Probable cause

The pilot failed to maintain an adequate airspeed margin, resulting in a stall/mush and hard landing, and failed to maintain directional control and the left main landing gear separated when it struck a rock.

Analysis

The airplane bounced and veered off the left side of the runway. The pilot was on final and maintaining 85 knots as he initiated his flare. During the flare, he encountered wind shear and the airplane dropped from about 5 feet. The left main landing gear struck some large rocks and separated from the airplane. The pilot said a big upslope was near the runway. He estimated the winds to be from 010 degrees at 10 knots.
