ACR MLG CREW LANDS WITHOUT CLRNC. UNAUTHORIZED LNDG. UNCOORD RWY OP.

Narrative

FLT WAS AN MLG JUL/SAT/92; JAN-DFW. DEPARTED JAN AT AM40; CAPT FLYING. CLRED VIA SCURRY ARR; LNDG ON RWYS 17L AND 18R AT DFW. CROSSED SCURRY AT APPROX AM40; DSNDING TO 11000 FT. ACFT WAS LEVEL AT 11000 FT ABOUT 15 DME ON THE 296 RADIAL OF SCURRY. WE WERE IN THE CLOUDS; ALTHOUGH THE WX WAS VFR BELOW WITH ABOUT A 2500 FT SCATTERED LAYER AND A BROKEN LAYER ABOUT 10000 FT. AT ABOUT 20 DME OUT OF SCURRY; THE TCASII GAVE A 'TFC' WARNING; AND THE DISPLAY SHOWED AN ACFT ABOUT 2000 FT BELOW US; CLBING. NEXT CAME A 'CLB; CLB' RA WITH THE VSI COMMANDING A HIGH RATE OF CLB. I CHOSE TO MAINTAIN LEVEL FLT; KNOWING THAT THE ACFT APCHING WAS AN OUTBOUND DEP WITH A 10000 FT ASSIGNED ALT. I TOLD THE COPLT TO RPT THAT RA TO DFW APCH CTL; AND HE DID SO. THE APCH CTLR RPTED THAT IT WAS AN ACFT LEVELING AT 10000 FT. THE RA THEN SHIFTED TO A 'MONITOR VERT SPD;' THEN IMMEDIATELY BACK TO 'CLB; CLB;' THEN TO 'CLR OF CONFLICT.' WE WERE ABOUT 32 DME; JUST ABOUT TO SLOW TO 210 KIAS WHEN THE APCH CTLR GAVE US A VECTOR AND A DSCNT TO 6000 FT; ASSIGNED US RWY 17L; AND INFORMED US IT WOULD BE A SHORT APCH. THE USUAL PROC TAKES US TO 35 DME WHERE THE ARR DICTATES A R TURN TO 350 DEGS; THEN A DSCNT CLRNC IS ISSUED. WE WERE ASKED TO EXPEDITE; AND WE DID SO. WE WERE VECTORED ONTO THE 17L LOC AND CLRED FOR THE ILS; AND THE APCH CTLR ASKED US TO CALL THE RWY IN SIGHT. WE COULD SEE THE APCH END OF THE RWY; BUT A LAYER OF CLOUDS PREVENTED OUR SEEING THE ENTIRE RWY. NEVERTHELESS; I TOLD THE COPLT TO TELL HIM WE HAD THE RWY IN SIGHT AND HE DID SO. THE CTLR THEN CLRED US FOR A VISUAL APCH TO 17L. WE LANDED AT AM50; AND AS WE TURNED OFF THE RWY; I SAW THAT THE RADIO WAS STILL ON 119.4; THE APCH CTL FREQ. WE HAD LANDED WITHOUT HAVING HEARD OR ACKNOWLEDGED THE CLRNC TO LAND! 32 YRS IN THE COCKPIT FOR ME; AND I CAN'T COME UP WITH ANY EXCUSE THAT SOUNDS EVEN HALFWAY ACCEPTABLE. PNF FAILED TO COMPLETE THE CHKLIST? SURE; BUT THAT'S NO EXCUSE. APCH CTLR FAILED TO TELL US TO CONTACT TWR? SURE; BUT THAT'S NO EXCUSE; EITHER. DISTR BECAUSE OF TCASII ENCOUNTER? MAYBE; BUT I KNOW WHAT I'D THINK IF ONE OF MY FLYING BUDDIES TRIED TO TELL ME THAT'S WHAT CAUSED HIM TO FORGET TO SWITCH TO TWR. FATIGUE? NOT A CHANCE; WE'D HAD AN ALL DAY LAYOVER AND HAD FLOWN ONLY 1 LEG PRIOR TO THIS ONE. WX? NOT REALLY. COULD IT HAPPEN TO SOMEONE ELSE? YOU BET IT COULD; AND; WITH THE TFC DENSITY CONTINUING TO INCREASE AND THE CTLR AND PLT WORKLOAD CONTINUING TO INCREASE; IT WILL HAPPEN AGAIN. I'LL CERTAINLY WORK HARD TO ENSURE IT NEVER HAPPENS TO MY CREW; BUT IS THAT ENOUGH? I DON'T KNOW.
