April 4, 2022, © Leeham News: Returning the 737 MAX production rate to pre-grounding levels, and beyond, is a key element to positioning Boeing to launch a new airplane program.
So far, Boeing hasn’t provided any guidance to Wall Street aerospace analysts beyond reaching a rate of 31/month this year.
A month ago, LNA reported that hints of new rates came from Boeing suppliers ATI and Spirit Aerosystems during their investor day presentations. The two days were a week apart. ATI is a parts supplier. Spirit builds entire fuselages for the 737. The investor days suggested that Boeing will return to rate 52, the pre-ground MAX rate, by 2024.
LNA has learned more specific information from its sourcing in the supply chain. Boeing notifies the chain when to expect rate breaks to higher or lower rates for planning purposes.
According to LNA’s latest information, Boeing is planning to achieve a rate of 38 by January 2023 and boost it to a rate of 47 by the summer of 2023. Another rate break would boost production to 52 a month early in 1Q24. When regulators grounded the MAX in March 2019, Boeing was geared up to boost production to 57 a month by year-end.
So far, Boeing apparently hasn’t given guidance to its supply chain beyond rate 52. But if the pattern holds up, rate 57 could be in the cards by the end of 2024. Orders for the MAX, especially for the MAX 10, have picked up nicely.

April 1, 2022, ©. Leeham News: Last week, we looked at how to store hydrogen in an aircraft. We could see the gaseous storage of hydrogen is too heavy other than for demo systems and extreme short-haul. For practical airliners, liquid hydrogen is the solution.
Now we look at what this means for the aircraft fuel system and how to configure a suitable Auxiliary Power Unit, APU.

March. 31, 2021, © Leeham News: Last week’s article showed that a Boeing 787 freighter based on the -9 variant would be a suitable replacement for the aging 767-300F.
Should Boeing proceed with the aircraft, expect Airbus to launch a competing airplane, it not launch it before the American OEM.
The A330-200F recorded 38 sales as a factory freighter, a disappointing tally. Which aircraft variant could Airbus use as a baseline to develop a more successful 787F competitor?

March 28, 2022, © Leeham News: In an article last year, LNA highlighted the significant impact the COVID-19 pandemic had on the financials of commercial aviation OEMs. Most recorded sizable losses and charges.
The OEMs entered into a recovery mode in 2021. Airbus intends to aggressively increase its A320neo family production rates to satisfy a strong demand, while Boeing must clear large 737 MAX and 787 backlogs.
The impact of changing production rates takes time to ripple through the supply chain. LNA collected financial information on the big three aircraft manufacturers and seven major commercial aircraft suppliers to assess how quickly they are recovering from the most significant shock since World War II.

March 29, 2022, © Leeham News: Alaska Air Group announced last week that its subsidiary, Horizon Air, will retire 32 De Havilland Canada (DHC) Dash-8-400s by the end of 2023. The regional airline will go to a single fleet type, the Embraer E175-E1. AAG owns some of the 175s. Regional partner SkyWest owns and operates others.
The plan adds to the struggles of DHC to return to service -400s stored at the start of the COVID pandemic. At the end of 2021, there were more than 150 stored. As of last week, this number was down to 142, according to the ch-aviation data base. Another 17 were in maintenance. There were 398 in service. The number stored represents 25% of the -400 fleet.
Consolidating to a single fleet type doesn’t bode well for Embraer’s efforts to win Alaska/Horizon as a launch customer for its new TPNG. This advanced turboprop, proposed in 70- and 90-seat versions, has engines mounted on pods at the rear in the latest concept shown to the industry. A new engine will replace the aging but reliable Pratt & Whitney PW-series used on the Dash 8 and ATR-42/72. P&W, GE and Rolls-Royce are developing a new generation engine.
Embraer wants to launch the program this year with a proposed entry into service of 2027.

March 24, 2022, © Leeham News: Last week, we discussed the creation of a Boeing 787 freighter. It shall replace the Boeing 767-300F, which is running into emission rule problems in 2027.
After looking at what 787 variant makes for the best freighter, we now compare the economics of the 787, 767-300F, and A330-200F freighters.

March 21, 2022, © Leeham News: A China Eastern Airlines Boeing 737-800 (Flight number MYU5735) crashed today while enroute to Guangzhou. All 132 people on board were killed.
For those likely to jump the gun, it is important to note that this 737 was a Next Generation model, not the MAX. The accident airplane was delivered new to the airline in 2015.

A screenshot of a Chinese CCTV video believed to show China Eastern MU5735 moments before crashing near Guangzhou.
According to flight tracking radar images, the flight was at cruising altitude when it nosed over into a vertical dive. A photo circulating on Twitter shows the airplane in a vertical position moments before the crash.
No conclusions may be drawn about the cause of the crash based on the sketchy information available. As a matter of routine investigative procedures, the following will be areas of inquiry, in no particular order:

March 21, 2022, © Leeham News: Lockheed Martin Co. (LMCO) plans to submit a proposal for the US Air Force’s KC-Y aerial refueling tanker procurement. So does Boeing. LMCO joined with Airbus and will offer a tanker based on the existing Airbus A330 MRTT (Multi-Role Tanker Transport). Boeing will offer a follow-on purchase of the incumbent KC-46A, based on the 767-200ER.
These two aircraft faced off in the KC-X competition. Airbus initially teamed with Northrop Grumman and was awarded the contract. Boeing protested the award on procurement procedural grounds and prevailed. Northrop dropped out of the recompete, which Boeing won in 2011.
The two aircraft will be offered again, but this time, one party doesn’t view the aircraft as competitive. LMCO sees the Airbus airplane, which it brands the LMXT, as complementary to rather than competitive to the KC-46A. Lockheed explains why here.
Boeing, on the other hand, isn’t convinced the USAF will even seek a competitive bid—or that LMCO’s belief that the service wants a larger airplane than the KC-46A to fill a “gap” is correct.
Mike Hafer, senior manager of KC-46A Business Development, explains why.

March 21, 2022, © Leeham News: Eyes are focused on Ukraine and the Russian War. In our corner of the world, commercial aviation, the stakeholders follow the fallout from the war: sanctions placed on Russia which affect overflights, supply chains, oil to Europe (fuel), and Russia’s confiscation of about $10bn worth of airliners from Western lessors and lenders.
But there is another drama playing out on the other side of the world, too. This one involves China and one of its commercial aviation companies, AVIC.
AVIC is a major aerospace company in China. It also has a variety of none-aerospace companies. It’s one of these that caught our eye last week.
The Wall Street Journal on March 14 reported that AVIC subsidiaries involved in solar energy filed for bankruptcy to avoid an $85m judgment after allegedly absconding with intellectual property from two US companies. The firm had to settle for 30 cents on the dollar.
It’s another example of China companies simply ignoring international IP laws.
