The pilot reported that while en route at 9,500 feet msl, the engine quit and attempts to restart it were unsuccessful. The pilot picked out a field and maneuvered the airplane to a 'low key' position abeam his landing point at 1,200 feet agl. He reported extending the landing gear after low key, but when he was at the 90 degree position, he noticed a tower in the field. To avoid the tower, the pilot withheld flap extension and 'zoomed' the aircraft to clear the guy wires supporting the tower. The pilot reported that the airplane stalled at approximately 20 feet above ground level at 65 miles per hour. The engine teardown and inspection revealed broken camshaft gear drive attachment bolts. A metallurgical examination indicated that the failure was due to fatigue. The metallurgist reported the evidence of fatigue failure was exhibited by the beach marks and ratchet marks which suggested that the bolts were under torqued, thus leading to fatigue failure.
Probable Cause: the pilot selected a field with unsuitable terrain and stalled the airplane. Additional factors were the tower in the field, and engine failure due to the improper torque applied to camshaft bolts by other maintenance personnel.
