Narrative:

I was taxiing to gate at phl. I noticed the area around the gate was clear of ground service vehicles and the jetway appeared the normal distance back from the lead-in line to the gate. As I centered the nosewheel on this line, I observed the marshaller waving me into the gate. I followed his lead-in until I felt the aircraft stop. He continued to wave me forward. As I started to add power, he then signaled to stop and walked over to the jetway. I looked out the cockpit window and realized that I had hit the jetway with the #1 engine cowling. My misjudgement came when I only saw that the jetway was a safe distance back from the lead-in line and did not notice how far out the jetway was from the terminal. Once I observed the marshaller, I took my eyes off the jetway and followed his instructions. The jetway was used previously with a B757 L2 passenger entry door and had not been moved closer to the terminal to match the passenger entry door (L1) of the next inbound flight to that gate, which was a B737-400 (my flight). Supplemental information from acn: 387451: immediate investigation of incident produced corrective action by station supervisors as to location of jetway and marshalling. Pilots are more aware to ensure jetway clearance when approaching the jetway cabin attendant and after it passes abeam and aft of the cockpit window.

Title: A B737-400 BEING GUIDED ONTO A GATE STRUCK A PARKED, OUT OF POS JETWAY INCURRING DAMAGE TO THE #1 ENG INLET COWL.

Narrative: I WAS TAXIING TO GATE AT PHL. I NOTICED THE AREA AROUND THE GATE WAS CLR OF GND SVC VEHICLES AND THE JETWAY APPEARED THE NORMAL DISTANCE BACK FROM THE LEAD-IN LINE TO THE GATE. AS I CTRED THE NOSEWHEEL ON THIS LINE, I OBSERVED THE MARSHALLER WAVING ME INTO THE GATE. I FOLLOWED HIS LEAD-IN UNTIL I FELT THE ACFT STOP. HE CONTINUED TO WAVE ME FORWARD. AS I STARTED TO ADD PWR, HE THEN SIGNALED TO STOP AND WALKED OVER TO THE JETWAY. I LOOKED OUT THE COCKPIT WINDOW AND REALIZED THAT I HAD HIT THE JETWAY WITH THE #1 ENG COWLING. MY MISJUDGEMENT CAME WHEN I ONLY SAW THAT THE JETWAY WAS A SAFE DISTANCE BACK FROM THE LEAD-IN LINE AND DID NOT NOTICE HOW FAR OUT THE JETWAY WAS FROM THE TERMINAL. ONCE I OBSERVED THE MARSHALLER, I TOOK MY EYES OFF THE JETWAY AND FOLLOWED HIS INSTRUCTIONS. THE JETWAY WAS USED PREVIOUSLY WITH A B757 L2 PAX ENTRY DOOR AND HAD NOT BEEN MOVED CLOSER TO THE TERMINAL TO MATCH THE PAX ENTRY DOOR (L1) OF THE NEXT INBOUND FLT TO THAT GATE, WHICH WAS A B737-400 (MY FLT). SUPPLEMENTAL INFO FROM ACN: 387451: IMMEDIATE INVESTIGATION OF INCIDENT PRODUCED CORRECTIVE ACTION BY STATION SUPVRS AS TO LOCATION OF JETWAY AND MARSHALLING. PLTS ARE MORE AWARE TO ENSURE JETWAY CLRNC WHEN APCHING THE JETWAY CAB AND AFTER IT PASSES ABEAM AND AFT OF THE COCKPIT WINDOW.
