Engine OEMs forecast big hit to aftermarket revenue

May 5, 2020, © Leeham News: The COVID crisis will damage the aerospace aftermarket in ways that are only beginning to be understood.
As key companies report 1Q earnings, it’s clear that engine aftermarket revenue is going to take a major hit for years to come.
Engine companies like CFM, GE Aviation, Pratt & Whitney and Rolls-Royce, rely on aftermarket sales as the key component of their business plans.
The research and development money that goes into an engine consumes such huge amounts of cash that the OEMs don’t recoup their costs for 10-20 years. The aftermarket for parts, maintenance, repair and overhaul is where they make their profits in the meantime.
But this is seriously threatened by the virus crisis.
“The aftermarket for key programs took 4+ years to return to 2008 levels out of the Great Financial Crisis, and that was with traffic decline at a fraction of the declines today,” Bernstein Research wrote in a May 4 note to clients.

April 2, 2020, © Leeham News: Boeing’s New Midmarket Airplane, or a new concept, is the last thing on the plate right now.
But Boeing’s future product strategy nevertheless requires long-term thinking even as the short- to medium-term is in chaos.
Interviews were conducted March 2 at a major aerospace conference in Austin (TX), just days before the coronavirus crisis exploded exponentially across the globe.
The CEO of the major lessor, Avolon, declared the NMA dead and predicted a new single-aisle airplane will be Boeing’s next project.
An executive of Pratt & Whitney offered a similar view.
Summary
- “The NMA is gone. Long live the NMA. That moment has passed.
- Back to the 757 replacement concept and, now, A321XLR competitor.
- Single-aisle vs light twin-aisle is part of the challenge.
- New airplane must be “dramatically” more efficient than MAX, neo.
- 2030 decade is the quickest this dramatic improvement can be achieved.
Pratt & Whitney committed to advanced GTF for Airbus

March 30, 2020, © Leeham News: Pratt & Whitney is concurrently developing what might be termed the next generation GTF. This is an advancement over the current engine, but with more thrust and better fuel economics.
Deurloo eschews the usual Performance Improvement Package (PIP) moniker, however.
“We have been discussing with Airbus for some time, an improvement to the current configuration or our expected configuration,” Deurloo said. “I think that’s a testament to the geared architecture. It’s given us some runway to do a little bit more on that engine.
PW has been in conversation with Airbus for the last few years about an engine that will take configuration at the end of this year, and put in an improvement.
Summary
- New name, better economics, better durability.
- Designed for the A321XLR, but greater flexibility.
- Fixing current issues.
Bjorn’s Corner: Why e in ePlane shall stand for environment, Part 3. Open rotor revisited.
January 3, 2020, ©. Leeham News: We continue our series why e in ePlane shall stand for environment and not electric.
Our target is to lower air transport’s environmental footprint and we can achieve this more efficiently by using established technologies. As an example, I will describe a very promising concept that has fallen out of focus due to the hype around everything hybrid and electric.

Understanding Rolls-Royce’s financials

Introduction
Dec. 2, 2019, © Leeham News: Rolls-Royce continues to be in the spotlight for the Trent 1000 durability issues, with no end in sight. The engine manufacturer recently increased the total disruption cost estimate to £2.4bn.
The engine-related charges and substantial research and development expenditures have raised questions about Rolls-Royce’s fin
ancial health. As of the end of 2018, the company had a net negative £1bn equity on its balance sheet.
However, the company has a market capitalization of around £14bn and holds a credit rating comfortably in Investment Grade territory.
This article analyzes the reasons for the disconnect between the company book value and market capitalization. Accounting differences between the USA’s GAAP and Europe’s IFRS play a significant role.
Rolls-Royce’s strategic choices in the early 2010s will have ramifications for engine development on future commercial aircraft programs.
Summary
- A tumultuous history;
- From cash cow to binge development spending;
- Brexit and IFRS accounting paint bleaker pictures than reality;
- Strategic decision bites back;
- A lifeline and future engine programs.

Summary
- Pratt & Whitney geared turbofan (GTF) operational limitations on A220, A320neo.
- CFM LEAP said to be causing renewed A320neo delivery delays.
- Multiple new airworthiness directives on Trent 1000, 7000.
- GE9x component issues causing delays to first 777X test flight.
Is re-engining the Boeing 767 a good idea?
By Bjorn Fehrm

Introduction
October 17, 2019, © Leeham News: FlightGlobal writes Boeing is investigating re-engining the 767-400ER with GE GEnx engines to produce a new freighter and perhaps a passenger aircraft as a replacement for the NMA project. Development costs would be lower and it would be easier to get a business plan which closes for the upgraded 767 than for the NMA.
We commented on the idea earlier in the week and here follows a technical analysis of what re-engining the 767 would bring.
Summary:
- The 767 is 40 years old in its base design. We look at the fundamentals to understand the trades involved in extending its life with new engines.
- We also compare the 767 technologies with those for the NMA to understand the compromises of an updated 767RE compared with a clean sheet NMA.

Introduction
October 10, 2019, ©. Leeham News: We have over the last weeks analyzed what aircraft to choose for the segment 120 to 150 seats, comparing Embraer’s E195-E2 with Airbus A220-300.
After looking at fundamental data, drag data and fuel consumption and other costs for the aircraft, it’s now time to summarize the series by looking at what route networks the aircraft are suitable for.
Summary:
- The E195-E2 and A220-300 address the segment market segment under 150 seats.
- They have similarities but also differences.
- These differences have made an early adopter operate both types over different types of networks.

Introduction
October 3, 2019, ©. Leeham News: We have the last two weeks analyzed what aircraft to choose for the segment 120 to 150 seats, comparing Embraer’s E195-E2 with Airbus’ A220-300.
The first week we looked at fundamental data and last week we compared the drag data and by it the fuel consumption of the aircraft. Now, we analyze the other operational costs for the aircraft.
Summary:
- The fuel costs between the E195-E2 and A220-300 are close.
- We now analyze the other operational costs; Crew, Maintenance and Airway/Airport costs to see how these differ.
A380 service life struggles

Introduction
Sep. 30, 2019, © Leeham News: It hasn’t been an easy year for the Airbus A380 program since the end of production was announced in February.
Lufthansa announced in March that Airbus would buy back six A380s in 2022/2023 as part of a follow up order for 20 A350-900s. Air France intends to retire its Superjumbo fleet by 2022. Emirates retired two aircraft that were less than seven years old.
A number of factors are leading airlines to prematurely retire their A380s.
Summary
- Small MRO market increases maintenance costs;
- (Prohibitively) expensive cabin refurbishments;
- Operators struggling to operate profitably year-round;
- A lack of secondary market;
- No business case for engine PIPs.
