Accident Overview
During an aborted takeoff, the airplane overran the runway and collided with soft terrain. The pilot reported that preflight, engine start, and engine run-up were normal. At 85 knots, the pilot attempted to rotate the airplane by pulling back on the yoke. The yoke moved only slightly, and the airplane would not rotate. The pilot pulled again hard but still no rotation. He then cut the throttle and applied full brakes.
Aircraft Damage
The airplane traveled off the end of the runway, across a road, and into a plowed field. Upon impact with the field, the nose gear collapsed and both main gears separated from the airplane.
Inspection Findings
Inspection of the airplane revealed no failure or malfunction of the flight control systems. However, inspection of the engine disclosed that the three screws securing the magneto harness cover on the right magneto were missing, and the harness was backed away from the magneto. Additionally, the turbine in the turbocharger was dragging when the pilot attempted to spin it by hand. A teardown of the turbocharger revealed a build-up of carbon in the heat shield.
