Narrative:
During ILS approach in IMC, icing conditions, aircraft was cleared for ILS approach by approach control. Either both crew members missed the handoff to tower or a handoff was never given, but we continued the approach and landed. Just prior to exiting the runway, we noticed we were still on approach control frequency. We had landed without contacting the tower. We then switched to tower and were told to taxi to the ramp. Both crew members were fatigued, and it was a high workload period, with the approach and air foil anti-icing procedures. Supplemental information from acn 397062: recalling the approach, I cannot remember if instructed to contact tower. Other factors affecting the flight were high workload due to icing conditions on approach and crew fatigue.

Title: MLG ACR FLC CONDUCTED AN IFR APCH AND LANDED WITHOUT TWR CLRNC. FLC CITES FATIGUE AND OTHER COCKPIT ACTIONS AS CONTRIBUTING FACTORS.
Narrative: DURING ILS APCH IN IMC, ICING CONDITIONS, ACFT WAS CLRED FOR ILS APCH BY APCH CTL. EITHER BOTH CREW MEMBERS MISSED THE HDOF TO TWR OR A HDOF WAS NEVER GIVEN, BUT WE CONTINUED THE APCH AND LANDED. JUST PRIOR TO EXITING THE RWY, WE NOTICED WE WERE STILL ON APCH CTL FREQ. WE HAD LANDED WITHOUT CONTACTING THE TWR. WE THEN SWITCHED TO TWR AND WERE TOLD TO TAXI TO THE RAMP. BOTH CREW MEMBERS WERE FATIGUED, AND IT WAS A HIGH WORKLOAD PERIOD, WITH THE APCH AND AIR FOIL ANTI-ICING PROCS. SUPPLEMENTAL INFO FROM ACN 397062: RECALLING THE APCH, I CANNOT REMEMBER IF INSTRUCTED TO CONTACT TWR. OTHER FACTORS AFFECTING THE FLT WERE HIGH WORKLOAD DUE TO ICING CONDITIONS ON APCH AND CREW FATIGUE.
