B757 FLT CREW DEP FROM PHX FAILED TO RECOGNIZE PDC ROUTING CHANGE.

Narrative

THE CAPT LOADED THE COMPANY FLT PLAN ROUTING INTO THE FMS THEN WAS CHKED FOR ACCURACY BY THE FO. PRIOR TO DEP; THE PDC CONTAINING THE FINAL ATC CLRNC WAS DELIVERED TO THE ACFT VIA ACARS FOLLOWED BY A HARD COPY FROM THE GATE AGENT WHO DELIVERED THE FINAL PAPERWORK. THE FINAL ATC CLRNC ON THE PDC CHANGED THE DEP SID. BOTH PLTS FAILED TO NOTE THE CHANGE OF THE SJN2 TO THE DRYHT2. THIS; DESPITE THE FACT THE FLT NUMBER WAS VERIFIED; AND THE DEP FREQ; XPONDER CODE; AND FIRST FILED ALT WERE ALL NOTED AND LOADED INTO THE RADIOS AND FLT GUIDANCE. PRIOR TO DEP OFF OF RWY 25R THE SNJ2 SID WAS BRIEFED THEN WE FLEW THE DEP AS BRIEFED. WHEN THE ACFT REACHED 1550 FT MSL; A SHALLOW R TURN TO A HEADING OF 260 DEGS WAS INITIATED; AS REQUIRED BY THE SJN2 SID; INSTEAD OF TURN TO THE L TO A HEADING OF 240 DEGS AS WAS REQUIRED BY THE DRYHT2 SID. WITHIN A FEW SECONDS OF CONTACTING DEP CTL AT AROUND 2000 FT MSL; OUR ERROR WAS DETECTED BY THE CTLR AND WE WERE IMMEDIATELY TURNED TO COMPLY WITH THE DRYHT2 SID. WE WERE NOT AWARE OF ANY TFC CONFLICTS DURING THIS INCIDENT. THERE WERE NO TCASII ALERTS. WHILE ENRTE; THE PLTS REVIEWED THE EVENTS THAT LED UP TO THIS ERROR. BOTH PLTS ARE AWARE OF THE PITFALL OF MISSING THE REVISED ATC CLRNC ON THE PDC AND HAVE HABIT PATTERNS THAT WE USE TO HELP US TO KEEP THIS FROM HAPPENING. OUR HABIT PATTERNS FAILED US IN THIS INSTANCE. WE BOTH FEEL THAT A CONTRIBUTING FACTOR TO THIS TYPE OF ERROR IS THE FORMAT OF THE PDC ITSELF WHICH BREAKS UP CLRNC INSTEAD OF PRESENTING IT IN ONE PIECE. WE FOUND THAT WE BOTH READ THE PDC IN A SIMILAR MANNER. WE CHK THE FLT NUMBER AND XPONDER CODE NEAR THE TOP OF THE PDC THEN DROP DOWN TO THE BOTTOM OF THE PDC TO GET THE INITIAL ALT AND DEP FREQ. NEXT WE MOVE BACK TO THE MIDDLE OF THE MESSAGE FOR DEP ROUTING AND ATC CLRNC. IN THIS CASE WE BOTH; FOR WHATEVER REASON; STOPPED AT THE FILED RTE BLOCK AND DID NOT PROCEED UP TO THE ATC 'CLRED AS FILED' BLOCK.
