Door Actuation

The landing gear door actuation subsystem allows to close the landing gear bay doors once the aircraft is in the air and to open them when the aircraft is about to land.

Liebherr designs and manufactures in-house the hydraulic and mechanical parts of the extension and retraction subsystem (actuators, valves and up-lock boxes) and integrates them together with the electronic hardware and software controls made in-house.

Liebherr supplies door actuation subsystems to commercial aircraft.
