Introduction
August 19, 2021, © Leeham News: In our series about freighters, we now look at domestic freighters based on the Boeing 757-200 and the Airbus A321. The 757-200 is a popular Passenger to Freighter (P2F) conversion, but as production of the 757 stopped in 2004, there is a limit to the conversion feed-stock for the model.
At the same time, older A321s are reaching market values where their cost enables competitive P2F conversions.
We use our performance model to check if the A321P2F is a good alternative to the 757-200P2F.

Summary
- The feed-stock for the Boeing 757-200 Passenger to Freighter conversions will diminish at some point in the future.
- The alternative in the same freight volume class is a converted A321. We check how well it fits the bill as an alternative to the 757-200.
De-carbonisation of air transport is ON
By Bjorn Fehrm
July 20, 2021, © Leeham News: Last week was a game-changing week for air transport. Three events synchronized to trigger it.
EU presented 13 policies to achieve net-zero greenhouse gas emissions by 2050 with concrete steps in-between. On the same day, the airframe and engine OEM’s CTOs said in a Farnborough Connect webcast: “It’s a commitment problem, not a technical problem to achieve the EU goals.”
This happened against a backdrop of European floodings, which made all discussions about climate change or not moot. Super-organized Germany lost over 100 persons to typhoon like rains, never seen before, that produced scenes like these: https://twitter.com/Aviation_Intel/status/1416215953080205321?s=20

Introduction
December 10, 2020, © Leeham News: Last week, we introduced the Boeing 717 and its closest replacement size-wise, the Airbus A220-100. Delta, a major 717 customer, is accelerating the replacement of the 717 with the A220-100 under the pressure of the COVID19 pandemic.
We use our performance model to understand why. What are the gains when going from the 717 to an A220-100?

Summary
- The 717 version of the DC-9 architecture produced a rugged and well-liked short-haul airliner. It’s five abreast cabin is preferred over the six-abreast Boeing 737 and Airbus A320.
- It’s size-wise in the same 115 seat bracket as the 15 years younger Airbus A220-100. It’s 40 years old airframe architecture holds up well compared to the modern A220.
- The engines of the two are also 15 years apart. But the Rolls-Royce BR715 of the 717 was originally designed to fly on fast business jets, necessitating a low by-pass ratio design. This is a handicap when used on lower speed airliners. It shows against the high bypass ratio Pratt & Whitney PW1500G of the A220.
The engine manufacturers worst hit by the pandemic

Introduction
September 28, 2020, © Leeham News: The worldwide COVID-19 pandemic is shaking the air travel and airliner manufacturing industries like no crisis before.
More than 9/11, the oil crisis of 1973 or 2005 or the financial crisis of 2008. The problems for the airlines and the airframe OEMs are on the front pages of the world’s media.
The part of the airliner industry that is not so visible but is perhaps hardest hit, is the engine industry. Its weird business model amplifies the effects of the crisis.
Summary
- Airframe OEMs lose money on the first hundreds of aircraft produced.
- When they announce “black numbers”, it means the per aircraft losses stop. It doesn’t mean the aircraft program is positive.
- For engine OEMs, it’s worse. They never reach ‘black numbers” on engine production. Their only money makers are old engine programs that fly a lot.
A lost decade for aircraft manufacturers, suppliers

Introduction

Sept. 21, 2020, © Leeham News: Commercial aviation is facing a lost decade due to COVID.
Yes, most forecasts target 2024-2025 as returning to 2019 passenger traffic and aircraft production levels.
However, LNA in July published its own analysis indicating full recovery may not occur until 2028. Breathless headlines notwithstanding, it will take years for vaccines to be widely available and considered safe by enough of the world’s population. Growing concern about vaccine production and distribution capacity through 2024 underscores this view. Even Southwest Airlines CEO Gary Kelly said earlier this month that business travel might not fully return for a decade.
Indeed, the 2020s may well be a lost decade for aircraft manufacturers and their supply chains.
Summary
- Debt-laden airlines will have little money to order new airplanes
- Interest in re-engined 787, A350 likely nil this decade
- Airbus, Boeing, Embraer have little interest in launching new programs
- Engine makers too financially stretched to develop new designs
- Engineering talent, knowledge will be decimated by inevitable job reductions
- OEMs must “play the long game” at a short-term cost to safeguard their futures

Introduction
August 12, 2020, © Leeham News: We deepen our look at the Queen of the Skies and it’s best selling version, the 747-400.
We go through what made it the great aircraft it was and why Qantas replaced it on its trunk routes to the US West coast.
We pick Los Angeles to Sydney as the benchmark route, a route on the range limit for the 747-400, and check how it stacks up economically versus the A380, its replacement.
Summary
- The 747-400 reigned the skies for 15 years, combining a trans-Pacific range with a good passenger and cargo capacity.
- Once Boeing introduced the 777-300ER and Airbus the A380, the 747-400’s ruling of the skies was over. It trailed in both capacity and efficiency.
- It continued in operation until today with many airlines, still a useful aircraft for long and dense routes as long as the fuel prices stayed low.
Embraer’s Slattery named CEO of GE Aviation
By Scott Hamilton
June 15, 2020, © Leeham News: John Slattery, the CEO of Embraer Commercial Aviation, was named CEO of GE Aviation, it was announced today.
John Slattery
Arjan Meijer is the new President and CEO succeeding Slattery. Slattery succeeds David Joyce, who is retiring. Slattery’s appointment is effective July 13.
Slattery devoted much of the last year trying to win approval of the proposed Boeing-Embraer joint venture, Boeing Brasil-Commercial. Boeing terminated the agreement April 25, claiming Embraer failed to meet all required terms and conditions. Embraer claims it met the conditions. Both took the dispute to arbitration.
Slattery had been designated CEO of Boeing Brasil. After the deal’s collapse, his departure from Embraer was expected.
Pontifications: bleak near- to mid-term future for Rolls-Royce engine unit
By Scott Hamilton
June 15, 2020, © Leeham News: The jet engine division of Rolls-Royce faces an uncertain future because of its own problems, exacerbated by the impact of COVID-19 on commercial airlines.
Beset by problems with its Trent 1000, Boeing 787 engine, hampered by a huge error in judgment to withdraw from a joint venture with Pratt & Whitney, beset by the premature termination of the Airbus A380 program and now facing a long-term impact of the coronavirus crisis, Rolls is an engine maker with few opportunities.
Pontifications: Pratt & Whitney uses COVID crisis to catch up on GTF fixes
By Scott Hamilton
June 8, 2020, © Leeham News: Pratt & Whitney struggled since its new Geared Turbo Fan engine entered service in 2016 to fix technical, reliability and operational issues.
Plagued by premature engine removals as parts, other than the gear box, failed, Airbus A320neos stacked up in Toulouse and Hamburg while new engines were diverted to operators with aircraft out of service.
India’s regulator issued a grounding order of GTF-powered neos. Shop visits for repairs and modifications overwhelmed PW. The mess cost PW parent United Technologies (now Raytheon Technologies, following a merger) billions of dollars.
Working its way out of this mess was forecast to take into 2021.
Now, with COVID-19 impacts grounding airliners by the thousands, PW is using this as an opportunity to speed replacement and reworked engine deliveries.

Performance Improvement Packages (PIPs) will be ready this summer.
“If there is any silver lining in the environment we’re in today, it is likely around the GTF and the retrofit,” Raytheon CFO Toby O’Brien said during a UBS webcast last week. “We are utilizing available shop capacity to fix the issues in the fleet. Our goal is to have GTF engines with enhancements by the end of the year as the recovery plays out.”
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.
