Narrative:
The pilot said that during takeoff roll on runway 21, the winds swung from the west becoming a right crosswind. "Holding the right wing down, I felt I would be better off airborne, so [I] lifted the airplane off. [The] wind pushed me left of [the] runway. I kept trying to force [the] airplane to fly, but didn't have enough airspeed." The pilot said that he turned slightly left toward lower ground in an attempt to gain airspeed. The pilot said, "From [an] estimated height of 20-30 feet, [the] stall warning horn began blaring, airplane mushed into [the ground] - no breakover from stall." An examination of the airplane revealed no anomalies. The reported winds, 20 minutes before the accident, were 290 degrees at 13 knots with gusts to 24 knots. The reported winds, 39 minutes after the accident, were 270 degrees at 17 knots with gusts to 22 knots.

Probable Cause: the pilot's failure to maintain aircraft control during initial takeoff climb. A contributing factor was the gusty crosswind.
