UNAUTH LNDG. CLRNC LNDG MAY NOT HAVE BEEN RECEIVED IN AN ACR NIGHT OP.

Narrative

I FLY NIGHT CARGO OPS IN DC9 ACFT FOR XYZ AIRLINES. I FLY REGULARLY INTO ICT. ON MANY OCCASIONS APCH; TWR; GND AND THE FLT DATA POS; ARE COMBINED AND WORKED BY THE SAME PERSON. OUR ARR IS EITHER LATE AT NIGHT; OR VERY EARLY IN THE MORNING. ON JAN/XX/94; I FLEW AS FO ON FLT FROM WILMINGTON; OH; TO WICHITA; KS; INTO ICT ARPT. BOTH THE CAPT AND I HAD BEEN ON DUTY ABOUT 9 HRS SINCE XA00 EDT; AS WE NEARED ICT ARPT AND WERE TOLD TO CONTACT ICT APCH ON 134.0. I WAS WORKING THE RADIOS AND THE CAPT WAS FLYING THIS PARTICULAR LEG. I CONTACTED ICT APCH AND RECEIVED NO ANSWER. I RECONTACTED APCH A SECOND TIME AND THE CTLR ANSWERED; INSTRUCTING ME TO RPT THE FIELD IN SIGHT FOR THE VISUAL TO RWY 19R. AT ABOUT 6 MI OUT THE CAPT TOLD ME HE HAD THE RWY SO I NOTIFIED THE CTLR AND HE CLRED US FOR THE VISUAL TO RWY 19R. WE WERE BOTH VERY TIRED; AS WE WERE FINISHING UP A VERY DIFFICULT LINE OF FLYING THROUGHOUT THE WK. AFTER LNDG AND ROLLOUT; THE CAPT AND I BOTH LOOKED DOWN AND SAW THAT THE RADIO WAS STILL SET ON 134.0. NEITHER THE CAPT NOR I COULD REMEMBER WHETHER WE WERE SWITCHED OVER TO TWR; 118.2; OR CLRED TO LAND BY THE APCH CTLR; OR WHETHER WE LANDED WITHOUT CLRNC. AFTER WE PULLED OFF THE RWY; I CONTACTED GND ON 121.9; AND HE INSTRUCTED US TO TAXI TO PARKING; AS USUAL. THERE WAS NO MENTION OF LNDG WITHOUT CLRNC BY GND; US; OR THE CLRNC DELIVERY PERSON OF THE NEXT CLRNC OUTBOUND. I AM NOT SURE WHETHER WE LANDED WITHOUT CLRNC OR WERE CLRED BY THE APCH CTLR TO LAND; AS HAPPENS MANY OTHER NIGHTS. AGAIN; NOTHING WAS SAID; BUT I'M JUST NOT SURE WHETHER WE HAD CLRNC TO LAND OR NOT.
