October 13, 2016, ©. Leeham Co: The airline engine industry is like a ticking bomb. Over the years, a business practice of selling the engines under manufacturing cost and planning to recover costs and make a profit on the aftermarket developed. This goes back decades.
The practice was fostered by fierce competition over the engine contracts for aircraft which offered alternative engines. The losses of the engine sales could be made up later by selling spare parts and services at high margins.
These “jam tomorrow” practices have several implications. The engine industry is now confronted with these and wonder how it could put itself in such a bind. How to handle these and what is the way back?

Introduction
September 29, 2016, ©. Leeham Co: We will now finish our series about the Russian-Chinese wide-body with looking at who will have what role in the program.
As we described in the initial article, “Background and outlook,” Russia and China have vastly different competencies when it comes to making a state of the art wide-body aircraft.
Russia has made airliners since the 1930s, including wide-body jets. China did not design its own jet aircraft (military or civil) until the mid-1980s. Most of the aircraft produced still today in China have their origin in Russian designs.
At the same time, we saw in the article about the market demand for the aircraft that the Chinese market is 90% of the home market. This makes for China demanding important parts of the aircraft’s production, and China has the money to invest in production facilities.
All this will influence how different parts of the project will be shared between Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC).

Introduction
September 19, 2016, ©. Leeham Co: In Part 4 of the article series, we put together an assumed complete Chinese-Russian wide-body aircraft with fuselage, wing, engines, etc. It is now time to understand what kind of performance that can be expected, given the data we have from the wide-body partners, Russia’s United Aircraft Corporation (UAC) and the Commercial Aircraft Corporation of China (COMAC).
We will combine these data with the ones we have deduced as plausible to fill the gaps, given the time frame and technology level that UAC and COMAC intend to use.
Out will come a first estimate of what kind of performance such an aircraft can have in terms of efficiency and payload versus range capability.

Introduction
September 15, 2016, ©. Leeham Co: In Part 3 of this series, we identified the type and size of wing we would have on a new Russian-Chinese wide-body. It’s now time to go through all the considerations around the engines for the aircraft.
The aircraft would enter the market around 2025. We would have to decide on what size engine that would be needed, what engines would be available at the time and could this project motivate any new engine developments.

Sept. 12, 2016, © Leeham News: Boeing is on a transition to improve manufacturing efficiency that will take years to complete.
Dominic Gates of The Seattle Times Sunday provided a detailed comparison between the Airbus wing production plant in Broughton, Wales, and Boeing’s 777X wing production plant in Everett (WA).
The Broughton facility is a unit of ElectroImpact of Mukilteo (WA), next to Everett’s Paine Field, where all of Boeing’s wide-body assembly is done. ElectroImpact also is a supplier to Boeing.
Boeing is also adding robotics to the 777 Classic assembly process, from wing-painting to riveting. The latter has some glitches, Gates recently reported. Boeing officials blame delays and traveled work on a three-month strike by supplier Triumph Group. The robotics on the Classic are getting their baptism in advance of becoming the principal method of assembly on the new 777X, which begins in 2018.
Finally, or perhaps not, Boeing began a transition to more automation with the assembly of the 737 MAX. A dedicated, third assembly line was created for the MAX that includes more efficiencies.

Introduction
September 08, 2016, ©. Leeham Co: Having covered the possibilities of reusing parts of the Il-96 fuselage for a new Russian-Chinese wide-body, it’s now time to look at the existing IL-96 wing and how far this is from a modern design.
The intent is not to propose that the existing wing is reused but rather to check the technology level against western designs and how big a leap it will be for the partners to make a modern high performance wing for the aircraft.

Introduction
Sept. 5, 2016, © Leeham Co.: The semi-annual update to The Guide, from appraiser Aviation Specialists of Herndon (VA), indicates Airbus and Boeing single-aisle aircraft remain hotly competitive in current market values and future residual values.
The Guide covers all in-production jets from Airbus, Boeing (including McDonnell Douglas), Bombardier and Embraer, plus their out-of-production airplanes. Passenger and freighters, including some P2F conversions, are included. BBD’s CS300 is included, although it doesn’t enter service for another few months.
The Guide is a for-purchase product.

Introduction
September 01, 2016, ©. Leeham Co: In Part 1, we concluded that the existing Il-96 fuselage cross section would be suitable for a new Russian-Chinese wide-body. This means that a lot of experience and existing designs for fuselage sections can be re-used.
Most importantly, it means that mock-ups and cabin sections can be made early in the project to start work on new and better cabin equipment. This is an area where the partners really lag their western competitors.
We will now look at what aircraft capacities can be conceived with the existing Il-96-300 and -400 fuselages and what changes will be necessary to achieve the targeted sizes that Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China (COMAC) have communicated.
