Analysis

The pilot was attempting to land while a thunderstorm was within two miles of the airport. Strong turbulence was present during the approach but the pilot elected to continue the approach. A strong downdraft occurred when the aircraft was about 50 feet AGL. The aircraft struck the ground hard, short of the runway, breaking off the nose gear and right main gear. The aircraft then slid a short distance coming to rest to the right of runway 19.
