MANUAL LANDING GEAR EXTENSION
Should a failure occur in the normal actuation system, landing gear extension is possible by pulling the landing gear manual release handle located in the centre pedestal of the flight compartment. The design configuration allows the system to be restowed to its initial position under any conditions by simply reversing the manual release handle movement.
NOTE
Manual landing gear extension is carried out with the landing gear control lever in the down position.
For operation of the manual landing gear extension procedures, refer to the non-normal procedures, MANUAL LANDING GEAR EXTENSION in the Airplane Flight Manual.
NOTE
The landing gear manual release handle will ratchet from the stow to the extend position upon selection. The handle will lock in a given detent position if released during extension only.
When the handle is selected to stow following a full extension, the handle will not ratchet (lock) if released. When the “PUSH FULLY TO STOW”button is pushed, care should be taken to guide the handle (under spring tension) to its full stowed position.
