Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the sightseeing flight stated that after departure, the balloon’s speed increased, and its direction of travel became different from preflight wind observations. During the flight, the pilot established radio contact with the pilot of another company balloon, and they decided to land at a park. The other company balloon, which was ahead of the accident balloon, landed in the park without incident. When the accident pilot attempted a similar landing, the balloon encountered wind shear, and he continued the flight and flew about 1.5 miles. The pilot found a long field sheltered by trees and terrain, in which to attempt a landing. The pilot briefed the passengers to hold on tight and to crouch down in the balloon’s basket for the landing. At 100 ft above ground level (agl), the balloon encountered wind shear and slowed to about 5 kts. At 50 ft agl, the approach was “normal,” but the balloon’s speed increased “very rapidly.” The pilot stated that he was committed to the landing due to the amount of heat he had vented from the balloon, which would not allow for a climb. The balloon touched down “fairly smoothly,” but its speed increased. The pilot pulled the rapid deflation line, but the balloon lifted off, so he reseated the deflation system to reduce a descent rate that ensued from about 20 ft agl. The pilot then pulled the rapid deflation line again when the balloon was about to touch down. During touchdown, the balloon tipped over onto its side and came to a stop after traveling about 120 ft. The balloon did not sustain damage. A passenger received serious injuries. The pilot stated there was no mechanical malfunction/failure of the balloon.
