Boeing Commences 777-8 Freighter Production
July 28, 2025, (c) AIN: Boeing has officially begun series production of the 777-8 Freighter at its widebody factory in Everett, Washington. About 100 Boeing employees gathered inside the 777X Composite Spar Shop on July 21 to observe as a robotic arm ceremoniously drilled the first hole in a 777-8F wing spar.
It is the first of 938 holes that will be drilled into every wing spar assembled at that location, explained Ben Linder, vice president and chief engineer for Boeing’s 777 and 777-8F programs. Drilling all 938 holes with the automated robot arm, which Boeing calls the Spar Assembly Robotic Cell (SPAC), will take five eight-hour shifts, he told reporters at the Everett facility.

Bjorn’s Corner: Air Transport’s route to 2050. Part 32. Epilogue.
By Bjorn Fehrm
July 25, 2025, ©. Leeham News: In October last year, we began a series on how air transport is performing against the emission goals for the year 2050.
The ambition to reduce and eventually eliminate greenhouse gas emissions began in earnest 11 years ago, when Airbus flew the Airbus E-Fan at the 2014 Farnborough Air Show (Figure 1).

The result of this inspiring flight, which utilized technology that emitted no CO2 or other greenhouse gases (if the batteries were charged with green electricity), was an avalanche of projects from established players as well as upstarts. The optimistic view was that there was a solution to the emissions from airliners.
MTU powers ahead with strong growth amid clarity on tariff impact
By Tom Batchelor
Jul 24, 2025, © Leeham News: German engine manufacturer MTU has posted a 40% rise in operating profit for the first half of 2025 amid what outgoing CEO Lars Wagner called “robust growth” across both commercial OEM and MRO segments.
Adjusted EBIT rose by 40% to €657 million ($773 million) in H1 2025, compared with €470 million in the first half of 2024, with adjusted revenue of €4.1 billion, an increase of 21%, versus €3.4 billion in the first half of 2024.
Wagner said it was an “exceptionally strong” performance for the first six months of the year.
For the second quarter, MTU posted an adjusted EBIT of €357 million euros, higher than Q2 2024’s €252 million and comfortably beating analysts’ consensus estimate of €300m.
Adjusted revenue stood at €2 billion, up from €1.8 billion in Q2 2025.

House Panel Approves Budget Jump for FAA in 2026
House bill to provide a $23.3 billion budget for FAA in 2026
By Kerry Lynch • Editor, AIN monthly magazine
July 18, 2025
The U.S. House Appropriations Committee yesterday approved a $23.3 billion budget for the FAA in Fiscal Year (FY) 2026, more than a $2.3 billion increase over the agency’s funding in the current year and including enough for the hiring of 2,500 air traffic controllers. The FY2026 transportation, housing, and urban development (THUD) bill passed 35-to-28 after a nearly eight-hour markup, drawing opposition from Democrats over funding measures primarily involving the HUD side of the bill.

NASA’s X-59 quiet supersonic research aircraft completed its first taxi test on July 10, the initial movement of the experimental jet under its own power. The test took place at U.S. Air Force Plant 42 in Palmdale, California, and signals the start of the final phase of ground testing before first flight.

RTX Q2 2025 Earnings: Tariff Relief, GTF Stabilization, Strong Demand, and FAA Tailwinds Lift Outlook
By Chris Sloan
July 22, 2025, © Leeham News: RTX delivered strong second-quarter results, supported by continued momentum in the commercial aerospace sector, stabilization in its geared turbofan program, and a significant aftermarket ramp across Pratt & Whitney and Collins Aerospace.
Executives highlighted improving supply chain conditions and growing demand as key contributors, while also noting upcoming FAA modernization investments as a long-term opportunity. Despite ongoing trade friction and a sizeable tariff burden, RTX raised its full-year sales outlook and reaffirmed its free cash flow guidance. Executives said recent developments on the tariff front—including favorable exemptions and successful mitigation strategies—helped soften the impact and improve visibility heading into the second half.
“Our outlook on the impact of tariffs has improved for the year,” said RTX President and Chief Executive Christopher Calio. The company originally expected a $850m tariff headwind in 2025 but has since lowered that figure to $500m. Calio attributed half of the reduction to external developments such as the paused implementation of new rates and the UK’s decision to exempt aerospace components. The remainder, he said, came from the company’s mitigation actions, including optimizing material flows through its supply chain, taking pricing actions where possible, and leveraging trade agreements such as USMCA.
RTX has already incurred approximately $125m in tariff costs through the first half of the year, with the remaining $375m expected in the second half. Of that, $275m is expected to impact Collins Aerospace, and $225m will affect Pratt & Whitney. CFO Neil Mitchill Jr. said roughly $60m and $40m in costs have already been recorded at Collins and Pratt, respectively, during Q2. The total cash impact is expected to reach $600m for the year.
Book Review: Rescuing DOC: The Tale of a B-29’s Triumphant Return to Wichita
Editor’s Note: The Oshkosh Air Show began this week. One of the airplanes to come to the show is the Boeing B-29, “Doc.” LNA’s partner, AINOnline, reviewed the book written by the organization that restored “Doc” to flying status. Here’s a preview of the review with a link to the full review at the bottom of this post. I had the opportunity to fly in “Doc” in 2022. My story is here. — Scott Hamilton.

Rescuing DOC: The Tale of a B-29’s Triumphant Return to Wichita
Effort involved decades of negotiations and restoration, but Wichita’s deep labor pool came through
While many might consider Wichita’s role in aviation history through the recent lens of the numerous Citations, Learjets, King Airs, and other aircraft produced by its manufacturers, the city has carried the sobriquet of Air Capital of the World since the late 1920s.
During World War II, Boeing’s Wichita factory churned out more than 1,600 B-29 Superfortress bombers, and the story of how one of them returned as an abandoned wreck and was restored to become only the second of its type still airworthy is told by Wichita-based Dave Franson, a veteran aviation industry publicist.
Every story requires a protagonist, and in Franson’s new book, Rescuing DOC, that is Cleveland native Tony Mazzolini, who served in the U.S. Air Force during the Korean War as a flight engineer, having enlisted fresh out of high school.
The first half of the book is relayed to the author as first-person narrative and describes how Mazzolini got the idea to rescue a B-29, his quest to locate a viable candidate for restoration, and the eventual hoops he was forced to jump through to gain title to the four-engine bomber that had lain forgotten at the China Lake weapon test range in the California desert for more than four decades.

July 21, 2025, © Leeham News: Our series about “What’s the next new aircraft” was introduced last week, where we look at what potential new aircraft could be introduced over the following decades, and what technologies these would use.
In Part 2 of the five-part series, we introduce some basics around aircraft efficiency and examine what areas these 13 new aircraft aim to improve to enhance their efficiency.
In the following Parts, we will look into these aircraft in more detail and write about how challenging it will be to develop and mature the needed technologies.

July 18, 2025, (c) Leeham News: Now that AIN Media Group has completed the acquisition of Leeham News, I can tell our readers that we will begin to expand coverage at both outlets.
AINonline and LNA will share “previews” of select stories each outlet publishes, with links to the relevant site for the full story. There’s no “schedule” for doing so; the shares will be based on assessing the relevance to our respective readership.
We anticipate further resource-sharing going forward, which will be announced at the time we’re ready to launch these.
For now, here are some recent examples of AIN stories that we will pick up from AINOnline:
