Ryanair orders 737 MAX, giving boost to Boeing
By Scott Hamilton
Dec. 3, 2020, © Leeham News: Ryanair today announced an order for 75 Boeing 737-8 200 MAXes.
This is the first big order for the airplane since the March 10-13, 2019, grounding. It’s the first since the US Federal Aviation Administration and Brazil’s ANAC lifted their grounding orders last month.
Europe’s EASA plans to lift its grounding order in January. Ryanair, of Ireland, can’t fly the MAX until EASA acts.
The deal is a boost for Boeing and a vote of confidence in the MAX. The global fleet was grounded following the second of two fatal accidents.
Restoring operations of the 737 MAX
By Bjorn Fehrm
December 1, 2020, ©. Leeham News: Boeing and its customer airlines have 837 MAX airliners that shall get back in the air. After the FAA and ANAC, Brazil’s regulator, have stated the conditions, the work can begin. EASA and Transport Canada will follow with eventual modifications on what needs to be done.
There can be no slip-ups when the 737 MAX flies again. Boeing and the airlines know this; hence there is no room for hurried work or compromises. It will take two years to get the job done, according to Boeing.

HOTR: Boeing hopes for break in China order drought after electors vote for Biden:
By the Leeham News Team
Nov. 30, 2020, © Leeham News: Boeing hopes the three-year order drought from China may come to an end next month.
The order, according to market intelligence, would be a boost for the slow-selling 777X. It could also mean new orders for the 787. Orders for the latter dropped significantly enough to prompt Boeing’s decision to shutter the Everett 787 production line next year. Production for the 787 will be consolidated in Charleston (SC).
Dec. 14 is when US presidential electors meet to cast their votes for Joe Biden or President Donald Trump, making official the projected winner. Biden won 306 electoral votes to Trump’s 232 in projections by all the major media. With almost all votes counted—and in some cases, recounted—Biden has 51.1% of the vote to Trump’s 47.2%. Biden received 80.1m votes to Trump’s 73.9m. The margin was nearly 6.2m.
China hasn’t ordered a Boeing airplane since 2017. Trump launched a trade war with China that escalated several times. He charged, without evidence, that China interfered with the US presidential election.
Boeing hopes for a major order from China as early as December. Included would be a sorely needed order for the 777X. (Shown: Boeing 777-300ER.) Photo source: Boeing.
Bjorn’s Corner: 737 MAX ungrounding, ANAC’s and EASA’s decisions
By Bjorn Fehrm
November 27, 2020, ©. Leeham News: After the lifting on the grounding order by the FAA, ANAC (Brazils regulator) followed in the week, and EASA issued its plans for public comment.
What are the differences in the ungrounding conditions, and what are the reasons for any differences?

Boeing 737 MAX changes beyond MCAS
By Bjorn Fehrm
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.
Pontifications: Why I’d fly the MAX; lessons learned and still to come
Nov. 23, 2020, © Leeham News: I’m okay with flying on board the Boeing 737 MAX.
Yes, it’s gone through the wringer in the 20 months since it was grounded.
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.

Bjorn’s Corner: 737 MAX ungrounding, the technical background
By Bjorn Fehrm
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.

FAA recertifies Boeing 737 MAX
- Continuing coverage in next post
By Bjorn Fehrm
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?
Below we go through what went wrong and why this chain of events will not happen again on an updated 737 MAX.
