Aircraft Accident/Incident Report

Gunnison, Colorado 81230
Friday, July 5, 1996 7:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The balloon pilot said that when he took off, the wind was calm. After about 15 minutes of flying at 1,000 feet agl, he noticed other balloons at lower altitudes traveling at higher ground speeds. The pilot descended to 200 to 300 feet agl and estimated the wind at that altitude to be in excess of 30 knots. After flying at this altitude for about 10 minutes, the pilot decided to land in an open field. During the high wind landing, one of the two passengers sustained a serious injury. The pilot said that about 15 minutes after the landing, the winds were again calm.

NTSB Probable Cause Narrative

The pilot's improper planning/decision. The weather condition (sudden high wind) was a related factor.
