Aircraft Accident/Incident Report
Jackson, Wyoming 83002
Friday, May 1, 1998 10:30 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot said he was 'breaking in a new engine' and he did not reduce power fast enough. The airplane landed long on runway 18, which was 6,299 x 150 feet, asphalt, porous friction course overlay. He said he realized he was not going to be able to stop the airplane on the runway that remained, and also realized he did not have sufficient speed to abort the landing. Heavy braking caused the left tire to blow out, and the airplane departed the end of the runway. The left main landing gear collapsed when the airplane traversed a large dip at the end of the runway, and the airplane slid to a halt approximately 100 feet beyond. Airport officials reported finding 1,400 feet of skid marks. A light and variable wind was reported at the time of the accident. The pilot attributed the accident to his error in judgment. His recommendation: 'Always land near the threshold, leaving as much runway as possible. Pretty basic.'
NTSB Probable Cause Narrative
the pilot's misjudgment of distance and speed, while approaching to land; his failure to attain a proper touchdown point for landing; and his failure to go around, while there was sufficient runway remaining. A related factor was the uneven terrain, which was encountered beyond the end of the runway.
