Probable cause
The inadequate servicing of the hydraulic fluid by maintenance personnel and the pilot's failure to extend the landing gear manually.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The main landing gear collapsed during the rollout of a full stop landing. The hydraulic power pack unit had been replaced recently. This was only the second flight and second landing since the replacement of the unit. The hydraulic reservoir was slightly less than half full. Gear operation could not be obtained in a functional test with the hydraulicfluid level existent in reservoir. Normal gear function was obtained after reservoir was serviced to operating capacity.
