Introduction
July 28, 2015: © Leeham Co. Trying to decipher what the airframe Original Equipment Manufacturers (OEMs) are going to do is a sporty game that is often analogous to Kremlin watching, especially when it comes to Airbus and Boeing.
The OEMs are naturally circumspect about most everything they do: product development, aircraft pricing, sales campaigns, etc.
They also often are like lawyers when it comes to promoting their products in the public domain: cherry-pick the data that supports your product and which puts your competitor’s product in the worst possible light.
Aerospace analysts, consultants and media (as well as the enthusiast) look anywhere and everywhere for information to discern what the OEMs are up to or how the airplanes are performing or whatever the soup de jour is.
There is more information in the public domain than you would think.
Boeing 777X heading towards design freeze a bit heavier than planned.

Introduction
July 12, 2015, © Leeham Co. As we reported from Boeing’s Paris Air Show briefing, Boeing’s 777X project is progressing to a design freeze later in 2015. At the briefing everything was presented as being on track with no changes of key data. There have been signs that this in not fully the case. The 777X program is suffering the same disease that hits other aircraft programs, weight gain flu.
To understand it better, we compiled the many indications that points to weight increase and ran them through our proprietary model to understand why and see what it means for the aircraft’s performance.
Summary:
- Weight increase is an evil that all aircraft programs battle with. Our analysis shows that 777X is no different.
- Engine thrust is one of the areas which will be increased to mitigate increased weight. We give the latest status of GE9X thrust development, now beyond 105,000 lb.
- A number of airframe changes have been made. We analyze their consequences and make predictions for future maximum weight increases.
LEAP, the best of 1,000 investigated alternatives.

Introduction
June 23, 2015, © Leeham Co. CFM International went through 1,000 iterations before settling on the final design for the LEAP engines that will power the Airbus A320neo, the Boeing 737 MAX and the COMAC C919.
In an interview with us at the Paris Air Show, CFM LEAP program manager Gareth Richards explained the macro process of the development of LEAP, CFM’s sequel to CFM56. This will be the largest turbofan engine program in the history of civil aviation and the follow on to the world’s most-sold turbofan, the CFM56.
Richards focused on how an engine like LEAP gets designed and what the trades are that a single aisle, short haul engine has compared to long haul engines.
LEAP is sharing the A320neo platform with Pratt & Whitney’s GTF but is sole engine on the 737 MAX and the C919. This will lead to engine production rates five years into the program of 1800 engines which is higher than the present rate of CFM56 deliveries.
Dependant on rate increases by Airbus and Boeing, this can increase beyond 2,000 engines per year after the initial ramp. It would make LEAP the largest civil turbofan program whichever way one counts: engines, installed thrust or revenue.
Summary:
- Research of optimal engine cycle was extensive, with more than 1,000 alternatives investigated before settling on the final LEAP cycle.
- The production ramp is the fastest ever, from 30 engines 2015 to 1,700 by 2019.
- While CFM does not want to ramp faster than planned, final production rate is flexible.
- The large volume of sold engines, the fast production ramp and the short-haul cycle makes for a conservative approach to performance.
- We discuss with Richards how such a program is managed and how you make sure you can deliver on promises.

June 29, 2015, © Leeham Co. Cost control is going to be one of the top priorities of Dennis Muilenburg, the new chief executive officer of The Boeing Co.
Muilenburg, the president and chief operating officer for the past 18 months, was named last Tuesday CEO. Current chairman and CEO Jim McNerney relinquishes the latter title on July 1 but remains chairman.
We outlined many of the challenges Muilenburg faces as CEO in this post from January. Now that it’s official, an update is in order.
Summary
- Deferred production costs on the 787 continue to weigh down the company.
- Pricing pressure from the Airbus A330neo add to the 787’s woes.
- Production gaps for the 747-8, despite the announcement last week to lower rates from 15/yr to 12/yr in March next year, and the 777 Classic remain a major concern.
- The 737-9 MAX is failing to contribute its share to support profits and Free Cash Flow (FCF).
- Pressure to sell the 777 Classic is lowering prices, profits and cash flow on this line.
- Boeing’s commitment to huge stock buybacks for shareholders requires strategies to boost cash flow.
Embraer CEO talks about risks

