CORP LTT HAS GEAR EXTENSION PROB.

Narrative

DURING THE CHKLIST; WHEN THE CAPT CALLED FOR THE GEAR; THE GEAR CTL LEVER WOULD NOT MOVE TO THE DOWN POS. WE CLBED IN VFR CONDITIONS TO 17500 FT AND REQUESTED WITH ZDV FOR AN IFR CLRNC TO DEN ARPT. WE KNEW THIS WAS THE BEST FACILITY TO HANDLE OUR PROB IF WE COULD NOT GET THE GEAR DOWN. DEN ARPT HAS CRASH/FIRE/RESCUE EQUIP AND SAFETY WAS OUR FIRST CONSIDERATION. ON OUR INITIAL CONTACT WITH ZDV; WE ADVISED THEM OF ACFT GEAR PROB. THEY ASKED IF WE WANTED TO DECLARE AN EMER. WE STATED 'NOT AT THIS TIME.' OUT INTENTION WAS TO ENTER A HOLDING PATTERN AND THEN GO THROUGH THE EMER CHKLIST AND TRY TO BLOW THE GEAR DOWN. ZDV CLRED US DIRECT DRAKO; DIRECT DEN. ENRTE TO DRAKO AT 17000 FT THE CAPT REQUESTED I CALL MAINT TO EXPLAIN OUR PROB AND TO SEE IF THEY KNEW OF ANYTHING WE COULD DO TO GET THE GEAR LEVER DOWN. THEY SAID IT WAS PROBABLY A SOLENOID PIN AND THAT IT WAS MOST LIKELY STUCK AND THAT THE GEAR LEVER WOULD NOT GO DOWN. THEY ALSO SAID THE EMER SYS IS DESIGNED TO WORK WITH THE GEAR LEVER IN THE UP OR DOWN POS. ZDV ASKED IF WE WERE READY TO COPY A HOLDING CLRNC AND WE ASKED FOR VECTORS WHICH THEY GAVE US. WE WENT THROUGH THE EMER GEAR EXTENSION CHKLIST; STEP BY STEP; AND WERE SUCCESSFUL IN GETTING THE GEAR TO EXTEND. WE THEN ADVISED DEN WE WERE READY TO RETURN TO DEN ARPT TO LAND. AT THAT TIME WE ADVISED DEN APCH THAT CRASH/FIRE/RESCUE EQUIP WAS NOT NEEDED. WE COMPLETED THE LNDG WITH NO PROB OR INCIDENT. MAINT AT DEN FOUND THAT IT WAS A PIN IN THE GEAR CTL BOX BEHIND THE INST PANEL.
