The airplane collided with high vegetation when the pilot made an off airport forced landing following a loss of engine power. The local aerial application flight departed a private strip. The pilot reported that a heavy vibration developed in the engine, and he shut it down. He tried to return to a nearby dirt strip, but had to land in a hay field. On the landing roll, the airplane encountered tall vegetation, which damaged the wings and landing gear attachment points. A Federal Aviation Administration inspector examined the airplane, and found a fractured bolt on the propeller. Metallurgical examination of the bolt indicated that the part failed in fatigue at a region of increased stress (stress concentration), though the part overall was not highly stressed (small overstress region).
Probable Cause: a fatigue failure of a propeller bolt.
