Right, MRJ like E2 was built on the hope that US scope clauses would change, which was a really stupid hope. And then they tried to downsize it to make it scope compliant, but that was a failure.MRJ was counting on US scope clauses changing, allowing the MRJ to be counted as a regional jet. Mitsubishi’s overconfidence in the program and their in-house designers meant the design was intrinsically incompatible with FAA standards.
ARJ-21 is first and foremost a project to gain experience in designing, building and maintaining a domestic jet airliner. With more than a hundred planes built, China’s aviation industry is now much more developed with it than without. If you look at it in this way, ARJ has been very successful in its role.
Not really. China is a large country. 50-70 seat turboprop doesn't work when competing against the world's great train system. turboprop doesn't even work in America and that's with scope clause and complete lack of high speed rail.I think it's not only the technical reasons that result in few operational hours. Chinese airlines are also wondering where to place ARJ21. It's too small, even in Xinjiang which we usually believe to be a big market for regional flights. Moreover, it's expensive to operate, especially the fuel efficiency. When they developed this aircraft, they were arguing to build a mainline or regional aircraft. The forecast demand for ARJ21 is 900 then. But when it was finally introduced, the actual demand is less than 100.
The regional aircraft that really hits the demand in China is a 50-70 seats turboprop aircraft. They are cheaper and easier for airlines to operate compared with jetliners. The required runway length is shorter, which will decrease the investment in regional airports. It is sad that MA700 is delayed because of the sanction of the engine.
ARJ21, despite being an lukewarm seller, served its role well as the key stepping stone for China's next generation passenger airliners, i.e. C919 and C929.ARJ-21 is a write-off. That's what it is.

well, generally the demand isn't there for turboprop. If the economy was there for Dash-8 and ER4s, it would still be operational. But having 2 pilots for 50 passengers is not economical. The passenger experience is also horrible on turboprops. I've done a few YYZ-LGA on ERJ-40 and they are not comfortable.The regional aviation market in the US is practically filled with Embraer and Bombardier regional jets. There isn't many turboprop airliners remaining.
Turboprop airliners fell out of favor in the US mainly due to:
1. Deregulation of the airline industry, causing many smaller regional airlines who operated those turboprop airliners to either collapse, or merge with others/larger airlines in order to survive.
2. The demand for hub-to-spoke passenger flight services in the US has been steadily increasing since the 1990s, rendering turboprop airliners with limited seats to lose out compared to larger regional jets.
@crash8pilot Since you are a pilot, feel free to chip in if our understandings are flawed and/or need rectification.
I wonder if the domestic engine can make MA700 meet its design target. I am sure the qualified AEP500 is sufficient, but it's under development, isn't it?
China's railway system is the best long-range train system in the world, far from the greatest train system in the world. China aims to provide all the residential areas with fast connections to regional big cities. No matter how they work, it is just not possible to link all the small cities in the less developed area with railways. The railway is not only expensive to build, but also expensive to maintain and operate. Besides, there are ambitious plans for general aviation. Most class A1 general airfield meets the requirement to operate turboprop aircraft like ATR and Dash8. They can easily upgrade it to a regional civil airport if necessary. I see it as a much cheaper solution than railways in these marginal regions.Not really.

If I just look at all the train stations that I pass by while going from Beijing to my hometown. There is no way each of those little village stops have their own airport. That's just nonsense.

My thoughts on the ARJ project:ARJ21, despite being an lukewarm seller, served its role well as the key stepping stone for China's next generation passenger airliners, i.e. C919 and C929.
Besides, China has built MD-80s and MD-90s for McDonnell Douglas in the past, so it is easier for COMAC to start from passenger aircrafts of similar size and category.

Let me make myself more clear (again): for less developed, marginal, less dense regions including Xinjiang, Tibetan plateau, Inner Mongolia, and Forest areas in Northeast China, regional aircraft is a more suitable way to provide fast connections to regional big cities than the railway. I was not talking about everywhere in China, especially I was not mentioning the East.If I just look at all the train stations that I pass by while going from Beijing to my hometown.

This is a serious question, how many long train trips have you taken in China? The last time I was in China, I took a 14 hour train ride from Yantai to Beijing which passed through like every small village imaginable rather than the flight, because I liked taking the overnight train.
Generally, I agree with you. The domestic market and economic scale are why ARJ and C919 could continue and finally accomplish.I want to point out one difference between MRJ and ARJ that nobody seems have mentioned.
Japan is a small country compared to China and US. For long distance travel there is the airplane, for shorter distance there is the HSR. MRJ has no market. That is reflected by Mitsubishi's hope on FAA clause, they rely on US market which is never going to happen.
China is large country with regions like Xinjiang, Tibet and Inner Mongolia, scarcely populated. These regions are similar to many areas in US. So there is a market for ARJ. And most importantly, ARJ does not need market outside of China to survive, although going abroad is a bonus. This means that no matter the economy performance, ARJ can go to its finishing line, MRJ is dead at birth. ARJ is a stepping stone for C-919 and CR-929, that is its key value, I regard it as success.
If we look over all the major players of aviation, we can see that the one who survives are the one with self-sustainable (home) market of population and landmass. Airbus has the whole Europe, US has the whole north America. Japan's failure is just like Brazil and Canada. Technology is the enabler, but home market is the decisive factor.
