What China Aircraft Services does

China Aircraft Services Limited (CASL / 中飛公司) is a Hong Kong-based private joint venture founded in 1995 that provides integrated aircraft maintenance, repair and overhaul (MRO) plus ground support services to commercial airlines and business jet operators at Hong Kong International Airport (HKIA). Its service portfolio spans seven lines: line maintenance (pre-flight, transit, overnight checks with 24/7 AOG support), base maintenance (C-checks for A320 and B737NG, structural inspections, cabin modifications, engine and landing gear replacement, full aircraft painting), cabin services (cleaning, provisioning, exterior washing), ramp services (ground support equipment), supply chain management (3,500 sqm of warehouse facilities plus customs and dangerous goods handling), and business aircraft maintenance (Gulfstream and Bombardier platforms). The company operates a base maintenance hangar opened in 2009 that can simultaneously accommodate one wide-body and one narrow-body aircraft.

CASL makes money through B2B professional services contracts — scope-based quotations rather than publicly disclosed pricing — with airlines operating at HKIA and, via multi-jurisdiction regulatory approvals, global carriers requiring technical handling. Its regulatory footprint spans HKAR-145, EASA.145, FAA, China CAAC, and 15+ other aviation authorities. The company is jointly owned by China National Aviation Corporation (Group) Limited (CNAC Group, 47.97%), Hutchison CCF Investments Limited (47.97%), and China Airlines Limited (4.06%) — a state-linked, diversified shareholder base that has evolved since founding from an original CNAC/British Airways/Hutchison Whampoa structure. CASL holds an HKIA franchise license (originally 1996, renewed 2006) and runs an HKAR-147-approved maintenance training organization. It employs 800+ staff and serves an enterprise customer base that includes Delta, JAL, Cathay Pacific, United Airlines, British Airways, Air Macau, Virgin Atlantic, Jeju Air, and Suparna Airlines, among others.

• AAR Corp: AAR is a US-headquartered independent MRO providing airframe maintenance, component repair, and integrated supply chain services to commercial and government aviation customers. Its aviation supply chain and component MRO capabilities parallel CASL's supply chain management and component-adjacent services.
• ST Engineering (Aerospace): ST Engineering's aerospace arm operates one of the world's largest airframe MRO networks with base maintenance for A380, A350, B777 and B787, plus engine and component MRO.

• SIA Engineering Company: SIA Engineering is a Singapore-based, broad-portfolio MRO serving 80+ airlines globally with line maintenance at 30+ airports and major base maintenance in Singapore. It is comparable as a regional incumbent offering a similar one-stop MRO product to airlines that overlap with CASL's customer base (Cathay, JAL, BA).
• Lufthansa Technik: Lufthansa Technik is a global MRO leader providing base maintenance, line maintenance, engine services and VIP/business jet completion. Its global line maintenance network and partnerships (including with Ameco) overlap with CASL's commercial and business aviation MRO offering.

Direct peers

• HAECO (Hong Kong Aircraft Engineering Company): HAECO is the other major Hong Kong-based aircraft MRO, operating base maintenance, line maintenance, cabin services and component overhaul at Hong Kong International Airport. It is the closest direct competitor to CASL on its home turf, competing for the same HKIA franchise work and overlapping on A320/B737NG and wide-body capabilities.
• Ameco Beijing: Ameco is a Beijing-based Air China/Lufthansa Technik joint venture providing line maintenance, base maintenance (C-check, D-check), engine MRO and component services. It is one of China's largest MROs and directly comparable to CASL in service mix, with broader mainland footprint and similar flag-carrier alignment.
• GAMECO (Guangzhou Aircraft Maintenance & Engineering Company): GAMECO is a major joint-venture MRO at Guangzhou Baiyun Airport (Hutchison Whampoa is a shareholder alongside CASL's), providing line and base maintenance for A320, B737NG/MAX and B777/A330 aircraft. It competes directly with CASL for Greater Bay Area MRO contracts and is structurally linked through Hutchison ownership.
• TAECO (Taikoo Aircraft Engineering Company): TAECO is the HAECO Group's Xiamen-based MRO providing line maintenance, base maintenance, cabin services and component overhaul. It is a like-for-like competitor in scope of services and Asian flag-carrier customer mix, and competes with CASL for China-region base maintenance contracts.
