Narrative

WHILE OPERATING AND OCCUPYING R SEAT DURING A MAINT MOVE; WE HAD TO COME INTO A RAMP AREA IN FRONT OF OUR COMPANY HANGAR. A MARKED TXWY WAS BEING USED BY A CARGO COMPANY WITH MOTOR VEHICLES ALSO ON THE APRON. THE CARGO ACFT WAS PARKED ON TXWY. WE ELECTED TO TAXI TO THE NEXT ENTRANCE. WHILE ENTERING THIS AREA; B757 WAS OFF ON OUR R. I; IN THE R SEAT; VERIFIED CLRNC WHILE THE L SEATER CONTINUED (ON HIS L WAS A HANGAR). AFTER MOVING IN TO THE RAMP; WE OBSERVED A MARSHALLER. I TURNED MY ATTN TO THE B757 ON MY R TO ASSURE CLRNC. WHEN I FELT WE WERE CLR; I TOLD MY L SEATER TO TURN R; AFTER 3 CALLOUTS TO DO THIS TURN; I LOOKED UP TO SEE AN AERO LADDER STAND. I TOLD THE L SEATER; 'WATCH FOR THE STAND;' WHICH WAS OFF TO OUR L STILL IN FRONT OF US. I AGAIN LOOKED OUT MY WINDOW (R SIDE) AND AGAIN CALLED TO TURN. I FELT THE PUMPING OF THE BRAKES; BUT STILL NO TURN; STILL INSTRUCTED THE TAXIING 'DRIVER' TO TURN; WHICH FINALLY HE STARTED. AFTER A TAXI AROUND A DC8 AND AWAITING A B727 CARGO ACFT PARKED IN OUR RAMP AREA TO LEAVE; WE MADE OUR 3 L TURNS TO OUR PARKING. UPON LEAVING OUR ACFT; WAS INFORMED THAT THE L WING CONTACTED THE AERO STAIRS; BREAKING A STATIC WICK; LENS STROBE LIGHT. I CHKED THE DAMAGE; NONE STRUCTURAL. THE AERO STAND RUBBER BUMPER CAUGHT THE AREA DESCRIBED. REPAIRS: LENS; LIGHT ASSEMBLY; STATIC WICK WERE DONE IN 30 MINS. FACTORS: CONGESTED AREA; NOT TURNING WHEN I ADVISED; POOR MARSHALLER FACTORS; AND PLACEMENT IN AREA NOT ALLOWED FOR STAND.
