Narrative:
The pilot reported that the tower informed him the winds were from 250 degrees at 25 mph with gusts up to 30 mph. He aborted his first approach to runway 19R. On the second approach, he had "good rudder and aileron control at the 80 mph approach speed." At approximately 40 feet above ground level (agl), he encountered "a strong wind shear" and the airplane dropped to an altitude of 10 feet agl. The pilot added power and landed the airplane on the runway. At that time, a "very strong gust of wind" lifted the right wing and pushed the airplane towards the left side of the runway. The pilot attempted to regain control, however, he was not successful, and the airplane continued to the left "into a ground loop off of the runway." The nose landing gear collapsed, and the airplane came to rest nose down. The recorded winds at the airport near the time of the accident were from 260 degrees at 24 knots with gusts to 30 knots.

Probable Cause: The pilot's failure to maintain directional control during landing, resulting in a ground loop/swerve and collapse of the nose landing gear. A contributing factor was the gusty wind condition.
