Narrative:

It was late in the afternoon of our 4TH day of flying, and the captain was at the controls. Visibility was 4 mi (mvf) in haze at dfw, so we were vectored for an ILS to runway 31R at dfw. We were cleared for the approach, and I made all the appropriate callouts, including 'no flags, gear down, cleared to land.' after we landed, I realized that we had not switched to tower frequency, and were still on approach. I told the captain, and he instructed me to contact the tower. I did, and the controller asked if I had heard his xmissions. I confessed that we had not switched to his frequency, and apologized. He said not to worry, and gave us further instructions. I believe that the cause of this deviation from the regulations was complacency. It had been visual approachs all week, and we had not 'geared up' our minds for a 'real' ILS approach. I lost focus and made the callout 'cleared to land' without giving it any meaning. I was just going through the motions. From now on, I will pay more attention, focus on the task at hand, and think about the meaning of the callouts that we give dozens of times every month.

Title: AN EMB120 FLC LANDS AT DFW WITHOUT BENEFIT OF A LNDG CLRNC. FO FORGOT TO SWITCH TO TWR, EVEN AFTER STATING 'CLRED TO LAND' DURING HIS SHORT FINAL 'MANTRA.'

Narrative: IT WAS LATE IN THE AFTERNOON OF OUR 4TH DAY OF FLYING, AND THE CAPT WAS AT THE CTLS. VISIBILITY WAS 4 MI (MVF) IN HAZE AT DFW, SO WE WERE VECTORED FOR AN ILS TO RWY 31R AT DFW. WE WERE CLRED FOR THE APCH, AND I MADE ALL THE APPROPRIATE CALLOUTS, INCLUDING 'NO FLAGS, GEAR DOWN, CLRED TO LAND.' AFTER WE LANDED, I REALIZED THAT WE HAD NOT SWITCHED TO TWR FREQ, AND WERE STILL ON APCH. I TOLD THE CAPT, AND HE INSTRUCTED ME TO CONTACT THE TWR. I DID, AND THE CTLR ASKED IF I HAD HEARD HIS XMISSIONS. I CONFESSED THAT WE HAD NOT SWITCHED TO HIS FREQ, AND APOLOGIZED. HE SAID NOT TO WORRY, AND GAVE US FURTHER INSTRUCTIONS. I BELIEVE THAT THE CAUSE OF THIS DEV FROM THE REGS WAS COMPLACENCY. IT HAD BEEN VISUAL APCHS ALL WK, AND WE HAD NOT 'GEARED UP' OUR MINDS FOR A 'REAL' ILS APCH. I LOST FOCUS AND MADE THE CALLOUT 'CLRED TO LAND' WITHOUT GIVING IT ANY MEANING. I WAS JUST GOING THROUGH THE MOTIONS. FROM NOW ON, I WILL PAY MORE ATTN, FOCUS ON THE TASK AT HAND, AND THINK ABOUT THE MEANING OF THE CALLOUTS THAT WE GIVE DOZENS OF TIMES EVERY MONTH.
