Introduction
August04, 2016, ©. Leeham Co: With the classification of the Irkut MC-21-300 done in terms of its size segment (it’s close to the Boeing 737 MAX 9 in size) and the key data of the aircraft analyzed, it’s now time to look at aircraft efficiency and payload-range performance.

We will do this with two cabin configurations for the aircraft. The first will be the nominal two class seating as proposed by the OEMs. For the second, we use a single class layout with 30-inch seat pitch.
Summary:
- The MC-21 has problems to compete with the re-engined 737 MAX 9 in terms of efficiency when using the standard two class cabins.
- When we switch to a single class high density layout, the fuel efficiency improves. The MC-21-300 exit concept is then more similar to the MAX 9, which affects efficiency in a positive way.

Introduction
August 01, 2016, ©. Leeham Co: After having found the nearest competitor to the Irkut MC-21-300 as the Boeing 737 MAX 9 in our first article, we now go deeper in the comparison of the two aircraft.

In the first article, we found that the aircraft have almost identical cabin dimensions. Now we will look at other areas like airframe dimensions, weights and data which dictate overall performance.
Summary:
- The MC-21 has cabin dimensions which are very close to the 737 MAX 9.
- The nominal two class seating by Irkut is lower than the MAX 9. We have assumed that this will increase during the lifetime of the MC-21.
- We also compare other data between the MC-21-300 and the MAX 9, such as weights, wetted areas and effective wingspans to see if these are similar as well. In the end these dictate the aircraft’s efficiency together with the engines.

Introduction
July 28, 2016, ©. Leeham Co: In February we did a first analysis of the new Irkut MC-21 single aisle aircraft that Russia is developing. We found that the aircraft has its own profile; it’s not a copy of a Western design. Irkut is the company within Russia’s United Aircraft group which is developing MC-21 (or rather, its design bureau, Yakovlev, is). Irkut has also gone its own way in sizing the aircraft.

In our February analysis, we found that the first aircraft being developed, the MC-21-300, is larger than both the Airbus A320 and Boeing 737 MAX 8, the present top sellers in the single aisle market. At the time, we decided to analyze the aircraft which was closest to those two in size, MC-21-200, which is the second variant in development. We will now look at the larger MC-21-300 (Figure 1), the aircraft which rolled out in June and which will fly early next year.
Summary:
- The MC-21 has its own profile; it is not a copy of a Western aircraft. It has a wider cabin than the A320 and a higher capacity in its base variant, the MC-21-300.
- The MC-21-300 is smaller than an A321. It most closely resembles a Boeing 737 MAX 9 in size. We will therefore conduct the analysis of the MC-21-300 by comparing it to the largest Boeing MAX variant.
Interview with Rob Dewar: CSeries in service reliability

Introduction
21July 2016, ©. Leeham Co: Bombardier”s CSeries project has passed one hurdle after another during its development. The last one was the lack of Marquee customers on top of launch customer SWISS. This has now been solved with large orders from Air Canada and Delta Air Lines.
There is one hurdle remaining: what will be the aircraft’s reliability when it enters into service (EIS)?. We did the EIS interview with CSeries VP and program manager Rob Dewar only two days before the CS100 aircraft would fly its first operational sectors with Swiss last Friday. This autumn, airBaltic will put the larger CS300 into service.

Summary
- The CSeries has been designed for in service reliability from the outset of the project.
- Systems and solutions have been primarily chosen for the in-service maturity on other platforms.
- Any deviation from this philosophy, like for Fly-By-Wire, Geared Turbo Fan or Electrical brakes, requires that the technology earn its place in the project by bringing unique advantages.
Airbus’ Leahy shifts a bit on MOM aircraft

July 14, 2016, © Leeham Co., Farnborough Air Show: Basking on an order for 30 A321LRs on the final day of the Farnborough Air Show, Airbus’ top salesman said the Middle of the Market sector stops at 240 passengers and it’s best served by a single-aisle aircraft.
John Leahy, Chief Operating Officer-Customers, said twin-aisle aircraft down to 240 or even 220 passengers don’t work economically against a single aisle. The A321LR (Long Range) seats a maximum of 240 passengers and it is single-aisle. Even though Airbus has a 250-seat A330-200R (Regional) and an A330-800 (7,200nm-plus range), Leahy didn’t attempt make a case that these aircraft are suitable for the MOM sector.
Summary
- A 767-200/A310 size replacement isn’t viable.
- Boeing’s 20-year market forecast for the mid-sized twin-aisle is for consumption for the Board of Directors.
- The A330-200R and A330-800 aren’t good MOM aircraft.
Bombardier sees more C Series orders this year

