AN ATX PLT LANDS HIS ACFT AFTER A LONG DAY BUT FORGETS TO PUT HIS GEAR DOWN AT LUK; OH.

Narrative

ROUTINE CPR PAX PICKUP AT CINCINNATI LUNKEN ARPT. 3 PAX ALREADY ONBOARD. MY DUTY DAY STARTED AT XA30. 1ST DEP AT XC30 FROM HOME ARPT (PTK). PAX DROP OFF AT I69. THEN DEADHEAD DEP AT XE10 FOR FLORENCE; SC (FLO). DEPARTED (FLO) AT XJ25 WITH 3 PAX FOR CINCINNATI TO PICK UP ONE MORE PAX AND RETURN TO PTK. ALL OPS TO THIS POINT WERE VERY ROUTINE AND PLEASANT. HOWEVER; THIS WAS JUST THE SECOND TRIP SINCE THE ACFT HAD BEEN EXTENSIVELY RECONFIGURED WITH A NEW NAV SYS ADDED. AND THERE WERE SOME MINOR PROBS WITH THE INSTALLATION WHICH WAS A DISTR. AS WE NEARED CINCINNATI NUMEROUS TSTMS REQUIRED SOME DEV; BUT WERE NOT A FACTOR AT THE ARPT. EXTENSIVE VECTORING WAS NECESSARY TO FIT US INTO THE ARPT TFC WITH SPD REDUCTIONS THAT EVENTUALLY REQUIRED APCH FLAPS (5 DEGS) TO BE SELECTED MANY MI FROM THE ARPT. (I WAS BEING SET UP AND I DIDN'T KNOW IT.) NORMALLY; GEAR DOWN WOULD BE SELECTED FIRST IMMEDIATELY FOLLOWED BY FLAPS (5 DEGS). WHEN FINALLY CLRED FOR ILS RWY 21L AT APPROX 5 MI FINAL I SELECTED FLAPS (20 DEGS) AND COMMENCED APCH AND LNDG. WITH 20 DEG OF FLAPS WE HAD PLENTY OF DRAG AND ENOUGH TURB TO MASK THE FACT THAT THE LNDG GEAR WERE NOT EXTENDED UNTIL TOO LATE. THE WARNING HORN AND GND CONTACT WERE JUST ABOUT SIMULTANEOUS. WHAT CAN WE LEARN FROM THE INCIDENT? I THINK I WAS TIRED; TIRED MORE THAN ANYTHING ELSE; LONG DUTY DAY. THE DAY BEFORE WAS TOO. THE NAV RADIO PROB AND NEWNESS OF THE SYS REQUIRED ADDITIONAL CONCENTRATION. THE TENSION OF TSTMS IN THE TERMINAL AREA. LONG VECTORS WITH SPD RESTRS ALL REQUIRE GREATER EFFORT. 90 DEGS PLUS TEMPS ADD TO FATIGUE ALSO. I DID DO THE FINAL CHKLIST. BUT IT WAS AN EXERCISE IN ROTE; NOT REALITY. I WAS JUST TOO TIRED AND WANTED TO LAND; WHICH I DID; WHEELS UP.
