CL65 NOSE GEAR FAILS TO EXTEND DURING APCH TO ZZZ. FLT CREW ELECTS TO LAND AND EVACS ACFT ON RWY WITHOUT INJURIES.

Narrative

FLT XXXX WAS NORMAL UP TO THE POINT WHERE I (PF) ASKED FOR 'GEAR DOWN; BEFORE LNDG CHK.' AT THAT TIME THE CAPT (PNF) HIT THE HI/LOW CHIME AND SELECTED THE GEAR DOWN. I HEARD THE MAIN WHEELS GO DOWN AND LOCK; AND THE NOSE GEAR DOOR OPEN. A FEW SECONDS LATER WE HEARD A TRIPLE CHIME AND 'GEAR DISAGREE.' THE NOSE GEAR POS INDICATOR WAS SHOWING A RED LATCHED BOX. I WAS TURNING BASE TO FINAL; WITH THE RWY OF LNDG IN SIGHT WHEN WE HEARD THE WARNING. THE CAPT NOTIFIED THE TWR WE HAD A GEAR INDICATION PROB AND NEEDED SOME TIME. THE TWR CTLR SUGGESTED A 360 DEG TURN; SO AS PER ATC INSTRUCTIONS WE TURNED WESTWARD. THE CAPT DELEGATED FLYING AND RADIOS TO ME WHILE HE ACCOMPLISHED THE QRH AND BRIEFED THE FLT ATTENDANT. THE FUEL AT THIS TIME WAS APPROX 2700 LBS -- WE WERE BOTH VERY MINDFUL OF OUR FUEL STATUS AND CONTINUED TO MONITOR IT THROUGHOUT THE EVENTS THAT FOLLOWED. TWR SWITCHED ME BACK TO APCH WHERE THEY GAVE MULTIPLE VECTORS AND NOTIFIED ME OF TFC IN THE AREA. AT THIS POINT WE DECLARED AN EMER. AS THE CAPT COMPLETED THE QRH; ATC ASKED IF THEY COULD ARRANGE A FLY-BY FOR SOMEONE TO SEE IF THE NOSE GEAR WAS DOWN. I AGREED TO THE SUGGESTION. ATC VECTORED US AROUND AND HAD ME CHANGE ALT FOR COMPANY TO FLY BELOW US. ATC CALLED OUT COMPANY TFC AHEAD OF US PARALLELING OUR COURSE. I HAD THEM IN SIGHT AT ALL TIMES. AS COMPANY FLEW BELOW US; THEY CONFIRMED THAT THE NOSE GEAR WAS NOT DOWN. AT THIS POINT THE CAPT WAS DONE WITH THE EMER PROCS; AND WE REVIEWED THE PAX EVAC PROC. WE HAD 45 MINS OF FUEL LEFT AND ASKED ATC FOR A VECTOR TO THE NEAREST RWY AT ZZZ. THEY GAVE US A HEADING. AS SOON AS WE HAD THE ARPT IN SIGHT; THEY CLRED US FOR THE VISUAL APCH. THE CAPT ASSUMED THE FLT CTLS FOR THE FINAL APCH. THE CAPT DID AN INCREDIBLE APCH AND LNDG; ESPECIALLY IN THE GUSTY CONDITIONS. AFTER THE MAINS TOUCHED; THE CAPT GENTLY LET THE NOSE DOWN ON THE RWY. WE SLID TO A CTLED STOP ON THE RWY (ALMOST ON THE CTRLINE). WE EVACED THE PAX AND ONCE WE SECURED THE ACFT; LEFT TO ASSIST THE FLT ATTENDANT. AT THAT TIME; WE DIDN'T KNOW WHY THE NOSE GEAR HAD NOT COME DOWN; THE COMPANY IS LOOKING INTO IT.
