Event Summary
After lift-off from an unspecified runway, at approximately 100 feet above ground level and 85 knots, the left engine decelerated. The airplane began to yaw and roll left. The pilot in command (PIC) aborted the takeoff, turned left, and executed a landing on a flat level field. During the landing rollout, the airplane struck a fence, followed by trees.
Engine Examination Findings
Following the event, examination of the left engine revealed that the loss of power was attributed to a fatigue fracture of a compressor turbine blade, which led to subsequent blade fractures.
The right engine was also examined. It was found to have advanced wear on the throttle cam assembly of the power turbine governor. In a test cell, the right engine could achieve only approximately 28% of takeoff power. The cam lobe wear had progressed over an extended period of time. The right engine propeller governor had been replaced on November 18, 1990, followed by a test run.
