NTSB Narrative Summary Released at Completion of Accident

The balloon touched down hard at the conclusion of a sightseeing flight seriously injuring one of the eight fare-paying passengers. The pilot indicated that upon entering a wider area of the Napa Valley the winds aloft should have slowed, but they did not. Therefore, he decided to land as soon as possible, having the belief that the wind speed might increase if he continued the flight. During the descent to an open field, the balloon drifted over a row of estimated 30- to 40-foot-tall trees, and the wind speed suddenly increased to between 10 and 12 miles per hour. The pilot advised the passengers to prepare for a possible hard touchdown, and during the final seconds of the flight, he used both burners at maximum power to slow the descent rate. However, a windshear was encountered, and the balloon abruptly descended.

NTSB Probable Cause Narrative

The pilot's encounter with wind shear during landing, which resulted in a hard touchdown.
