Dec. 5, 2016, © Leeham Co.: Far be it from me to say, I told you so.
But I did.
When Washington State extended the Boeing 787 tax breaks in November 2013 to the 777X through 2040, I wrote and told everyone who would listen (and even those who wouldn’t) that the 787 tax breaks had been found illegal. So extending them was extending illegal tax breaks.

December 02, 2016, ©. Leeham Co: We will now look at the combustor area in our series on modern turbofan engines. There is a lot of activity in this area, as it sets the level of pollution for the air transportation industry for some important combustion products.
We will also finish off the compressor part of our series by looking at the bleeding of cooling air for the engine and for servicing the aircraft with air conditioning and deicing air.

The amount of air which is tapped from compressor stages for cooling and other purposes can exceed 20% of the core flow (some of the flow paths are shown in Figure 1). At that level, it has a marked influence on the performance of the engine. Read more

US Sen. Jeff Sessions (R-Alabama) is President-Elect Donald Trump’s choice for US Attorney General. He’s a close ally of Airbus. Photo via Google images.
Nov. 29, 2016, (c) Leeham Co.: When it comes to the prospect of imposing trade sanctions or retaliatory tariffs on Airbus for airplanes ordered by US customers, the European manufacturer has some advantages over Boeing few people apparently have thought about.
One is called Alabama. It’s where Airbus is producing A320 family members for US customers.
Alabamans voted by 1.76-to-1 for Donald Trump. Sixty-three percent to 35%.
Donald Trump tapped Sen. Jeff Sessions of Alabama to be his Attorney General. Sessions was one of the first in Congress to endorse Trump. He served as an advisor throughout the campaign.
Sessions is a big supporter of Airbus.
Sen. Richard Shelby, the other Alabama Senator in Congress, is also a big supporter of Trump. And of Airbus.
It’s highly likely that Sessions and Shelby will bend Trump’s ear in favor of not levying tariffs on Airbus planes.
Nov. 28, 2016, © Leeham Co.: Airbus claims that in a huge blow to Boeing and Washington State, the World Trade Organization (WTO) ruled today that the $8.7bn tax subsidy package Gov. Jay Inslee and the state Legislature approved for the 777X program is a “prohibited subsidy.”
This is the most onerous finding of illegal subsidies under WTO rules, and one that is rarely determined.
Boeing said the WTO “today rejected virtually all of the European Union’s challenges to the Washington state tax incentives” and declared a “complete victory.”
Nov. 28, 2016: Here are the full statements from Airbus and Boeing about the WTO ruling today finding Boeing received prohibited subsidies from Washington State for the 777X development:
Nov. 28, 2016, © Leeham Co.: Boeing last week named an outsider, Kevin McAllister, as the chief executive officer of Boeing Commercial Aircraft (BCA).
I think this has the potential to be an invigorating move.
McAllister comes to BCA from his position as CEO of GE Aviation Services.
I don’t know McAllister and have no opinion whether he will be good, bad or mediocre. But I do like the idea of bringing an outsider in to run BCA. (My insider favorites were Stan Deal and Beverly Wyse.)
Here’s why.

23 November 2016, ©. Leeham Co: Emirates Airline president Tim Clark says the carrier “has to change its approach to long-haul pricing to combat increasing competition” after presenting a half year 2016 profit which plunged 64% on 9 November.
The reason is that traditional mainline carriers are entering the low-cost, long-haul market in addition to the established LCC entrants: Norwegian Air Shuttle, AirAsiaX and Wow Air.
Emirates will add new low-cost fares to keep its growing fleet of Airbus A380 and Boeing 777 filled. Clark states this is necessary and that the airline will not back down on its plans for additional aircraft. It will be a period “of fierce competition as more and more international network carriers are entering low-cost, long-haul,” declares the COO.
What has changed? Isn’t Emirates the Kings of competitive long-haul travel? Read more

Introduction
November 21, 2016, ©. Leeham Co: The emergence of Boom Technology and Virgin Atlantic’s plans to offer supersonic business class passenger traffic over the Atlantic is intriguing.
Enough of the business plans and data around the aircraft are known to enable us to do a first economic analysis.
There will have to be a lot of assumptions in such an analysis but having modeled around 100 different airliner types economics’, we have some data to base our assumptions on.
We think the accuracy will be enough to get a first feel if the Virgin Atlantic venture is tight on margin or a slam dunk (should it become reality).

Nov. 17, 2016, © Leeham Co.: The deferral by United Airlines of 65 Boeing 737-700s announced Tuesday caused some observers to conclude this has a negative impact on the manufacturer, but this may well overlook a larger issue.
UAL is the latest “quality” airline to announce deferrals to reschedule capital expenditures or because of not needing the aircraft now.
Softening yields, particularly among US airlines, indicate over-capacity despite load factors of 85% or more, say industry observers.
While the backlogs of Boeing and Airbus remain solid today, do the actions of several major airlines indicate the leading edge of a global economy that’s beginning to soften?
