TAXIING LGT STRIKES PARKED LGT.

Narrative

AFTER A 30 MIN TAXI FROM THE TERMINAL; I WAS PARKED IN THE RUN UP BLOCK FOR RWY 18 IN THE #1 POS FOR TKOF WITH PARKING BRAKES SET. ANOTHER ACR LGT MOVING INTO THE #2 POS STRUCK OUR RIGHT WING WITH HIS LEFT WING. HE INFORMED THE DCA TWR. WE QUICKLY CONFIRMED THERE WAS NO FUEL LEAKING OR FLAP DAMAGE TO OUR ACFT; HOWEVER THE WINGS WERE IN CONTACT. WE CALLED OUR OPS FOR MECHS TO COME TO GIVE A VISUAL CHK. IT TOOK ABOUT 15 MINS FOR THEM TO ARRIVE IN A PORT AUTHORITY VAN. THEY CONFIRMED THAT OTHER LGT WING WAS AFT OF OURS AND WE WOULD HAVE TO MOVE FIRST. WE INFORM THE TWR AND THEY CLRED TXWY J SO WE COULD BACK TAXI. WE WERE CLRED TO TAXI; HOWEVER I FIRST HAD TO PULL FORWARD COMPLETELY OVER THE RWY HOLD LINE BEFORE TURNING RIGHT (S) ON J; AND THERE WAS AN ACFT IN POS FOR POS FOR TKOF AND ONE ON A SHORT FINAL. I REFUSED TO MOVE UNTIL BOTH ACFT WERE CLR; BUT WAS UNABLE TO COMMUNICATE WITH TWR BECAUSE THEY WERE SO BUSY. 2 THINGS CONTRIBUTED TO THIS INCIDENT: FIRST; BECAUSE OF GRIDLOCK ON THE ARPT; GND CTL WAS ASKING FOR MINIMUM TAXI INTERVAL. THE OTHER THING IS THE RIDICULOUS RITUAL AT DCA RUNUP BLOCK OF MANEUVERING IN TURN EACH TIME AN ACFT VACATES FOR TKOF BY MAKING A 120 DEG TURN AND MOVING CLOSE TO THE NEXT ACFT USUALLY OVERLAPPING WINGTIPS.
