NTSB Narrative Summary Released at Completion of Accident

The pilot was making a pinnacle approach to the leeward side of a ridge. As he approached his touchdown point his airspeed was slowing to just above effective translational lift (ETL) when the aircraft was caught in a downdraft. He attempted to maneuver the aircraft but was unable to stop his decent or redirect his forward movement. The aircraft undershot the approach and struck the side of the ridge. The pilot said he had performed a high reconnaissance orbit and had monitored ATIS surface winds.

NTSB Probable Cause Narrative

the pilot's failure to abandon the pinnacle approach after encountering an excessive rate of descent.
