Narrative:
Shortly after takeoff, at 300 feet above ground level, the engine "revved excessively and power was lost to the propeller." The pilot performed an off airport forced landing. During the forced landing, the airplane impacted terrain and sustained substantial damage to the forward fuselage. Examination of the airplane revealed that both engine-to-propeller drive belts failed, which led to the reported engine overspeed and lack of propeller drive. A representative of the manufacturer stated that the belt failure during the accident was caused by loose belts or a lack of proper tension on the belts and that the belt tension should have been checked during a preflight inspection.

Probable Cause: A loss of engine thrust during takeoff due to the failure of the engine-to-propeller drive belts as a result of improper belt tension. Contributing to the accident was the non-certificated pilot's improper preflight inspection.
