November 24, 2020, ©. Leeham News: Last week, we went through the core MCAS changes the FAA demanded from Boeing to lift the grounding of the 737 MAX 8 and 9. As the investigation into the MAX crashes deepened, changes were added beyond the core MCAS related changes.
A single sensor failure, like the Angle of Attack failures for Lion Air JT610 and Ethiopian Airlines ET302, triggered a multitude of failure warnings. These warnings absorbed the crew’s concentration, invalidating FAA certification assumptions on crew reaction times for critical trim failures. As a result, the FAA required additional crew alert and procedure changes for the MAX.
Nov. 23, 2020, © Leeham News: I’m okay with flying on board the Boeing 737 MAX.
Yes, Boeing and the US Federal Aviation Administration screwed up royally.
And yes, there’s solid reason to distrust the company and the agency, wondering if they got it right this time.
Which is why for me the tipping point is the involvement of Transport Canada and Europe’s EASA are the reasons to trust getting back on the MAX.
LNA addresses the safety in our new podcast feature, 10 Minutes About. The inaugural podcast, 10 Minutes About the Boeing 737 MAX recertification may be heard here.
November 20, 2020, ©. Leeham News: This week’s big news is the lifting of the grounding of Boeing’s 737 MAX.
I wrote about the changes made to the MAX Wednesday and why I believe it’s safe. Let’s use our Corner space to walk through what I wrote about, but with a more technical angle.
Nov. 18, 2020, (c) Leeham News: The US Federal Aviation Administration today recertified the Boeing 737 MAX, ending a 20-month grounding.
Recertification of the airplane will follow by Transport Canada and Europe’s EASA, probably this month.

November 18, 2020, ©. Leeham News: The FAA has declared the Boeing 737 MAX 8 and 9 safe to fly after a 20 months grounding. On March 10, 2019, the Ethiopian Air ET302 crashed after Boeing’s pitch augmentation software MCAS triggered erroneously and caused the aircraft to crash. This accident followed a similar accident of Lion Air JT610 on October 29, 2018.
Ethiopia grounded the MAX on the day, China the day after, and the FAA on March 13. The 737 MAX has been grounded worldwide since the FAA grounding.
It has been a gruesome 20 months for Boeing, where it’s gone from denial of guilt to a full acceptance of responsibility and a complete change of attitude. With changes to the MAX verified by FAA, EASA, Transport Canada, and Brazil’s ANAC, it’s now ready to fly again.
We will cover the return to flight of the 737 MAX in several articles, the first dealing with the question: Is the 737 MAX safe to fly?
Called “10 Minutes About,” the podcast is—as the title says—10 minutes about the issue selected. This time frame is short, to the point and doesn’t take too much time from the listener.
Today’s launch podcast is 10 Minutes About the 737 MAX Return to Service. The US Federal Aviation Administration today recertified the MAX.
Nov. 16, 2020, © Leeham News: The European Union implemented tariffs Nov. 9 on Boeing and other US products in retaliation for the Trump Administration tariffs on Airbus and EU products.
This is the latest in the 16-year trade battle between the US and Europe over subsidies and tax breaks found to be illegal under World Trade Organization rules.
The US was authorized last year to impose tariffs on Airbus and other EU products. The Trump Administration initially imposed a 10% tariff on imported Airbus aircraft. A320/321s assembled at Airbus’ Mobile (AL) plant were exempt, even though major components were imported.
Trump increased the tariffs to 15% in March, just as the COVID-19 pandemic erupted worldwide. As a result, few Airbus airplanes were delivered into the US since then.

Nov. 10, 2020, © Leeham News: Pfizer yesterday announced it’s on track to produce a COVID-19 vaccine that appears to be 90% effective in trials. The company is one of the world’s leading drug makers.
This is good news.
“Read the fine print at the end of the press release,” Rollins says.
“Based on current projections, we expect to produce globally up to 50m vaccine doses in 2020 and up to 1.3b doses in 2021,” the press release says.
“It’s a two-dose vaccine, so divide by two to figure the number of people who could be immunized,” Rollins says. “Even if a second candidate is approved and can be produced in the same quantity next year, that means just 17% of the world’s population will be vaccinated. And that assumes everything goes according to plan.”
Rollins did an extensive analysis of how quickly global air traffic would return to normal. In his July 13 post, Rollins projected that traffic won’t fully recover until 2024 at the earliest or 2028 at the latest. It all depends on how quickly a vaccine was developed, how quickly it could be distributed globally and how quickly people had confidence in it.
“We’re in only the second or maybe third inning of a very long ball game,” Rollins says. “Vaccines kill off a virus by denying it bodies in which to reproduce. If you don’t innoculate enough of the population while immunity lasts, you’re back to square one.”

Nov. 9, 2020, © Leeham News: Boeing needs hundreds of new orders for the 737 MAX and/or a new replacement program launch by 2026, if not sooner.
An analysis shows that 737 deliveries tank by 2028.
This isn’t just about the 737-10 and 737-9, which don’t fare well against the Airbus A321neo. The shrinking backlog is the problem.
Ryanair’s CEO, Michael O’Leary, said last week Boeing will delay delivery/entry into service of the 737-10 MAX by up to two years.
This largely stated the obvious.
The first 10 MAX rolled out of the factory Nov. 22 last year. It could not enter flight testing because the MAX family was grounded March 13. The MAX remains grounded. Recertification may come this month, but it appears more likely next month.
This delays the start of flight testing until probably January. This is a 14-month delay.
Flight testing will take a year to 15 months, or to January to March 2022—about two years after the planned EIS. Boeing’s production ramp up will further impact delivery of the 10 MAX.
Although some recent new focus was on the 10 MAX, the larger issue is the entire 737 family.
