## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) WHILE IN CRUISE, TRACKING SOUTH TO NORTH, APPROXIMATELLY 2 NM NORTH OF PROSSER AIRPORT AT AN ESTIMATED ALTITUDE OF 400 TO 500 FEET, THE PILOT SWITCHED PROPANE FUEL TANKS.  THE NEXT DEMAND FOR FLAME (POWER) FROM THE NEW TANK PROVIDED INADEQUATE FLAME DUE TO AN APPARENT TANK LOW PRESSURE SITUATION.  DURING THIS TIME, THE BALLOON WAS DESCENDING, AND THE TIME REQUIRED TO SWITCH TO A TANK WITH ADEQUATE PRESSURE, (THE BALLOON AS CARRYING 4 PROPANE FUEL TANKS) THE BALLOON SETTLED, AND A CORNER OF THE BASKET HOOKED A POWERLINE.  AT THE SAME TIME AS THE CONTACT WITH THE POWERLINE, FLAME WAS RESTORED AND THE BALLOON BEGAN TO RISE.  UPON THE RELEASE OF THE POWERLINE DURING THE RISE OF THE BALLOON, THE POWERLINE CAME INTO CONTACT WITH ANOTHER POWERLINE CAUSING AN ARC, RESULTING IN A BLOWN POWERLINE FUSE.  NO DAMAGE OR INJURIES REPORTED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
