Aircraft Accident/Incident Report

Biddle, Montana 59314
Tuesady, July 8, 1997 8:15 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot took off downhill and to the northeast with a left quartering tail wind from the southwest of approximately 5-8 knots. Shortly thereafter the aircraft crossed over a bluff where the terrain dropped off, and passed over an area populated with deciduous trees. The aircraft began to settle and the pilot executed a left turn toward the west. Just after the aircraft cleared the tree line, it impacted the ground left wing and nose low, coming to rest 49 feet beyond the initial ground impact point. A post crash fire developed and the pilot and his wife exited with minor injuries.

NTSB Probable Cause Narrative

The pilot-in-command's failure to maintain adequate airspeed which resulted in a stall/mush. A factor contributing to the accident was the tailwind condition on takeoff.
