## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) WHILE IN CRUISE FLIGHT, PILOT HEARD A BANG AND THEN SAW THE GEAR UNSAFE LIGHT ILLUMINATE. PILOT ALSO NOTICED AN INCREASE IN DRAG AND THE AIRCRAFT SLOWED. PILOT PLACED THE GEAR HANDLE IN THE DOWN POSITION, BUT NOTHING HAPPENED. HE TURNED BACK TOWARD KPWA AND TRIED TO MANUALLY EXTEND THE LANDING GEAR USING THE HAND-PUMP. HE PUMPED THE HANDLE SEVERAL TIMES BUT THERE WAS NO RESISTANCE AND THE GEAR UNSAFE LIGHT WAS STILL ON. HE DECLARED AN EMERGENCY AND RETURNED TO KPWA. TOWER ADVISED HIM TAHT THE NOSE GEAR APPEARED TO BE DOWN, BUT THAT THE MAIN GEAR WERE IN A PARTIALLY RETRACTED POSITION. THE PILOT THEN LANDED THE AIRCRAFT. ON TOUCHDOWN, THE NOSE GEAR REMAINED LOCKED, BUT THE AIRCRAFT SETTLED ON THE PARTIALLY EXTENDED MAIN GEAR AND THE HORIZONTAL STABILIZER. THE AIRCRAFT SLID TO A STOP ON THE RUNWAY AND THE PILOT/PASSENGER EVACUATED WITH NO INJURIES. FOLLOW-UP INVESTIGATION REVEALED THAT THE NOSE GEAR ACTUATOR 'UP' HYDRAULIC FLEX LINE HAD FAILED AT THE FITTING AND ALL OF THE SYSTEM HYDRAULIC FLUID ESCAPED.
