Narrative

SMA X APCHING WESTCHESTER COUNTY ARPT; WAS HANDED OFF FROM APCH CTL TO THE LCL CTLR WHO INSTRUCTED ME TO ENTER A L DOWNWIND FOR RWY 29. THIS I DID AND RPTED ON L DOWNWIND. WHEN I WAS APPROX ABEAM THE NUMBERS FOR RWY 29; THE CTLR SAID I WAS #2 FOR LNDG ON RWY 29 WITH AN SMA Y ON FINAL (NO OTHER TFC WAS RPTED LNDG ON RWY 34; WHICH WAS ALSO IN USE). I RPTED THE TFC IN SIGHT AND STARTED A L BASE. THE SMA AHEAD OF ME LANDED. WHEN I WAS ON FINAL; THE CTLR INSTRUCTED SMA Y TO TAXI INTO POS AND HOLD ON RWY 29. THIS IS NOT UNUSUAL FOR THIS RWY SINCE THERE IS A LONG DISPLACED THRESHOLD OF 1287 FT. I HAD PASSED OVER THE HOLDING SMA Y AND WAS ABOUT TO LAND WHEN THE CTLR CLRED THE SMA Y FOR TKOF ON RWY 29. I HASTILY INFORMED THE CTLR THAT I WAS JUST ABOUT TO TOUCH DOWN. SHE THEN ASKED ME TO STATE MY POS. I SAID AGAIN THAT I WAS ABOUT TO TOUCH DOWN. SHE THEN INSTRUCTED ME TO LAND AND TOLD THE OTHER ACFT TO STOP HIS TKOF ROLL AND RETURN TO POS. I LANDED WITHOUT INCIDENT. LOOKING BACK; I REALIZED I HAD NOT RECEIVED A LNDG CLRNC. SOMETIMES CLRNCS ARE GIVEN AT THE LAST MIN; SO I WILL ASK IF I'M CLRED WHEN ON FINAL AND HAVEN'T YET RECEIVED CLRNC. I WAS CONCERNED WITH THE LNDG AND WITH CHKING FOR TFC ON RWY 34 APCH AND ASSUMED THE CTLR KNEW WHERE I WAS.
