Global Market Opens For C919 As EASA Works On Certification
As Comac readies the C919 for flight, sales opportunities widen

The
finally has a path to widespread acceptance of its airworthiness, with the
(EASA) beginning work on validating the narrowbody airliner’s prospective Chinese type certificate.
Announcement of the work at a meeting in Shanghai between Chinese and EASA aviation officials comes within days of the planned first flight of the C919, which until now has faced automatic rejection by airlines in countries that demand EASA or
certification or validation. For most of the world’s commercial aircraft market, a type certificate from the Civil Aviation Administration of China (
) is not enough.
The state manufacturer still will face great challenges in selling the C919 internationally, even with EASA endorsement. And there is no sign that the FAA will validate the type certificate. Thus, the U.S. market will remain closed to Comac, though sales prospects there are likely weak.
C919 Program
Launched in 2008 with first delivery targeted for 2016.
First flight is likely on May 3-7, delivery not before 2020.
CFM supplies the Leap 1C engine, Avic the airframe structure.
The C919, powered by the
1C engine, is designed for standard seating for 158 passengers in a two-class configuration.
The first flight will be about three years later than the planned June 2014 date. The CAAC says in a leaked internal report that the C919 will fly in May. The likely time is May 3-7, says an industry source. A year ago, the target was the end of 2016.
Comac has stopped publicly updating its repeatedly delayed targets for first delivery, but launch operator
is unlikely to receive a C919 before 2020.
In relation to CAAC-EASA cooperation on airworthiness regulation, the C919 will be a “technical assessment project,” say CAAC-sanctioned official media, reporting on the April 26 meeting. That must mean C919 development will be the basis of the shadow certification project for a bilateral aviation safety agreement (BASA) that the CAAC and EASA say they are drafting.
Under a BASA, civil aviation authorities validate each other’s type certificates, recognizing each other’s competence in airworthiness assessment. To achieve that agreement with the CAAC, EASA will observe its Chinese counterpart’s certification work. If satisfied, the European agency will not only validate the type certificate for the C919 but routinely recognize subsequent CAAC certifications.
When China launched C919 development in 2008, it expected the CAAC and FAA to shortly conclude a BASA based on shadow certification of the
regional jet, so the C919 would receive FAA validation. But ARJ21 development ran so late that the FAA required design changes for compliance with new safety rules, Comac officials have said. As a result, the U.S. agency has still not validated the ARJ21’s CAAC type certificate, and no U.S.-Chinese BASA has been concluded. That left the C919 in the lurch from which EASA is expected to rescue it.

The C919’s EASA shadow certification effort will not be straightforward, because the CAAC has been closely involved in the project since about the time detail design began in 2011. EASA will need to know what exactly the CAAC has done in that time, so six years of records and engineering data will need to be reviewed. Five years ago the FAA, standing on the sidelines, assumed the CAAC’s C919 work, if eventually reviewed, could turn out to be acceptable thanks to what the Chinese agency had learned from the ARJ21 program.
Comac has completed taxi-testing of the first C919 prototype and received CAAC authorization to fly it. In the final taxi tests, the aircraft lifted its nose gear in fast runs at Shanghai Pudong International Airport, adjacent to Comac’s main plant.
Taxi tests began in December 2016. The prototype was used for 14 sessions totaling 35 hr. at low to medium speeds, up to 150 kph (93 mph), says the Ministry of Industry and Information Technology. The first high-speed test, on April 16, reached 170 kph and was aimed mainly at verifying the function of the spoilers.
“As of today, all of the taxi tests needed before the first flight have been completed,” says C919 chief designer Wu Guanghui. “All of the test data is reliable and effective.”
The program will use six flight-test aircraft. The first bears the manufacturer’s serial No. 10101 and is known as Unit 101. It was rolled out in November 2015.
