Narrative:
I was flying approach and landing. Controller instructed us to contact tower at the marker. Captain neglected to switch frequency. 1 mi final we received clearance to land from approach frequency. After landing, ground asked if we had clearance to land. This situation is a human factors set-up. Corrective actions: 1) since the flight deck is busy during approach and landing, I believe in contacting tower during initial frequency change. That way it will not unintentionally be forgotten. 2) moving a switch, ie, wheel well light to place an action to a clearance. We do it for altitude and heading clrncs, by moving heading bugs and altitudes in the autoplt window.

Title: AN APCHING B737 GETS ITS LNDG CLRNC FROM APCH CTLR WHEN THE PIC FORGETS TO SWITCH TO THE TWR 1 MI FROM LNDG AT PHL, PA.
Narrative: I WAS FLYING APCH AND LNDG. CTLR INSTRUCTED US TO CONTACT TWR AT THE MARKER. CAPT NEGLECTED TO SWITCH FREQ. 1 MI FINAL WE RECEIVED CLRNC TO LAND FROM APCH FREQ. AFTER LNDG, GND ASKED IF WE HAD CLRNC TO LAND. THIS SIT IS A HUMAN FACTORS SET-UP. CORRECTIVE ACTIONS: 1) SINCE THE FLT DECK IS BUSY DURING APCH AND LNDG, I BELIEVE IN CONTACTING TWR DURING INITIAL FREQ CHANGE. THAT WAY IT WILL NOT UNINTENTIONALLY BE FORGOTTEN. 2) MOVING A SWITCH, IE, WHEEL WELL LIGHT TO PLACE AN ACTION TO A CLRNC. WE DO IT FOR ALT AND HDG CLRNCS, BY MOVING HDG BUGS AND ALTS IN THE AUTOPLT WINDOW.
