Probable cause

The pilot allowed the aircraft to inadvertently touch down, he delayed making a go-around, and he did not maintain sufficient speed to continue the go-around. Contributing factors were: the pilot's selection of unsuitable terrain, high vegetation in the selected landing area, a downdraft, and rough terrain in the dry river bed.

Analysis

The plt was on a flt to the Nebesna Glacier area to go hunting. He found what looked like a choice site to land from where he planned to hike. His 1st apch to land was long, so he made a go-around. His 2nd apch was also long, but this time, the acft touched down & the wheels caught some low shrubs, slowing the acft. The plt stated he 'added full power for go-around, struggled into the air with full flaps, and turned toward lower terrain' which was down wind. He said the acft encountered a downdraft & was 'pushed' into a dry river bed. He stated that he made a controlled landing about 1/2 mi from the intended landing area, but the terrain was too rough & the landing gear broke off.
