Liebherr supplies landing gear actuators for Boeing’s 777 and 777X aircraft

Since the contract for the power control actuator of the 777 and 777X’s main gear steering components was signed in 2018, Liebherr and Boeing have been working diligently to design, manufacture and test the new actuator.

The first delivery of two units to Boeing’s lab marks a major milestone for this built-to-print project.

A dedicated team of manufacturing and qualification engineers has been working meticulously to ensure that this new actuator exceeds all requirements.

Liebherr-Aerospace will manufacture (or build) these parts specifically for Boeing’s 777 and 777X programs.

Liebherr’s competence center for flight controls, gears, gearboxes and landing gears, Liebherr-Aerospace Lindenberg GmbH, Lindenberg (Germany) was selected to manufacture and test the actuator because the company understands that cost-effectiveness, quality and efficiency are the linchpin of successful long-term partnerships.

Boeing and Liebherr are looking forward to the full-scale production of the units in 2021.

The power control actuators are part of the main gear steering system. They support taxi maneuvers of the aircraft and reduce tire wear. Together with the main gear steering control unit and the nose gear steering position transducer, Liebherr supplies the complete main gear steering system.
