LOCK STAYThe lock stay provides an over center stop and a geometric lock of the L/G.LOCK STAY ACTUATORDuring MLG extension the two lock stay actuator ports are open to return; a restrictor controls the rate of MLG extension. It is pressurized to extend during MLG door closure until hydraulic pressure on the door close line is released. During MLG retraction, the hydraulic fluid retracts the piston which opens the over centered lock, to fold the side stay and the lock stay against the lock springs.
