Civil Aviation Administration of China approve Ameco Beijing to act as a Designated Modification Design Organization Representative (DMDOR), which enabled Ameco Beijing to become the first enterprise to acquire such authorization in Chinese aviation industry.

Holding DMDOR, Ameco Beijing is entitled to perform some airworthiness approval under CAAC authorization, such as the design data approval for repair beyond specification and design approval for minor modification, etc. In the past within CAAC airworthiness maintenance/certificate system, only Aircraft Airworthiness Certification Department of CAAC or the regional airworthiness maintenance and certificate departments could perform all airworthiness approvals. At present, Ameco Beijing authorized by CAAC could perform modification design approval within the limited scope, greatly increasing the efficiency and attaining a more competitive edge in MRO services.

Ameco Beijing actively developed engineering services in recent years. It provided comprehensive technical services such as engineering support, MRO support, modification design and technical consultation for air carriers, engine condition monitoring, issuing engineering orders, engineering services for VIP aircraft modifications, developing non-routine repair schemes, troubleshooting solutions, and conducted Modification & Design Approval (MDA) for domestic customers.
