Narrative:

On a flight from las to sfo during a scheduled air carrier operation, we were being vectored for a visual approach to runway 19L. WX conditions were VMC with clouds at numerous layers and widely scattered down to approximately 1000 ft. At approximately 11 mi from sfo and slightly left of the localizer to runway 19L we called runway in sight. Bay approach issued the clearance 'cleared for a visual to runway 19L maintain 3000 ft till reaching the sfo 8 DME.' I intercepted the localizer just inside shake intersection. The captain switched to the sfo VOR to determine 8 DME. I was required to deviate approximately 2 dots high on the approach to comply with the crossing restr. At this time the altitude restr caused our attention to be diverted to the task of rejoining a normal approach path to facilitate a stabilized approach in compliance with our operations manual. Upon landing, both myself and the captain noticed that tower frequency was not selected on the audio panel. This caused us to question whether or not we received landing clearance. The captain took control of the aircraft for the taxi off runway 19L to hold short of runway 19R. I tuned in tower and the controller cleared us across runway 19R. After we crossed runway 19R I tuned in ground control and we were issued a taxi clearance to the gate.

Title: AN ACR B737 LANDED WITHOUT A CLRNC ON RWY 19L AT SFO. THE CAPT FORGOT TO SWITCH TO TWR DURING THE FO'S APCH.

Narrative: ON A FLT FROM LAS TO SFO DURING A SCHEDULED ACR OP, WE WERE BEING VECTORED FOR A VISUAL APCH TO RWY 19L. WX CONDITIONS WERE VMC WITH CLOUDS AT NUMEROUS LAYERS AND WIDELY SCATTERED DOWN TO APPROX 1000 FT. AT APPROX 11 MI FROM SFO AND SLIGHTLY L OF THE LOC TO RWY 19L WE CALLED RWY IN SIGHT. BAY APCH ISSUED THE CLRNC 'CLRED FOR A VISUAL TO RWY 19L MAINTAIN 3000 FT TILL REACHING THE SFO 8 DME.' I INTERCEPTED THE LOC JUST INSIDE SHAKE INTXN. THE CAPT SWITCHED TO THE SFO VOR TO DETERMINE 8 DME. I WAS REQUIRED TO DEVIATE APPROX 2 DOTS HIGH ON THE APCH TO COMPLY WITH THE XING RESTR. AT THIS TIME THE ALT RESTR CAUSED OUR ATTN TO BE DIVERTED TO THE TASK OF REJOINING A NORMAL APCH PATH TO FACILITATE A STABILIZED APCH IN COMPLIANCE WITH OUR OPS MANUAL. UPON LNDG, BOTH MYSELF AND THE CAPT NOTICED THAT TWR FREQ WAS NOT SELECTED ON THE AUDIO PANEL. THIS CAUSED US TO QUESTION WHETHER OR NOT WE RECEIVED LNDG CLRNC. THE CAPT TOOK CTL OF THE ACFT FOR THE TAXI OFF RWY 19L TO HOLD SHORT OF RWY 19R. I TUNED IN TWR AND THE CTLR CLRED US ACROSS RWY 19R. AFTER WE CROSSED RWY 19R I TUNED IN GND CTL AND WE WERE ISSUED A TAXI CLRNC TO THE GATE.
