Narrative:
The pilot of the experimental amateur-built airplane stated that he was on final approach when the airplane 'abruptly' turned right 45°, and the flight controls no longer felt normal. The pilot said it was a challenge to maneuver the airplane and, as he attempted to avoid trees, the airplane stalled and impacted the ground. A postaccident examination of the airplane and its two-stroke engine revealed that the belt that connected the engine output sprocket to the propeller drive sprocket had broken. The belt had not been manufactured for use in aircraft. Examination of the edges of the belt revealed that it appeared rubbed with exposed core strands in several areas consistent with lateral travel or tracking and that the belt ultimately broke due to tensile overload failure.

Probable Cause: Failure of the engine/propeller drive belt.
