Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Landing
First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Loss of control on ground/water
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
None

Cause areas

NTSB narrative

The balloon flight made a hard landing in 12-15 knots winds seriously injuring one of the two passengers aboard. The pilot delayed the flight and checked the weather several times before arriving at the launch site where the decision to launch was made. The pilot released two pibals at his residence located about 10 miles northeast of the launch site. The first pibal, released 1 hour and 10 minutes before the flight, headed towards 120-130 degrees at 12 knots. The second pibal, released 50 minutes before the flight, traveled in the same direction at a slower speed. During the drive to the launch site, the pilot noticed darkening skies and clouds to the northwest which he queried about when he called for an updated weather briefing. About 30 minutes after departure, the pilot noticed a breeze with a 190 degree change in wind direction and a decrease in speed. They proceeded westbound and began an ascent to 400 feet agl to clear power lines at which time the balloon was traveling about 15 knots towards the west. The pilot then descended to look for a landing area and stated that a gust pushed the balloon into trees during a landing approach. He heated the balloon, which was traveling about 12 knots, in order to get through the trees and attempted another landing. He told his passengers to prepare for a fast landing as they were traveling about 12-15 knots. The balloon came to rest 100 yards from the initial point of impact. Weather radar indicated an area of convective activity about 24 miles west of the accident site.

Probable cause

The inadequate weather evaluation by the pilot and high winds.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2002-06-17.
