Aircraft Accident/Incident Report

Woodstock, Georgia 30214
Saturday, July 3, 1999 21:29 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that the balloon was carefully examined and assembled prior to flight and no mechanical problems were found. After 45 minutes of standing and ascending tether operations, the pilot's son noticed fire dripping from the fitting that connects the main fuel line to the burner assembly. After unsuccessfully trying to extinguish the fire, the pilot pushed his son from the balloon at ground level. The balloon then ascended rapidly to the extent of the 25 foot tethers. At that point, the pilot elected to jump from the balloon. After 15 to 20 minutes, the fire burned through the tether ropes releasing the balloon, which drifted unmanned for approximately one hour before descending and colliding with a single family dwelling. The balloon was destroyed. Examination of the fuel line fitting revealed a loose connection between the two threaded ends. According to the manufacturer of the fuel hose, it is produced for use in air conditioning applications and should never be used with LP gas.

NTSB Probable Cause Narrative

A loose connection between the fuel line fitting and the burner assembly which resulted in a fire.
