With a trio of aircraft at various stages of development and


production, China’s national airframer faces a gauntlet of


engineering, logistical, political and commercial trials

omac appears to be hitting its air-
craft development stride, with the
ARJ21, C919 and CR929 all making
progress. But there are strong
doubts about how well China’s national air-
framer can implement all three programmes.
It has been a busy 11 years for the compa-
ny, which was originally launched to build
the C919, but soon inherited the ARJ21 re-
gional jet programme from AVIC. The logic
was, and still appears to be, that the regional
jet would be a bridge to the bigger prize of the
C919, which would compete with the Airbus
A320 family and Boeing 737 series.
But the manufacturer’s scope increased
again in June 2016 when it signed an agree-
ment with Russia’s United Aircraft (UAC) to
jointly develop the widebody CR929 under
the China-Russia Aircraft Company (CRAIC)
joint venture. “The ARJ21 is an explorer,

opening the path for China’s civil aviation de-
velopment,” says CR929 programme director
Xie Canjun. “We hope the C919 will be a suc-
cessful aircraft type. We want the CR929 to be
a commercially competitive aircraft of inter-
national standard.”
Comac now has three programmes in dif-
ferent stages of development and production


  • a challenge that has historically taken West-
    ern OEMs decades to successfully manage.
    Rob Morris, global head of consultancy at As-
    cend by Cirium, notes that “the track record of
    Comac and other emerging OEMs suggests
    that the certification and entry into service
    could be challenged”.


FINISHING ARJ21
The ARJ21, which has been in service for
nearly four years while still having aspects of
its design refined, is the main reason why
those doubts exist. When it was launched in
2002, the GE Aviation CF34-10A-powered re-

gional jet was scheduled to enter service in


  1. However, its first flight only occurred in
    2008, and it would take six more years to ob-
    tain type certification. It was then a further
    three years, in 2017, before a production cer-
    tificate from the Civil Aviation Administra-
    tion of China (CAAC) was secured, allowing
    batch production to move forward.
    That did not stop the jet from entering ser-
    vice in November 2015 with launch customer
    Chengdu Airlines – a carrier partially owned
    by Comac.
    Since then, however, a series of problems
    have emerged and further development work
    has been undertaken. Wang Xingwei, ARJ21
    programme office director, told FlightGlobal
    in February that efforts were being made to
    reduce the aircraft’s weight by using lighter
    materials, optimising systems, installing light-
    er seats and making some wiring changes. Im-
    provements are also being made to the flight
    control layout and to the cockpit, with the
    adoption of a “dark cockpit concept” which
    makes alerts more pronounced to the crew.
    Comac is also looking to raise the ARJ21’s
    seat count by adding up to seven seats, taking
    its capacity up to 89 in a dual-class layout, or
    97 in a single-class configuration.
    As of mid-May, Chengdu Airlines had six
    ARJ21s in service, while start-up carrier
    CR929 widebody has 18-24 months earmarked for flight tests and 2027 certification goal Genghis Khan Airlines had taken delivery of