Introduction

June 22, 2015, Paris Air Show, © Leeham Co. Embraer has emerged as the#3 commercial aircraft producer over the years, behind Airbus and Boeing and overtaking Bombardier, by approaching risks carefully and conservatively. No other decision in recent years reflects this approach than what to do when events outside its control forced officials to decide what to do about the future of the E-Jet.
Bombardier launched the CSeries with a new design and a new engine. The larger of two models, the CS300, was a direct challenge to Airbus and Boeing and their smallest aircraft. Airbus responded with the New Engine Option family, forcing Boeing to react with the re-engined 737, the MAX.
With the smallest CSeries, the CS100, a competitor to the largest EJets, the E190 and E195, Embarer had to do something. The question was what.
Embraer could launch an entirely new, larger aircraft, following the Bombardier example. It could do a “simple” re-engine of the EJet. Or it could do something else.
Officials chose to stay away from confronting Airbus and Boeing with a CS-300-sized EJet. Instead, they drew the line at 133 seats in highest density, adding 12 seats to the E-195. The Pratt & Whitney GTF was chosen to power a fundamentally new airplane, one with new wings, new systems, aerodynamic upgrades and other improvements.
We met with CEO Paulo Cesar de Souza e Silva at the Paris Air Show to talk about EMB’s approach to global risk factors.
Summary
- Oil prices, over-ordering and over-expansion by airlines factor into Embraer’s market assessments.
- Airline focus on market share rather than profitability is bad decision-making.
- Asia is Embraer’s best opportunities today.
A350 replacing A340-300 / 777-200ER, still on with lower fuel prices?

Introduction
June 7, 2015, c. Leeham Co. We have just rounded off a series of articles around how A350 is to fly, its systems approach and lastly the conversion of Finnair’s A340/A330 pilots to A350. Finnair will replace the airlines A340-300 with the A350-900.
A question that comes up is how much more efficient is the A350 that is delivered to these airlines, and does the investment still make sense with today’s lower fuel prices? To get an answer we took the two customers that will get their A350 within the next months, Vietnam Airlines and Finnair, and we compared A350-900 to the aircraft that it will replace in their fleets, Boeing 777-200ER for Vietnam Air and Airbus A340-300 for Finnair.
We used our proprietary model to fly these aircraft over some typical routes for the airline’s, for Vietnam Airlines Saigon-London and for Finnair Helsinki-Shanghai.
Summary:
- The present aircraft are over 20% less efficient than A350 on these routes.
- For the A340 it is the engines which are the culprit, for the 777-200ER the wing.
- With a realistic fuel price for the planning period the differences in efficiency are large enough to motivate the switch.
A changing Airbus
By Bjorn Fehrm

Introduction
June 3, 2015, c. Leeham Co. Airbus, the commercial aircraft part of Airbus group, is in a change period which in terms of its results will be as profound as the many restructuring programs “Power 8”, “Power 8 plus” and “Future EADS” were in unifying and restructuring Airbus after the A380 problems.
The change is taking place in a very different environment. Airbus and Airbus group are no longer plagued by national infighting and severe duplication of resources, the drivers for the previous programs. Rather it is a necessary change for a company that goes from focusing on getting large new aircraft developments out the door and expand market share, to a company which needs to focus productivity and how to avoid complacency.
Widebody sales prospects this year
Subscription required.
Introduction
June 3, 2015, c. Leeham Co. Sales of widebody jets have slowed going into the Paris Air Show in under two weeks. Airbus sold six A330-200s, four A330-200Fs and
Boeing hopes to make a sale to Emirates Airlines later this year for the 787-10, giving a boost to this program and acing out Airbus in the process.
25 A330-900s, or 35 widebodies. No A350s. No A380s. Boeing sold three 747-8s, one 767, 25 777 Classics and (net) 34 787s, or 63 widebodies.
But we expect sales to pick up for the second half of the year, propelled by what appears to be enticing hints by Airbus that it may have finally achieved sales from China for its long-stalled A330ceo Regional airliner.
But the big prize, the Emirates Airlines order for 50-100 Airbus A350s or Boeing 787-10s (the number varies), is likely a late-in-the-year deal. There are a couple of others of decent size being competed as well.
And then there is the prospect of the launch of the Airbus A380neo.
Summary
- Airbus looks to Air Show to boost orders
- Boeing continues to hope 777F will save the day on the Classic
- Deals by year-end hoped for.
- Next big opportunity: the Dubai Air Show.
