While in cruise flight, the airplane's left engine lost total power. Due to the damage incurred by the engine during its failure, the propeller could not be feathered and the airplane could not sustain flight. The pilot made an emergency landing in a field and during the roll out the left main gear and nose gear collapsed. Post accident examination of the failed engine revealed the number four cylinder and piston were gone from the case. The left case and fasteners were examined at the Safety Board's Materials Laboratory. The examination revealed fatigue cracking in the engine case, through bolts and studs. Three of the six studs around the number four cylinder were not recovered. The initial failure was not determined.
