NTSB Narrative Summary Released at Completion of Accident

According to the pilot, after several attempts to extend the landing gear, he manually extended the landing gear. After a "slow" landing and a "brief" rollout, the landing gear collapsed. The airplane settled onto the runway, slid approximately 200 feet and came to a stop on the runway centerline. Within a few moments a fire ensued, destroying the airplane. A witness stated that the airplane landed on its tires and then rolled several feet before the landing gear collapsed. An examination of the airplane revealed no anomalies.

NTSB Probable Cause Narrative

the failure of the landing gear extension system for undetermined reasons.
