Introduction
June 20, 2022, © Leeham News: New airplane programs used to come to market in four years. Now, the launch-to-entry-into-service period has been seven years or more. (Chinese and Russian programs take even longer.)
Boeing launched the 787 in December 2003. EIS was October 2011. Airbus’ A350, launched in response to the 787 in 2004, went through several iterations which added time to the program. Delays added more time. EIS was in January 2015.
Bombardier’s C Series was launched in 2008. EIS was in July 2016. The Boeing 777X was launched in 2013. EIS is now targeted for 2025. Boeing launched the 747-8 in 2005. EIS was in 2011. The Boeing 737 MAX was launched in July 2011. EIS was May 2017. Airbus’ A320neo was launched in December 2010. EIS was in January 2016.
Boeing has been discussing the New Midmarket Airplane (or whatever it was called throughout changing nomenclature) since 2012. It still hasn’t launched the program. Once it does, how long will it take to enter service?

Any new program is a multi-year, multi-million investment that, in the worst case, can take decades before recovering the initial development and production ramp-up expenditures.
Several recent programs, notably the 777X, have faced significant delays between the envisioned and actual start of deliveries to airlines.
Boeing claims that advances in manufacturing techniques will reduce the time required to develop the next aircraft program. However, regulatory scrutiny is higher nowadays and the aircraft built are more complex than in previous generations.
LNA analyzes how the time between the program launch and entry into service has evolved since the beginning of the Jet Age. The goal is to find whether there is a trend and in what direction. The analysis focuses on Airbus, Boeing, Lockheed, and McDonnell Douglas.
Summary
- An unmistakable trend;
- The latest clean sheet designs took significantly longer;
- Engine development dictates recent derivative program timelines;
- Future program considerations.
Pontifications: Why I’m cautiously optimistic about Boeing’s future
By Scott Hamilton
June 20, 2022, © Leeham News: Boeing still has a deep hole to climb out of. There’s still plenty of opportunity for missteps along the way. But I’m cautiously optimistic about Boeing’s future.
Here’s why.
- There are tangible things to point to that are indicators Boeing internally is now optimistic about its long flirtation with disaster.
- Despite well-deserved skepticism and concern about when, or even if, Boeing is going to launch a new airplane program, signs point to “yes.” These go beyond the usual rhetoric that often has a hollow public relations ring.
- The signs are there that Boeing at long last appears near resuming delivery of the 787, a critical step in its recovery.
- Clearing the inventory of the 737 has been infuriatingly slow. But if one had been paying close attention, this shouldn’t have been a surprise—and China’s refusal so far to authorize its airlines to return the MAX to service is but one issue.
FAA adopts ICAO 2027 emissions, noise rules; death knell for new production 767F, 777F
- 787F, NMA-F are natural conclusions to consider for a successor to 767F
By Scott Hamilton
June 16, 2022, © Leeham News: The US Federal Aviation Administration yesterday announced it will adopt the emissions and noise rules proposed in 2017 to reduce emissions and noise in commercial jets and turboprops by 2027. Failure to comply means the offending airplanes can’t be produced from 2028. The rules won’t affect airplanes already produced.

The FAA’s move means that Boeing’s popular 767-300ERF and 777-200LRF can’t be produced from 2028.
The rules were adopted by the global organization ICAO, the International Civil Aviation Organization. But countries individually must adopt them. The FAA proposes a new rule to bring the US into compliance. By federal law, the FAA proposed rule must be published in the Federal Register. A comment period follows, after which the FAA either moves forward with the rule as proposed, revises it, or rejects its proposed rule based on the comments.
Boeing already announced a successor to the 777F: the 777-8F, a member of the 777X family. Entry-into-service is slated for mid-2027 before the rules take effect. Boeing doesn’t have a solution for the termination of the 767F production.
Migrating advanced processes from Defense to Commercial isn’t a cakewalk for Boeing

June 13, 2022, © Leeham News: Boeing’s CEOs, David Calhoun and his predecessors Dennis Muilenburg and Jim McNerney, said repeatedly the next Boeing airplane (NBA) will be as much as about production as it will be about the airplane. In fact, Calhoun says production is key to designing, producing, and delivering a less expensive airplane that will underpin the value proposition going forward.
Engine technology advances might achieve a 10% reduction over today’s CFM LEAP and Pratt & Whitney Geared TurboFan engines. So, advanced design and production is key to the business case for the NBA.
Despite using these advancements on Boeing defense programs (the T-7 Red Hawk trainer and MQ-25 unmanned aerial refueling airplane), assimilating them into commercial airplane development and production has high hurdles.
Summary
- Boeing has had mixed success using advanced technology design and production on its current commercial programs.
- Regulatory approvals will be challenging.
- Engines will be 10% better than the LEAP and GTF—but are these the correct comparisons?
Pontifications: Some customers anticipate up to year delay in certification of A321XLR
By Scott Hamilton
June 13, 2022, © Leeham News: Airbus scheduled the first flight of its Xtra Long Range A321XLR Wednesday.
Some customers think certification of the airplane will be delayed up to a year as Europe’s EASA and the USA’s Federal Aviation Administration demand changes to the integrated aft fuel tank that gives the XLR an advertised range of 4,700nm.
That was the consensus of those I talked to who gathered last week at an industry event in Chicago. Airbus already said the XLR certification will be delayed by a few months as regulators review how the fuel tank is integrated into the airplane.
How Boeing is Rebuilding Engineering Excellence

