ACR ACFT CONTACTS JETWAY DUE IMPROPER MARSHALLING; DAMAGE RESULTS.

Narrative

WHILE TAXIING INTO THE GATE AREA AND FOLLOWING THE DIRECTIONS OF A GND MARSHALLER; OUR #2 ENG STRUCK THE JETWAY BRIDGE. WE WERE TAXIING WITH THE #1 AND #4 ENGS SHUT DOWN. THE ACFT LOST MOMENTUM AND CAME TO A STOP SHORT OF WHERE THE MARSHALLER WANTED US. WE WERE SIGNALED TO COME FURTHER FORWARD AND THE CAPT APPLIED PWR TO THE #2 AND #3 ENGS. AS THE ACFT STARTED TO ROLL AGAIN; IT SUDDENLY JERKED TO A STOP. THE CAPT SHUT DOWN THE ENGS AND SET THE PARKING BRAKE. IT WAS THEN WE REALIZED THAT WE HAD HIT THE JETWAY. THERE WERE NO INJURIES; BUT THE TOP OF THE #2 ENG INLET WAS CRUSHED INWARD. WE WERE LATER INFORMED THAT THE JETWAY WAS NOT IN THE CORRECT POS. AN AIRBUS A320 HAD DEPARTED THE GATE JUST PRIOR TO OUR ARR AND THE JETWAY WAS EXTENDED FOR THE A320. NONE OF THE RAMP PERSONNEL OR THE JETWAY OPERATOR NOTICED THIS. THE MARSHALLER HAD BEEN ONLY WATCHING THE NOSE WHEEL IN REF TO THE PAINTED LINE ON THE RAMP FOR THE RJ. ALSO CONTRIBUTING WAS THE FACT THAT THE L WING WALKER ABANDONED HIS POS EARLY SO HE COULD CHOCK THE L MAIN TIRES. HE COULD HAVE PREVENTED THIS OCCURRENCE IF HE WOULD HAVE STAYED WHERE HE WAS SUPPOSED TO BE.
