| Confidence Rating: |  Accident investigation report completed and information captured |
During cruise flight, the pilot of a Grumman-Schweizer G-164B airplane noted that the engine began to run rough, and shake violently. He also noted smoke coming from the exhaust. The engine subsequently lost power, and the pilot performed an emergency landing to a cornfield. During the landing, the airplane came to rest inverted, resulting in substantial damage. A post-accident examination of the engine revealed a fractured masterod. Deformation and damage to the masterod was consistent with being exposed to a hydraulic lock prior to the accident flight.
Probable Cause: A failure of the masterod, due to a hydraulic lock on a previous flight, which resulted in a total loss of engine power.
