Chinese aircraft manufacturer COMAC (Commercial Aircraft Corporation of China) has officially approved Lufthansa Technik Shenzhen as their first MRO service provider in China for ARJ21 engine nacelles and components. Prior to the approval, the Lufthansa Technik subsidiary had successfully performed an on-site audit in December 2017.

Located in the Chinese province of Guangdong, Lufthansa Technik
Shenzhen, had added the COMAC ARJ21 regional jet to its service
portfolio in 2016. Since then, the company has carried out
modifications to several shipsets of the regional jet's engine fan
cowls and thrust reversers. Lufthansa Technik Shenzhen is authorized
by Middle River Aircraft Systems (MRAS), a subsidiary of General
Electric, to carry out maintenance, repair and overhaul for ARJ21
engine nacelles.
