A-checks are at 850 hours and C-checks at 8,500 hours, with heavy structural checks at 12 years compared to the usual eight years for most other types. There are no daily/weekly checks,. The first check is at 100 hours and everything before that is on demand. In practice, an operator can fly the aircraft for over a week before needing to do the first check.
Both will do very well on maintenance. Embraer is promising 15% to 25% lower maintenance costs than the original E-jets. Now some of that is the CF-34 vs. GTF
. Much is the subsystems.
Bombardier has worked hard to reduce maintenance costs by extending intervals.
Embraer has worked hard to reduce maintenance by re-designing sub-systems to be far more reliable (lessons learned from improving an existing type with FBW technology).
Both have extended intervals, for the E2-jets:
On the maintenance side, intervals are being extended to 7,500 flight hours compared to 6,000 flight hours of the competition.
So we'll see which is cheaper to maintain.
I'm very curious which will be the more economical plane for 1 to 3 hour missions. As a Pratt fan, how do I loose?

195-E2, CSeries, 320 and 737 nowadays have the same wing span give and take a foot or two, That makes them fit into an ICAO code C airport gate which accepts planes up to 36m wing span.
Amazing to have two new entrants in that space.
Actually, with the C919 and MS
-21, it will be a very crowded field. Will anyone make a profit in narrowbodies? So far, I only see the A321NEO having an uncontested space and the CS300 having a low enough cost per flight and low enough CASM to thrive. But only if the C-series sells a few hundred more. Economies of scale will drive this sector. Embraer has sold 325 E2-jets as well as a significant number of the original e-jets that have given them economy of scale.
Interestingly, the sum is officially the same, but Bombardier is at 285 (after removing Frontier's orders).
I am personally surprised how well the CS100 has done. It gives me reason to believe it will continue to do well.
