Narrative:

Missed clearance. Our company filed flight plan was kslc.slc.J9.mlf.2107.hec.J64 civet.CIVET3.klax. In our cockpit preparation, we had the pre departure clearance, but didn't catch the fairly subtle change to our actual clearance ffu.j11xj107.mlf then as filed. Didn't catch the problem until quizzed by center, and even then we initially thought we were correct. We failed to read the pre departure clearance carefully. Contributing: 1) day 4 of a long 4-DAY trip. 2) a highly experienced line check captain leading to first officer complacency in verifying the flight plan in the computer. 3) late equipment arrival, and the subsequent scramble to get out on time made me even later arriving in cockpit. 4) the heading 'flight plan routing' in the pre departure clearance, below the heading 'ATC clearance.' you can accidentally read the wrong part. Also, the pre departure clearance always says 'ATC clearance...' and 'flight plan routing....' perhaps it should only say 'as filed' if there are no changes, and 'ATC clearance' if there are -- something to get your attention. Supplemental information from acn 238505: during preflight, the first officer retrieved our ATC clearance via our touch screen ACARS. This aircraft did not have a printer. He brought it up on the screen, and we both read each page and made the appropriate settings which included the filed route then the cleared route. Neither one of us caught the difference in the route.

Title: AN ACR LGT MISREAD ITS PDC AND ATTEMPTED TO FLY THE WRONG DEP PROFILE.

Narrative: MISSED CLRNC. OUR COMPANY FILED FLT PLAN WAS KSLC.SLC.J9.MLF.2107.HEC.J64 CIVET.CIVET3.KLAX. IN OUR COCKPIT PREPARATION, WE HAD THE PDC, BUT DIDN'T CATCH THE FAIRLY SUBTLE CHANGE TO OUR ACTUAL CLRNC FFU.J11XJ107.MLF THEN AS FILED. DIDN'T CATCH THE PROB UNTIL QUIZZED BY CTR, AND EVEN THEN WE INITIALLY THOUGHT WE WERE CORRECT. WE FAILED TO READ THE PDC CAREFULLY. CONTRIBUTING: 1) DAY 4 OF A LONG 4-DAY TRIP. 2) A HIGHLY EXPERIENCED LINE CHK CAPT LEADING TO FO COMPLACENCY IN VERIFYING THE FLT PLAN IN THE COMPUTER. 3) LATE EQUIP ARR, AND THE SUBSEQUENT SCRAMBLE TO GET OUT ON TIME MADE ME EVEN LATER ARRIVING IN COCKPIT. 4) THE HDG 'FLT PLAN ROUTING' IN THE PDC, BELOW THE HDG 'ATC CLRNC.' YOU CAN ACCIDENTALLY READ THE WRONG PART. ALSO, THE PDC ALWAYS SAYS 'ATC CLRNC...' AND 'FLT PLAN ROUTING....' PERHAPS IT SHOULD ONLY SAY 'AS FILED' IF THERE ARE NO CHANGES, AND 'ATC CLRNC' IF THERE ARE -- SOMETHING TO GET YOUR ATTN. SUPPLEMENTAL INFO FROM ACN 238505: DURING PREFLT, THE FO RETRIEVED OUR ATC CLRNC VIA OUR TOUCH SCREEN ACARS. THIS ACFT DID NOT HAVE A PRINTER. HE BROUGHT IT UP ON THE SCREEN, AND WE BOTH READ EACH PAGE AND MADE THE APPROPRIATE SETTINGS WHICH INCLUDED THE FILED RTE THEN THE CLRED RTE. NEITHER ONE OF US CAUGHT THE DIFFERENCE IN THE RTE.
