THE PIC OF A CL65 PERFORMS A R TURNOUT FROM THE GATE WITH ONLY #2 ENG RUNNING AND DAMAGES THE JETWAY BRIDGE WITH JETBLAST AT BUF; NY.

Narrative

AFTER THE COMPLETION OF THE CLOSEOUT CHKLIST; THE CAPT TOLD ME TO PLAN ON STARTING 1 ENG FOR A SINGLE ENG TAXI; IN ORDER TO SAVE FUEL. AFTER RECEIVING THE SIGNAL FROM THE MARSHALL THAT IT WAS ALL CLR TO START; THE CAPT COMMANDED THE START. I STARTED THE R ENG AFTER I COMPLETED THE BEFORE START CHKLIST. THEN; ALONG WITH CAPT; WE COMPLETED THE AFTER START CHKLIST. I EXPLAINED TO THE CAPT THAT THE R ENG WAS STARTED. HE ACKNOWLEDGED AND ADVISED ME TO STILL PLAN ON A SINGLE ENG TAXI. THE MARSHALL CLRED US TO TAXI AWAY FROM THE GATE ON THE RAMP. CAPT CALLED 'CLRED L;' THEN ASKED; 'CLRED R?' I TURNED MY HEAD TO THE R AND VISUALLY CONFIRMED THAT THE ACFT WAS CLR OF ALL OBSTACLES AND PERSONNEL AND CALLED OUT 'CLRED R.' THROUGHOUT THE ENTIRE TURN; I KEPT MY EYES AND ATTN OUTSIDE OF THE ACFT IN ORDER TO BE IN A CONTINUOUS POS TO KEEP THE ACFT CLRED R. AFTER THE COMPLETION OF THE TURN TO THE R; I CONTACTED GND AND RECEIVED A CLRNC TO TAXI TO RWY 23. DURING THE ENTIRE TAXI FROM THE GATE TO THE RWY WE WERE NEVER GIVEN ANY SIGNALS; NOR WAS IT EVER COMMUNICATED TO THE CREW THAT THERE HAD BEEN A SIT. THIS SIT COULD HAVE BEEN AVOIDED IF THE ACFT WAS PUSHED OFF THE GATE BY A TUG; RATHER THAN BEING REQUIRED TAXI FROM THE GATE UNDER ITS OWN PWR. THE PROX OF THE ENG TO THE JETBRIDGE IS TOO CLOSE TO ENSURE ENOUGH CLRNC FROM THE JETBLAST EVEN WITH 2 ENGS.
