Aircraft Accident/Incident Report
Nenana, Alaska 99760

NTSB Narrative Summary Released at Completion of Accident
The private pilot was conducting a personal local flight under Title 14, CFR Part 91. A witness said he saw the accident airplane flying level above the trees, when it abruptly started a steep, near vertical, climb. At the top of the climb, the witness said the airplane descended in a steep spiral and impacted the ground. The airplane impacted in a near vertical, nose low attitude. The right wing was found standing on its leading edge, with its top wrapped counter-clockwise around a small group of willows. Both blades of the two-bladed propeller had extreme bending and torsional twisting, chord-wise scratching, and areas sanded clean of paint. The engine exhaust manifold had plastic folding. The accident pilot/owner was a certified aircraft mechanic, who reportedly maintained the accident airplane. No airframe or engine logbooks were discovered for examination. No preimpact mechanical problems were discovered during the investigation. Federal Aviation Regulation Part 91.303, defines any abrupt change in an aircraft's attitude, an abnormal attitude, or abnormal acceleration not necessary for normal flight, as aerobatic flight.
NTSB Probable Cause Narrative
The pilot's failure to maintain minimum airspeed to avoid a stall while maneuvering, which resulted in a loss of control, a stall/spin, and impact with terrain. Factors associated with the accident were an aerobatic maneuver, and a stall/spin.
