## Narrative

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

(23) SUBJECT AIRCRAFT LANDED WITHOUT MAIN LANDING GEAR IN THE DOWN POSITION. AIRCRAFT WAS PLACED ON JACKS AND A HYDRAULIC MULE WAS USED TO OPERATE THE LANDING GEAR SYSTEM.  POWERPACK WAS FOUND TO BE FULL OF HYDRAULIC OIL.  LANDING GEAR WAS OPERATED AND THERE WAS A VERY SLUGGISH OPERATION OF THE NOSE GEAR AND NO OPERATION OF BOTH MAIN LANDING GEARS.  LANDING GEAR ACTUATOR LEVER WAS PLACED IN THE DOWN POSITION AND THE NOSE GEAR CAME DOWN (BASICALLY A FREE FALL) THE MAIN LANDING GEAR DID NOT COME DOWN.  SEVERAL CYCLES WERE REQUIRED TO LOWER THE MAIN GEARS.  IT WAS DETERMINED THAT THE HYDRAULIC POWER PACK WAS DEFECTIVE.  HYDRAULIC POWER PACK WAS REMOVED AND SEND TO OVERHAUL SHOP BY THE OWNER.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
