EFLAG. A B727-200 FLC STARTS THE APCH TO RWY 29 ILS APCH WHEN ONLY CLRED FOR THE LOC INTERCEPT. IN DSCNT THEY RECEIVE AN RA FOR UNRPTED TFC 10 MI ESE OF OAK; CA.

Narrative

WHILE IMC AT 4000 FT ON APCH TO OAKLAND; WE WERE GIVEN A 230 DEG HDG TO INTERCEPT THE RWY 29 LOC. BECAUSE OF THE LARGE INTERCEPT ANGLE 230-294 DEGS (64 DEGS) AND NOT WANTING A BIG OVERSHOOT; THE AUTOPLT WAS DISCONNECTED. THESE PARAMETERS ALSO EXCEED THE AUTOPLT'S CAPABILITIES. THE PNF WAS READING OUT RADIALS FROM THE OAK VOR TO AID THE PF IN THE INTERCEPT. DURING THE TURN FOR THE LOC; IT WAS NOTICED WE WERE BEGINNING TO GO HIGH ON THE GS. AFTER A BRIEF DISCUSSION IN THE COCKPIT; AND ALSO DURING A CRITICAL PHASE OF THE APCH; IT WAS DECIDED THAT WE WERE IN FACT CLRED FOR THE APCH. THE DSCNT WAS STARTED WHILE INITIATING THE TURN TO THE OTHER SIDE OF THE LOC BECAUSE OF THE OVERSHOOT. CONVERGING TFC WAS NOTICED ON TCASII BEFORE THE RA WAS INITIATED. AFTER FOLLOWING THE RA AND THEN HEARING THE 'CLR OF CONFLICT;' WE HAD A VISUAL ON OAK RWY 29. THE APCH AND LNDG WERE CONTINUED VISUALLY FOR AN UNEVENTFUL LNDG AT OAKLAND. IT WAS NOT UNTIL WE VACATED THE PLANE AND WERE IN OPS THAT WE WERE CONTACTED BY ATC. IT WAS DURING THIS TIME THAT WE WERE TOLD THAT WE WERE NEVER CLRED FOR THE APCH. FACTORS: AFTER MONTHS OF FLYING VISUAL APCHS; THIS WAS THE FIRST INST APCH OF THE SEASON. WE WERE TASK SATURATED WITH ALL THE CONCERNS OF THE WAY THE APCH WAS BEING HANDLED BY ATC. HAD THE ATC CTLR TOLD US HE WAS GOING TO TAKE US THROUGH THE LOC AND KEEP US HIGH ON GS BECAUSE OF CONFLICTING TFC; WE WOULD NOT HAVE BEEN PUT IN THIS POS. IT WAS REALIZED THAT WHEN YOU'RE THAT BUSY YOU HAD PROBABLY MISSED A COUPLE EXCHANGES WITH ATC; SO NO ONE CHALLENGED FOR A CONFIRMATION. PERHAPS; ALSO; A FEELING THAT WE WERE APCHING OUR HOME FIELD AND FAMILIAR TERRITORY THAT OUR GUARD WAS DOWN. WE WERE DOING WHAT WE'VE DONE A HUNDRED TIMES BEFORE. FATIGUE -- THIS PARTICULAR TRIP INVOLVES A 30 HR TIME AWAY. DURING THESE 30 HRS; THERE IS 17 HRS OF DUTY TIME AND 11 HRS OF FLT TIME. ALL THIS JUST BARELY STAYING WITHIN THE 8 IN 24 HRS.
