China Aviation Supplies Co (CASC), established in 1980, is the first company founded within China’s civil aviation system. It is jointly owned by four shareholders: China Aviation Supplies Holding Company, China Southern Air Holding Company, China Aviation Capital Holding Co, and China Eastern Air Holding Company.
CASC specializes in civil aviation material support and is committed to providing customers with comprehensive aviation material support services.

CASC has built a mature aviation material support network, supported by extensive operational experience and a dedicated professional team. CASC provides efficient, high-quality and locally responsive services on a 24/7 basis. Major customers include leading domestic airlines and maintenance and repair organizations (MROs), and CASC maintains broad and close business relationships with key suppliers across the aviation industry.
CASC offers a wide range of integrated aviation material services, covering high-value component support (including engines, landing gears and thrust reversers for mainstream aircraft types), rotable pooling (repair and leasing), financial leasing, material sales and distribution, asset disposal, mutual material support, maintenance IT system development and application, bonded warehousing and logistics distribution.
These services are designed to deliver efficient, safe and timely solutions for various aviation material support demands.
1. Material Sales and Distribution: Material sales and distribution are based on consolidating customer needs and bulk purchase to effectively reduce costs. By leveraging a nationwide warehousing and logistics network, CASC enhances material availability and responsiveness through forward-positioned inventory to ensure proximity to end users. CASC has established long-term and stable consignment and distribution partnerships with major domestic airlines and MROs.
2. Rotable Pooling Services: By introducing international advanced support models, CASC offers shared material support services for various aircraft types – including repair and leasing options – that convert a one-time, large-scale inventory investment into a well-planned, manageable and stable operating expense. The service scope encompasses spare parts pool and one-for-one exchange services, as well as full project management covering the removal, repair, logistics and customs clearance of defective parts. CASC’s major clients are major domestic airlines and low-cost carriers, with support provided for aircraft types such as the B777, B787, B737NG, A350, A320 and C909 Aircraft.
3. Major Component Services: CASC delivers integrated solutions for key components such as landing gears, thrust reversers and APUs, covering leasing, exchange, repair and spares support. The company currently holds landing gear assets for B777, B787, B737NG, A350, A320 and C909 aircraft and has become a leading independent provider of major component pooling services in China.
4. Financial Leasing Services: CASC manages and leases a portfolio of high-value aviation assets, including aircraft, engines, landing gears and thrust reversers, as well as airport ground equipment and special-purpose vehicles. These services provide strong financial support for the development of new platforms for aviation material pooling and trading.
CASC obtained ISO 9001 and AS9120 quality management system certifications in 2007, becoming the first aviation material distributor in China’s civil aviation sector to meet international standards. In 2011, CASC became the first company in the industry certified as a Qualified Aviation Material Distributor by the China Civil Aviation Maintenance Association.
In 2018, CASC achieved China Customs AEO Advanced Certification. In 2019, it was listed in the FAA AC 0056B Conformity Directory as a recognized aviation material supplier.
CASC’s service and support network spans key cities across China – including Beijing, Shanghai, Chengdu, Xi’an, Guangzhou, Shenzhen, Shenyang, Qingdao, Chongqing, Changsha, Kunming, Zhengzhou, Harbin and Hong Kong – enabling the company to deliver efficient, high-quality and localized services on a 24/7 basis.

MTU Zhuhai is a globally leading aircraft engine MRO provider. In recent years, the two parties have established a deep strategic partnership in the field of engine maintenance, focusing on the core industry challenges and jointly developing targeted solutions. To enhance material planning and service responsiveness, CASC and MTU Zhuhai established a joint team dedicated to forecasting engine material demand and coordinating timely supply.
A specialized support team from CASC is also stationed to serve MTU Zuhai, providing high-quality service through localized and real-time responsiveness. All USD-based transactions are managed through APL (Hong Kong) Limited, CASC’s wholly owned subsidiary, which provides financial and operational support for bonded and overseas business activities.
The deep collaboration between CASC and MTU Zhuhai has delivered value on multiple levels:
1. Compared to direct procurement by the customer, CASC follows a centralized purchasing plan and delivers in batches, closely aligned with MTU Zhuhai’s production schedule. This approach effectively reduces inventory pressure on MTU Zhuhai.
2. By cooperating with upstream suppliers through centralized procurement, CASC secures inventory in advance despite ongoing supply chain constraints, significantly shortening lead time and improving overall supply chain efficiency.
CASC plans to expand this cooperation model to more engine maintenance and repair providers both in China and abroad, aiming to build a shared platform for engine maintenance and repair material support, and further enhance the overall stability of the supply chain.
