THE DUAL STUDENT HAD PERFORMED SEVERAL MANEUVERS WITH THE LEFT ENGINE WINDMILLING AND DID NOT USE CARBURETOR HEAT WHEN CARBURETOR ICING CONDITIONS PREVAILED. UPON COMPLETING A MANEUVER AND RETURNING TO CRUISE FLIGHT, A POWER LOSS OCCURRED TO THE LEFT ENGINE. THE INSTRUCTOR TOOK OVER THE FLIGHT CONTROLS AND INITIATED A NORMAL DESCENT TOWARD A NEARBY AIRPORT. DURING THE DESCENT, HE SECURED THE LEFT ENGINE. AS THE AIRPLANE TURNED BASE TO FINAL APPROACH, THE RIGHT ENGINE'S CRANKSHAFT FRACTURED AND A FORCED LANDING HAD TO BE MADE TO UNSUITABLE TERRAIN APPROXIMATELY 1/4 MILE FROM THE RUNWAY. THE LEFT ENGINE WAS SUCCESSFULLY TEST RUN AFTER THE ACCIDENT. A TEARDOWN OF THE RIGHT ENGINE REVEALED THE FRACTURED CRANKSHAFT.
Probable Cause: THE LOSS OF POWER TO THE RIGHT ENGINE DUE TO A FRACTURED CRANKSHAFT WHILE THE LEFT ENGINE WAS SECURED. FACTORS WERE THE DUAL STUDENTS FAILURE TO USE CARBURETOR HEAT WHILE PERFORMING MANEUVERS AND THE UNSUITABLE TERRAIN.
