June 1, 2017, © Leeham Co.: Pratt & Whitney, like the airlines, lessors, suppliers and competitors, awaits a decision by Boeing whether it will launch the New Midrange Aircraft for the Middle of the Market sector.
PW’s president, Bob Leduc, said the company is going through its business case studies

even as it provides information to Boeing.
In an interview yesterday with Leduc and PW Commercial Engines president Chris Calio at PW’s pre-Paris Air Show media days near its West Palm Beach (FL) engine production facility, Leduc says the market size and the assumption Boeing will choose two engine makers to power the NMA are among factors that will drive the business case.
Here is a transcript of the interview on the NMA and other topics. The lead into the NMA evolved from a question about the aftermarket services PW—and Boeing—have as strategic profit-center goals.
May 15, 2017, © Leeham Co.: It was a busy news week last week.
Let’s look at these events.

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.

May 01, 2017, ©. Leeham Co: The COMAC (Commercial Aircraft Corporation of China) C919 is expected to have its first flight this month, perhaps as early as this week. We review where the program stands and how it compares to its competition.
When the C919 program was launched in 2008, neither Airbus nor Boeing envisioned re-engining the A320 and 737 families. First flight was planned for 2014 and entry-into-service in 2016.
The C919 would have had economic and capital cost advantages over the A320 and 737NG. With program delays of at least four years, and maybe more, those advantages have been narrowed. Read more

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.

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.

April 19, 2017, ©. Leeham Co: In our second article about Aeroflot, the Soviet Union flag carrier that transformed to a modern airline, we will cover the period from the fall of the Soviet Union until 2010.
This was the difficult period for all participants. The old structures no longer existed and were replaced with… nothing, followed by uncertainty and a long struggle to get back to normal.
Boeing-Bombardier complaint could affect competition in coming Delta neo-MAX RFP
Commentary
May 1, 2017, © Leeham Co.: Boeing’s complaint against Bombardier’s CSeries transaction with Delta Air Lines, and a request for millions of dollars in antidumping and penalties might be coming at a bad time.
Was the Boeing 787 program marked by “launch customer pricing” or “dumping”? This may depend on program or unit accounting. Boeing photo.
“Boeing requests that the Department initiate an antidumping investigation and impose antidumping duties on Aircraft from Canada in an amount sufficient to offset unfair pricing above.”
If Boeing is successful in its request of the US government and International Trade Commission to impose duties before the first CS100 is delivered to Delta next year, the cost of the airplane will balloon from the $19.6m Boeing calculates (and which BBD denies) to at least $33m.
It’s unclear from the complaint who would pay this penalty—Bombardier, maintaining the price to Delta, or would Delta have to pay the reset price?
Regardless, this kerfuffle can’t be welcome news to Delta, which already has a ruffled relationship with Boeing due to its opposition to the ExIm Bank and orders for Airbus aircraft.
