Emergency Flaps
Procedure
|
In case of failure of the engine-driven hydraulic pump, flaps may be manually lowered by use of the emergency hand pump located on the left of the pilot's seat.
|
Emergency Gear
Procedure
|
In case of failure of engine-driven hydraulic pump, to retract landing gear, move control handle to UP position as usual, then operate the hand pump until the panel warning light indicates the gear is up and locked.
To extend landing gear, move control lever to the DOWN position as usual to releases the gear, which should drop into position and lock due to its own weight. If gear is still not locked down, yaw the plane from side-to-side.
WARNING -- Always complete the landing-gear cycle, if possible. If handle is moved to UP, allow gear to go completely up before moving handle again. If handle is moved to DOWN, allow gear to go completely down before moving handle again.
