**Air Cambodia has signed a landmark agreement to purchase 20 COMAC C909 aircraft**, marking the first time a foreign national airline has placed a series order for this Chinese-built regional jet. The contract was signed in Shanghai on July 17, 2026, in the presence of Cambodian Prime Minister Hun Manet, who was attending the World AI Conference. The C909, derived from the ARJ21 program, is a twin-engine regional jet configured for 78 to 97 passengers with a range of 2,225 to 3,700 km, making it ideal for Southeast Asian short- and medium-haul routes. **Beyond the aircraft sale, the deal includes a strategic memorandum of understanding between Cambodia's State Secretariat of Civil Aviation (SSCA) and COMAC.** This MoU covers technology transfer, human resources training, airport development and maintenance, and technical support for operations. Prime Minister Hun Manet praised the partnership, emphasizing that his government will support initiatives to modernize Cambodian aviation and enhance regional competitiveness. For ATPL and ATC students, this highlights the growing importance of understanding non-Western aircraft types and certification processes, as the C909 is certified by Chinese authorities but not yet by EASA or FAA. **Air Cambodia currently operates a mixed fleet of three Airbus A320s and three ATR 72-600s**, with orders for ten Boeing 737 MAX 8s. The airline is 30% state-owned, with Vietnam Airlines holding 14%, and the remainder controlled by Chinese and Hong Kong entities. China accounts for 32.1% of Air Cambodia's seat capacity, underscoring the strategic importance of the Chinese market. The choice of the C909 over Western alternatives can be seen as both a commercial decision and a political gesture, deepening ties between Phnom Penh and Beijing. **For aviation training professionals, this development underscores the need to stay abreast of emerging aircraft types and their operational characteristics.** The C909's entry into service with a national carrier outside China will require pilots and controllers to familiarize themselves with its systems, performance, and limitations. Additionally, the training and maintenance components of the MoU suggest that COMAC is investing in building local expertise, which could create opportunities for ATPL graduates and ATC trainees in the region. As the C909 expands its footprint, understanding its certification status and operational requirements will become increasingly relevant for those pursuing careers in international aviation.
