Rolls cites timing, analysts cite poor financial condition for NMA withdrawal

Introduction
March 4, 2019, © Leeham News: Rolls-Royce last week announced it had withdrawn from competition for the Boeing NMA engine provider, citing a 
mismatch in timing between its Ultra Fan being ready and Boeing’s desired entry into service.
Warren East, the RR CEO, glossed over other reasons, but they were there: the program making commercial sense and the impact of the Trent 1000 engine challenges.
Aerospace analysts interviewed by LNA and whose research notes were provided have other reasons.
Summary
- After dissecting RR’s financial statements, with special charges, accounting changes and Free Cash Flow analysis, some analysts concluded the company simply doesn’t have the money to develop the engine for the NMA.
- Although CEO East glossed over the Trent 1000 issues, some analysts feel this was more important than let on.
- CFM, according to one analyst (and many observers), believes it is the favorite for the NMA engine selection, so RR bowed out.
Pontifications: Doubts continue over Boeing NMA launch
March 4, 2019, © Leeham News: Another week, another NMA story.
For an airplane that doesn’t exist, the prospective Boeing NMA continues to dominate much of the aerospace news.
By Scott Hamilton
Last week’s announcement by Rolls-Royce that it withdrew—in December, as it turns out—from the competition to power the NMA prompted a flurry of stories in aerospace media, including LNA.
Some stories suggested RR’s withdrawal meant Boeing was getting closer to launching the airplane.
Boeing, in January, said Authority to Offer might come this year and program launch had moved from 2019 to 2020.
Two prominent consultants predicted at the Pacific Northwest Aerospace Alliance conference last month the odds were 60-40 or 65-35 Boeing would proceed.
Maybe, but I have to tell you that conversations I had last week in the wake of the Rolls announcement are not encouraging.
Bjorn’s Corner: Yaw stability, Part 2
By Bjorn Fehrm
March 01, 2019, ©. Leeham News: We now continue our discussion of the yaw stability of an airliner.
Last week we defined the basic conditions of yaw stability. The aerodynamic side force from an angled airflow stemming from an aircraft yaw angle or sideslip must be higher behind the center of gravity than ahead of the center of gravity.
This is why aircraft have a large vertical wing at the rear of the aircraft called the vertical tailplane. Figure 1.

Transcript: RR told Boeing before end of 2018 it’s out of NMA competition
Feb. 28, 2019, © Leeham News: The announcement today by Rolls-Royce that it has withdrawn from the competition to provide an engine for the Boeing New Midmarket Airplane came as a surprise.

This leaves CFM and Pratt & Whitney as the remaining competitors.
RR’s withdrawal wasn’t the only surprise.
CEO Warren East revealed Boeing had been notified shortly before the end of 2018.
Shareholders OK Boeing-Embraer JV; court, anti-trust approvals next

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
Subscription Required
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.
Boeing supplier reaches deal with Machinists Union
By Bryan Corliss
February 19, 2019, © Leeham News: Machinists Union members who work at Cadence Aerospace-Giddens in Everett, WA, voted overwhelmingly to approve a new three-year contract with the company.
Ninety percent of those who voted Monday were in favor of the deal, according to the IAM’s District 751. (IAM 751 typically does not release vote totals in its contract elections, only the percentage voting in favor or against.)
IAM 751 President Jon Holden called the contract a “positive agreement.” The union’s negotiating committee called the deal “one members can be proud of and can continue to build upon into the future.”
