Shareholders OK Boeing-Embraer JV; court, anti-trust approvals next
Subscription Required
Introduction
Feb. 28, 2019, © Leeham News: Embraer’s shareholders this week approved the joint venture between their company and Boeing, moving another step closer to completion expected by the end of this year.
Boeing will own 80% of the new company and have governance control; Embraer will own 20%.
The shareholders’ action comes after a Brazilian court for the fourth or fifth time enjoined the companies from proceeding with negotiations. Higher courts overturned each previous injunction and will likely do so again.
Global regulatory anti-trust reviews are the step. All decisions are expected by year end.

John Slattery, CEO of Embraer Commercial Aviation, gave this take on the pending joint venture in his column on LinkedIn.
Summary
- “NewCo” will be based in Brazil and be responsible for Boeing’s commercial airplanes up to 150 seats.
- A second joint venture is planned for military development.
- The KC-390 is a focus of the second JV.
Airbus appears poised to launch A321XLR

Introduction
Feb. 25, 2019, © Leeham News: The longer Boeing dithers on launching the New Midmarket Airplane, the harder it is to close an already difficult 
business case.
News last week that Airbus finally, at long last, is appears about to launch its Xtra Long Range A321XLR this year is overdue. Doing so will make Boeing’s NMA business case more difficult to close.
The aircraft should have been launch in late 2017, an insider told LNA recently. But the corruption scandals enveloping Airbus disrupted plans and drove executives to indecision. Launching the A321XLR was put on hold.
Summary
- Killing the NMA.
- A321XLR details.
- Narrow market.
- Engine down select soon.
Pontifications: March is a critical month for engine OEMs
By Scott Hamilton
Feb. 25, 2019, © Leeham News: Even as Boeing put off a decision whether to launch the New Midmarket Aircraft until 2020, next month could be an important milestone—not only for the program but especially for the engine makers.
Unless delayed, engine down-select is supposed to be made in March.
This is a critical decision that could have huge implications to one of the engine OEMs—Rolls-Royce.
Bjorn’s Corner: Airliner yaw stability
By Bjorn Fehrm
Feb. 22, 2019, ©. Leeham News: After discussing an airliner’s pitch stability we now turn to the yaw stability. A stable aircraft in yaw means we don’t want the aircraft to wag its tail sideways while flying.
The airliner shall fly straight ahead during take-off, climb, cruise, descent and landing, even when we have problems with an engine and must throttle it back or shut it down on one side.

Airbus, Boeing pause on some production rate hikes
Subscription Required
Introduction
Feb. 21, 2019, © Leeham News: Airbus is boosting the A320 production to 60/mo this year and 63/mo next year.
But it’s put a pause on increasing the A350 rate from 10/mo to 13/mo.
Boeing was widely expected to follow its planned 737 rate hike of 57/mo, from this summer, to 63/mo next year to keep up with demand and with Airbus.
However, on the sidelines of the annual Pacific Northwest Aerospace Alliance conference last week, LNA learned that a 737 rate hike to 63/mo has been apparently put on a pause. Although Boeing has not made a decision to go to rate 63, the hike was expected in 2021, according to suppliers. This is now showing as 2022, they said.
Summary
- Airbus, Boeing backlog for single-aisle airplanes extends years.
- Both have ramped up production to meet demand, create delivery positions.
- Supply chain struggles to keep up.
- Twin-aisle demand waits for replacement surge.
A380 end opens opportunity for A350-2000

Introduction
Feb. 18, 2019 © Leeham News: Airbus’ decision to end the A380 program clears the path, if chosen, for a plane that was studied three or four years ago: the stretch of the A350-1000 to the size of the 777-9.

A 400+ passenger “A350-2000” would have encroached too closely on the A380’s 500+ passengers. Officials feared the A350-2000 would hurt the sales prospects of the A380.
With the A380’s last delivery now planned for 20xx, this becomes a moot point.
The prospect of a new, Rolls-Royce Ultra Fan engine for the A350 around 2025 will give the -2000 significantly superior economics to the 777-9 and a longer range, a preliminary analysis by LNA shows.
Summary
- An A350-2000 with RR Ultra Fan engines is superior to the 777-9.
- However, Boeing has a big head start with orders for 340 777Xs, most of which are for the -9.
- The market demand for a 400-450 seat airplane is increasingly iffy.
- But the A350-900/1000neo helps business case.

Pontifications: Which airplanes are revolutionary or evolutionary?
By Scott Hamilton
Feb. 18, 2019, © Leeham News: Last week’s column about the revolutionary Boeing 747 prompted some Twitter interaction asking what other commercial airplanes might be considered “revolutionary.”
I have my views. Let’s ask readers.
There are also three polls below the jump in addition to the usual comment section. Polling is open for one week.
Bjorn’s Corner: Pitch stability, Part 10. Wrap up.
Feb. 15, 2019, ©. Leeham News: We now summarize the problems around an airliner’s pitch stability and why a good pitch stability is so important before we go to the next subject, yaw stability.
The pitch stability and how it works in different parts of the flight envelope is the trickiest of the aircraft’s stability problems around its three axes; Pitch, Yaw and Roll. Here is why.

A380 launch aid in limbo at WTO, member states following program termination
Feb. 14, 2019, © Leeham News: Termination of the A380 program leaves unanswered Airbus’ obligation of outstanding launch aid from France and Germany.
But apparently it removes any overhang of this aid in the long running trade dispute between the US and Europe (Boeing vs Airbus) at the World Trade Organization.
As the dispute wound its way through the WTO since the US filed its complaint nearly 15 years ago, the only surviving issues were subsidies for the A380 and A350.
Based on precedent involving termination of the A340 program, in which the WTO ruled there was no further harm to Boeing once the last A340 was delivered, the remaining launch aid was rendered moot in the context of the WTO. The governments wound up eating the balance of the launch aid.

Launching the NMA could mean new business model for Boeing
By Dan Catchpole
Feb. 14, 2019, © Leeham News: Commercial aerospace’s super cycle is alive and well—and looks to keep going through the foreseeable future. Major suppliers and OEMs, and industry analysts at the Pacific Northwest Aerospace Alliance annual conference are all optimistic about the industry demand. Analysts noted potential concerns, such as a trade war with China, a catastrophic terrorist attack, or an economic shock. However, even the often bubble-bursting Richard Aboulafia, an aerospace analyst and vice president at the Teal Group, said the party likely will keep rolling on for several years more.
Amid such a sunny forecast, Boeing is weighing whether to overhaul its commercial aerospace business model, said Kevin Michaels, a co-founder of AeroDynamic Advisory.
The company is working to close the business case on a new midmarket airplane (NMA), already dubbed the 797 by industry watchers. The NMA—or, if Boeing does not launch it, then its next single aisle airplane—likely will usher in “the next evolution of the jetliner business model,” Michaels said.
The new model, he said, has four key aspects:
- Greater vertical integration and in-sourcing work;
- Targeted, yet aggressive expansion of services;
- Redefining supplier relationships to capture more aftermarket revenue; and
- Introducing model-based systems engineering.
