The pilot's encounter with a wind shear at low altitude, which resulted in a loss of control and a stall/spin. Factors in the accident were the high density altitude and the pilot's lack of experience and training in high density altitude operations. The pilot's decision to takeoff downwind, while reasonable given the nature of the obstacles and terrain on the other runways, set up a situation where decreased safety margins existed and is considered a factor.

THE FAILURE OF THE PILOT IN COMMAND TO MAINTAIN DIRECTION CONTROL. FACTORS IN THE ACCIDENT WERE THE PILOT IN COMMAND'S PREMATURE ROTATION DURING THE TAKEOFF AND THE FAILURE TO TAKE THE NECESSARY REMEDIAL ACTION.
