December 01, 2023, ©. Leeham News: We are discussing the different phases of an airliner development program. After covering Conceptual, Preliminary, and Detailed design, the manufacturing of prototypes, and their roles in flight tests, we now look at Production.
Last week, we explained why the focus on the production phase has increased for recent and future projects. Now we go deeper into why the production phase and how it runs is so important.

May 4, 2023, © Leeham News: In our series about the viability of the business plans for small airliners (nine to 50 seats), we have covered how energy and fuel consumption scales with the size of the airliner.
The cost factor we examine today is the maintenance cost for keeping an airliner fit for purpose and safe.
We use the Leeham aircraft performance and cost model to get the data for the maintenance costs for airliners going from nine to 200 seats.

Aug. 10, 2020, © Leeham News: With Boeing likely to consolidate 787 production in Charleston (SC), reflecting a rate of 6/mo, the future of assembly in Puget Sound rears its head again.
LNA outlined Aug. 3 why Everett is the ideal location to assemble the Next Boeing Airplane (NBA).
Boeing’s product line also requires a new airplane in the 100-150 seat sector. Airbus’ A220-100/300 and, nominally, the A320neo (but not the A319neo) fill this sector. (The A320neo was originally designed as a 150-seat airplane. It now is commonly configured in the 150-180 seat size.)
Airbus has a design for an A220-500, which could replace the A320.
Boeing needs an efficient competitor to the current A220 plus a replacement for the 737-7 and, eventually, the -8.
And it probably won’t be assembled at the Boeing 737 plant in Renton.
