ACFT EQUIP PROB. NOSE GEAR INDICATOR AND NOSE GEAR COLLAPSED ON LNDG.

Narrative

IN MID-MARCH I HAD A HARD LNDG AT TULSA INTL ARPT. REPAIRS CALLED FOR AN ENG TEAR DOWN; REPLACEMENT OF THE PROP; A NEW NOSE RIM; TIRE; AND MINOR REPAIRS IN THE WHEELWELL. THE ENG WAS GIVEN A TOP OVERHAUL AS WELL. ON JUN/XX/96; FBO FELT THAT THE REPAIRS AND ADJUSTMENTS WERE COMPLETE AND THE PLANE COULD BE TESTED TO CHK OIL TEMP AND BREAK-IN BEFORE RETURNING TO THE CHICAGO AREA. THE FLT WAS NORMAL AND AFTER APPROX 45 MINS; I RETURNED TO TULSA INTL. I WAS CLRED FOR A STRAIGHT-IN APCH TO RWY 18R AND ABOUT 5 MI OUT EXTENDED THE GEAR. THE MAINS CAME DOWN; BUT I DID NOT RECEIVE A GREEN LIGHT FOR THE NOSEWHEEL. I EXTENDED THE GEAR AGAIN AND STILL DID NOT RECEIVE A GREEN LIGHT. I CHKED THE LIGHT AND FUSES WHICH APPEARED NORMAL AND ADVISED THE TWR OF THE PROB. THEY CLRED ME FOR A LOW PASS IN ORDER TO CHK THE GEAR WITH FIELD GLASSES. THE TWR RPTED THAT THE GEAR APPEARED TO BE DOWN. I WAS CLRED TO PATTERN ALT AND TOLD TO TAKE WHATEVER ACTION I FELT NECESSARY. I RETRACTED THE GEAR AND EXTENDED IT AGAIN; STILL WITHOUT RECEIVING A GREEN LIGHT. FOLLOWING THE EMER PROCS; I LEFT THE GEAR DOWN LEVER IN THE DOWN POS; EXTENDED THE EMER PUMP AND PUMPED APPROX 60 TIMES UNTIL THE HANDLE COULD NOT BE WORKED; LOCKED IT BACK INTO POS AND ADVISED THE TWR I WAS READY TO LAND. THE TWR CLRED ME TO LAND ON RWY 18L. I SLOWED THE PLANE TO APPROX 70 KTS; TOUCHED DOWN WITH NO BOUNCE AND KEPT THE WT OFF THE NOSE AS LONG AS POSSIBLE. THE NOSEWHEEL SETTLED GENTLY TO THE GND; ROLLED 5 OR 10 FT AND COLLAPSED. IN REMOVING THE PLANE FROM THE RWY; THE NOSE WAS RAISED OFF THE GND AND I TRIED PUMPING THE GEAR DOWN 3 TIMES. THE GEAR COLLAPSED TWICE MORE. ON THE THIRD ATTEMPT A FIREMAN KICKED THE FRONT TIRE; THE GEAR LOCKED AND THE GREEN LIGHT CAME ON. THE PLANE WAS TOWED TO THE HANGAR WITH NO FURTHER PROBS.
