Narrative:

ILS runway 28R in sfo was inoperative. We were going to fly a visual approach. While with approach control we were switched to ILS runway 28R. Again, reprogram the FMC and re-brief the approach. Then still with approach control and outside the marker, we were told that the ILS runway 28R is back up and to plan for runway 28R. So, once again reprogram, re-brief, and comply with new speed and traffic instructions from approach. Ok, now we are back on runway 28R. They asked us to maintain 170 KTS and have neither asked us to switch to tower nor requested us to call tower at the marker. The result was that we remained on approach frequency throughout the approach and landing and were given green light as landing clearance from tower. The rest was uneventful. I have no idea why they didn't ask us to switch to tower frequency and obviously we didn't inquire about it at the time. Maybe the reason we didn't ask was because we were given so many changes and instructions on the very same final approach, it would just seem normal to be 'handed over' to the next frequency. Supplemental information from acn 538718: approach failed to hand us off to tower and we landed without radio clearance. No distractions below 10000 ft, sterile cockpit, no complacency, just lack of currency. Captain had not flown B757 in 8 months, flew nothing for last 6 months due to surgery. Had 6 legs of IOE followed by 3 weeks vacation. This was my first flight out as captain. First officer had 5 legs on B757 after being off of it for 1 yr while flying captain on DC9. My 1000 ft check of spoilers, miss approach altitude and nose gear light (my signal that we've been cleared to land) failed us, since I forgot the nose gear light in my scan. I'd suggest tighter control over currency in cockpit when pilots are in a massive shuffle as we're experiencing now, ie, 09/tue/01 air carrier furloughs. P.south. Tower shot us a continuous green light for landing.

Title: B757-200 CREW DID NOT CONTACT SFO TWR FOR LNDG CLRNC. ATCT LCL CTLR GAVE CREW A CONTINUOUS 'GREEN LIGHT' FOR LNDG CLRNC.

Narrative: ILS RWY 28R IN SFO WAS INOP. WE WERE GOING TO FLY A VISUAL APCH. WHILE WITH APCH CTL WE WERE SWITCHED TO ILS RWY 28R. AGAIN, REPROGRAM THE FMC AND RE-BRIEF THE APCH. THEN STILL WITH APCH CTL AND OUTSIDE THE MARKER, WE WERE TOLD THAT THE ILS RWY 28R IS BACK UP AND TO PLAN FOR RWY 28R. SO, ONCE AGAIN REPROGRAM, RE-BRIEF, AND COMPLY WITH NEW SPD AND TFC INSTRUCTIONS FROM APCH. OK, NOW WE ARE BACK ON RWY 28R. THEY ASKED US TO MAINTAIN 170 KTS AND HAVE NEITHER ASKED US TO SWITCH TO TWR NOR REQUESTED US TO CALL TWR AT THE MARKER. THE RESULT WAS THAT WE REMAINED ON APCH FREQ THROUGHOUT THE APCH AND LNDG AND WERE GIVEN GREEN LIGHT AS LNDG CLRNC FROM TWR. THE REST WAS UNEVENTFUL. I HAVE NO IDEA WHY THEY DIDN'T ASK US TO SWITCH TO TWR FREQ AND OBVIOUSLY WE DIDN'T INQUIRE ABOUT IT AT THE TIME. MAYBE THE REASON WE DIDN'T ASK WAS BECAUSE WE WERE GIVEN SO MANY CHANGES AND INSTRUCTIONS ON THE VERY SAME FINAL APCH, IT WOULD JUST SEEM NORMAL TO BE 'HANDED OVER' TO THE NEXT FREQ. SUPPLEMENTAL INFO FROM ACN 538718: APCH FAILED TO HAND US OFF TO TWR AND WE LANDED WITHOUT RADIO CLRNC. NO DISTRACTIONS BELOW 10000 FT, STERILE COCKPIT, NO COMPLACENCY, JUST LACK OF CURRENCY. CAPT HAD NOT FLOWN B757 IN 8 MONTHS, FLEW NOTHING FOR LAST 6 MONTHS DUE TO SURGERY. HAD 6 LEGS OF IOE FOLLOWED BY 3 WKS VACATION. THIS WAS MY FIRST FLT OUT AS CAPT. FO HAD 5 LEGS ON B757 AFTER BEING OFF OF IT FOR 1 YR WHILE FLYING CAPT ON DC9. MY 1000 FT CHK OF SPOILERS, MISS APCH ALT AND NOSE GEAR LIGHT (MY SIGNAL THAT WE'VE BEEN CLRED TO LAND) FAILED US, SINCE I FORGOT THE NOSE GEAR LIGHT IN MY SCAN. I'D SUGGEST TIGHTER CTL OVER CURRENCY IN COCKPIT WHEN PLTS ARE IN A MASSIVE SHUFFLE AS WE'RE EXPERIENCING NOW, IE, 09/TUE/01 ACR FURLOUGHS. P.S. TWR SHOT US A CONTINUOUS GREEN LIGHT FOR LNDG.
