Primary finding
Probable cause
The pilot’s failure to maintain clearance from power lines during landing.
Investigator assessment
Analysis narrative
During the slow descent from about 300 feet, the hot air balloon hit power lines. The pilot stated that, as the balloon descended, the wind shifted, and the forward speed of the balloon was reduced. Instead of continuing past the power lines, the gondola of the balloon descended between the power lines, and the envelope of the balloon became entangled in the wires. A postimpact fire ensued, resulting in substantial damage to the envelope and gondola. The pilot stated that there were no mechanical anomalies with the balloon prior to the accident.
