Narrative:

Gave clearance to land on a closed runway. Traffic was very light. I was assigned to local control at beginning of shift. Five mins after signing on, local port authority informs of closure of runway 8, due to painting of hold lines at intxns right and west. This closing of the runways has been going on for over two months, and always during daytime hours (typically XA00-XE00, XM00-XP00 daily). I acknowledged the runway closure, coordinated with approach control, and put up visual aids. In the next ten mins, I only had 2-3 arrival (very light traffic), one was an ATR 72, who normally parks on north side of airport. It was at this time that I offered runway 8 (closed) to the aircraft X thinking of expediting him to his gate, totally forgetting the runway closure. I did scan the runway, there were no vehicles/personnel, since the painting was being done on the txwys. I realized my mistake too late, when the aircraft was on rollout. I had come to work feeling sick, with the flu. I decided to come in to work like this, due to the current low staffing situation our facility is going through. This was a mistake. My concentration was definitely affected by my illness -- I was feeling a bit dizzy, bit of fever etc -- generally felt spaced-out, this contributed to my lack of concentration and the eventual operational error.

Title: SJU LC ISSUES LNDG CLRNC TO AT72 ON CLOSED RWY, REMEMBERING CLOSURE DURING ROLLOUT.

Narrative: GAVE CLRNC TO LAND ON A CLOSED RWY. TFC WAS VERY LIGHT. I WAS ASSIGNED TO LOCAL CTL AT BEGINNING OF SHIFT. FIVE MINS AFTER SIGNING ON, LOCAL PORT AUTHORITY INFORMS OF CLOSURE OF RWY 8, DUE TO PAINTING OF HOLD LINES AT INTXNS R AND W. THIS CLOSING OF THE RWYS HAS BEEN GOING ON FOR OVER TWO MONTHS, AND ALWAYS DURING DAYTIME HRS (TYPICALLY XA00-XE00, XM00-XP00 DAILY). I ACKNOWLEDGED THE RWY CLOSURE, COORDINATED WITH APCH CTL, AND PUT UP VISUAL AIDS. IN THE NEXT TEN MINS, I ONLY HAD 2-3 ARR (VERY LIGHT TFC), ONE WAS AN ATR 72, WHO NORMALLY PARKS ON N SIDE OF ARPT. IT WAS AT THIS TIME THAT I OFFERED RWY 8 (CLOSED) TO THE ACFT X THINKING OF EXPEDITING HIM TO HIS GATE, TOTALLY FORGETTING THE RWY CLOSURE. I DID SCAN THE RWY, THERE WERE NO VEHICLES/PERSONNEL, SINCE THE PAINTING WAS BEING DONE ON THE TXWYS. I REALIZED MY MISTAKE TOO LATE, WHEN THE ACFT WAS ON ROLLOUT. I HAD COME TO WORK FEELING SICK, WITH THE FLU. I DECIDED TO COME IN TO WORK LIKE THIS, DUE TO THE CURRENT LOW STAFFING SIT OUR FAC IS GOING THROUGH. THIS WAS A MISTAKE. MY CONCENTRATION WAS DEFINITELY AFFECTED BY MY ILLNESS -- I WAS FEELING A BIT DIZZY, BIT OF FEVER ETC -- GENERALLY FELT SPACED-OUT, THIS CONTRIBUTED TO MY LACK OF CONCENTRATION AND THE EVENTUAL OPERATIONAL ERROR.
