The pilot’s failure to maintain clearance from power lines while landing in a field.
Investigator assessment
Analysis narrative
The pilot reported that as he was attempting to land the hot air balloon in a field, the wind shifted and increased in speed. The pilot attempted to abort the landing but was unable to arrest the ballon’s descent. The balloon contacted power lines which resulted in an electrical arc and a shower of sparks. The arc severed 12 of the 16 flying wires, and the remaining flying wires failed in a manner consistent with overload. The basket separated from the envelope and came to rest on its side. The balloon sustained substantial damage to the flying wires, attachment hardware, and the basket support structure. The pilot reported that there were no preaccident mechanical malfunctions or failures with the balloon that would have precluded normal operation. The wind at the time of the accident was 350° at 9 knots.
