PA46 PILOT USES MANUAL GEAR EXTENSION METHOD AFTER GEAR FAILS TO EXTEND NORMALLY. THE NOSE GEAR DOES NOT INDICATE SAFE UNTIL THE ACFT IS ON FINAL APPROACH.

Narrative

I WAS ON FINAL APCH INTO ZZZ AND WHEN I ACTIVATED THE GEAR HANDLE TO EXTEND THE GEAR. THERE WAS NO GEAR INDICATOR LIGHTS; NOR DID I HEAR THE NORMAL GEAR ACTIVATION SOUNDS FROM THE HYD SYS. I RE-ACTIVATED THE GEAR HANDLE WITH NO SUCCESS; AND THEN FOLLOWED THE EMER GEAR EXTENSION PROCS; WHICH IN THE MALIBU IS A MECHANICAL EXTENSION HANDLE THAT DUMPS THE HYD PRESSURE AND ALLOWS THE GEAR TO FREE FALL. THE MAIN GEAR THEN EXTENDED; BUT THE NOSE GEAR LIGHT DID NOT ILLUMINATE; INDICATING THAT IT DID NOT EXTEND. I CALLED THE TWR AND INFORMED THEM OF MY PROB AND REQUESTED A LOW APCH TO DETERMINE IF THEY COULD SEE IF THE GEAR HAD EXTENDED AT ALL. ON THE LOW APCH; BOTH THE TWR AND A COUPLE OF ACFT ON THE GND STATED THAT IT APPEARED THAT THE NOSE GEAR HAD EXTENDED; BUT THAT THE NOSEWHEEL HAD NOT ROTATED TO ITS FORE AND AFT POS; BUT WAS TURNED 90 DEGS. I THEN INFORMED THE TWR THAT I WANTED TO LEAVE THE IMMEDIATE AREA IN ORDER TO FURTHER DIAGNOSE THE PROB AND RECHK THE EMER PROCS. I PERFORMED ALL OF THE PROCS AGAIN BUT THE NOSEWHEEL GEAR LIGHT CONTINUED TO FAIL TO ILLUMINATE. I THEN INFORMED THE TWR OF THIS FACT AND THAT I WOULD HAVE TO DECLARE AN EMER AND LAND WITH THE NOSEWHEEL PERPENDICULAR TO THE RTE OF FLT. THE EMER EQUIP WAS NOTIFIED AND I WAS THEN CLRED TO LAND. ON SHORT FINAL; THE NOSE GEAR ILLUMINATED; AND I COULD TELL BY THE REDUCTION IN WIND NOISE THAT THE WHEEL HAD ROTATED TO ITS PROPER FORE AND AFT POS. THE SUBSEQUENT LNDG WAS UNEVENTFUL; AND I TAXIED TO THE HANGAR WITHOUT FURTHER PROBS. I WAS MET BY THE EMER PERSONNEL AND GAVE THEM MY NAME; ADDRESS; AND TELEPHONE NUMBER; AFTER WHICH I SECURED THE PLANE AND IT WAS TOWED TO THE HANGAR FOR FURTHER INSPECTION AND MAINT. CALLBACK CONVERION WITH RPTR REVEALED THE FOLLOWING INFO: HE WAS NOT FAMILIAR WITH THE REQUIREMENT TO SLOW BELOW 90 KTS FOR THE NOSE GEAR TO INDICATE SAFE AFTER A MANUAL EXTENSION. POST REVEALED THAT THE LANDING GEAR CIRCUIT BREAKER HAD FAILED CAUSING THE INITIAL GEAR MALFUNCTION. THIS FAILURE DID NOT CAUSE THE CB TO POP OUT.
