Narrative:
During takeoff, the airplane sustained a partial loss of engine power and overran the runway after the pilot lost cockpit throttle control. Postaccident examination of the airplane revealed a throttle control pin lying on the cockpit floor. A cotter pin for the throttle control pin was missing; the length of time it had been missing could not be determined.

Probable Cause: The loss of engine throttle control during takeoff due to an unsecured cockpit throttle control pin, which resulted in a runway overrun.
