FAA Clears Boeing to Begin TIA Phase 4B Testing on 777-9
The FAA has cleared Boeing to begin Type Inspection Authorization Phase 4B testing on the 777-9, marking a significant step in the 777X program’s long-delayed type certification. Boeing Commercial Airplanes chief executive Stephanie Pope confirmed the clearance, saying the FAA had cleared the way to start the remaining flight tests. TIA is the FAA’s structured phase-by-phase inspection and flight-test framework that aircraft must complete before receiving a type certificate permitting commercial passenger operations. The 777X program has faced years of regulatory setbacks since its original certification timeline, making the Phase 4B authorization a closely watched milestone for Boeing and its airline customers awaiting delivery.

Rolls-Royce Secures USAF Funding for Orpheus Autonomous Fighter Engine
Rolls-Royce has secured United States Air Force funding for the Orpheus engine in support of the service’s Collaborative Combat Aircraft program. The USAF’s CCA initiative aims to develop autonomous fighter drones capable of operating alongside crewed combat aircraft. The Orpheus is a compact turbofan designed specifically for the propulsion requirements of smaller autonomous platforms. The CCA Increment 2 contract award places Rolls-Royce among the engine developers competing to power the next generation of uncrewed combat aircraft the Air Force intends to field. The selection underscores growing demand for propulsion systems optimized for autonomous, expendable, or semi-expendable unmanned combat aircraft designs.

Airbus Details Next Generation Single Aisle Architecture in New Analysis
Airbus has continued outlining the architecture of its planned successor to the A320neo family in the fifth installment of a technical analysis series published by Leeham News and Analysis. The New Generation Single Aisle program remains under study as Airbus weighs the structural and propulsion technologies that will define its next narrowbody airliner, with the aircraft expected to begin deliveries in the latter part of the next decade. The series examines the overall configuration and design philosophy the manufacturer is developing, and forms part of ongoing industry discussion about how far the program will depart from the current A320 family in fuselage design, wing architecture, and systems integration.

NASA X-59 QueSST Achieves First Supersonic Flight at Mach 1.1
NASA’s experimental X-59 QueSST aircraft completed its first supersonic flight on June 5, reaching Mach 1.1 (713 mph) at 43,400 feet during an 81-minute sortie from Edwards Air Force Base. Test pilot Jim “Clue” Less collected data on flying qualities at subsonic and supersonic speeds. The X-59 is powered by a single F414-GE-100 engine and features a long tapered nose covering nearly one-third of its length, designed to break up shock waves and keep the sonic boom below 75 perceived decibels. NASA Administrator Jared Isaacman said the team expects to reach Mach 1.4 in coming days, the target speed for community overflight acoustic validation tests.

Germany and France End Joint New Generation Fighter Program Under FCAS
Germany and France have decided to end the joint New Generation Fighter component of the Future Combat Air System program. German Chancellor Friedrich Merz conveyed the decision to French President Emmanuel Macron at the EU-Western Balkans Summit in Montenegro. The FCAS program was first announced at ILA Berlin 2018, with Spain officially joining in 2020. It stalled at Phase 1B of technological development after Dassault Aviation and Airbus Defence and Space were unable to agree on workshare—Dassault sought a greater share while Airbus demanded equal division. A formal announcement is expected at ILA Berlin. Both nations will continue jointly developing the FCAS combat cloud and drone network.

AIAA Aviation Forum 2026 Opens in San Diego with 1,000-Plus Presentations
The AIAA Aviation Forum 2026 opened June 8 in San Diego, California, bringing researchers, engineers, and industry representatives together for five days of aeronautical science and engineering exchange. This year’s theme, “From Velocity to Altitude—Accelerating Toward Tomorrow,” captures the forum’s focus on advancing aviation technology. The technical program features more than 1,000 presentations spanning over 20 research topics including fluid dynamics, applied aerodynamics, thermophysics, air transportation systems, and multidisciplinary design optimization. Three full days are dedicated to the Electric Propulsion and Advanced Technologies Symposium, with additional sessions on artificial intelligence, hydrogen propulsion, and autonomous flight systems.

Gulfstream Debuts G400 and G300 Mock-Ups at European Showcase
Gulfstream has debuted full-scale mock-ups of its G400 and G300 business jets at a European display event, giving regional customers and operators their first opportunity to assess cabin dimensions, seating configurations, and interior layouts in person. The displays allow prospective operators to evaluate both aircraft before finalizing bespoke specifications ahead of delivery. The G400 and G300 occupy Gulfstream’s midrange business jet product line. Cabin mock-up tours are a standard phase in new business jet program development, enabling operators to provide direct feedback that informs production interior decisions and confirms that the aircraft meets their operational and range requirements before entering the production pipeline.
