Narrative:
While operating and occupying right seat during a maintenance move, we had to come into a ramp area in front of our company hangar. A marked taxiway was being used by a cargo company with motor vehicles also on the apron. The cargo aircraft was parked on taxiway. We elected to taxi to the next entrance. While entering this area, B757 was off on our right. I, in the right seat, verified clearance while the left seater continued (on his left was a hangar). After moving in to the ramp, we observed a marshaller. I turned my attention to the B757 on my right to assure clearance. When I felt we were clear, I told my left seater to turn right, after 3 callouts to do this turn, I looked up to see an aeronautical ladder stand. I told the left seater, 'watch for the stand,' which was off to our left still in front of us. I again looked out my window (right 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 aircraft parked in our ramp area to leave, we made our 3 left turns to our parking. Upon leaving our aircraft, was informed that the left wing contacted the aeronautical stairs, breaking a static wick, lens strobe light. I checked the damage, none structural. The aeronautical 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.

Title: A B757-200 HAS ITS L WINGTIP DAMAGED DURING A MAINT NIGHT TAXI OP TO THE HANGAR.
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.
