Airbus’ TwoTwenty, its first real business jet
By Bjorn Fehrm
September 28, 2021, ©. Leeham News: When Airbus got the A220 airliner series from Bombardier, it also got the base for a competitive business jet.
Airbus, like Boeing, has produced Corporate Jets under its ACJ (Airbus Corporate Jets) since 1997 by converting its passenger A319, A320, A330, and A350 to one-off jets for Corporations, States, or wealthy individuals.
With the business jet based on A220-100, this changes. It’s no longer a one-off production but a fully-fledged Bizjet like the Gulfstream 650/700 or Bombardier Global 6500/7500, produced in series and with a semi-custom modular interior.

Sept. 27, 2021, © Leeham News: The race for the Boeing 777 P2F Freighter conversion is on.

There are three companies in various stages of development. The first, IAI Bedek, announced its conversion process in 2019 with an order from the giant lessor, GECAS (now a part of AerCap). The second is a program driven by Nair Werx of Wichita (KS) and marketed by Sequoia Aircraft Conversions. The third is the recently announced Mammoth Freighter Conversions of California and Florida.
IAI has cut metal. Mammoth is test-flying a 777-200LR for stress and technical analysis. NAIR is in the pre-production Engineering Phase.
Let’s take a moment to understand the process of a P2F Conversion.
Bjorn’s Corner: The challenges of airliner development. Part 22. Flight tests
By Bjorn Fehrm, Henry Tam, and Andrew Telesca.
September 24, 2021, ©. Leeham News: Last week, we looked at the necessary Production Certificate for the production of our airplanes.
Now our program plan has approached the mid-phase of the Post-Launch phase. We start assembling our test aircraft to get to flight tests.

Is cargo capacity deciding the airliner variant?

By Bjorn Fehrm
Introduction
September 23, 2021, © Leeham News: In last week’s article, we put the question: Has the increased cargo pricing started to affect the choice of airliner variant?
We listed recent decisions between the Boeing 787-8 and -9 or Airbus A330-900 and A350-900 where the traffic levels post-pandemic would motivate the smaller variant, but the larger was retained or selected.
It makes you wonder whether the higher cargo capacity of the larger variant compensates for flying a larger cabin at a lower load factor? We make a cost and revenue analysis to find out.
Summary
- Cargo was an additional revenue stream on top of the main source, the passenger traffic.
- The lower traffic levels for international long-haul traffic and the increase in cargo pricing have changed this. Cargo is now as important in the decision of which aircraft to choose as the passenger capacity.
Airbus presents their CityAirbus UAM
By Bjorn Fehrm
September 21, 2021, ©. Leeham News: Airbus helicopter division presented their entry for the UAM market today at the Airbus 2021 Summit in Toulouse.
It was a presentation of a vehicle and ecosystem that has been cooking for years. After two demonstrators that tested different aspects of eVTOL flight and thousand of hours on supercomputers and in wind tunnels, the final CityAirbus is here, Figure 1.
Its configuration is as unique as Airbus’ approach when presenting it.

HOTR: Lockheed reveals tanker info: it’s all about America
Sept. 21, 2021, © Leeham News: Lockheed Martin (LMT) last week revealed its dedicated product launch web site page of 
the LMXT aerial refuel tanker. The LMXT uses the Airbus A330 MRTT as the platform for the US Air Force’s KC-Y competition for which initial information requests have been issued.
LMT and Airbus partnered in 2018 in anticipation of the KC-Y program, originally intended to replace the aging Boeing (nee McDonnell Douglas) KC-10. KC-Z was to follow, an entirely new concept in aerial refueling tankers.
KC-Y is now recast as a replacement for 140-160 Boeing KC-135s. It will be a follow-on to the original KC-X program, which was won by Boeing after three tries. Boeing has 179 orders for the 767-200ER-based KC-46.
Pontifications: 8-year old A330-300 converted to freighter, reflects weak market
By Scott Hamilton
Sept. 20, 2021, © Leeham News: An 8-year-old Airbus A330-300 was converted recently from passenger to freighter configuration by EFW.
Actually, says EFW’s Wolfgang Schmid, the airplane is not quite eight. It is the youngest A333 to be converted.
I can’t remember an airplane of any type this young being converted from passenger to freighter. The market value of an eight-year-old aircraft is way too high. Operating economics are well within airline requirements at this age. Aircraft historically become conversion candidates no sooner than 15 years of age and more commonly not before 20.
Behind the latest Boeing CMO

By Vincent Valery
Introduction
Sept. 20, 2021, © Leeham News: Boeing Commercial Airplanes (BCA) released its latest Commercial Market Outlook (CMO) last week. While the latest total 20-year outlook for commercial aircraft remains below 2019 (43,610 vs. 44,040), it increased by 500 units compared to the previous year.
BCA highlights the headline number of aircraft deliveries to point out the bright long-term growth prospects for the commercial aviation market. The report states that the COVID-19 pandemic erased two years’ worth of growth but did not materially affect long-term prospects.
The delivery figures rely on a large number of assumptions, including market segment and region. LNA takes a deeper look at those assumptions, notably regarding delivery and production rates.
Summary
- Converting to more understandable metrics;
- Assessing the impact of slower 2021 deliveries;
- Plausibility of twin-aisle prospects for the 2020s;
- Can production follow?
Bjorn’s Corner: The challenges of airliner development. Part 21. Production Certificate
By Bjorn Fehrm, Henry Tam, and Andrew Telesca.
September 17, 2021, ©. Leeham News: Last week, we looked at the Production facilities and tooling. In order to bring in revenue, we need to deliver aircraft.
But to have the right to deliver aircraft we need a Production Certificate in addition to our Type Certificate for the design. We need to start the work to get a Production Certificate well before we flight test the aircraft and complete the type certification work, Figure 1.
