SA2326-A; UNABLE TO EXTEND NOSE GEAR; RETURNS FOR LNDG AT FLL.

Narrative

MY CAPT AND I WERE PLANNING TO FLY TO MARSH HARBOUR. WHILE FLYING; THE ATC CTLR NOTICED THAT OUR XPONDER WAS SHOWING THAT WE WERE 10000 FT HIGH; SO THEN WE RECYCLED THE XPONDER TO #2. ONCE WE DID; IT SHOWED 12000 FT HIGH. THEN WE NOTICED THAT MY HSI BECAME INOP AND WE DECIDED TO RETURN TO THE ARPT. WE DID THE APCH AND NOTICED THAT WHEN WE REACHED THE OM TO PUT THE LNDG GEAR DOWN; THERE WERE ONLY 2 GREEN LIGHTS SHOWING; WHICH WERE ON THE MAINS. THE NOSEWHEEL WAS STUCK. WE FLEW PAST THE TWR TO CONFIRM THE NOSEWHEEL WAS ACTUALLY UP. WE DECLARED AN EMER. WE BEGAN THE EMER EXTENSION PROC. THE NOSEWHEEL WOULD NOT COME DOWN. THE LEVER WAS HARD TO PUMP. I KEPT PUMPING AND STILL THE NOSE GEAR WOULDN'T COME DOWN. THE EMER EXTENSION LEVER WAS SO HARD THAT THE LEVER WAS STUCK STRAIGHT UP. I LITERALLY HAD TO GET OUT OF MY SEAT TO KICK IT DOWN. THEN WE TRIED OTHER OPTIONS. WE TRIED CHKING THE CIRCUIT BREAKERS. WE XFERRED THE ELECTRICAL SYS. WE TRIED EVERYTHING. WE KEPT RECYCLING THE GEAR. MEANWHILE; WE DID THE APCH 4 TIMES AND KEPT TRYING TO BRING THAT GEAR DOWN. WE HAD HYD PRESSURE. NOTHING COULD BRING THE NOSE GEAR DOWN. ON THE LAST APCH; WE DECIDED TO LAND THE ACFT. WE LANDED AND THE EMER VEHICLES CAME OVER. ONCE WE LANDED; THE ACFT MAIN HIT THE GND AND WE WENT TO THE SIDE. THE NOSE GEAR WAS STILL UP. THE PROP WAS SLIGHTLY BENT. ONCE THE ACFT LANDED; THE IMPACT CAUSED FUEL LEAKS EVERYWHERE.
