June 17, 2019, © Leeham News, Paris: As the international aerospace community and media gathers here this week for the Paris Air Show, the Boeing 737 MAX is the elephant in the room.
The focus obviously is on when the MAX will return to service worldwide.
A few people are already looking beyond this, to how quickly Boeing will ramp production back up and how quickly the backlog of completed airplanes will be delivered to airlines and lessors.
The grounding appears that it will go on much longer than expected.
June 17, 2019, © Leeham News: The Paris Air Show opens today and the elephant in the room is the Boeing 737 MAX.
There is no telling when the airplane will get FAA approval to return to service. According to some news reports, Boeing will hasn’t turned over the MCAS revisions to the FAA for review, testing and approval.
The acting administrator of the FAA said he expects the MAX to be back in the air by the end of the year. Some leapt to the conclusion this means December—and it may, but let’s remember September, October and November are before the “end of the year,” too.
There’s no telling how other global regulators will act, and when, to conduct their own review and approvals. Airlines would like a global action. It’s tough to tell customers one country sees the airplane as safe but others don’t.

Now we look at the challenges hybrid transport aircraft face when competing with today’s turbofan airliners.

June 13, 2019, © Leeham News.: Mitsubishi Aircraft Corp (MITAC) has done more than a rebranding and new livery in creating the SpaceJet out of the MRJ70.
It’s changing the design, its materials and several parts of the interior to accommodate more passengers than the MRJ70.
Here is a technical analysis of the aircraft, based on information released today and our own Aircraft Performance Model.
We describe the changes MITAC made to the MRJ70 to end up with the M100 SpaceJet and what these mean for passengers and operators.

June 13, 2019, © Leeham News: Last week we looked at the route structures an Airbus A321XLR could support compared with the original A321LR. We could see the A321XLR is a more flexible long-range aircraft than the A321LR.
It covers trans-Atlantic routes from Mid-US to mid-Europe and it can for several route types replace larger aircraft, thus allowing increased frequency on existing routes or the start of new thinner routes than possible with widebody aircraft.
This all assumes the economics of the A321XLR and a widebody like the Airbus A330neo or Boeing 787 are comparable. We use our Aircraft Performance Model to find out.

The discussion was part of my previous series on Electric aircraft, but it was in the comment section. Here is a more exhaustive run through of the main reasons.
