Narrative:

On approach to boston logan airport we were on downwind leg on vectors for ILS to runway 27. The WX was improving at the time so approach control offered us the ILS to runway 22L. They were now doing approachs to runways 22L and 27. We accepted the approach knowing that this would now put us initially high on the approach, but it was still within reason even though the B757 is an airplane that is very hard to get to come down. I was flying at the time, so the captain was now trying to insert the new approach to runway 22L into the FMC and also tune and set up the ILS. I was fighting to get the airplane slowed and also look at the approach. There was another plane behind us who was fairly close so the controller now turns us inside the marker. The WX was even better now and we could see the field. But, I was now higher than I planned, but still ok. We were also trying to help approach control by shortening the final so he could get the other aircraft in. After we were cleared for the ILS the final controller said emphatically 'hold short of runway 27.' we were only 2 mi from landing on runway 22L and were on speed and GS. A normal landing was made and we turned off on taxiway P which is short of intersecting runway 27. As we cleared the runway I realized we never talked to tower or got clearance to land. After talking to the tower supervisor from operations he listened to the tape and said things were ok. One problem, he said was that was just during a shift change plus a traffic pattern change and we had been turned inside the marker where he normally switches us to tower. The approach controller was now very busy just like we were and forgot to switch us over to tower. The bottom line is as the intensity of the workload increases the chance for mistakes greatly increases for both us and the controller.

Title: FLC LANDED WITHOUT TWR CLRNC. RUSHED ON APCH, CHANGING RWYS AND TRYING TO ACCOMMODATE APCH CTLR AND FOLLOWING ACFT, TURNED INSIDE THE MARKER, FLC FORGOT TO CONTACT TWR FOR CLRNC. LRG.

Narrative: ON APCH TO BOSTON LOGAN ARPT WE WERE ON DOWNWIND LEG ON VECTORS FOR ILS TO RWY 27. THE WX WAS IMPROVING AT THE TIME SO APCH CTL OFFERED US THE ILS TO RWY 22L. THEY WERE NOW DOING APCHS TO RWYS 22L AND 27. WE ACCEPTED THE APCH KNOWING THAT THIS WOULD NOW PUT US INITIALLY HIGH ON THE APCH, BUT IT WAS STILL WITHIN REASON EVEN THOUGH THE B757 IS AN AIRPLANE THAT IS VERY HARD TO GET TO COME DOWN. I WAS FLYING AT THE TIME, SO THE CAPT WAS NOW TRYING TO INSERT THE NEW APCH TO RWY 22L INTO THE FMC AND ALSO TUNE AND SET UP THE ILS. I WAS FIGHTING TO GET THE AIRPLANE SLOWED AND ALSO LOOK AT THE APCH. THERE WAS ANOTHER PLANE BEHIND US WHO WAS FAIRLY CLOSE SO THE CTLR NOW TURNS US INSIDE THE MARKER. THE WX WAS EVEN BETTER NOW AND WE COULD SEE THE FIELD. BUT, I WAS NOW HIGHER THAN I PLANNED, BUT STILL OK. WE WERE ALSO TRYING TO HELP APCH CTL BY SHORTENING THE FINAL SO HE COULD GET THE OTHER ACFT IN. AFTER WE WERE CLRED FOR THE ILS THE FINAL CTLR SAID EMPHATICALLY 'HOLD SHORT OF RWY 27.' WE WERE ONLY 2 MI FROM LNDG ON RWY 22L AND WERE ON SPD AND GS. A NORMAL LNDG WAS MADE AND WE TURNED OFF ON TXWY P WHICH IS SHORT OF INTERSECTING RWY 27. AS WE CLRED THE RWY I REALIZED WE NEVER TALKED TO TWR OR GOT CLRNC TO LAND. AFTER TALKING TO THE TWR SUPVR FROM OPS HE LISTENED TO THE TAPE AND SAID THINGS WERE OK. ONE PROB, HE SAID WAS THAT WAS JUST DURING A SHIFT CHANGE PLUS A TFC PATTERN CHANGE AND WE HAD BEEN TURNED INSIDE THE MARKER WHERE HE NORMALLY SWITCHES US TO TWR. THE APCH CTLR WAS NOW VERY BUSY JUST LIKE WE WERE AND FORGOT TO SWITCH US OVER TO TWR. THE BOTTOM LINE IS AS THE INTENSITY OF THE WORKLOAD INCREASES THE CHANCE FOR MISTAKES GREATLY INCREASES FOR BOTH US AND THE CTLR.
