FAA-Approved ACAS X Puts AI Collision Avoidance Authority Above Controllers in Real Time
The FAA has already approved and deployed ACAS X, an artificial-intelligence-augmented collision avoidance system that supersedes air traffic controller authority in real time on commercial aircraft. The system represents one of the most significant integrations of AI into flight safety architecture, yet has generated no political controversy because deployment was structured within established regulatory frameworks. Analyst Vincent Bianco argues the current debate about AI in aviation misses the point—the question is not whether AI belongs in air traffic management, but which functions can be appropriately augmented, at what authority levels, and under what regulatory architecture.

GE Aerospace Industrializes 360 Foam Wash Engine Cleaning Across MRO Network
GE Aerospace is industrializing its 360 Foam Wash engine cleaning technology across its MRO network, extending the system beyond airline line operations into shop-level maintenance. The foam-based process, developed over nine years with more than 6,000 washes completed, saves up to three times more fuel than traditional water-based cleaning by reducing deposit buildup, lowering exhaust gas temperatures, and improving compressor efficiency. Eight licensed airline customers now use the system across GE90, GEnx, CF34, and GP7200 platforms, with full adoption among Middle East GEnx operators. Shop-level application before inspections provides additional diagnostic benefits for maintenance technicians.

Leeham Analysis Traces How Material Science Governed Aircraft Structural Evolution
Björn Fehrm continues his educational series on aircraft structures, examining how material science drove the evolution of airframe design from earliest flights to modern composites. Part 2 traces the progression from Otto Lilienthal’s bamboo-and-cloth gliders in 1895 through wooden frameworks using spruce, aluminum stressed-skin monocoques, and the carbon fiber reinforced polymers that define contemporary airframe construction. The series provides a comprehensive historical framework for understanding why today’s aircraft employ specific material choices, connecting material properties to structural design philosophy and manufacturing constraints that shaped each successive era of powered flight.

Lufthansa Technik and Airbus Extend AeroShark Riblet Film to A330 Wings and Empennage
Lufthansa Technik and Airbus are collaborating to extend shark skin-inspired riblet film technology to the wings, vertical fin, and horizontal stabilizers of the A330ceo, broadening AeroShark application beyond fuselage and nacelle surfaces. The microstructured film mimics shark skin texture, displacing turbulent boundary-layer flow 50 micrometers from the surface to reduce aerodynamic drag during cruise. Combined modifications could cut fuel consumption by more than two percent on in-service A330ceos flying long-haul missions. The collaboration represents a significant expansion of aerodynamic efficiency retrofits for the widebody fleet still in active service worldwide.

IAI Aviation Group Targets Full LEAP Engine Overhaul Capability Before Year-End
Israel Aerospace Industries’ aviation group is targeting full overhaul capability for CFM LEAP engines before year-end 2026, following its introduction of Quick Turn Shop Visit capability for the new-generation powerplant. IAI plans to achieve test cell correlation certification at its Tel Aviv facility, enabling complete engine performance restoration and testing. The company aims to induct 80 to 100 LEAP engines annually, scaling to 250 per year once a planned additional maintenance facility is operational by 2027. Investments include laser cladding and automated grinding equipment to support advanced component repairs for the next-generation fleet.

FTAI Aviation Nearly Doubles CFM56 Module Maintenance Volume in First Quarter
FTAI Aviation serviced 270 CFM56 engine modules in the first quarter of 2026, nearly doubling prior-year volume as its expanding MRO network gains momentum. The increase includes first contributions from FTAI’s new facility in Lisbon, Portugal, while established shops in Miami and Montreal processed more than 200 modules between them. FTAI now holds capability for approximately 70 percent of the CFM56 program and commands roughly 12 percent of the $25 billion annual CFM56 and V2500 maintenance market, targeting 25 percent share. The company has no immediate plans to enter next-generation engine maintenance, citing sustained current-generation demand.

Boeing 777X Change Incorporation on 30-Plus Stored Airframes Will Take Years
Boeing CEO Kelly Ortberg confirmed that incorporating design changes into more than 30 stored 777-9 airframes will take years to complete, with older aircraft requiring the most extensive structural modifications. The fuselages, built to earlier design standards during the prolonged certification flight test program, no longer match the configuration Boeing is now certifying for production. Older airframes need structural-level rework while newer builds require only minor software and systems updates. The final certified configuration, expected in late 2026, will determine the full scope of each aircraft’s modification package, creating a complex engineering challenge for Boeing’s widebody program.
