Accident Details
Shortly after departing, the aircraft's engine experienced a reduction in revolutions per minute and eventually ceased operation. The flight instructor, who was at the controls, identified the only available landing area in the vicinity. This field was situated on the side of a hill and had a surface that was rough, uneven, and covered with rocks. The instructor executed a forced landing in this area.
Injuries and Damage
As a result of the forced landing, the aircraft was completely destroyed. All three individuals on board suffered serious injuries.
Investigation Findings
A teardown examination of the engine was performed. The investigation revealed that the center main bearing had failed. Fragments of the bearing had separated from the bearing backing and migrated into the space between the bearing and the crankshaft, causing the engine to lose power and seize.
