Narrative:

We were on radar vectors to intercept ILS 3L localizer at 3000'. After being cleared for approach, we xed the OM and selected gear down. The main gear indicators indicated in transit followed by 2 green lights. The nose in transit light did not illuminate nor did the green indicator, so we cycled gear twice. We requested a missed approach. Given radar vectors for another approach we went through the emergency checklist for improper landing gear indicators. After following the checklist we concluded that, in fact, the nose gear was down. We requested a low approach to see if the tower could see the nose gear. He indicated that, in fact, the nose gear was down. For precautionary measures we requested cancellation of IFR. We had the F/a prepare the cabin for an emergency landing and the requested radar vectors for another approach. We shot the approach and had an uneventful landing. We did not have a problem taxiing to the ramp under own power.

Title: COMMUTER FLC ON APCH TO MKG EXPERIENCES FAULTY NOSE GEAR POSITION INDICATOR.

Narrative: WE WERE ON RADAR VECTORS TO INTERCEPT ILS 3L LOC AT 3000'. AFTER BEING CLRED FOR APCH, WE XED THE OM AND SELECTED GEAR DOWN. THE MAIN GEAR INDICATORS INDICATED IN TRANSIT FOLLOWED BY 2 GREEN LIGHTS. THE NOSE IN TRANSIT LIGHT DID NOT ILLUMINATE NOR DID THE GREEN INDICATOR, SO WE CYCLED GEAR TWICE. WE REQUESTED A MISSED APCH. GIVEN RADAR VECTORS FOR ANOTHER APCH WE WENT THROUGH THE EMER CHKLIST FOR IMPROPER LNDG GEAR INDICATORS. AFTER FOLLOWING THE CHKLIST WE CONCLUDED THAT, IN FACT, THE NOSE GEAR WAS DOWN. WE REQUESTED A LOW APCH TO SEE IF THE TWR COULD SEE THE NOSE GEAR. HE INDICATED THAT, IN FACT, THE NOSE GEAR WAS DOWN. FOR PRECAUTIONARY MEASURES WE REQUESTED CANCELLATION OF IFR. WE HAD THE F/A PREPARE THE CABIN FOR AN EMER LNDG AND THE REQUESTED RADAR VECTORS FOR ANOTHER APCH. WE SHOT THE APCH AND HAD AN UNEVENTFUL LNDG. WE DID NOT HAVE A PROB TAXIING TO THE RAMP UNDER OWN PWR.
