Probable cause

the pilot's inadvertent weather encounter with wind shear, and the resulting inability to maintain the proper landing descent rate, which resulted in a hard landing. A factor was the high wind weather condition.

Analysis

The pilot received weather information from several sources beginning at 0300 that morning. Additionally, he obtained wind data from a remote sensor northwest of Rio Rancho and from another near Sandia Peak. The forecast he received indicated winds from 200 degrees at 8 knots till 1000 and then changing to 250 degrees at 13 knots gusting to 22 knots. He launched a pibal to check the current wind speed at the launch site and he determined it was "favorable." He launched with eight passengers on board and when he first checked his airspeed it was 4 knots. After climbing over a mesa, he noted that his airspeed had increased to 8 knots and was increasing. At that point of the flight, there were no favorable landing sites. He found a suitable landing site of open desert and briefed the passengers on high wind landing procedures. The pilot said that as the balloon descended, it passed through a wind shear zone with surface winds up to 30 knots. The winds on the lower half of the balloon created a false heavy and the pilot could not slow the excessive descent. After impact, the balloon skidded approximately 100 yards before its envelope could be deflated and the balloon stopped. During the landing, one passenger broke an ankle.

Factual narrative

On June 13, 2001, at approximately 0735 mountain daylight time, a Cameron Balloons N-210 balloon, N7507V, received minor damage during a hard, high wind landing near Rio Rancho, New Mexico. The commercial pilot and two passengers were not injured; however, one passenger was seriously injured, and five passengers received minor injuries. The balloon was being operated by World Balloon LLC, Albuquerque, New Mexico, under Title 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident. The local flight originated from Rio Rancho, New Mexico, approximately 45 minutes before the accident. No flight plan was filed.

The pilot said he received weather briefings from a variety of sources beginning at 0300 that morning. His first weather briefing was from a website on his home computer. A Flight Service Station briefing was obtained by two other pilots (who were launching with him), and he was briefed by them. Additionally, he obtained wind data from a remote sensor northwest of Rio Rancho and from another near Sandia Peak. The forecast he received indicated that winds would be from 200 degrees at 8 knots till 1000, and then changing to 250 degrees at 13 knots gusting to 22 after 1000. He launched a pibal (a small helium filed balloon) to check the current wind speed at the launch site and he determined it was "favorable."

The pilot launched with eight passengers on board, and after liftoff noted on his global positioning system that his airspeed was 4 knots. After climbing over a mesa, his airspeed increased to 8 knots. He said that 20 minutes into the flight, his airspeed was between 16 to 20 knots. At that point, there was not a suitable landing area due to a housing area and electrical transmission lines. He attempted to descend behind a hill to obtain shelter from the wind, but the wind shear became too severe for balloon operations. He found a suitable landing site of open desert and briefed the passengers on correct high wind landing procedures. During descent, the balloon's speed increased to 30 knots and directional control became difficult. During the final descent, he fired both burners all the way to the ground. Despite the firing of both burners, the balloons glide path deteriorated to 45 degrees. The balloon skidded approximately 100 yards before the envelope could be deflated and the balloon stopped. During the landing, one passenger broke an ankle.
