Aircraft Accident/Incident Report

Longmont, Colorado 80501
Sunday, May 17, 1998 8:30 MDT

NTSB Narrative Summary Released at Completion of Accident

During the landing approach, the winds were from the south at 5 to 7 knots. At 30 to 40 feet above the ground, the pilot encountered wind shear out of the east at 30 to 35 knots, and the intended landing was aborted. The pilot climbed to 150 agl and set up for a high wind landing. Upon touchdown, the pilot's foot was caught between the wicker siding and the solid floor of the basket, and the pilot's ankle was broken. According to the pilot, the accident would not have occurred had he not improperly placed his foot between the wicket basket and the floor plate of the balloon at the time the balloon impacted the ground.

NTSB Probable Cause Narrative

The pilot's failure to properly position his foot for a high wind landing. Factors were high winds and windshear.
