9Meridian – PA46-500TP Landing Gear The landing gear system is electrically activated, hydraulically actuated.Gear is held up by hydraulic pressure and down by spring loaded over-center locks within the actuators.Hydraulic actuators move the gear up and down.Once down and locked, hydraulic pressure is required to move the down-locks within the actuators, enabling the gear to be retracted.When retracted, hydraulic pressure keeps the gear in the retracted position. The absent hydraulic pressure, gear will extend through gravity.
