Probable cause

The pilot's improper inflight planning/preparation, and his failure to attain the proper touchdown point. Contributing to the accident was the downdraft.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

Both pilots reported that they encountered a downdraft during the final approach which caused the airplane to develop a higher than desired sink rate. The application of power failed to arrest the sink rate before the airplane touched down approximately one foot short of the runway. The airplane came to a stop about 1,000 feet down the runway, with all three landing gear collapsed. The pilot said that he had encountered light to moderate turbulence during the approach, and he was 'shooting for the end of the runway'.
