Narrative:

On approach into bmi, snow was falling. Was vectored to an ILS runway 20. WX was approximately 800 ft overcast, 2 mi visibility. Approach was routine, except that upon crossing the OM inbound, we were so busy with checklists that we neglected to contact tower and actually ended up landing without a clearance. Snow plows were on or in the vicinity of the runway at the time and I suppose there was a possibility of incursion with ground vehicles. However, by the time we finally switched over to tower from approach (just about into the landing) we heard tower had cleared runway of all vehicles and we had enough forward visibility to see that the runway was clear of traffic. We were going to call at the last min but tower was busy talking to the ground vehicles and we did not get a chance. I was flying at the time and should have been more vigilant and managed the cockpit more efficiently. I was hand flying without the flight director trying to stay as proficient as I can, but this increased the workload and concentration requirements. Not doublechking to see if a call to tower at the OM had been made, was a serious mistake. I was slightly fast on initial approach which made things even more rushed. Better planning and thinking ahead would have made the difference. Supplemental information from acn 423900: arriving into bmi at night with low ceilings, the captain and I had been flying since early morning (time of incident was XA20) and we were both fatigued. Captain asked for gear down before landing checks. I set the captain up, did the flows, crosschecked the navigation and did all the calls (aviate, navigation, communicate), except I forgot to report the marker inbound. As a result, we were never cleared to land and yet we landed. The captain and I discussed this and we blame ourselves for not catching the clearance to land. Contributing factors were fatigue, low WX, and creating a heavier workload with nonstandard callouts.

Title: FLC OF A JETSTREAM 41 LANDS WITHOUT CLRNC.

Narrative: ON APCH INTO BMI, SNOW WAS FALLING. WAS VECTORED TO AN ILS RWY 20. WX WAS APPROX 800 FT OVCST, 2 MI VISIBILITY. APCH WAS ROUTINE, EXCEPT THAT UPON XING THE OM INBOUND, WE WERE SO BUSY WITH CHKLISTS THAT WE NEGLECTED TO CONTACT TWR AND ACTUALLY ENDED UP LNDG WITHOUT A CLRNC. SNOW PLOWS WERE ON OR IN THE VICINITY OF THE RWY AT THE TIME AND I SUPPOSE THERE WAS A POSSIBILITY OF INCURSION WITH GND VEHICLES. HOWEVER, BY THE TIME WE FINALLY SWITCHED OVER TO TWR FROM APCH (JUST ABOUT INTO THE LNDG) WE HEARD TWR HAD CLRED RWY OF ALL VEHICLES AND WE HAD ENOUGH FORWARD VISIBILITY TO SEE THAT THE RWY WAS CLR OF TFC. WE WERE GOING TO CALL AT THE LAST MIN BUT TWR WAS BUSY TALKING TO THE GND VEHICLES AND WE DID NOT GET A CHANCE. I WAS FLYING AT THE TIME AND SHOULD HAVE BEEN MORE VIGILANT AND MANAGED THE COCKPIT MORE EFFICIENTLY. I WAS HAND FLYING WITHOUT THE FLT DIRECTOR TRYING TO STAY AS PROFICIENT AS I CAN, BUT THIS INCREASED THE WORKLOAD AND CONCENTRATION REQUIREMENTS. NOT DOUBLECHKING TO SEE IF A CALL TO TWR AT THE OM HAD BEEN MADE, WAS A SERIOUS MISTAKE. I WAS SLIGHTLY FAST ON INITIAL APCH WHICH MADE THINGS EVEN MORE RUSHED. BETTER PLANNING AND THINKING AHEAD WOULD HAVE MADE THE DIFFERENCE. SUPPLEMENTAL INFO FROM ACN 423900: ARRIVING INTO BMI AT NIGHT WITH LOW CEILINGS, THE CAPT AND I HAD BEEN FLYING SINCE EARLY MORNING (TIME OF INCIDENT WAS XA20) AND WE WERE BOTH FATIGUED. CAPT ASKED FOR GEAR DOWN BEFORE LNDG CHKS. I SET THE CAPT UP, DID THE FLOWS, XCHKED THE NAV AND DID ALL THE CALLS (AVIATE, NAV, COMMUNICATE), EXCEPT I FORGOT TO RPT THE MARKER INBOUND. AS A RESULT, WE WERE NEVER CLRED TO LAND AND YET WE LANDED. THE CAPT AND I DISCUSSED THIS AND WE BLAME OURSELVES FOR NOT CATCHING THE CLRNC TO LAND. CONTRIBUTING FACTORS WERE FATIGUE, LOW WX, AND CREATING A HEAVIER WORKLOAD WITH NONSTANDARD CALLOUTS.
