GE XA102 Clears Critical Design Review for NGAP Hardware Build
The GE Aerospace XA102 adaptive-cycle engine has cleared a critical design review, authorising the program to proceed to full-scale hardware fabrication under the Next Generation Adaptive Propulsion initiative. The review confirmed the XA102 meets Air Force specifications for sixth-generation fighter propulsion, covering fuel consumption targets, thrust class, and thermal management demands of platforms carrying directed energy systems. GE’s variable-cycle design switches between high-efficiency cruise and maximum-combat thrust modes in flight. NGAP maintains parallel competing contracts with both GE and Pratt & Whitney, targeting propulsion readiness to support the Collaborative Combat Aircraft programme and next-generation crewed air-dominance fighters.

P&W XA101 Advances Alongside GE in NGAP Sixth-Generation Engine Race
Pratt & Whitney has disclosed fresh progress on its XA101 adaptive-cycle engine as both American engine makers reach a critical juncture in the sixth-generation fighter propulsion competition. The XA101 advances in parallel with GE Aerospace’s competing XA102, with the Air Force overseeing independent development ahead of a competitive down-select later this decade. Both engines employ three-stream variable-cycle architecture enabling pilots to shift between economy-cruise and maximum-combat modes in flight. The designs must also deliver substantially greater electrical power and cooling capacity to support directed energy weapons, advanced avionics, and high-power sensor arrays on next-generation combat platforms.

Rolls-Royce Completes Full Hydrogen Flight-Cycle Ground Tests on Pearl 15 Demonstrator
Rolls-Royce has completed full ground test runs of a hydrogen-combustion demonstrator based on the Pearl 15 business jet powerplant, concluding a four-year research programme with EasyJet, Tata Consultancy Services, and the UK Health and Safety Executive. Tests at NASA’s Stennis Space Center took the GH2-designated engine through a complete simulated flight cycle, including taxi, take-off thrust, cruise, reverse thrust, and shutdown on green hydrogen. Rolls-Royce says the campaign validates hydrogen combustion in large aero engines and advances understanding of combustor materials, cryogenic fuel systems, and future certification pathways. The company continues assessing hydrogen alongside sustainable aviation fuel as long-term decarbonisation options.

MTU and MLS Invest in AI Engine Platform to Drive MRO Digitalisation
MTU Maintenance and partner MLS are deepening their digital transformation with a shared investment in an artificial intelligence-driven engine maintenance platform designed to streamline workflows and cut turnaround times across their commercial turbofan shops. The initiative integrates machine-learning tools into shop floor operations, applying predictive analytics to component health monitoring, repair planning, and capacity scheduling. MTU says the platform will improve data interoperability across both facilities, lifting first-time fix rates and reducing unscheduled removals. The move reflects industry pressure on engine shops from technician shortages, record shop visit volumes, and escalating overhaul costs across CFM56, LEAP, and V2500 engine programmes.

DAS Aviation Adds Landing Gear Repair and Overhaul to MRO Portfolio
DAS Aviation has expanded its maintenance portfolio to include landing gear repair, overhaul, and exchange services for business and regional aircraft, eliminating the need to farm out specialised gear work to third-party shops. The capability covers a range of airframes under FAA-approved repair station authorisations. DAS says the expansion responds to customer demand for integrated maintenance solutions as operators seek to consolidate vendor relationships and reduce aircraft-on-ground time. Landing gear overhaul is one of the more technically demanding maintenance disciplines, requiring specialised tooling, hydraulic expertise, and structural inspection capability. The move broadens DAS’s one-stop offering alongside its existing powerplant and airframe operations.

FedEx MD-11F Returns to Service After FAA Clears Boeing Pylon Bearing Fix
FedEx has returned two MD-11F freighters to revenue service following FAA approval of a Boeing-developed structural modification addressing engine pylon mount bearing failure. The fix requires a new bearing in the aft mount of each wing pylon, with mandatory inspections at defined intervals. The fleet was grounded fleet-wide six months ago after a fatal UPS aircraft accident in November 2025, in which investigators identified fatigue cracking in pylon mount components as a primary causal factor. Aircraft N621FE and N521FE completed Boeing-approved maintenance actions and test flights, with the first revenue mission operating Memphis to Miami on 10 May.

MHI and IHI Post Record Results as Japanese Aerospace Rides Defence and MRO Surge
Mitsubishi Heavy Industries and IHI reported sharply higher revenues for the financial year ended 31 March, driven by surging defence procurement and a recovery in commercial aviation component and engine work. MHI’s Aircraft, Defence and Space division saw revenues climb 35 percent to 1.4 trillion yen, with its commercial segment — producing fuselage sections and composite aerostructures for Airbus and Boeing — rising 23 percent. IHI’s aero engine revenues grew on strong demand for spare engine parts amid the global MRO capacity crunch. Both companies flagged continued capital investment in advanced manufacturing and engine overhaul capacity to meet forecast demand growth through the decade.