July 10, 2016, © Leeham Co., Farnborough Air Show: Winning major orders from Air
Fred Comer, president of Bombardier Commercial Aircraft.
Canada and Delta Air Lines earlier this year and the entry into service of the CS100 this Friday with launch customer Swiss International Air should give Bombardier’s bet-the-company gamble a boost for more orders this year.
This is the prediction by Fred Comer, president of Bombardier Commercial Aircraft.
During an interview with LNC on a media demo flight of the CS100 at the Farnborough Air Show, Comer said the smaller BBD can compete with the behemoths Airbus and Boeing for orders in the 125-150 seat sector.
Summary
Comer says:
- Boeing’s prospective 737-7.5 still won’t be competitive.
- The CS100 is better than the Embraer EJet-E2.
- Embraer’s complaints of unfair competition because of Canadian government investment are unfounded.

program is going well, with the company looking for ways to add improvements to the airplane even before it enters service next year.
Improvements, which include airplane and engine components, are intended to provide dispatch reliability close to the 99.98% of the 737 NG and extend on-wing time for the reliable CFM56 engine that has powered the 737 since introduction of the 737-300 in 1984, says Keith Leverkuhn, VP and GM of the 737 program.
Summary
- Many of the major tests are completed.
- Boeing, CFM see opportunities to insert components into the LEAP-1B during flight testing to extend on-wing time from entry-into-service.
- MAX 7X (or “7.5”) can be done within the “confines” of the current MAX program.
- A larger MAX isn’t ready to go yet.
Farnborough Air Show preview: expectations and possible surprises
Subscription Required
Introduction
July 4, 2016, © Leeham Co: The Farnborough Air Show begins next Monday and predictably, focus will be on orders.
With new airplanes from Airbus and Boeing past their development stages, conventional wisdom says there won’t be much new in this arena.
Don’t be so sure.
Bombardier is now on an upward trajectory, but don’t look for a big splash at #FIA16 (for those looking for this year’s Twitter handle). Embraer will have its E190-E2 at the show.
It’s Boeing’s 100th Anniversary and the company is rolling out the history for the show.
Summary
- No new products from Airbus.
- Boeing may have a surprise.
- Low number of orders anticipated.

Introduction
John Schmidt of the consulting firm Accenture, wearing smart glasses for augmented reality.
June 27, 2016, © Leeham Co.: The Farnborough Air Show (FIA16) is closely watched for orders placed with Airbus, Boeing and to a much lesser extent, Bombardier and Embraer. Orders are the headline grabbers and are viewed as indicative to the health of commercial aviation going forward in the near- and mid-term.
But the consulting firm Accenture, in an interview with LNC says there are other benchmarks to watch for at FIA16.
Summary
- A large number of new entrants into aerospace is competing for engineering talent, and it’s not the conventional suspects.
- Execution will be of greater importance than new products.
- The ascent of disruptive technologies; and
- Doubling down on data deluge.
Dearth of wide-body order hang over Airbus, Boeing

Introduction
July 25, 2016, © Leeham Co.: It wasn’t a good two weeks for wide-body airplanes.
Airbus, responding to a leak to the Paris newspaper La Tribune, confirmed it will reduce production for the A380 from 20/yr in 2017 to 12/yr in 2018—returning the program to a loss.
Boeing firmed up an MOU announced at the Paris Air Show with Volga Dnepr for 20 747-8Fs, but wouldn’t say how many are firm orders and how many are options.
Week 2: Boeing took nearly $1.7bn in after-tax write downs for the 787 and 747-8 programs.
And, while not directly tied to wide-bodies per se, Delta Air Lines announced it will reduce its trans-Atlantic services for a variety of reasons. Most of these services are performed with wide-body aircraft.
