Narrative:

After departing abq for our 2ND leg of the day (from jvl, wi) we were on an IFR clearance to flg. Center handed us off to tower. We were approaching from the sse. Normal operations called for a right down wind to runway 3. However, tower said left downwind. I asked PNF (chief pilot) to confirm. They indicated left downwind. I asked if over the top to enter was ok. They advised yes, report left base. On left downwind, we overheard tower talking to a flight check aircraft. They were on both tower and ground as flight check was taxiing out. PNF called tower, said we were on base and could cancel IFR if it would expedite for other aircraft. At this point, I was checking landing checklist, cabin altitude, etc. Chief pilot indicated we were clear to land. I feel we were as well. However, once on runway, tower said we were overhead. We advised we were on runway and thought we were cleared to land. He said negative. We were on a drop- off, and didn't have time to call tower. However, they never asked us to. Still I thought we were cleared to land. Several factors here caused confusion. 1) the cancellation of IFR caused distraction to tower controller. 2) 1 controller in cabin attendant. 3) PNF canceling without consulting PF, thus shifting on duties in cabin, ie, cabin altitude, etc. Myself for not listening. We had been on duty about 12 hours and flown about 7 hours thus far at the time.

Title: UNAUTH LNDG.

Narrative: AFTER DEPARTING ABQ FOR OUR 2ND LEG OF THE DAY (FROM JVL, WI) WE WERE ON AN IFR CLRNC TO FLG. CTR HANDED US OFF TO TWR. WE WERE APCHING FROM THE SSE. NORMAL OPS CALLED FOR A R DOWN WIND TO RWY 3. HOWEVER, TWR SAID L DOWNWIND. I ASKED PNF (CHIEF PLT) TO CONFIRM. THEY INDICATED L DOWNWIND. I ASKED IF OVER THE TOP TO ENTER WAS OK. THEY ADVISED YES, RPT L BASE. ON L DOWNWIND, WE OVERHEARD TWR TALKING TO A FLT CHK ACFT. THEY WERE ON BOTH TWR AND GND AS FLT CHK WAS TAXIING OUT. PNF CALLED TWR, SAID WE WERE ON BASE AND COULD CANCEL IFR IF IT WOULD EXPEDITE FOR OTHER ACFT. AT THIS POINT, I WAS CHKING LNDG CHKLIST, CABIN ALT, ETC. CHIEF PLT INDICATED WE WERE CLR TO LAND. I FEEL WE WERE AS WELL. HOWEVER, ONCE ON RWY, TWR SAID WE WERE OVERHEAD. WE ADVISED WE WERE ON RWY AND THOUGHT WE WERE CLRED TO LAND. HE SAID NEGATIVE. WE WERE ON A DROP- OFF, AND DIDN'T HAVE TIME TO CALL TWR. HOWEVER, THEY NEVER ASKED US TO. STILL I THOUGHT WE WERE CLRED TO LAND. SEVERAL FACTORS HERE CAUSED CONFUSION. 1) THE CANCELLATION OF IFR CAUSED DISTR TO TWR CTLR. 2) 1 CTLR IN CAB. 3) PNF CANCELING WITHOUT CONSULTING PF, THUS SHIFTING ON DUTIES IN CABIN, IE, CABIN ALT, ETC. MYSELF FOR NOT LISTENING. WE HAD BEEN ON DUTY ABOUT 12 HRS AND FLOWN ABOUT 7 HRS THUS FAR AT THE TIME.
