Narrative:

We pushed back from gate. We received clearance from ground control to taxi to the deice pad via taxiway left and K. We commenced to taxi on taxiway left (our nosewheel on the taxiway centerline). As we proceeded, I noticed 2 commuter busses (ahead and to our left) parked at area designated for commuter flts. The busses were parked 4-5 ft outside of the double yellow lines of taxiway left. As we passed by this area where the busses were parked, I felt a jolt upon impact with our left wingtip and the bus. The captain immediately stopped the aircraft. We called operations, deplaned the passenger and secured the aircraft. In my opinion, taxiway left needs to be widened to assure proper clearance when an aircraft is on taxiway centerline.

Title: TAXIING ACFT HITS PARKED BUSSES WHILE ON TXWY CTRLINE.

Narrative: WE PUSHED BACK FROM GATE. WE RECEIVED CLRNC FROM GND CTL TO TAXI TO THE DEICE PAD VIA TXWY L AND K. WE COMMENCED TO TAXI ON TXWY L (OUR NOSEWHEEL ON THE TXWY CTRLINE). AS WE PROCEEDED, I NOTICED 2 COMMUTER BUSSES (AHEAD AND TO OUR L) PARKED AT AREA DESIGNATED FOR COMMUTER FLTS. THE BUSSES WERE PARKED 4-5 FT OUTSIDE OF THE DOUBLE YELLOW LINES OF TXWY L. AS WE PASSED BY THIS AREA WHERE THE BUSSES WERE PARKED, I FELT A JOLT UPON IMPACT WITH OUR L WINGTIP AND THE BUS. THE CAPT IMMEDIATELY STOPPED THE ACFT. WE CALLED OPS, DEPLANED THE PAX AND SECURED THE ACFT. IN MY OPINION, TXWY L NEEDS TO BE WIDENED TO ASSURE PROPER CLRNC WHEN AN ACFT IS ON TXWY CTRLINE.
