Narrative:

Was given WX much better than actual on ATIS. After passing 1000 ft AGL, was concerned with landing and when will we break out. In the change from good to bad WX, I did not get clearance to land. Nothing was said by tower. Supplemental information from acn 377110: approach instructed us to call tower at rev-up (OM) which was approximately 5 mi ahead. We acknowledged but got distraction by the WX which was evidently much worse than the latest ATIS. Add to this the checklists to be done and the instruction to maintain 170 KIAS till OM (which led to late confign for landing), the captain and myself forgot to contact tower and landed without clearance. To prevent this occurring in IMC when workload is high, suggest ATC (approach) not tell us to call tower a few mi ahead, but rather just tell us to contact tower now (whenever and wherever we may be) to avoid forgetting to change frequencys. Higher than standard speeds on approachs does not help in timely accomplishment of duties, either!

Original NASA ASRS Text

Title: A BUSY WORKING FLC ON AN LTT FORGETS TO OBTAIN LNDG CLRNC AT DTW, MI.

Narrative: WAS GIVEN WX MUCH BETTER THAN ACTUAL ON ATIS. AFTER PASSING 1000 FT AGL, WAS CONCERNED WITH LNDG AND WHEN WILL WE BREAK OUT. IN THE CHANGE FROM GOOD TO BAD WX, I DID NOT GET CLRNC TO LAND. NOTHING WAS SAID BY TWR. SUPPLEMENTAL INFO FROM ACN 377110: APCH INSTRUCTED US TO CALL TWR AT REV-UP (OM) WHICH WAS APPROX 5 MI AHEAD. WE ACKNOWLEDGED BUT GOT DISTR BY THE WX WHICH WAS EVIDENTLY MUCH WORSE THAN THE LATEST ATIS. ADD TO THIS THE CHKLISTS TO BE DONE AND THE INSTRUCTION TO MAINTAIN 170 KIAS TILL OM (WHICH LED TO LATE CONFIGN FOR LNDG), THE CAPT AND MYSELF FORGOT TO CONTACT TWR AND LANDED WITHOUT CLRNC. TO PREVENT THIS OCCURRING IN IMC WHEN WORKLOAD IS HIGH, SUGGEST ATC (APCH) NOT TELL US TO CALL TWR A FEW MI AHEAD, BUT RATHER JUST TELL US TO CONTACT TWR NOW (WHENEVER AND WHEREVER WE MAY BE) TO AVOID FORGETTING TO CHANGE FREQS. HIGHER THAN STANDARD SPDS ON APCHS DOES NOT HELP IN TIMELY ACCOMPLISHMENT OF DUTIES, EITHER!
