Narrative:

Advised by operations about a very tight parking plan. Spot X was our planned parking spot with spot Y occupied by a jet and a dash 8 between spot X and Y. The plan was to marshall around the dash 8 and park near spot X. Ground equipment was stationed to the left of spot X. One marshaller and two wingwalkers were used. The marshaller guided us around the dash 8 with plenty of room; but a little too close to the ground equipment. The lead marshaller did not follow the guidance from the left wingwalker about the close ground equipment. The left wingwalker was not in view from the cockpit. We followed the marshaller's guidance to parking and stopped on his command. After parking we discovered the left sail had struck an airstair canopy. The sail missed clearing the canopy by about 2 inches in height. There did not seem to be any damage to the aircraft. The captain said he could not see the wingwalker or the wingtip due to night conditions; the tight quarters; and the need to pay close attention to the lead marshaller. Supplemental information from acn 662341: the guidance by the guideman positioned us well clear of the dash 8; but was too close to the ground equipment; including a mobile loading bridge with a canopy. Due to the darkness and my inability to see the wingwalker below and behind my wing; I followed the guideman's guidance exclusively. As I stopped the airplane on his command; I felt a slight jolt. After deplaning; we discovered that the left wing sail had made contact with the canopy of the mobile loading bridge.

Title: AN A319 WINGLET STRUCK A PORTABLE PAX LOADING STAIR ON A RAMP CONFINED BY 2 ACFT AND UNDER THE OBSERVATION OF 2 WINGWALKERS AND A MARSHALLER.

Narrative: ADVISED BY OPS ABOUT A VERY TIGHT PARKING PLAN. SPOT X WAS OUR PLANNED PARKING SPOT WITH SPOT Y OCCUPIED BY A JET AND A DASH 8 BETWEEN SPOT X AND Y. THE PLAN WAS TO MARSHALL AROUND THE DASH 8 AND PARK NEAR SPOT X. GND EQUIP WAS STATIONED TO THE L OF SPOT X. ONE MARSHALLER AND TWO WINGWALKERS WERE USED. THE MARSHALLER GUIDED US AROUND THE DASH 8 WITH PLENTY OF ROOM; BUT A LITTLE TOO CLOSE TO THE GND EQUIP. THE LEAD MARSHALLER DID NOT FOLLOW THE GUIDANCE FROM THE L WINGWALKER ABOUT THE CLOSE GND EQUIP. THE L WINGWALKER WAS NOT IN VIEW FROM THE COCKPIT. WE FOLLOWED THE MARSHALLER'S GUIDANCE TO PARKING AND STOPPED ON HIS COMMAND. AFTER PARKING WE DISCOVERED THE L SAIL HAD STRUCK AN AIRSTAIR CANOPY. THE SAIL MISSED CLEARING THE CANOPY BY ABOUT 2 INCHES IN HEIGHT. THERE DID NOT SEEM TO BE ANY DAMAGE TO THE ACFT. THE CAPT SAID HE COULD NOT SEE THE WINGWALKER OR THE WINGTIP DUE TO NIGHT CONDITIONS; THE TIGHT QUARTERS; AND THE NEED TO PAY CLOSE ATTENTION TO THE LEAD MARSHALLER. SUPPLEMENTAL INFO FROM ACN 662341: THE GUIDANCE BY THE GUIDEMAN POSITIONED US WELL CLEAR OF THE DASH 8; BUT WAS TOO CLOSE TO THE GND EQUIP; INCLUDING A MOBILE LOADING BRIDGE WITH A CANOPY. DUE TO THE DARKNESS AND MY INABILITY TO SEE THE WINGWALKER BELOW AND BEHIND MY WING; I FOLLOWED THE GUIDEMAN'S GUIDANCE EXCLUSIVELY. AS I STOPPED THE AIRPLANE ON HIS COMMAND; I FELT A SLIGHT JOLT. AFTER DEPLANING; WE DISCOVERED THAT THE L WING SAIL HAD MADE CONTACT WITH THE CANOPY OF THE MOBILE LOADING BRIDGE.
