SMT WITH GEAR INDICATION DIFFICULTIES LANDS RSW SAFELY.

Narrative

COMING INTO FT MYERS TO LAND; UPON SELECTING GEAR DOWN; I GOT A RED LIGHT AND NO L MAIN GEAR LIGHT. MY COPLT RECYCLED THE GEAR GETTING THE SAME INDICATION. HE THEN RECYCLED THE GEAR 3 MORE TIMES. I THEN GAVE THE AIRPLANE TO MY COPLT AND I RECYCLED THE GEAR TWICE; RECEIVING THE SAME INDICATION. WE THEN RAN THE ABNORMAL CHKLIST FOR GEAR. AFTER THIS; WE WERE TURNED OVER TO THE TWR AT FT MYERS AND I ASKED TO DO A LOW APCH AND SEE IF THEY COULD TELL IF MY L GEAR LOOKED DOWN AND LOCKED AND MY GEAR DOORS WERE CLOSED. THERE WERE APPROX 5 OR 6 SVC AND EMER VEHICLES LOOKING AS WE FLEW DOWN LOW OVER THE TXWY AT 200 FT. THE VEHICLES RPTED THAT OUR GEAR LOOKED DOWN AND LOCKED. AT THIS TIME WE STILL HAD A RED LIGHT AND NO L GEAR LIGHT. THE TWR ASKED US TO STATE OUR INTENTIONS AND WE STATED WE WERE GOING TO LAND. THE RESCUE VEHICLES WERE WAITING FOR US WHEN WE LANDED. WE LANDED WITH NO PROBS. THERE WAS NO OTHER TFC AT THE ARPT AT THAT TIME; I WAS SUSPECTING A CIRCUIT BOARD PROB CAUSING ERRONEOUS LIGHTS; WHICH IS WHAT RAYTHEON HAD TOLD ME MIGHT BE CAUSING THE PROB. WE TAXIED ONTO THE RAMP. UPON INSPECTION OF THE GEAR; IT WAS FOUND TO NOT BE DOWN AND LOCKED. THE ONLY THING I MIGHT HAVE DONE DIFFERENT WOULD HAVE BEEN TO DECLARE AN EMER; BUT THE RESCUE VEHICLES WERE ALREADY OUT. I ALSO SHOULD HAVE JUST STOPPED THE AIRPLANE ON THE RWY AND CHKED THE GEAR; AT WHICH TIME I COULD HAVE HAD IT TOWED IN. THE REASON I DIDN'T WAS BECAUSE I DID NOT THINK IT WAS A GEAR PROB BUT RATHER A LIGHT PROB CAUSED BY A BAD CIRCUIT BOARD.
