October 17, 2019, © Leeham News: FlightGlobal writes Boeing is investigating re-engining the 767-400ER with GE GEnx engines to produce a new freighter and perhaps a passenger aircraft as a replacement for the NMA project. Development costs would be lower and it would be easier to get a business plan which closes for the upgraded 767 than for the NMA.
We commented on the idea earlier in the week and here follows a technical analysis of what re-engining the 767 would bring.

Introduction
Sep. 30, 2019, © Leeham News: It hasn’t been an easy year for the Airbus A380 program since the end of production was announced in February.
Lufthansa announced in March that Airbus would buy back six A380s in 2022/2023 as part of a follow up order for 20 A350-900s. Air France intends to retire its Superjumbo fleet by 2022. Emirates retired two aircraft that were less than seven years old.
A number of factors are leading airlines to prematurely retire their A380s.

September 5, 2019, ©. Leeham News: Last week, we examined how a longer-range model of Boeing’s 787-10 would look like. We designed a 787-10ER version (ER for Extended Range) by increasing the Maximum TakeOff Weight of the aircraft. We also did some other adjustments to accommodate the increased weight.
We now compare the resulting aircraft with its nearest competitor, the Airbus A350-900. How would a 787-10ER stack up against an A350-900?

August 1, 2019, © Leeham News: We wrap up our study of what part of an NMA market the Airbus A321XLR could capture with looking at the difference in available engine technology between the A231XLR and the NMA generation of airliners.

April 22, 2019, © Leeham News: If there remains any doubt that Boeing’s prospective New Midmarket Airplane (NMA) won’t be ready for entry into service (EIS) by 2025, it should be dispelled by now.
The grounding of the 737 MAX March 13, which is likely to continue well into the summer, will delay any launch of the program—should Boeing proceed.
The Board of Directors is unlikely to approve Authority to Offer (ATO) the NMA for sale as long as the cash flow for the MAX is outgoing and not in-coming.
Although this has its own impact on the NMA timing, it’s not the critical factor.
Last week, it was revealed that the CFM LEAP engine on the MAX (and the Airbus A321neo) has a problem called coking, which led to the contained engine failure of a Southwest Airlines MAX being ferried from Orlando (FL) to Victorville (CA) for the grounding of the Boeing airplane (see here and here). It’s the latest in a long line of engine maker problems with their current generation of powerplants.
This issue is unrelated to the MAX MCAS grounding. It also affects some engines on the A320neo family.

March 4, 2019, © Leeham News: Another week, another NMA story.
For an airplane that doesn’t exist, the prospective Boeing NMA continues to dominate much of the aerospace news.
Last week’s announcement by Rolls-Royce that it withdrew—in December, as it turns out—from the competition to power the NMA prompted a flurry of stories in aerospace media, including LNA.
Some stories suggested RR’s withdrawal meant Boeing was getting closer to launching the airplane.
Boeing, in January, said Authority to Offer might come this year and program launch had moved from 2019 to 2020.
Two prominent consultants predicted at the Pacific Northwest Aerospace Alliance conference last month the odds were 60-40 or 65-35 Boeing would proceed.
Maybe, but I have to tell you that conversations I had last week in the wake of the Rolls announcement are not encouraging.
