A pilot diverted to Heber City due to lightning on route. On final, severe windshear and crosswind at 75 ft AGL caused the airplane to settle short of the runway. After a bounce and continued go-around, the airplane yawed off the runway, struck a fence post with a wing tip, and impacted terrain.

Flight Diversion and Weather

The pilot was in flight when light turbulence was encountered and lightning was observed on the intended route. To avoid the weather, the pilot diverted to Heber City.

Final Approach and Windshear

During the final approach to land, the airplane experienced severe windshear and a crosswind at approximately 75 feet above ground level (AGL). The pilot initiated a go-around, but the airplane continued to settle and touched down short of the runway, bouncing back into the air.

Go-Around and Runway Excursion

The pilot continued the go-around, but the airplane then yawed and drifted off the side of the runway. Subsequently, a wing tip struck a fence post, and the airplane impacted terrain, resulting in damage.
