Aircraft Accident/Incident Report

Leadville, Colorado 80461
Sunday, July 6, 2003 12:35 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot took off and allowed the airplane to accelerate in ground effect to normal climb speed. When he initiated the climb, airspeed dropped 20 to 25 knots and the airplane settled back onto the runway. The airplane went off the end of the runway, struck a runway light and fence post, and traveled about 1,100 feet before coming to a halt. The empennage separated from the airplane when it collided with terrain. The pilot said the wind was from 160 to 200 degrees at 12 knots with gusts to 16 knots. At 1256, the recorded METAR (routine aviation weather report) at Leadville was as follows: Wind variable at 3 knots; visibility, 10 statute miles; few clouds, 11,000 feet; temperature, 21 degrees Celsius; dew point, minus 7 degrees Celsius; altimeter, 30.35 inches of mercury; peak wind, 180 degrees at 35 knots; rain began at 1235, and ended at 1246; sea level pressure, 1009.0 millibars.

NTSB Probable Cause Narrative

the pilot's inadequate compensation for wind conditions and his failure to attain adequate airspeed resulting in an inadvertent stall/mush. Contributing factors were the wind shear, runway light, fence post, and unsuitable terrain.
