Analysis

A forced landing was attempted following a complete eng failure. The plt overshot the intended touchdown pt and pulled the acft off the grnd in an attempt to clear a busy hwy. however, the acft struck wires located next to the road. Evidence indicated that the eng failure was caused by the fatigue failure of the 4 bolts that attached the cluster gear to the camshaft. One of the bolt heads was jammed between the cluster gear and the crankshaft gear, which seized the eng. The fatigue failures appeared to be the result of improper torque application during the previous installation.
