Should Easa & FAA Independently Test ARJ21

This Reuters article on China's first home-grown commercial passenger jet, the ARJ21, got me thinking about certification by the FAA & EASA.


Does China's opacity pose any unique problems for regulators when it comes to certifying the ARJ21? I mean, this is the same govt that covered up melamine in baby formula. What's a wing-crack or two??

I'd be interested in your thoughts.

(happy for people to draw parallels with Soviet aviation programs)

Quoting peh (Thread starter):

The article states:

During a stress test in mid-2010, the wings of the ARJ21 broke, or "cracked" in one executive's description, before the pressure applied reached regulatory norms.

So we can't speak about some simple cracks, the wing failed in the load test.

It looks like lot of further work to do.

Perhaps time for O'Leary to reconsider his plans with the C919, before the media gets wind of it.

I suspect his love of the C919 is overblown, just like the airplane itself:

Seems the ball is in MOL's court, but if he does nothing, he's going to be years behind his competitors in getting the benefit of the next generation of aircraft and engines.

Inspiration, move me brightly!
