July 29, 2019, © Leeham News: The 737 MAX crisis overshadows everything else right now at Boeing.
This includes forward orders, weak customers and production gaps on the 787 line, which right now is the cash flow cow at Boeing Commercial Airplanes.
Boeing’s production line for the 787 is filled through 2021, but after that, there are big gaps. Source: Leeham Co. Click on image for a crisp view.
Executives only briefly, and obliquely, touched on the 787 during the 2Q2019 earnings call last Wednesday.
This prompted LNA to examine the details of the backlog and production rates. The 787 is current being produced at a rate of 14/mo.
There are clear signs of challenges, both near- and medium-term for the 787.
July 25, 2019, ©. Leeham News: Last week’s Corner which dealt with Airbus’ issue with an updated A321neo Fly By Wire (FBW) and how it was unrelated to the issue of the Boeing 737 MAX, gives a good segue to a Corner series about the possibilities of FBW versus classical flight controls when it comes to tuning an airliner’s flight characteristics.
The two different control principles present the designer with very different challenges and possibilities.

July 25, 2019, © Leeham News: We continue our discussion from last week of what part of an NMA market the Airbus A321XLR would capture.
We started the study by comparing the aircraft with a common yardstick. It brought some revealing insights. Now we continue by looking at the airline routes these aircraft can cover and their economics when covering these routes.

July 22, 2019, © Leeham News: Development of single-aisle aircraft that now have ranges of plus-or-minus 4,000 nautical miles are fragmenting hub markets needed to fill large twin-aisle aircraft.
Just as twin-engine widebodies began fragmenting routes needed to fill the Boeing 747 and later the Airbus A380, the Boeing 737-8 and Airbus A321LR/XLR appear to be contributing to weak demand for the Boeing 777X and Airbus A350-1000.
With launch of the Airbus A321XLR last month and expected New Midsize Airplane once the MAX crisis is over, some markets might have structures dramatically altered in the second half of next decade. The prime candidate is the US East Coast–Europe market. We will investigate through historical examples how things might turn out.
July 19, 2019, ©. Leeham News: The European Aviation Safety Agency EASA has issued an Air Worthiness Directive (AD) to instruct operators of the Airbus A321neo of a Pitch instability issue.
EASA writes “excessive pitch attitude can occur in certain conditions and during specific manoeuvres. This condition, if not corrected, could result in reduced control of the aeroplane.”
We analyze how this is similar or different to the Boeing 737 MAX pitch instability issues.
NOTE 2: We have got a further update from Airbus, see below.

July 18, 2019, © Leeham News: Airbus’ new A321XLR is labeled as an Boeing NMA killer. It shall, with its capability to fly the same routes as the NMA, nibble away on its market space.
This discussion takes the Airbus passenger and range data for the A321XLR and compares it with the announced capabilities of the NMA. As we will see, it’s not that simple.

July 15, 2019, © Leeham News: There are 14 new and derivative aircraft scheduled for entry into service (EIS) through 2027. This rises to 16 if Boeing launches the New Midmarket Aircraft (NMA).
But there are plenty of uncertainties around precise EIS hanging over some of these.
LNA sees the Boeing 777X EIS slipping into early 2021. China’s C919 is now slated for a 2021 EIS, but development has been tricky and delays have been common. Russia’s MC-21 flight testing has been slow and international sanctions hang over this aircraft.
Mitsubishi’s MRJ90, now called the M90, is slated to enter service next year. It, too, has been plagued by delays. The redesigned MRJ70, the M100, moves from a 2021 EIS to a planned 2023 EIS—but given the MRJ90’s history of delays, the company has to persuade the industry no more slippages are likely.
Here is a rundown by year and aircraft of the EIS dates.
July 15, 2019, © Leeham News: Boeing can’t catch a break.
Some may argue it doesn’t deserve one, given what’s come out about the 737 MAX development. And the sloppy production of the 787 at the Charleston (SC) plant. And the FOD issues with the KC-46A at the Everett (WA) plant.
To be sure, Boeing has gotten a lot of bad press it’s deserved. But last week, two pieces of news had connections to the MAX that were (1) overwrought and (2) unwarranted.
