Narrative:

On a ferry leg with no passenger, I was letting my first officer fly to allow him to gain experience. I was providing a fair amount of prompting to keep him aware of tracking, etc, on the approach. The approach ended with me picking up the approach lights at minimums. At that time I made a mental check that we showed 3 green landing gear lights, runway was clear, checklist complete and cleared to land, as I always do. We landed and rolled to a stop a bit beyond a taxiway, so I requested a 180 degree turn to taxi back, which was approved. After we switched to ground control on the taxiway, we were asked by the ground controller if we were aware that we had just landed without a landing clearance. I was not aware of that, nor was my first officer. The controllers at psm do a great job and I am not going to argue with them. Apparently when switched to tower by approach control, I made the switch but was distraction by something that required my attention and forgot to make the call to psm tower. After landing, both my first officer and myself believed we had made the call. I believe that considering the WX and time of day, I should have foregone the flight instruction type environment for a safer more normal atmosphere which was without increased workload. Meaning I should have been flying the approach instead of providing the prompting while trying to perform the PNF duties. Another contributing factor is the fact that I was becoming sick with the flu. After landing, I was light headed, which was caused by the flu. At any rate, both my first officer and myself thought we had heard the controller's usual 'check wheels down, cleared to land.'

Title: AN ATX FERRY FLT LANDS WITHOUT CLRNC AT PSM, NH.

Narrative: ON A FERRY LEG WITH NO PAX, I WAS LETTING MY FO FLY TO ALLOW HIM TO GAIN EXPERIENCE. I WAS PROVIDING A FAIR AMOUNT OF PROMPTING TO KEEP HIM AWARE OF TRACKING, ETC, ON THE APCH. THE APCH ENDED WITH ME PICKING UP THE APCH LIGHTS AT MINIMUMS. AT THAT TIME I MADE A MENTAL CHK THAT WE SHOWED 3 GREEN LNDG GEAR LIGHTS, RWY WAS CLR, CHKLIST COMPLETE AND CLRED TO LAND, AS I ALWAYS DO. WE LANDED AND ROLLED TO A STOP A BIT BEYOND A TXWY, SO I REQUESTED A 180 DEG TURN TO TAXI BACK, WHICH WAS APPROVED. AFTER WE SWITCHED TO GND CTL ON THE TXWY, WE WERE ASKED BY THE GND CTLR IF WE WERE AWARE THAT WE HAD JUST LANDED WITHOUT A LNDG CLRNC. I WAS NOT AWARE OF THAT, NOR WAS MY FO. THE CTLRS AT PSM DO A GREAT JOB AND I AM NOT GOING TO ARGUE WITH THEM. APPARENTLY WHEN SWITCHED TO TWR BY APCH CTL, I MADE THE SWITCH BUT WAS DISTR BY SOMETHING THAT REQUIRED MY ATTN AND FORGOT TO MAKE THE CALL TO PSM TWR. AFTER LNDG, BOTH MY FO AND MYSELF BELIEVED WE HAD MADE THE CALL. I BELIEVE THAT CONSIDERING THE WX AND TIME OF DAY, I SHOULD HAVE FOREGONE THE FLT INSTRUCTION TYPE ENVIRONMENT FOR A SAFER MORE NORMAL ATMOSPHERE WHICH WAS WITHOUT INCREASED WORKLOAD. MEANING I SHOULD HAVE BEEN FLYING THE APCH INSTEAD OF PROVIDING THE PROMPTING WHILE TRYING TO PERFORM THE PNF DUTIES. ANOTHER CONTRIBUTING FACTOR IS THE FACT THAT I WAS BECOMING SICK WITH THE FLU. AFTER LNDG, I WAS LIGHT HEADED, WHICH WAS CAUSED BY THE FLU. AT ANY RATE, BOTH MY FO AND MYSELF THOUGHT WE HAD HEARD THE CTLR'S USUAL 'CHK WHEELS DOWN, CLRED TO LAND.'
