Narrative:

I was the PF to dfw on a good WX day when the approach controller offered a runway change to expedite our arrival. Our acceptance to change from runway 36L to runway 35C required us to remain higher to avoid traffic to the parallel runway. The aircraft required numerous confign changes to go down/slow down to prepare for landing. Approach told us to switch to tower at the FAF. We completed all checklists and landed without calling tower. Upon rollout we discovered our mistake, switched to tower for the clearance which had been issued, but not acknowledged. Distractions of checklists, visual separation, confign changes and concern for a stabilized approach contributed to our error. Workload management, and reviewing priorities could have helped prevent this, as well as the use of our pneumatic crutch of a light switch could have saved us from missing the call. Supplemental information from acn 472198: I acknowledged the frequency change, but got distracted by other duties (before landing checklist) and forgot to switch to tower frequency.

Title: AN MD88 FLC LANDS WITHOUT CLRNC WHILE STILL ON APCH CTL FREQ AFTER A RWY CHANGE AT DFW, TX.

Narrative: I WAS THE PF TO DFW ON A GOOD WX DAY WHEN THE APCH CTLR OFFERED A RWY CHANGE TO EXPEDITE OUR ARR. OUR ACCEPTANCE TO CHANGE FROM RWY 36L TO RWY 35C REQUIRED US TO REMAIN HIGHER TO AVOID TFC TO THE PARALLEL RWY. THE ACFT REQUIRED NUMEROUS CONFIGN CHANGES TO GO DOWN/SLOW DOWN TO PREPARE FOR LNDG. APCH TOLD US TO SWITCH TO TWR AT THE FAF. WE COMPLETED ALL CHKLISTS AND LANDED WITHOUT CALLING TWR. UPON ROLLOUT WE DISCOVERED OUR MISTAKE, SWITCHED TO TWR FOR THE CLRNC WHICH HAD BEEN ISSUED, BUT NOT ACKNOWLEDGED. DISTRACTIONS OF CHKLISTS, VISUAL SEPARATION, CONFIGN CHANGES AND CONCERN FOR A STABILIZED APCH CONTRIBUTED TO OUR ERROR. WORKLOAD MGMNT, AND REVIEWING PRIORITIES COULD HAVE HELPED PREVENT THIS, AS WELL AS THE USE OF OUR PNEUMATIC CRUTCH OF A LIGHT SWITCH COULD HAVE SAVED US FROM MISSING THE CALL. SUPPLEMENTAL INFO FROM ACN 472198: I ACKNOWLEDGED THE FREQ CHANGE, BUT GOT DISTRACTED BY OTHER DUTIES (BEFORE LNDG CHKLIST) AND FORGOT TO SWITCH TO TWR FREQ.
