Liebherr-Aerospace Lindenberg GmbH (Germany), center of excellence for flight controls, actuation, landing gear systems, gears, gearboxes as well as electronics, was selected by Spirit AeroSystems to supply the thrust reverser actuation system. A first in the history of the German aircraft OEM.

Leveraging on its expertise, Liebherr developed the new system in a short time with low development risk. It is fully compliant to the latest REACH (Registration, Evaluation and Authorization of Chemicals) requirements, which is an important step on the path towards more environmental friendly aircraft.

Liebherr profits from its knowledge of hydraulic and mechanical actuation that is proven by uncountable flight hours in commercial and business aviation. The thrust reverser actuation is being developed based on technologies that are available and mature at Liebherr.

Despite the very demanding situation during the Covid-pandemic, which allows only virtual meetings, the high quality of the cooperation between Spirit AeroSystems and Liebherr enabled the development team to achieve the first significant development milestone in time. The successful Preliminary Design Review was as well a demonstration of the seamless collaboration within the worldwide Liebherr liaison network, in this case with the Liebherr office in Seattle, WA (USA), which assures always the proximity to the Customer.

Liebherr is very pleased to be able to count Spirit AeroSystems among its customers and is looking forward to continue the successful collaboration.
