Analysis

A local hunting guide crashed his airplane in a remote mountain pass in central Alaska. Another guide who overflew the crash site shortly after the accident saw the airplane burning, but was unable to land due to strong winds, severe turbulence and strong downdrafts. The private pilot-in-command of the crashed airplane was killed and the airplane was destroyed. Earlier conversations between the PIC and a state trooper revealed that the former liked to fly low to the ground during hunting season in order to keep from disturbing sheep on the mountain sides. Physical evidence at the accd site indicated that a wingtip initially struck the ground followed by the acft cartwheeling.
