On June 7, 2021, Liebherr LAMC Aviation Co., Ltd. (LLA), based in Changsha (China) celebrated a historic milestone: the delivery of the landing gear for the 100th serial Chinese regional jet ARJ21. The shipset includes the nose landing gear and the left and right hand main landing gear shock strut.
Of the cumulative 100 serial landing gear shipsets, Liebherr-Aerospace Lindenberg GmbH (Germany), the designer of the landing gear system, has delivered 19, and LLA 81 shipsets.
LLA, the joint venture between the Chinese company LAMC (AVIC Landing Gear Advanced Manufacturing Corp.) and Liebherr-Aerospace Lindenberg GmbH, had taken over the assembly of the ARJ21 landing gear from Liebherr-Aerospace and delivered the first ARJ21 landing gear assembled in Changsha in 2016.
During the last years, the joint venture has overcome many challenges and steadily improved its production and delivery capabilities, always ensuring that the company’s ARJ21 landing gear production capacity is greater than customer’s demand. LLA has thus won the recognition of COMAC with its outstanding delivery performance.
The three major capabilities of LLA include engineering research and development, supplier management as well as MRO that are steadily advancing as planned: The joint venture has dispatched an experienced engineering team to COMAC to provide on-site technical support. Furthermore, LLA procures autonomously standard parts and chemicals, and - with support of Liebherr-Aerospace Lindenberg GmbH - completed a quality system audit and approved several of its suppliers for standard parts and make-to-print parts. Finally yet importantly, an internal program to build-up MRO capabilities at LLA in Changsha has been launched.