Introduction
June 9, 2022, © Leeham News: As described in our Monday article, Boeing is preparing for its Next Boeing Airplane (NBA). At the same time, the company is hard at work to ensure this will be no repeat of the 787 and 737 MAX program debacles.
The 2022 Chief Aerospace Safety Officer Report was issued two weeks ago. It gives insight into the work that shall ensure such failures won’t happen again. Here is what the report says about how Boeing is rebuilding its Engineering Excellence.
Summary
- The 787 and 737 MAX failures came from a company culture where engineering excellence played second fiddle to short-term business objectives.
- Boeing has now made changes from the board level to how it organizes its engineers. These changes go in the right direction, but will they be enough?
Boeing’s steps toward its next new airplane

June 6, 2022, © Leeham News: Boeing will launch a new airplane program, vows David Calhoun, CEO of The Boeing Co. Stan Deal, CEO of Boeing Commercial Airplanes (BCA), said Boeing is going through the “prerequisites” for a new airplane, according to Bloomberg news. Skeptics remain doubtful, noting research and development spending remains at historic lows and definitive action remains out of sight.

“The dilemma for Boeing is whether to wait to see if the new technology pans out, ‘or do we run the propulsion system one more time before we go to that next technology suite?’ Deal said in a virtual panel discussion hosted by the Royal Aeronautical Society,” Bloomberg reported in January. Calhoun, in an appearance at Bernstein Research Friday, said engines aren’t advanced enough for a new airplane to counter the Airbus A321neo.
Nevertheless, if one looks carefully, steps moving toward a new airplane program are there. LNA analyzed Boeing’s recent job hiring spree, which includes engineers, technicians, and other positions. Some of these are specifically for new airplane jobs. Boeing last year spent millions of dollars above contract requirements with SPEEA, its professional union, to retain engineers and technicians. Last year, Boeing named a new leader for its Digital Design Team for a new airliner. The Design Team recently studied lessons learned from defense programs for application to BCA.
Airlines impacted by new aircraft delays
By Vincent Valery
Introduction
June 6, 2022, © Leeham News: LNA recently discussed the certification delays on all the current aircraft or variants under development: Airbus A321XLR, Boeing 737-7, 737-10, and 777X. Dreamliner deliveries have also been halted for 18 months now (except for a dozen last year).

Airlines consequently face significant delivery delays on the aircraft they ordered. American Airlines publicly stated the Boeing 787 delivery delays have caused it to operate a smaller international network than envisioned. Air Lease Corp repeatedly noted that every airplane on order from Airbus and Boeing is delayed. It’s now been reported that CFM LEAP engines for the Airbus A320neo and Boeing 737 MAX families will be delayed for 4-6 weeks.
As passenger traffic recovers, the delivery delays will hamper airlines’ ability to capitalize on more robust demand. Higher fuel prices also mean that they cannot mitigate the impact by operating as many newer-generation aircraft as envisioned.
LNA analyzes the delivery schedule envisioned by Airbus and Boeing on the above programs that were in place before the delay announcements. The goal is to single out the most affected customers.
Summary
- Deliveries concentrated with one customer on the 737-7 and 737-10;
- A more diverse A321XLR and Dreamliner delivery base;
- Renegotiating 777X delivery timelines.
Pontifications: From Just in Time to Just in Case
By Scott Hamilton
June 6, 2022, © Leeham News: Delivery delays by Airbus and Boeing are well-known in today’s recovering environment. The reasons vary from supply chain challenges affecting both companies to Boeing’s suspended deliveries of the 787 and slower-than-expected deliveries of the 737 MAX.
Airbus Canada delivered only five A220s in May vs 10 that were planned. Ten deliveries are planned this month but hitting this target (and 70 for the year) may be problematic. LNA previously detailed the delays for the A220. Airplanes are coming off the final assembly lines without completed cockpits. Embraer is affected by a shortage of seats. CFM’s delivery of LEAP engines for the A320neo and 737 MAX is delayed.
It’s not just the big-ticket items that are hurting the Big Three airframe manufacturers. It’s the little stuff. The supply chain is only as strong as its weakest link. Some smaller suppliers can’t get the products they need from their suppliers. And some, already facing workforce shortages before the COVID-19 pandemic, are short of workers today.
These issues are causing a shift in what used to be the mantra of Just in Time product deliveries.
Boeing is trying to help its supply chain on a number of levels, said Mike Nieman, Regional Director of Globalization & Supplier Development, during the I-90 Corridor Conference last week in Coeur D’Alene (ID). The group represents the aerospace industry from Spokane (WA) through Idaho and into Montana along the Interstate 90 highway corridor.
One or Two hops cheapest for long flights? Part 2

Introduction
June 2, 2022, © Leeham News: We tested the notion that it’s more economical to divide a long flight into two shorter flights last week. The test was a typical long-range flight of 11 to 12 hours.
We found that if all operational costs are counted (the so-called Cash Operating Costs, COC), the theory didn’t work. You gain on fuel costs, but you are doubling other costs like landing fees, etc.
Now we test the theory on an Ultra Long Range (ULR) flight, using our Performance and Operational Cost model.

Summary
- The widespread idea of two shorter flights being more economical than a single long flight applies to ULR flights.
- The theory says this is because a long flight takes more fuel than two shorter flights. It’s not the main reason why the theory holds for ULR flights.
