How long shall type inspection authorization take?

look like the guy smell some thing beforehand.

COMAC chairman resigns to take Hebei governorship

Delayed again!

Test flights bring about another delay, at least out of 2011:

Got the engines in October – but EIS is delayed to 2011 3rd quarter or later:

Further delayed to 4th quarter or later, for Chinese certification shall come in September 2011:

The reason for the delay turns out to have been breaking the (Antonov) wing:

Comac hopes to get production GE engines in fourth quarter and enter into service early in 2011:

its a strange world we live in
DC9s first flew carrying about 90 passengers, and were eventually stretched to carry double that
the regional jets began from executive jet size until the carry 60 people
this new chinese plane looks like its filling the gap left by the now retired DC9/737 early series planes

Which is nicely filled with E195 and CRJ1000. No-one needs the ARJ21.

Yeah, but its not like theres been a huge gap where jets of that size didnt exist. :confused:

First export customer!

Comac got first export customer for ARJ-21. Lao Airlines:

looks like a dc9 and a CRJ crossed

That sounds like management “speak” there, Schorsch! :p

I’m climbing up the corporate ladder … 😀

The cross-section of the fuselage is identical (the length of ARJ21-700 does not match the length of any DC-9 model).

Taking out some frames from the constant section is a no-brainer.

So that it would not grow past ARJ21-900… and would not compete against CS100. Whose fuselage and wingbox are also made by AVIC. And Cseries does have a new cross-section and new tooling.

The Chinese are not stupid. They know that fighting an A319/A320 is not working. They are taking existing stuff off the shelf and try to do it themselves, basically a use-case for their industry. the results don’t impress, but it is a big learning program for their industry.

The CF-34 is a safe choice, not truly inventive, but taking General Electric into the boat helps the business case (which isn’t meant to produce any cash anyways).

It wasn’t reverse engineered, it basically IS a DC-9. The fuselage is identical and was meant to be so as AVIC had tooling and experience in manufacturing the DC-9 (or MD-90).

The cross-section of the fuselage is identical (the length of ARJ21-700 does not match the length of any DC-9 model).

The engine is CF-34 (same as A-10!), which limits it in growth potential.

The wing is modified with supercritical profile.
Nobody should expect too much from that aerodynamic-wise, but it allows a thicker and lighter wing with more volume.

In the end: it is not innovative, but it still is a useful aircraft. The last part is hard to say for me as I prefer the over-engineered Euro-tech solutions. However, the ARJ-21 – despite being yesterdays’ design – still is in one league with the E-Jets.

I wouldn’t be surprised if this was actualy reverse engineered from a DC-9 lol

It still looks like a DC-9 21 with winglets.

Had to giggle! 😀

ARJ21-700 is longer than DC-9-10, but shorter than DC-9-30.
