Aircraft Accident/Incident Report

Jackson Hole, Wyoming 83002
Sunday, August 8, 2004 16:40 MDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he had attempted to land on runway 19 but had performed a go-around because of windshear approximately 15 to 20 feet agl. During the second attempt to land, he increased his airspeed to compensate for the wind. The pilot reported that during the landing flare "the bottom dropped out." He increased power to go around but the airplane continued to sink. The airplane drifted to the left and subsequently struck a runway light causing substantial damage. The Automated Weather Observation System reported the winds at 1640 as 210 degrees at 9 knots. The pilot estimated that the winds at the time of the accident were 250 degrees at 10 to 15 knots.

NTSB Probable Cause Narrative

the pilot's failure to maintain aircraft control resulting in a stall/mush. Contributing factors include the windshear, the crosswind and the runway light.
