Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

Witnesses reported seeing the airplane stop on the runway and the engine stop producing power during the takeoff. The private pilot/owner subsequently deplaned and hand propped the engine, which was not equipped with an electric starter, to restart it. The pilot continued the takeoff in tailwind conditions on the 2,500 feet of remaining up-sloping runway. The airplane lifted off the runway in a near-vertical climb and traveled about 2,900 feet before it rolled left and descended vertically to the ground. Flight control continuity was established during postaccident examinations; however, the engine could not be examined due to fire and impact damage. The airplane’s previous owner described the airplane’s design as inherently unstable and stated that higher airspeeds were required to maintain stability in all phases of flight and that the wing would dip very quickly in a stall.

NTSB Probable Cause Narrative

The pilot's failure to maintain airspeed during a near-vertical climb after takeoff, which resulted in an aerodynamic stall and subsequent collision with terrain.
