Airbus and Pratt & Whitney Say A220 GTF Engine Crisis Is Nearly Over
Airbus and Pratt & Whitney say the multi-year GTF engine crisis grounding Airbus A220s is nearly resolved. Only 2–3% of the A220 fleet remains grounded due to GTF issues, down sharply from prior peak levels. No A220s are expected to remain grounded by year-end as P&W accelerates replacement engine deliveries and inspection cadence. The A220 Stretch variant—now in active development—will be powered exclusively by the GTF, signaling restored confidence in the powerplant. Airbus confirmed several early-production A220s were scrapped to harvest serviceable engines for the active fleet, a measure of how acute the parts shortage became at the crisis peak.

JetZero Revises Z4 Blended-Wing-Body Design With V-Tails and Winglets
JetZero has revised the aerodynamic configuration of its Z4 blended-wing-body demonstrator, replacing wingtip rudders with V-tail surfaces and winglets. The V-tails provide noise shielding for rear-mounted engines and improve pitch-and-yaw trim authority. Engine mounting on the aft fuselage was also repositioned. The updated demonstrator targets first flight in late 2027. JetZero’s Z4 commercial design aims for 250 seats, a 200-foot wingspan, Mach 0.8 cruise, 5,000-nautical-mile range, and 30–50% better fuel burn than a Boeing 767. The configuration change reflects aerodynamic refinement as the company prepares for full-scale testing of the novel airframe concept.

Boeing Opens Fourth 737 MAX Assembly Line at Everett to Drive Production Ramp
Boeing has opened its fourth 737 MAX assembly line—dubbed North Line—at its Everett, Washington campus, mirroring the production layout at the primary Renton facility. The new line will initially build MAX 8 and MAX 9 variants before adding MAX 10 capability. Boeing is ramping production from 42 jets per month toward its 47-per-month target, though North Line will not support rates above 47 before early 2027. The Everett expansion is part of Boeing’s effort to recover delivery momentum after years of quality and production setbacks. The line began moving aircraft this week as Boeing works to rebuild confidence with airline customers.
Duncan Aviation Opens Expanded Turbine Engine Overhaul Facility in Lincoln
Duncan Aviation has opened an expanded turbine engine overhaul facility at its Lincoln, Nebraska headquarters, adding significant heavy-maintenance throughput. The enlarged shop features 12 dedicated maintenance bays, a new engine test cell, a control room, and a parts inventory warehouse. Duncan has been designated a Pratt & Whitney Designated Overhaul Facility for PW300 and PW500 series turbofans, which power a range of business jets. The expansion addresses growing demand from global operators and positions Duncan as a larger presence in MRO services for business aviation powerplants. Disassembly, inspection, repair, and reassembly work will all be performed on-site at the facility.

Airbus Sets Informal Target of 900 Deliveries in 2026 After Best June Since 2019
Airbus is targeting more than 900 aircraft deliveries in 2026—well above its official guidance of 870—after delivering 89 jets in June and achieving its best first half since 2019. The manufacturer handed over 351 aircraft in the first six months of 2026, up 15% from the same period last year. The informal stretch target reflects improving production momentum as China backlog deliveries clear and Pratt & Whitney GTF-related groundings ease. Airbus expects roughly 80 handovers in July. Supply chain disruptions have not been fully resolved, and leadership is managing expectations around the stretch goal. Official full-year guidance remains 870 aircraft.
Rolls-Royce Says Trent 1000 XE Upgrades Restore Parity With GEnx, Boosting 787 Sales Prospects
Rolls-Royce says durability enhancements to its Trent 1000 XE engine have returned the Boeing 787 powerplant to competitive parity with the rival GE Aerospace GEnx, and the manufacturer is increasingly confident of winning a major new order. The XE upgrade delivers improvements in two phases: the first step doubles time-on-wing; a second phase adds another 30%, recently certified and now rolling into the in-service fleet. More than one-third of in-service Trent 1000 engines have been upgraded, with 100% conversion targeted by end-2027. LATAM Airlines recently selected the Trent 1000 XE for three 787s. Rolls-Royce aims to return to a 40–60% market share on the 787 platform.

Russia Studies Retrofitting Superjet 100 Fleet With Domestic PD-8 Engines After Certification
Russian aviation authorities and manufacturers are studying whether Yakovlev Superjet 100 jets can be re-engined with the newly certified Aviadvigatel PD-8 turbofan. The PD-8 was certified by Rosaviatsia in June 2026 for the new-build import-substituted SJ-100 variant, but retrofitting original Superjets—which use Franco-Russian PowerJet SaM146 engines—requires a separate modification certification effort. United Aircraft estimates approximately 50 jets, roughly one-third of the active fleet, could be re-engined at a total cost of around Rb115 billion ($1.5 billion). Industry minister Anton Alikhanov said a viable financial model must first be developed, with early engine replacements tentatively planned for late 2029. Re-engining is considered more viable for younger airframes.
