Narrative:

I was the right seat pilot on an IFR flight from houston inter-continental (iah) to tulsa international airport (tul) in a hawker 400 aircraft. I was typed and current as a captain on this flight as was the left seat pilot who was the PF. Tulsa approach control vectored us on a right downwind west of the field for a visual approach to runway 18L at tulsa. After descending below a high overcast I called the field in sight to the approach controller. He turned us to a 090 degree heading for the right base, cleared us for a visual approach for runway 18L and handed us off to the tower controller. Just as I was acknowledging his transmission the PF called for the first of 3 flap settings in preparation for landing. After I finished responding to the controller, I confirmed the requested flaps with the PF and put them down. I then immediately set about finishing before landing checklist as we were approximately 2 mi from the field. The second radio was tuned to ground control in preparation for its use while I was still talking to approach and when the approach controller handed us off I punched the FLIP-flop button to this radio frequency and then I tuned the other side of the radio to tower control. I neglected to reselect the other side of the radio to talk to tower as I was busy with the checklist. In so doing I was monitoring ground control on our approach and landing. After clearing the runway I reached to FLIP the radio to ground frequency and noticed it was already tuned and that I had made a mistake. The ground controller quizzed me on whether I had called the tower controller confirming I had made a major mistake. As far as I could tell no loss of separation with other aircraft occurred and no serious ramifications came of my carelessness. I feel the causes of my failure to contact tower were related to distractions in the cockpit and failure on my part to adhere to accepted standard procedures. Fatigue may have also played a role.

Title: HS125 CREW LANDS AT TUL WITHOUT CLRNC AND OFF LCL CTL FREQ.

Narrative: I WAS THE R SEAT PLT ON AN IFR FLT FROM HOUSTON INTER-CONTINENTAL (IAH) TO TULSA INTL ARPT (TUL) IN A HAWKER 400 ACFT. I WAS TYPED AND CURRENT AS A CAPT ON THIS FLT AS WAS THE L SEAT PLT WHO WAS THE PF. TULSA APCH CTL VECTORED US ON A R DOWNWIND W OF THE FIELD FOR A VISUAL APCH TO RWY 18L AT TULSA. AFTER DSNDING BELOW A HIGH OVCST I CALLED THE FIELD IN SIGHT TO THE APCH CTLR. HE TURNED US TO A 090 DEG HDG FOR THE R BASE, CLRED US FOR A VISUAL APCH FOR RWY 18L AND HANDED US OFF TO THE TWR CTLR. JUST AS I WAS ACKNOWLEDGING HIS XMISSION THE PF CALLED FOR THE FIRST OF 3 FLAP SETTINGS IN PREPARATION FOR LNDG. AFTER I FINISHED RESPONDING TO THE CTLR, I CONFIRMED THE REQUESTED FLAPS WITH THE PF AND PUT THEM DOWN. I THEN IMMEDIATELY SET ABOUT FINISHING BEFORE LNDG CHKLIST AS WE WERE APPROX 2 MI FROM THE FIELD. THE SECOND RADIO WAS TUNED TO GND CTL IN PREPARATION FOR ITS USE WHILE I WAS STILL TALKING TO APCH AND WHEN THE APCH CTLR HANDED US OFF I PUNCHED THE FLIP-FLOP BUTTON TO THIS RADIO FREQ AND THEN I TUNED THE OTHER SIDE OF THE RADIO TO TWR CTL. I NEGLECTED TO RESELECT THE OTHER SIDE OF THE RADIO TO TALK TO TWR AS I WAS BUSY WITH THE CHKLIST. IN SO DOING I WAS MONITORING GND CTL ON OUR APCH AND LNDG. AFTER CLRING THE RWY I REACHED TO FLIP THE RADIO TO GND FREQ AND NOTICED IT WAS ALREADY TUNED AND THAT I HAD MADE A MISTAKE. THE GND CTLR QUIZZED ME ON WHETHER I HAD CALLED THE TWR CTLR CONFIRMING I HAD MADE A MAJOR MISTAKE. AS FAR AS I COULD TELL NO LOSS OF SEPARATION WITH OTHER ACFT OCCURRED AND NO SERIOUS RAMIFICATIONS CAME OF MY CARELESSNESS. I FEEL THE CAUSES OF MY FAILURE TO CONTACT TWR WERE RELATED TO DISTRACTIONS IN THE COCKPIT AND FAILURE ON MY PART TO ADHERE TO ACCEPTED STANDARD PROCS. FATIGUE MAY HAVE ALSO PLAYED A ROLE.
