Oct. 4, 2021, © Leeham News: Engine and airframe makers are well on their way to becoming fully capable of using Sustainable Aviation Fuel (SAF). But the industries providing SAF are way behind in meeting the potential demand.
Rick Deurloo. Sr. VP & Chief Commercial Officer at Pratt & Whitney said one major US airline would use all currently available SAF in one day.
“The challenge will be the feedstock. How do we grow that technology or grow that ability to provide the feedstock so when we do have 100% SAF-capable aircraft and engines, we have the energy to go with it?” Deurloo said in an interview with LNA at the IATA AGM this week in Boston.
Airlines around the world are partnering with different companies to develop this technology, he said.
PW is already 50% capable and has a “clear path” to getting 100% capable within two years. But there is not enough feedstock in the world today do fill the 50% capability.

Sept. 28, 2021, © Leeham News: Airbus is streamlining some of its production of the A220 to reduce costs and the time to assemble the airplanes at its Montreal and Mobile plants.
Florent Massou, the SVP and Head of the A220 program, told LNA the company wants to shave 50% of the final assembly time for the A220. There will be an unrevealed cost reduction, which Massou declined to reveal. But he said it isn’t a one-for-one cost reduction.
Final assembly typically runs 5% to 8% of the total cost of the airplane, according to Boeing’s touch labor union, the IAM 751. Whether this equates to the A220, which began life as a Bombardier aircraft, is unknown.

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

IAI Bedek Big Twin Boeing 777-300ERF passenger-to-freighter conversion. Lessor GECAS, now part of AerCap, was the launch customer of this, the first 777 P2F program. Source: IAI Bedek.
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.

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.
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.

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.

September 14, 2021, ©. Leeham News: Boeing released its yearly commercial aircraft demand forecast today. Over the next 20 years, the demand for single-aisle aircraft is past pre-covid levels at more than 32,000 aircraft, with widebodies down 8% compared to 2019 at 7,500 aircraft, Figure 1.
The forecast for freighters is up at 890 aircraft making a total of 43,600 aircraft until 2040, the level of the 20 years forecasts before the pandemic.
Sept. 13, 2021, © Leeham News: Tomorrow night the US PBS network broadcasts an hour-long special examining the Boeing 737 MAX crisis.
Here is a preview. Afterward, the show will stream on PBS’s Frontline website.
I sat for a long interview for the investigation, which was a combination of reporting by Frontline and the New York Times. I haven’t previewed the show, so I don’t know how much of my interview—if any—survived the editing. But one area of the focus of the interview was how Boeing came to develop the MAX.

Air Wars is available here.
Following the crashes of Lion Air and Ethiopian Airlines five-month-old MAXes, one of the allegations that emerged was that Boeing rushed the development of the airplane.
It’s true that Boeing decided within two days to launch the MAX program. It’s not true that development was “rushed,” in the most common use of the word. Boeing developed what became known as the MAX in parallel with an entirely new airplane concept that would have replaced the 737 Next Generation airplane. It’s what Boeing does: study two or more concepts as engineers and the executives decide what the next airplane will be.
The basic design was on the shelf, ready to go when Airbus forced Boeing’s hand on the cusp of a huge order from American Airlines for the A320ceo/neo family. When Boeing learned of this, the decision was rushed, within two days, to launch the re-engined 737 rather than a new airplane design.
In my new book, published Sept. 1, Air Wars, The Global Combat Between Airbus and Boeing, I outline just how the MAX came to be and how Airbus maneuvered Boeing into launching the program. The book is available globally on Amazon here.
Here is an excerpt from Chapter 1, one of three chapters about the neo-MAX development.

Sept. 13, 2021, © Leeham News: The first COMAC C919 is supposed to be delivered to China Eastern Airlines before the end of the year.
If so, it will be the milestone of the program launched in 2008, 13 years ago, becoming one of the longest launch-to-EIS in aviation history. COMAC’s ARJ 21 took one year longer. This regional airliner program was launched in 2002. Entry-into-service was in 2016.
The C919 is China’s direct challenge to the Airbus A320 and the Boeing 737. Similar in appears to the A320, for which there is an assembly line in Tianjin, the C919 is powered by the CFM LEAP 1C and a domestically-produced engine. But the C919 only has an advertised range of 2,200-3,000nm. The A320 and 737-8 have ranges of 3,500 and 3,550nm, respectively.
COMAC forecasts producing 150 C919s a year by the middle of this decade. Achieving this rate in this period should be a major challenge. Based on normal learning curves, a more realistic ramp up to 150 a year will take until early 2031.
