NTSB narrative
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.
Probable cause
The whisper burner's fuel valve opening for undetermined reasons, which resulted in a fire after landing. A factor in the accident was the balloon envelope's parachute top not reseating.

- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2007-07-03.
