FLC OF AN LTT CALLED FOR CFR GND EQUIP STANDBY DURING LNDG DUE TO INTERMITTENT GEAR LIGHT INDICATION.

Narrative

DEPARTED MLB; FL TO MCO; FL; IN THE MIDDLE OF A 15 1/2 HR DUTY DAY. THE TOTAL DURATION OF THIS FLT IS 20 MINS OR LESS. UPON CLBOUT; AFTER TKOF WE WERE PERFORMING CLB CHKLIST; I WAS THE PF; WHEN WE NOTICED WE STILL HAD A RED; R GEAR LIGHT AND WERE DISCUSSING IT WHEN TWR CALLED AND STATED IT APPEARED WE STILL HAD A GEAR DOWN. WE FOLLOWED PROC TO RECYCLE THE GEAR AND OBSERVED NORMAL INDICATIONS FOR INTRANSIT; DOWN AND LOCK GREEN LIGHTS AND ON UP CYCLE NORMAL INDICATIONS AGAIN; TWR ASKED OUR INTENTIONS AND WE CONFERRED AND ELECTED TO CONTINUE AND RUN OUR CHKLIST; NORMAL AND ABNORMAL. AS WE WERE TROUBLE- SHOOTING AND DOING CHKLIST THE R MAIN GEAR INDICATOR LIGHT WOULD BE OUT; THEN COME ON RED; THEN GO TO GREEN AND THEN OUT AND; AGAIN CYCLE; OUR CHKLIST DID NOT ADDRESS THIS AND WE WERE BY THIS TIME LESS THAN 10 MI FROM MCO AND ELECTED TO EXTEND THE GEAR DOWN; AGAIN RECEIVED ALL NORMAL INDICATIONS AND ALL DOWN AND LOCK LIGHTS. WE NOTIFIED MCO APCH; WHICH WE WERE TALKING TO BY THIS POINT THAT OUR SPD WOULD BE ONLY 170 KTS DUE TO OUR GEAR EXTENSION FROM THE LIGHT INDICATION. APCH CLRED US FOR VISUAL AND TURNED US OVER TO TWR AS WE INDICATED ALL WAS FINE NO EMER EXISTED. TWR CLRED US TO LAND AND WE ASKED TWR IF THEY COULD VISUALLY CONFIRM OUR GEAR WAS DOWN AS IT WAS INDICATING AND THEY SAID YES IT WAS; DO YOU WANT ASSISTANCE? I DECIDED TO ASK TWR IF THE EQUIP COULD STAND BY BUT WE HAD NO EMER INDICATED; I JUST WANT TO BE ON THE SAFE SIDE. THE LNDG; TAXI; ALL WENT NORMAL. MAINT DETERMINED THAT AN UP LIMIT SWITCH WAS ONLY WORKING INTERMITTENTLY AND CHANGED IT. I BELIEVE THIS FLT AND THE ABNORMAL SIT WAS HANDLED PROFESSIONALLY AND IN TOTAL SAFETY. I HOPE THE DECISIONS MADE ARE NEVER IN QUESTION IN REGARD TO CONTINUING A FLT; BUT IF IT IS; THAT THE FACTS AND CLOSE PROX AND VERY SHORT DURATION PROVES THE SAFEST DECISIONS AND RIGHT DECISIONS WERE MADE TO THE BEST ARPT IN POINT OF TIME.
