Primary finding
Probable cause
The airplane’s encounter with unexpected wind shear during final approach, which resulted in a hard landing short of the runway.
Investigator assessment
Analysis narrative
The pilot reported that he was flying the RNAV (GPS) approach to runway 24 and experienced turbulence about 1,500 ft mean sea level (msl), which was about 700 ft above ground level (agl). He continued the approach with an airspeed between 95 and 100 kts. He stated that about 50 ft agl and short of the runway, the airplane encountered wind shear that violently forced the airplane to the ground. The airplane impacted the ground in a wings level attitude and continued onto the runway. The left main landing gear separated, the airplane veered off the left side of the runway, then came to rest in the grass facing 180° from the direction of travel. Postaccident photos of the airplane revealed substantial damage to the right wing. The pilot reported no preimpact mechanical malfunctions or failures that would have precluded normal operation. The pilot stated to the responding fire department that there was a 30 kt crosswind on final approach. The recorded wind data around the time of the accident showed the wind was from 250° to 260° and 7 to 11 kts.
