Oct. 27, 2020, © Leeham News: Boeing’s 737 MAX may be nearing recertification and airlines worry about passenger acceptance.
LNA pointed out the poor sales of the 7 MAX in the past. We’ve also compared the lagging sales of the 9 MAX and 10 MAX compared with the A321neo.
As a result of the MAX grounding and now COVID-19’s disastrous financial impact on airlines around the world, more than 1,000 orders have been canceled or reclassified as iffy under the ASC 606 accounting rule.
Airbus doesn’t publicly reclassify the European equivalent of ASC 606. But LNA in July estimated how many A320s would be similarly classified. At that time, about 425 appeared to be similarly subject to ASC 606 if this accounting rule was applied to Airbus.
Oct. 12, 2020, © Leeham News: Every year, like clockwork, when Boeing publishes its 20-year Current Market Outlook, there is always another upward revision in forecast demand for new aircraft.
So, when the Chicago-based OEM admits that demand has taken a long-term hit, you know the situation must be dire.
Last week, Boeing belatedly published its annual CMO forecast for global commercial jet production and services. The forecast was quite a comedown as it marked a 2% fall from Boeing’s previous expectations for aircraft demand, with a whopping 10% drop for widebodies and freighters.
Airbus has withheld its 2020 Global Market Forecast while it continues to assess the impact of COVID-19. Read more

Different from carbon fuels, liquid hydrogen needs specially shaped and bulky tanks. It can’t be stored in the wingbox as today’s Jet-A1.
August 21, 2020, ©. Leeham News: In our series on hydrogen as an energy store for airliners we start the design discussion of a hydrogen-fueled airliner by understanding the onboard storage of hydrogen better.
While there is present knowledge from for instance the space launcher industry, the storage demands for launchers are hours rather than days. Several implementations of longer storage aeronautical tanks have been done, among others by NASA/Boeing for high flying UAVs.
Airbus and the Russian aircraft industry were also active with research during the 1990s and Tupolev built a test aircraft that included a complete hydrogen fuel system (Figure 1).
Fifth in a series.

July 15, 2020, © Leeham News: UAC stands for United Aircraft Corporation, and is the name of the group owning the Russian aircraft industry.
After the fall of the Soviet Union, the multitude of individual companies and design bureaus could no longer survive on their own. The Russian state, therefore, gathered them all in UAC to introduce necessary consolidation and reform.
While UAC has done much with the support of the Ministries of Industry and Defense, the changing political situation for Russia has made it harder for the Civilian aircraft side to achieve sales outside captive Russian markets for its jets.
April 6, 2020, © Leeham News: It’s going to be quite a while before there is a clear understanding how coronavirus will change commercial aviation.
LNA already touched on impacts to Airbus, Boeing and Embraer. None of it is good. For Boeing, burdened with the additional stress of the 737 MAX, is in the worst position. Even when the MAX is recertified, there won’t be many—or any—customers in a position to take delivery of the airplane.
Bearing in mind that what’s true today will change in a day, or even an hour, let’s take a rundown of where things seem to stand now.

November 14, 2019, © Leeham News: The US mainline airlines have large fleets of 50-seater regional jets that are getting old. The present Scope Clause limits on the number of aircraft with seating over 50 seats stop the mainlines from replacing these aircraft with larger aircraft. So there is a real need for an efficient 50 seater regional aircraft for the US market.
As there are no 50 seater jets in production, United is converting its 70 seater CRJ700s to 50 seaters to fill the gap and calls them the CRJ550. This is where de Havilland Canada sees a change for an adapted DHC 8-400 turboprop. It’s more efficient than a CRJ550 while offering the same comfort, says de Havilland. We check if this is correct and what chances a DHC 8-“550” have in this market.

We shall look closer at the likely cause of the accident, which involves the SSJ100 Fly-By-Wire (FBW) control system working in Direct law.
April 26, 2019, ©. Leeham News: In the wake of the 737 MAX crashes the standards to which Boeing and the FAA qualified and approved the 737 MAX MCAS function is questioned.
FAA has called the world’s aviation regulators to a meeting on the 23rd of May to discuss how the revised MCAS function will be approved. But it’s time to discuss more than how the updated MCAS shall pass.
December 27, 2018, © Leeham News.: In July the CSeries changed from Bombardier to Airbus and in November the Q400 program was sold to Viking Air, the buyer of de Havilland Canada aircraft from Bombardier like the Twin Otter and the water bomber CL415.
When the Viking Air deal closes in the second half of 2019, only the CRJ regional jet will make up Bombardier Commercial Aircraft. Will the CRJ stay with Bombardier or go? And if so, why?
