September 8, 2022, © Leeham News: Last week, we analyzed the change from turbojets to turbofans for civil air transport. The jet engine was developed for high-speed military fighters and was not ideal for subsonic airliner use.
We also dwelled on why the three major engine OEMs came to different solutions for the first-generation turbofans. Now we look at the engine that made turbofans mainstream, the Pratt & Whitney JT8.
July 4, 2022, © Leeham News: Any hope that the Delta Air Lines ALPA pilots union will agree to a slightly relaxed Scope Clause in its next contract are just wishful thinking.
Few thought DALPA, as the chapter at the airline is known, would up the weight of airplanes allowed under Scope. This is needed to permit regional airline partners to operate the Embraer E175-E2. The E2 is more environmentally friendly and economical than the E175-E1, a 1990s design with engines (the CF34) that date to 1982 when it first ran on the test stand. The CF34’s design is based on the military TF34 developed in the 1960s.
EMB’s E175-E2 was supposed to enter service in 2021. It’s been rescheduled three times. The current EIS is now targeted for 2027. Few believe Scope will be relaxed by then. There is a growing belief that the E175-E2 is dead. (Embraer says no.) DALPA is often an industry-leading union. Its refusal to relax the weight limit all but assures the E175-E2 is dead.

July 6, 2021, © Leeham News: Mitsubishi is considering restarting production of the discontinued CRJ, LNA confirmed with multiple sources.
Mitsubishi Heavy Industries discontinued production with the completion of the last of the small backlog it acquired with the June 1, 2019, purchase of the program from the ailing Bombardier. The final 15 CRJ900s were completed during the early months of the COVID-19 pandemic. The Montreal Mirabel Airport production line was shut down. The tooling was removed and stored. The buildings were turned over to Airbus, which now uses them for A220 production.
“Our primary focus remains the support of the CRJ operating fleet,” said Ross Mitchell, vice president of Shared Services. “Clearly, the regional jet market is important to us, but we have made no commitment to move forward in this respect.”

February 11, 2021, © Leeham News: Last week, we started analyzing the main member of the Airbus A350 family, the A350-900. It’s the design center for the A350 family and has so far 747 orders, of which 354 are delivered.
Over 1,000 Boeing 777 airliners in the market need replacement, and the A350-900 targets about half of these, the 777-200 and -200ER. Delta is one airline that started the switch from 777-200ER to A350-900. How much does Delta stand to gain?
Dec. 21, 2020, © Leeham News: This is my last Pontification of 2020. I’ll be off between the Christmas and New Year’s holidays.
It’s only fitting to look back at what is the worst year in commercial aviation—ever.
I’ve just completed my 41st year in this industry. I’ve seen two Gulf Wars, SARS, 9/11, the Great Recession and several economic cycles.
Lockheed and McDonnell Douglas exited the commercial airliner business.
I’ve seen three groundings: the McDonnell Douglas DC-10, Boeing 787 and 737 MAX. I’ve been on site of two significant crashes: the American Airlines DC-10 in Chicago and Delta Air Lines’ 727 in Dallas. I flew over a third, a Delta L-1011 in Dallas the day after it happened.
I worked for the first new airline certified by the Civil Aeronautics Board in 40 years, the first Midway. I also went through one bankruptcy and one merger, each part of the deregulation shake-out.
As a reporter, I covered some of the business giants, including Bob Crandall, Herb Kelleher, John Leahy and others.
It’s been a great four decades.
But nothing compares to the global industry disaster of 2020.
Second in a Series on the Future of Regionals
By Kathryn B. Creedy
Aug. 6, 2020, (c) Leeham News: Many might assume the recent loss of three regionals – Compass, Trans States and ExpressJet – is Covid related.
What is actually happening is the long-anticipated consolidation of the regional airline industry coupled with fleet restructuring and the most recent fallout of the pilot shortage crisis that began in 2013.
Reducing the number of regional partners also streamlines the inherent inefficiencies of the regional/major model.

July 9, 2020, © Leeham News: Last week, we started the analysis of restoring capacity with the Airbus A330-300 or the A330-900 when reopening international traffic after the COVID-19 lockdown.
As we did with the A330-200 versus the A330-800, we fly them side by side between Paris Charles de Gaulle and Sao Polo’s Guarulhos airports. It’s a 13-hour flight with maximum freight in the cargo bays to gain revenue in addition to our part full cabin.
Will the payload-range of the A330-300 or A330-900 be sufficient to load the aircraft for maximum revenue on the route? We use our airliner performance model to find out.

May 28, 2020, © Leeham News: As flying recommences after country lockdowns, the fill factors for the flights will be low for an extended period.
Airlines and the OEMs are anticipating the low load factors. For instance, Delta has not deferred any Airbus A220 deliveries but is postponing deliveries of larger aircraft. How much of an advantage is a smaller aircraft when opening up the traffic again?
We compare the operational costs of the Airbus alternatives. The cost of flying the A220-300 is compared with the A320neo.
May 18, 2020, © Leeham News: There simply is no good news in commercial aviation right now.
Yes, airport traffic is upticking in the USA (and elsewhere) slightly. But in the USA, it’s still less than 10% of last year’s totals.
There remains a tremendous amount of uncertainty.
The list goes on and on and on.

April 6, 2020, © Leeham News: With the COVID-19 pandemic, the passenger traffic has ground to a halt in many countries. The airliners are parked and their crews sit idle.
At the same time, the air freight market booms. From a decline in demand in the first months of the year, there isn’t enough freighter capacity right now. The freight that traveled in the bellies of the passenger jets had to find new ways and as this was almost half the world’s air cargo, the dedicated freighters can’t absorb the volumes.
Is it time to fly passenger airliners as substitute freighters? Some airlines are doing this on a spot basis. Apart from injecting capacity for needed medical supply freight, does it make economic sense? We run a series of articles on the subject.
