Nice airplane. Who has ordered this airplane so far? Who is expected to order it? I would love to see one flying in Cubana colors in the future :)

Looks great. The cockpit windows remind me mostly of the Superjet, and the rest is like a larger CS300.

Re: Comac C919 initial engine run

It's been a while since I followed the C919. Originally there were plans to certify it via FAA and/or EU Authorities. Then, I heard that was pulled back for a possible future item as doing it in parallel was causing too many delays (to an already delayed project). At this point all customers listed in Wiki (admittedly not the best source) is in China, except for GECAS. My memory was the GECAS end clients are Chinese.

Does anyone know of the current plans for international certification; or is this just going to be a domestic Chinese aircraft (with perhaps Russian usage as well)?

Have a great day,

There's been a drawn out learning curve for Comac because they want the project taken seriously. This is actually sooner than I was guessing at the time of rollout (if you had asked me a year ago, I'd have probably have said 18 months).

Pictures of the joined fuselage and wings in September 2015 showed no signs that any systems installation had begun, nor was any wiring or plumbing visible. To get all of that stuff installed, tested, and ready to support full power-on for the first time with a workforce that has very limited experience with a new design in a year actually impresses me.

That is the question, have the lessons been learned? Or will this be another political project taking twice as long as planned and not so competitive at EIS?

The ARJ-21 didn't beat the MRJ and E2-175 to market by much.
There still are so few ARJ-21 delivered (Two last I saw). Despite being a low risk project with trailing technology.


Will the C919 fly? Yes. Will it enter service? Yes.

Will it be competitive? That is a question of maintenance, fuel burn, payload at range, turn times, dispatch reliability, and a big on purchase price.

In the C919? Nothing. Absolutely nothing.

Are you sure you're not thinking of the ARJ21 that was based on the DC-9? If so, the fuselage is definitely inspired by the DC-9 although has significant structural changes. The flight control system is mostly carried over - it is a hybrid of manual trim tabs and hydraulics.

Regarding the C919 itself: I'm actually rather surprised that it has gone /this quickly/, given the debacle that was ARJ21 - including the fact that they /still/ haven't managed to commence deliveries to clients (2 delivered? That's just so they can say it was delivered)... the ARJ21 still isn't in any scheduled revenue service, and it reeks of the Shanghai Y-10 debacle. Naturally, the ARJ21 was designed and led by the same engineer who gave us the Y-10, so little surprise there that it has panned out as it did...

So, they have a plane built, powered on, with engines running? That's better than their previous track record. Congratulations to them.

There are no plans to obtain FAA certification, for now the C919 will just be a domestic aircraft.

Meh, define "quickly". First flight has slipped from 2015 to early 2017 (if no longer) and EIS has slipped from 2018 to 2020.

sounds par for course for any new-from-the-ground-up programme these days Karel. (A380? 787? CS100?)

Which implies "quickly" for an organisation that is doing it for the first time .. :)

We're talking about most of the same companies involved in the ARJ-21. 2 years delay (so far) is a huge improvement for them.

Keep in mind also, they're leaning heavily on the expertise of their western suppliers for a lot of the aircraft systems. There are some things (engineering experience) money can't buy. For everything else, there's the international currency market.

My bet is that the MC-21 will beat the C919 into first flight, even though the Russian bird is delayed it is only a few weeks behind the Chinese bird. Will be interesting to see which one will take off first.

When in China and out drinking beer, a friend of my friend i met there told me he was working on designing airplanes in China. But his project was not for a big plane, it was a small single engine plane that was only allowed to use China made parts (he said i sucked because of that.. :) ).
Anyway, he told me the biggest problems was with the certifications. Because the persons who wrote the Chinese certification rules did not understand what they where doing. They probably just translated another countrys rules to Chinese. And fulfilling certification requirements that you or the organization that handles the certifications do not understand is kind of hard. But they are fixing the rules as they move along.
This has resulted in lots of redesign. But when making the next plane, they will know from the beginning what requirements they need to pass.

These engineer I met seemed to be a really smart guy and he had studied at a respected university in Europe. I think the skills for making good planes are available in China. The organizations still has some catch up to do.

Would guess this was a problem also for the ARJ-21. And the C919 i not that delayed right? Still almost on time if you compare to western programs? :)

IIRC they're not going for any western (EASA or FAA) certification so they have probably reduced the paperwork and hopefully not cut too many corners.

First flight is scheduled for July.

China's long-awaited C919 airliner will finally take to the skies in July this year, state media report. The state-owned Commercial Aircraft Corp of China (COMAC) first unveiled the single-aisled, twin-engined jet in November 2015, leaving analysts wondering whether it can compete with major manufacturers such as Airbus and Boeing. The single-aisle aircraft, which can seat 168 passengers, has installed its on-board system and undertaken a series of load tests.

We're getting really close now:

Aircraft 101 has conducted three high-speed taxi tests, where no major issues surfaced. A fourth test, involving a high-speed ground run to the point of a nose-gear lift-off, is scheduled for 23 April, they add.

"Once the nose wheel can be lifted with no issues, then the aircraft will proceed to first flight. The jet is basically ready for a first flight. There are no major issues," says the source. Another source adds that Comac will do at least two nose-gear lift-offs before first flight.

Nose gear looks kind of 757-ish aft to me as well. Cockpit looks stunning.. reminds me of the 787 cockpit mixed with Airbus side sticks and center pedestal. Looks like they have pull-out tray tables as well, maybe with a keyboard? Don't know if it's a good idea with all the black colored areas when dust, dirt and scratch marks start appearing.

I love that huge winglet with ANA written on it! :bigthumbsup:

I look forward to seeing the thing fly for the first time, presumably later this month

The C919 received its flight permit!

The airframer also received a special flight permit from the Civil Aviation Administration of China on 22 April, as well as a temporary civil aircraft registration and an aircraft station licence. The flight permit and the station licence both expire on 31 May, a clear sign that Comac is confident of a C919 maiden sortie next month.

A350 and 787 did a nose up test as well, flight test crews can validate the rotation speed before taking the aircraft to the skies.


Rotation speed is the speed at which it should fly. You can rotate it before that though, so lifting the nose in itself doesn't prove anything.

This is demonstrated with the tests where they drag the tail.

Logically for first flight you simply apply a big margin of safety on calculated speeds.

For the gear: did airbus themselves design it or was it a supplier? If som could a supplyer sell the same gear to two different manufacturers?
