Probable cause

The pilot's failure to compensate for the loss of lift due to ice accumulation on the wings, his failure to control the rate of descent, and poor inflight decision making. Contributing to the accident was the pilot's fatigue.

Analysis

The pilot and passenger stated that ice had accumulated on the airplane during the flight. The pilot stated that he was fatigued from the long flight. The passenger estimated the ice was about 1 to 2 inches thick and that on the base to final turn the airplane banked to approximately 30 degrees. The rate of descent increased and the pilot was unable to arrest the descent before the airplane landed hard short of the runway. The airplane struck the approach lights before coming to rest.
