul.

NTSB Probable Cause Narrative

The loss of engine power as a result of the failure of the #1 lower connecting rod bolt due to fatigue.
