The NTSB's narrative final · quoted from the NTSB record

The balloon caught fire after landing during the Battle Creek Field of Flight Hot Air Balloon Festival. The pilot stated that after approximately one hour in the air, the balloon landed safely in a yard. When the pilot looked up inside the top of the balloon envelope, the "parachute top did not reseat." He attempted to reseat the top by using a "blast of heat" from the burners but it did not work. The pilot "knew the balloon would quickly sink down on top of the basket" so he turned the burners to their horizontal position and prepared to push the envelope fabric away. When the balloon envelope began to descend towards the ground the pilot reported that "we suddenly had a fire in the basket." Both the pilot and passenger were able to exit the basket. The pilot "determined the fire was coming from the burners" so he returned to the basket and turned off the fuel tanks. The fire was subsequently extinguished by the passenger and bystanders. An examination of the balloon after the accident revealed the fuel valve for the whisper burners was in the "on" position.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CHI07CA189.
