The pilot reported that, about 8 seconds into the takeoff roll in gusting wind conditions at high-density altitude, the airplane "suddenly and expectantly lifted off the runway in a steep angle of attack." He added that he immediately reduced power to idle to abort the initial climb, and the airplane "settled back onto the runway but landed hard." He further added that, during the landing roll, he lost directional control, and the airplane veered off the runway, coming to rest in the dirt alongside the runway. The fuselage, left wing, and aileron sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station, 10 nautical miles southeast of the accident airport, reported that, 5 minutes before the accident, the wind was from 150° at 16 knots, gusting to 25 knots. The pilot reported that he observed the wind from 300° at 8 knots, gusting to 15 knots. He reported that the takeoff was on runway 9. He further reported that the density altitude was 10,000 ft at the departure airport.
