Narrative

OUT OF ZZZ; A MASTER WARNING WAS OBSERVED; INDICATING HYD QUANTITY LOW WITH ASSOCIATED DROP IN PRESSURE. THE SYS WAS ISOLATED BY SWITCHING SYS TO INERTIAL DOORS. NORMAL FLT CONDITIONS WERE ENCOUNTERED. UPON DSCNT; THE DSCNT BEFORE LNDG CHKLIST WAS EXECUTED WITH NO GEAR ACTION. THE EMER GEAR EXTENSION CHKLIST WAS PERFORMED; WITH NO RESULT. IMMEDIATELY EXECUTED THE EMER GEAR 'EXTENSION ONLY' CHKLIST. AS A RESULT; THE GEAR EXTENDED AND WAS INDICATING DOWN. PLTS THEN REQUESTED AND PERFORMED A 'FLY-BY' OF THE CTL TWR IN ORDER TO VISUALLY CONFIRM NOSE GEAR DOWN; WHICH WAS VERIFIED BY ATC. MAIN GEAR WAS CONFIRMED DOWN VISUALLY BY BOTH PLTS. NOSE GEAR WAS CONFIRMED DOWN VISUALLY BY BAGGAGE COMPARTMENT MECHANICAL INDICATOR. PAX WERE THEN BRIEFED OF A POSSIBLE ROUGH LNDG AND ADVISED TO TIGHTLY FASTEN SEATBELTS. NOTE: HYD HAND PUMP WAS CONSTANTLY PUMPED BY COPLT IN ORDER TO RETAIN POSITIVE PRESSURE. A NO-FLAP SMOOTH LNDG WAS MADE ALONG RWY CTRLINE; WITH BOTH MAIN GEAR CONTACTING FIRST. NOTE: MAIN GEAR HELD; READ 'NO COLLAPSE.' WHEN NOSE GEAR CONTACTED GND; IT COLLAPSED. THE NOSE OF AIRPLANE WAS IMMEDIATELY RAISED AERODYNAMICALLY WITH THE ELEVATOR. IMMEDIATELY; ACFT STARTED AND LISTING TO THE L UNTIL CONTACT WAS MADE WITH THE GND BY THE FUSELAGE. ACFT THEN PROCEEDED TO LIFT OFF OF RWY AND SKIDDED TO A HALT. ENG AND ALL SYS WERE THEN SHUT DOWN. PAX WERE IMMEDIATELY ASKED OF THEIR CONDITIONS; TO WHICH 'ALL OK' AND 'THUMBS UP' WERE GIVEN. AN ORDERLY EVAC WAS INITIATED BY COPLT; WITH ARPT CFR ASSISTING ALMOST IMMEDIATELY. ALL PERSONS EVACED SAFELY WITHOUT INCIDENT; WITH EACH PAX BRIEFLY INTERVIEWED AND RESPONDING TO BE IN GOOD CONDITION. ACFT WAS THEN SECURED BY FAA AND ALL OTHER AGENCIES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT AFTER ISOLATING THE HYD SYS HE ELECTED TO CONTINUE TO DEST; AS HE FELT THAT IT WAS SAFER TO LAND WHERE THERE WAS EMER EQUIP TO ASSIST IN THE EVENT OF A FIRE/EVAC. ADDITIONALLY; HE WAS NOT SURE OF THE POS OF HIS LNDG GEAR AND A WATER LNDG WITH THE GEAR EXTENDED IS VERY DANGEROUS. THE ACFT SUSTAINED MINOR DAMAGE AND NO INJURIES WERE SUSTAINED DURING THE INCIDENT.
