Narrative:

The flight crew was to ferry medium large transport aircraft from den to dfw. The aircraft was parked in a remote location opposite gate xy about 100 ft in front of a blast fence. We started left engine and aborted the start due to a hung start. We restarted the engine and increased power to 65 percent N2 in order to stabilize engine as per company procedure. (Normal engine idle speed is 50-61 percent N2.) after starting right engine we taxied out with idle power. We were then notified by ground control we had blown 2 blast fence panels loose. I really don't understand how the fence panels were damaged since we were an adequate distance from the fence and idle power was used for taxi out.

Title: ACR DAMAGES BLAST FENCE ON START UP.

Narrative: THE FLC WAS TO FERRY MLG ACFT FROM DEN TO DFW. THE ACFT WAS PARKED IN A REMOTE LOCATION OPPOSITE GATE XY ABOUT 100 FT IN FRONT OF A BLAST FENCE. WE STARTED L ENG AND ABORTED THE START DUE TO A HUNG START. WE RESTARTED THE ENG AND INCREASED PWR TO 65 PERCENT N2 IN ORDER TO STABILIZE ENG AS PER COMPANY PROC. (NORMAL ENG IDLE SPEED IS 50-61 PERCENT N2.) AFTER STARTING R ENG WE TAXIED OUT WITH IDLE PWR. WE WERE THEN NOTIFIED BY GND CTL WE HAD BLOWN 2 BLAST FENCE PANELS LOOSE. I REALLY DON'T UNDERSTAND HOW THE FENCE PANELS WERE DAMAGED SINCE WE WERE AN ADEQUATE DISTANCE FROM THE FENCE AND IDLE PWR WAS USED FOR TAXI OUT.
