Airworthiness date: 15-Jan-1979.

Incident: Barrow, Alaska 13-Apr-1989. The airplane had just departed on a scheduled commuter flight with five passengers and two crew members on board. Upon reaching an altitude of 15,000ft, the control yoke was pulled forward out of the captain's hands and pinned against the control panel. Simultaneously, the nose of the airplane suddenly pitched up 60 degrees above the horizon. The captain reduced power and the nose pitched 30 degrees below the horizon. The flight crew was eventually able to maintain a level attitude by power adjustments alone, and returned for a safe landing. Inspection revealed a fatigue fractured elevator bellcrank mounting quadrant, resulting in a complete loss of elevator control. The elevator bellcrank mounting quadrant had been in service since 1966 and had been operating 17,826 hours. The fracture occurred between the vertical stabilizer stub fin attachment bulkhead and the bellcrank. Subsequent metallurgical exam revealed multiple fatigue origins in the vicinity of superficial machining abrasions. Damage may have been induced during a storm where the aircraft was parked tail into the wind.
