Narrative:
Cleared visual behind another inbound aircraft. Approach gave frequency change to tower. First officer dialed in frequency but was then asked by captain if he still had other aircraft in sight. Due to having attention diverted, switch was never placed on tower frequency and a call was never made. Spacing on landing aircraft was minimal and crew's attention was fixated on visual approach and spacing. After landing, crew realized they were still on approach frequency. Supplemental information from acn 425345: we were cleared for a visual approach to runway 12R, following another aircraft. Sat approach control gave us a frequency change to sat tower. I entered the frequency into the standby side of the radio. I did not 'FLIP the switch' to activate the tower frequency. We landed while still on approach frequency, without landing clearance. Contributing factors: high workload -- 2 man crew. End of long day with some flight segments in bad WX. Fatigue.

Title: ACR MD88 FLC, DISTR WHILE CONFIGURING FOR LNDG, FORGETS TO CALL TWR FOR LNDG CLRNC.
Narrative: CLRED VISUAL BEHIND ANOTHER INBOUND ACFT. APCH GAVE FREQ CHANGE TO TWR. FO DIALED IN FREQ BUT WAS THEN ASKED BY CAPT IF HE STILL HAD OTHER ACFT IN SIGHT. DUE TO HAVING ATTN DIVERTED, SWITCH WAS NEVER PLACED ON TWR FREQ AND A CALL WAS NEVER MADE. SPACING ON LNDG ACFT WAS MINIMAL AND CREW'S ATTN WAS FIXATED ON VISUAL APCH AND SPACING. AFTER LNDG, CREW REALIZED THEY WERE STILL ON APCH FREQ. SUPPLEMENTAL INFO FROM ACN 425345: WE WERE CLRED FOR A VISUAL APCH TO RWY 12R, FOLLOWING ANOTHER ACFT. SAT APCH CTL GAVE US A FREQ CHANGE TO SAT TWR. I ENTERED THE FREQ INTO THE STANDBY SIDE OF THE RADIO. I DID NOT 'FLIP THE SWITCH' TO ACTIVATE THE TWR FREQ. WE LANDED WHILE STILL ON APCH FREQ, WITHOUT LNDG CLRNC. CONTRIBUTING FACTORS: HIGH WORKLOAD -- 2 MAN CREW. END OF LONG DAY WITH SOME FLT SEGMENTS IN BAD WX. FATIGUE.
