Aviation Accident Summary WPR19LA104

Yountville, CA, USA

Aircraft #1

N6954Y

Cameron A-400

Analysis

During cruise flight, the balloon encountered a sudden downdraft. The pilot arrested the descent to level flight, but not in time to prevent the bottom of the basket from contacting nearby power lines. The pilot subsequently landed the balloon without further incident. One passenger sustained serious injuries. The pilot reported that there were no preaccident mechanical failures or malfunctions with the balloon that would have precluded normal operation.

Factual Information

On April 1, 2019, about 0757 Pacific daylight time, a Cameron Balloons US, A-400 hot air balloon, N6954YA, was not damaged when it was involved in an accident near Napa, California. The pilot and 18 passengers were not injured, one passenger sustained serious injuries and two passengers sustained minor injuries. The balloon was operated as a Title 14 Code of Federal Regulations Part 91 sightseeing flight. The pilot reported that, about 10 minutes into the flight, and about 500 ft, the wind changed direction and the balloon entered a downdraft. The pilot added heat to compensate for the descent and level flight was established. The balloon’s basket subsequently contacted a power line. After the pilot attained a slow ascent, the power line released from the basket, and the pilot immediately landed the balloon in a field without further incident. The pilot reported that there were no preaccident mechanical failures or malfunctions with the balloon that would have precluded normal operation.

Probable Cause and Findings

The pilot’s inability to maintain obstacle clearance after the balloon’s encounter with a downdraft, which resulted in a collision with power lines.
