Narrative:
Landing sfo. At point we normally change to tower, we received several (about 3) TA's with no altitude readout. Approach didn't tell us to switch to tower. Winds were gusty at 33 KTS, gusts to 42 KTS, but down the runway. After landing, we realized we were still on approach frequency. I called tower on phone from gate. We had been cleared to land and there were no conflicts. Contributing factors: fifth leg of day after minimum rest the night before. Turbulence on approach. My workload increased as the PF. The 3 RA's on final also distraction us at the point we normally switch to tower.

Narrative: LNDG SFO. AT POINT WE NORMALLY CHANGE TO TWR, WE RECEIVED SEVERAL (ABOUT 3) TA'S WITH NO ALT READOUT. APCH DIDN'T TELL US TO SWITCH TO TWR. WINDS WERE GUSTY AT 33 KTS, GUSTS TO 42 KTS, BUT DOWN THE RWY. AFTER LNDG, WE REALIZED WE WERE STILL ON APCH FREQ. I CALLED TWR ON PHONE FROM GATE. WE HAD BEEN CLRED TO LAND AND THERE WERE NO CONFLICTS. CONTRIBUTING FACTORS: FIFTH LEG OF DAY AFTER MINIMUM REST THE NIGHT BEFORE. TURB ON APCH. MY WORKLOAD INCREASED AS THE PF. THE 3 RA'S ON FINAL ALSO DISTR US AT THE POINT WE NORMALLY SWITCH TO TWR.
