Narrative

WHILE TAXIING TO GATE XA; THERE WAS A LIGHT RAIN; HOWEVER THIS WAS NOT A FACTOR THAT OBSTRUCTED MY VISION WHILE I CONTINUED TO THE GATE. I WAS DOING A SINGLE ENG TAXI AT A NORMAL SPD (WALKING SPD); I NOTICED A TRUCK PARKED (ONLY 1 VEHICLE IN THE AREA) TO THE R SIDE OF THE GATE SAFETY AREA. FROM MY POS; IT WAS DIFFICULT TO DETERMINE THE TRUCK'S DISTANCE AND HT. FROM MY PERSPECTIVE; IT APPEARED TO ME THAT THE AREA WAS CLR. I COULD STILL SEE THE MARSHALLER SIGNALING ME TO CONTINUE INBOUND; THUS RECONFIRMING THAT IT WAS SAFE. I CONTINUED TO FOLLOW INSTRUCTIONS FROM THE MARSHALLER TO HELP ME GUIDE IN THE ACFT; WHO HAD COMPLETE VISUAL REF OF THE SURROUNDINGS. AS I APCHED THE GATE AREA FOLLOWING THE TAXI LINE AND INSTRUCTIONS FROM THE MARSHALLER; I PROCEEDED TO MAKE A SMALL ARCH TO THE L THEN R (FOLLOWING THE TAXI LINE) IN ORDER FOR THE AIRPLANE TO BE ALIGNED WITH THE GATE. ONCE STRAIGHTENING THE AIRPLANE; AND ON THE TAXI LINE; I CONFIRMED WITH MY FO THAT THE AREA WAS CLR. THE FO WAS LOOKING OUT THE R SIDE OF THE AIRPLANE AND WAS ALSO FOLLOWING INSTRUCTIONS FROM THE MARSHALLER. THE INSTRUCTIONS I KEPT RECEIVING FROM THE MARSHALLER WERE TO MOVE FORWARD AND THAT THE ACFT WAS CLR OF OBSTACLES AND SAFE TO PROCEED. ACCORDING TO PROCS; I WAS FOLLOWING INSTRUCTIONS FORM THE MARSHALLING AGENT TO CONTINUE APCHING THE GATE. AS WE GOT CLOSER TO THE GATE AREA; I FELT A SLIGHT JOLT; AND MY FO ADVISED ME THAT WE HAD STRUCK A PARKED TRUCK. AT NO TIME THE AGENT MARSHALLING THE ACFT SIGNALED FOR ME TO STOP. IMMEDIATELY AFTER IMPACT; I APPLIED THE BRAKES; AND I PROCEEDED TO SHUT DOWN THE REMAINING ENG. I NOTICED THE MARSHALLER STILL SIGNALING ME TO CONTINUE MOVING THE AIRPLANE FORWARD. I THEN SIGNALED THE MARSHALLER TO HAVE THE AIRPLANE TOWED TO THE GATE. WE COMPLETED THE ENG SHUTDOWN CHKLIST; AND MY FO GAVE AN ANNOUNCEMENT EXPLAINING THE SIT AND FOR ALL PAX TO REMAIN SEATED WITH THEIR SEAT BELTS FASTENED. RAMP PERSONNEL TOWED THE ACFT INTO THE GATE.
