Paris Air Show Preview

Introduction
May 22, 2017, © Leeham Co. The Paris Air Show begins June 17, and few in the industry expect much in the way of orders this year.
The order cycle is on the downward side of the bell curve. Sustaining the 2,000, 3,000 or nearly 4,000 gross orders announced 2011-2013 simply couldn’t be achieved. The “order bubble” had to break, and it did. Last year, Airbus and Boeing reported some 1,400 orders between them.
Airbus guides that it will tough to achieve a 1:1 book:bill this year. Boeing is running about 1:1 book:bill so far but it also guides conservatively. Still, LNC thinks Boeing might surprise this year–and some of this could be at the Paris Air Show.
Leeham Co.’s new publication, Commercial Aviation Report, provides a Focus Report on the Air Show. This encompasses the expectations for Airbus, Boeing, Bombardier, Embraer, COMAC, Irkut, Mitsubishi, CFM, GE Aviation, Pratt & Whitney and Rolls-Royce into one easy-to-read package.
The pre-airshow press briefings by the OEMs begin next week. We don’t expect any earth-shattering news from these and we wanted to get our views out ahead of these briefings.
Summary
- Boeing wants to launch the 737-10 MAX at the Paris Air Show. This could spur a group of orders that would give Boeing a rare win in the headlines vs Airbus on the latter’s home ground.
- Mitsubishi plans to have its MRJ90 at the Air Show. One airplane entered the paint shop for ANA colors–this might be the one making the appearance.
- Embraer expects to have its KC-390 there. Will the E195-E2 also make an appearance?
How Airbus can kill the Boeing 797

May 10, 2017, © Leeham Co.: Airbus can kill the business case for the prospective Boeing 797, the New Midrange Aircraft also known as the Middle of the Market Airplane,
- Reuter’s Tim Hepher has this story.
- CNN’s Jon Ostrower has this story.
All it has to do is move first, instead of waiting for Boeing to launch the 797, something considered likely next year.
If Airbus launched what is commonly called the A322, a larger, longer-range version of the A321neo, the new version would become a true replacement for the Boeing 757, meet economics of the smaller 797, which has a working title of the 797-6, at a much lower capital cost.

Introduction
April 27, 2017, © Leeham Co.: We have in several articles gone through the sizing of an NMA (New Midrange Aircraft). We looked at the fuselage, cabin, wings and engines. Now we will sum the exercises and look at the performance of the resulting aircraft.
Boeing is seriously considering launching an NMA. The key to the launch decision will be the airplane’s economics: for development and production as well as operation.
The idea is the NMA shall have “twin aisle comfort with single aisle economics.” We will now use or performance model to analyze if the final aircraft has these characteristics.
Summary:
- An NMA designed to the principles in our articles will have a seven abreast dual aisle cabin. The cabin will increase passenger comfort in the 200 to 260 seat range and speed ground operations.
- Careful design of the fuselage, paired with a modern wing and engines, would produce an NMA with “dual aisle comfort and single aisle economics.”

Introduction
April 20, 2017, © Leeham Co.: After defining the fuselage and wings, it’s now time for the engines. We go through the sizing criteria for engines for airliners and find the size of engine that is needed for the NMA.
The NMA will need engines which are larger than the single aisle engines for Airbus’ A320neo and Boeing’s 737 MAX. But they will be smaller than the next size up for modern engines, the GEnx-2B for Boeing’s 747-8.

This means the NMA will need new engines, at least 50% larger than the present engines designed for A320neo and 737 MAX.
Summary:
- An NMA engine will be sized by V2 safety speed or Maximum Continuous Thrust (MCT) criteria.
- The normal Top of Climb (ToC) sizing point will be less stressing for a twin engine airliner like NMA.
Asian airline shift portends big ramifications

Introduction
April 17, 2017, © Leeham Co.: A shift is underway among Asian airlines that could have ramifications for the airframe and engine manufacturers and, by extension, their suppliers.
It doesn’t appear, however, that aerospace analysts in the US and Europe realize this shift. At least none has written about it that we’ve seen among the research notes we receive.
Summary
- The creation of the Value Alliance of Low Cost Carriers brings together eight LCCs under one alliance.
- AirAsia faces a competitive threat.
- Full service carriers also face a threat, particularly those in Japan, concludes one aerospace analyst team in the region.
- Airbus, Boeing have a backlog of more than 1,000 airplanes with the VALCC group and hundreds more with other airlines.

Bjorn’s Corner: Aircraft engines, sum up
By Bjorn Fehrm
April 14, 2017, ©. Leeham Co: We’ve been talking engines on Fridays since October 2016. The Corners covered several areas, from technologies to operations.
And we could go on and dig deeper. But we will move on.
Before we go, we sum up what we have learned in the 24 Corners around airliner Turbofans.

April 7, 2017, ©. Leeham Co: Last week’s Corner developed the overhaul shop visits per year for wide-body engines. We will now look at how the market develops around these overhaul opportunities.
How does the shop structure develop over a popular engine’s life-cycle? How much choice has an operator and when?

Bjorn’s Corner: Aircraft engine maintenance, Part 5
By Bjorn Fehrm
March 31, 2017, ©. Leeham Co: In the last Corner, we showed flight hour graphs for wide-body engines. Now we will deduce the market for engine overhauls from these graphs.
It will show which engines are still in engine manufacturer care, in their main maintenance cycle and in the sun-set phase.

The phase the engine is in and its future flight hour development will decide the attractiveness of the engine for overhaul organizations. Read more
Bjorn’s Corner: Aircraft engine maintenance, Part 4
By Bjorn Fehrm
March 24, 2017, ©. Leeham Co: After covering the maintenance market for single-aisle engines, time has come for the engines used on wide-body aircraft. The engine maintenance for a wide-body engine is a bit different to the single-aisle engine. The difference is caused by the longer flight times for the wide-bodies. This makes the flight time wear a more dominant maintenance driver than it is for the single-aisle engines.
The changes in overhaul work caused by the difference in flight profiles and the lower number of engines in the market (compared to the single aisles) will affect how the overhaul market is structured and who are the dominant players.

Bjorn’s Corner: Aircraft engine maintenance, Part 3
By Bjorn Fehrm
March 17, 2017, ©. Leeham Co: In the last Corner, we showed graphs of the yearly flight hours for engines on single-aisle aircraft. Now we will deduce the market for engine overhauls from these graphs.
These will show which engines generate a maintenance volume that is interesting for engine overhaul companies and which engines are niche.

Based on the market size, we will then go through how an engine is maintained when new, mature and at end-of-life.
