Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

SHORTLY AFTER LIFTING OFF, THE PILOT LIGHT ON THE BALLOON'S PROPANE BURNER EXTINGUISHED FOR UNDETERMINED REASONS, AND ATTEMPTS TO RELIGHT IT WERE UNSUCCESSFUL. BECAUSE THE BALLOON WAS DESCENDING NEAR POWERLINES, THE PILOT 'VENTED' IN ORDER TO RAPIDLY LOSE ALTITUDE. THE BALLOON TOUCHED DOWN ON A HIGHWAY, BOUNCED BACK UP, AND THE ENVELOPE CONTACTED POWERLINES, BURNING SEVERAL ENVELOPE PANELS.
NTSB Probable Cause
A TOTAL FAILURE OF THE BALLOON'S HEATER SYSTEM (PILOT LIGHT) FOR UNDETERMINED REASONS. A FACTOR WAS UNSUITABLE TERRAIN ON WHICH TO MAKE A FORCED LANDING.
Full Narrative
On July 1, 1994, approximately 0730 mountain daylight time, N748CB, a Cameron Balloons V-77, was substantially damaged when it collided with powerlines in Littleton, Colorado. The private pilot was not injured. Visual meteorological conditions prevailed. The following is based on the pilot/operator report. Shortly after lifting off, the pilot light on the propane burner extinguished for undetermined reasons, and attempts to relight it were unsuccessful. Because the balloon was descending near powerlines, the pilot "vented" in order to rapidly lose altitude. The balloon touched down on a highway, bounced back up, and the envelope contacted powerlines about 20 feet above the basket. Several envelope panels were damaged by electrical arcing and there was a small grass fire.
