Narrative:

Visual approach den runway 7. I did not contact tower per approach control for landing clearance. Cleared to land by approach control and tower at time of touchdown. I would not have had clearance if not for professional follow-up by ZDV. Contributing factors: 1) approach control instructions to contact tower while downwind. Contact was to be made at marker. Long time period. 2) first officer, poorly flown visual approach. Required extra monitoring. 3) fatigue. Day 3 of 4 day trip. First 2 nights in old hotels. Air conditioning did not work properly. Old style construction -- both rooms noisy, minimum sleep! Fatigue was largest factor!

Title: FLC LANDS AT DEN WITHOUT PROPER LNDG CLRNC.

Narrative: VISUAL APCH DEN RWY 7. I DID NOT CONTACT TWR PER APCH CTL FOR LNDG CLRNC. CLRED TO LAND BY APCH CTL AND TWR AT TIME OF TOUCHDOWN. I WOULD NOT HAVE HAD CLRNC IF NOT FOR PROFESSIONAL FOLLOW-UP BY ZDV. CONTRIBUTING FACTORS: 1) APCH CTL INSTRUCTIONS TO CONTACT TWR WHILE DOWNWIND. CONTACT WAS TO BE MADE AT MARKER. LONG TIME PERIOD. 2) FO, POORLY FLOWN VISUAL APCH. REQUIRED EXTRA MONITORING. 3) FATIGUE. DAY 3 OF 4 DAY TRIP. FIRST 2 NIGHTS IN OLD HOTELS. AIR CONDITIONING DID NOT WORK PROPERLY.
