NTSB Narrative Summary Released at Completion of Accident

The 848 hour pilot/owner of the kit built Riddell/Lancair IV-P was on a 3-4 mile final to runway 30 when the engine lost power. Witnesses reported observing the aircraft approximately 200-500 feet above ground when it executed a steep right turn; pitched nose up and then rolled left ultimately impacting the ground at a steep angle and exploding. Post-crash examination revealed no evidence of mechanical malfunction.

NTSB Probable Cause Narrative

The loss of power for undetermined reason(s) and the pilot's failure to maintain the aircraft's flying speed above the power off stall speed in the landing configuration.
