Aircraft Accident/Incident Report

Lexington, Kentucky 40510
Friday, June 9, 2000 14:00 EDT

NTSB Narrative Summary Released at Completion of Accident

While on approach to airport, the flightcrew experienced a total failure of the left engine, followed by a fire in the left engine. The flightcrew secured the engine, extinguished the fire, and made and uneventful landing. Review of the failed engine revealed that the bull gear had separated into several pieced. Metallurgical examination of the bull gear teeth root revealed beachmarks, consistent with fatigue. Further examination revealed non-uniform wear of the bull gear teeth and high speed pinion gearshaft teeth. The non-uniform wear was consistent of a misalignment between the bull gear and high speed pinion shaft.

NTSB Probable Cause Narrative

A misalignment between the bull gear and high speed pinion gearshaft, which resulted in fatigue and a subsequent failure of the bull gear.
