The commercial pilot and three passengers were making a personal cross-country flight in the airplane. After a refueling stop, the airplane taxied to the runway and departed. Security video and flight data showed that the airplane had just departed the airport and was about 280 ft above the ground when it stalled and spun to the left, impacting the ground in a nose-down attitude. Post-accident examination of the engine and airframe revealed no evidence of a mechanical anomaly or failure that would have precluded normal operation of the airplane. The recorded weather at the airport at the time of the accident included a right-quartering headwind at 8 knots gusting to 17 knots. The flight data revealed that the airplane slowed to a groundspeed of 48 knots just before the stall occurred, which was below the airplane's published power-on stall speed of 53 knots; however, the gusting wind conditions likely resulted in a further decease of the airplane's airspeed and increase of its critical angle-of-attack.
Probable Cause: The pilot's failure to maintain adequate airspeed during initial climb in gusty wind conditions, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall/spin.
