Comac C919 (C919)

The C919 is China's first mainline airliner of its own design and the centerpiece of a decades-long effort to build a domestic aviation industry. Comac, the Commercial Aircraft Corporation of China, was created in Shanghai in 2008 to build it, following the smaller ARJ21 regional jet, and the program was announced that year with the goal of competing with the Airbus A320 and Boeing 737 in the world's fastest-growing airline market.

The design is conventional: a single-aisle twinjet seating 158 to 192 with CFM International LEAP-1C engines, the Chinese variant of the engine that powers the A320neo and 737 MAX. Most major systems came from Western suppliers through joint ventures, including Honeywell avionics and flight controls, Liebherr landing gear and Collins cabin systems, with Chinese partners building the airframe. The first C919 rolled out in November 2015 and flew on May 5, 2017 from Shanghai Pudong; six prototypes then spent five years in flight testing, far longer than Comac had planned.

China's regulator, the CAAC, certified the C919 in September 2022, and China Eastern flew the first commercial service, Shanghai to Beijing, on May 28, 2023. Air China and China Southern followed in 2024, and by 2026 Comac had delivered several dozen aircraft, all to Chinese carriers, with orders claimed to exceed a thousand, nearly all from Chinese airlines and lessors. Comac has announced a shortened C919-600 and a stretched C919-800 and is developing a widebody, the C929.

Two things hold the C919 back. Production has been slower than Comac's targets, and the program depends on imported engines and systems; in 2025 Reuters reported that the US government had suspended some export licenses for the LEAP-1C, a reminder of how exposed the supply chain is. And the aircraft is certified only in China, so it cannot fly for airlines outside the country until the European or American regulators approve it, which as of late 2026 has not happened. The C919 is nonetheless a milestone, the first Chinese jet to carry fare-paying passengers in competition with Airbus and Boeing on China's busiest routes.

The C919 follows the A320 and 737 formula closely. Its fuselage is 3.96 meters wide, slightly wider than an A320's, allowing six-abreast economy at 18 inches per seat with a 19-inch middle, and it is 38.9 meters long, between an A320 and an A321. The wing spans 35.8 meters with large blended winglets, and it uses a supercritical airfoil developed in China with Russian wind-tunnel help; composites are used in the tail and control surfaces, with aluminum-lithium in parts of the fuselage.

The engines are two CFM International LEAP-1C turbofans of about 31,000 pounds of thrust, the same core as the A320neo's LEAP-1A with a Chinese-specific nacelle and thrust reverser built by Nexcelle. China's domestic alternative, the ACAE CJ-1000A, has been in testing for years and is intended to replace the LEAP eventually.

The flight deck has fly-by-wire controls with sidesticks and a Honeywell-supplied avionics suite with large displays, similar in concept to an A350's. Maximum takeoff weight is 75.1 tons for the standard version and 78.9 tons for the extended-range version, with ranges of about 2,200 and 3,000 nautical miles. Cruise speed is Mach 0.785. The numbers put the C919 close to the A320neo on paper, with a little less range and, Western analysts believe, somewhat higher weight.

The C919 flies only for Chinese airlines. China Eastern, the launch customer, operates the largest fleet on trunk routes from Shanghai Hongqiao and Pudong to Beijing, Chengdu, Guangzhou, Xi'an and other large cities, and in 2025 began using it on flights to Hong Kong. Air China and China Southern fly smaller fleets from Beijing and Guangzhou. Chinese lessors have placed further aircraft with other mainland carriers. No airline outside China has taken delivery because the type lacks certification from the FAA or EASA; Comac has signed memoranda with airlines in Southeast Asia and elsewhere that are contingent on that approval. On a tracker, every C919 is a Chinese domestic or regional flight, most of them to or from Shanghai.

From a seat the C919 feels like a new A320. China Eastern's standard layout has 164 seats: eight in business in 2-2 and 156 in economy at 3-3, with economy seats about 18 inches wide, the middle seat an inch wider, and pitch of 31 to 32 inches. The cabin has large overhead bins that take roll-aboards wheels-first, LED mood lighting and bigger windows than a 737's. The LEAP engines are quiet, and the quietest rows are forward of the wing. Lavatories are at the front and rear. Best seats are the window and aisle pairs in the first economy rows; the last rows are near the rear galley. Flights are domestic Chinese trunk routes of two to three hours, where the airplane has drawn curious passengers since 2023. The in-flight entertainment and Wi-Fi depend on the airline rather than the airframe.

The C919 looks like a slightly larger A320neo and is easy to misidentify at a glance. The clearest clues are the nose, which is longer and more pointed than an A320's with a cockpit windshield of six panes in a smooth, swept-back arrangement, and the tail, whose fin has a straight leading edge with a small, sharp dorsal fillet. The winglets are tall and blended, resembling an A320's sharklets. The engines are LEAP-1Cs, so the fan and nacelle look like a neo's. Liveries narrow it fast: a China Eastern, Air China or China Southern narrowbody with a Comac badge on the nose and the registration prefix B-919 or B-65 is a C919. Against the 737 MAX it has a taller stance and no chevrons on the engine nacelles.
