Bjorn’s Corner: New aircraft technologies. Part 34. Design for Certification
October 13, 2023, ©. Leeham News: We are discussing the Detailed design phase of an airliner development program. We have discussed program management methods, development techniques, tools for Detailed design, that improved production methods are as important as improved technology, and that the interaction with the suppliers is key.
But another consideration that affects detail design is the influence of the Certification process. Certification has a major influence on the program work in every step of the aircraft program.

October 12, 2023, © Leeham News: We do an article series about what can be the next development for Airbus’ most popular aircraft, the A321neo. We started with the base data last week to understand the present aircraft and its limitations.
Now, we use our Airliner Performance and Cost Model (APCM) to look at possible changes that can increase the capacity and efficiency of the aircraft and what can be achieved at a reasonable cost.
Summary:
- The capacity of the A321neo can be increased within a rather limited project.
- The more challenging part is not to lose range and field performance from the capacity increase.
Pontifications: For aviation geeks and historians; Boeing’s next airplane
By Scott Hamilton
Oct. 10, 2023, © Leeham News: For aviation geeks—and there are plenty of us—and historians, a resource that is the best single place I’ve seen is Chris Sloan’s TheAirchive.Net – The Hub of Air Transport History. Sloan—who joined LNA yesterday as a writer—started The Airchive 20 years ago. It’s a compilation of just about everything a geek or historian could imagine: timetables, route maps, brochures, information about airport terminals, cabins, cockpits and so much more.
Sloan’s data of course includes photos of airplanes, memorabilia, safety cards, boneyards, and even menus. He also has a section highlighting museums. This section includes many well-known museums and also some I’d never heard of.
Personnel changes for LNA announced
Oct. 9, 2023, © Leeham News: Leeham News announces several personnel changes today.
Bryan Corliss, who has been a Contributor to LNA for years, is leaving to become a corporate communication specialist with The Society of Professional Engineering Employees in Aerospace (SPEEA). SPEEA is the engineers and technicians union for Boeing and Spirit AeroSystems. LNA is sorry to lose Corliss’ depth of aerospace and labor knowledge. Corliss’ email with LNA will be active for a month so readers may connect with him.
Earnings season about to begin. Here’s what to watch for.

Oct. 9, 2023, © Leeham News: Earnings season reporting is about to start and there are some key things to look for. The first companies, including Boeing, begin reporting the week of Oct. 23.
A few companies already raised red flags. Boeing said it will report a loss in the third quarter, which ended Sept. 30, because of problems at Spirit AeroSystem. Spirit Aero builds the entire fuselage for the Boeing 737 and the nose sections for the Boeing 787, 777, and 767/KC-46A. Spirit Aero has been plagued with quality control issues, delaying deliveries and requiring rework of planes already produced or in final assembly at Boeing.
When Spirit Aero sneezes, Boeing can catch the cold.
The aforementioned problems continue to push Spirit Aero into financial disarray. LNA has reported extensively on its financial condition and trends.
Another Spirit, the US-based ultra-low-cost airline, is also headed in the wrong direction. LNA doesn’t normally cover airline earnings—there are plenty of outlets that do—but in this case, Spirit Airlines has a major outstanding order from Airbus. Spirit Airlines is also the subject of a merger application with JetBlue, another major Airbus customer.
Spirit Airlines recently adjusted its third quarter guidance significantly downward. It now forecasts a 3Q loss margin of 14.5% to 15.5%, nearly triple the same period last year. A year ago, LNA expressed concerns over the proposed merger between JetBlue and Spirit (JetBlue was the bidding company). Our concerns have deepened. JetBlue may be well advised to exercise a clause that is presumed to be in the merger agreement: Material Adverse Change. Withdrawing from the merger may well be the best course for JetBlue. Acquiring Spirit Airlines may well be a financial black hole for JetBlue.
The supply chain remains stressed. As in the case of Spirit Aero and Boeing, if any key supplier falls down on the job, the Original Equipment Manufacturer (OEM) catches cold.
Here’s a rundown of companies to watch.
Bjorn’s Corner: New aircraft technologies. Part 33. Supply chain
By Bjorn Fehrm.
October 6, 2023, ©. Leeham News: We are discussing the Detailed design phase of an airliner development program. We have discussed program management methods, development techniques, tools for Detailed design and that the production methods today are as important as technology for achieving aircraft performance.
Another decisive part is how to involve and manage the suppliers to a project. The supply chain contributes about two-thirds of the value of an aircraft. Methods and tools to control this part of the project are therefore critical for the program.

Further developments of the A321, Part 2

October 5, 2023, © Leeham News: We look at what can be the next development for Airbus’ most popular aircraft, the A321neo. We looked at the history of the A320/A321 last week and how the aircraft progressively were updated to take more passengers and fly longer sectors.
The series represents more than 50% of the revenue and margin for Airbus. With the latest development, the A321XLR, soon finished, what is next? We use our Airliner Performance and Cost Model (APCM) to look at base data and what changes are necessary to increase capacity and efficiency further.

Summary:
- The A321 is reaching its weight and capacity limits.
- There are ways to lift these limits, but the changes must not break its Airport gate classification.
Risk Adjusted Business: Aircraft and leasing values
By William Loh, International Aviation Advisors and
Dr. David Yu, CFA, Senior ISTAT Appraiser, AAVA Group, NYU Shanghai and Stern
Special to Leeham News
Oct. 3, 2023, © Leeham News: Investing in aircraft has become increasingly popular over many decades now, and for good reason. The returns can be most attractive and well-chosen assets tend to hold their value well over the medium term. Some of them have the option to extend the useful life out to 40 years or more in a freighter conversion.
As with most investments though, owning aircraft involves risk and requires subject matter expertise to avoid surprises and pitfalls. Some of this will involve aircraft selection, understanding industry dynamics, and incorporating these into the modeling of future values/lease rates and equity returns, which have been a focus of ours for several years.
Rather than the traditional method of producing bi-annual static forecasts of future values, our approach has been to develop a simulation model of possible future outcomes. This results in a market-driven probability distribution of the future asset value, rather than a single point forecast (rarely achieved in practice). Most traditional forecasts are discrete points including the classic high/low/base versions. Our forecasts are updated whenever it is appropriate based on market changes.

Mammoth quietly drops trade secrets theft lawsuit
By the Leeham News Team
Oct. 2, 2023, © Leeham News: Mammoth Conversions quietly dropped its long-running trade secrets lawsuit against Sequoia Conversions, a competitor, for alleged trade secrets theft.
Mammoth and Sequoia settled and dropped the lawsuit, with each side paying its own costs, on Sept. 8. The case was filed in the US District Court in Southern California. Sequoia’s David and Wayne Dotzenroth were also defendants. The action against them also was dropped. The case was scheduled to go to trial in January.
Mammoth previously dropped its lawsuit against the University of Wichita’s NIAR engineering center and Split Rock Aviation, a consulting firm working with Sequoia. Each side bore its costs in these dismissals.
