Los Alamos Airport
Aircraft Accident/Incident Report

Los Alamos, New Mexico 87544
Friday, June 23, 2000 12:10 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was completing a flight review and performing a full stop landing at the airport where the aircraft was based. The airport altitude was 7,171 feet msl, the temperature was 72 degrees Fahrenheit, and the density altitude was computed to be 9,300 feet. The wind was a 4 knot tailwind component. Thus, the ground speed was calculated to be 31 knots above the indicated airspeed and the pilot said he landed 'long and fast.' The aircraft went off the end of the runway during landing roll and struck the blast fence. The collision destroyed the aircraft; however, the private pilot and flight instructor check pilot were not injured.

NTSB Probable Cause Narrative

The pilot's misjudgment of distance/speed resulting in an overrun and subsequent collision with a blast fence. Contributing factors were high density altitude, a tailwind, and the blast fence.
