Middle River Aerostructure Systems is building up its maintenance, repair and overhaul (MRO) capabilities, responding to the company’s expanded jet engine nacelle programs and composite materials expertise.
MRAS applies the skills it has perfected as an OEM (original equipment manufacturer) for nacelles and their thrust reversers, covering such jet engines as the CFM International LEAP-1A and LEAP-1C; as well as GE Aviation’s GEnx-2B, Passport and CF6. MRAS has industrial resources and demonstrated proficiency in both composite and metal bonding.
Among the activities authorized by the company’s FAA/EASA Part 145 Repair Station Certificate are the maintenance, repair and overhaul of nacelle systems for the CFM International CFM56-5B, CFM56-7B and International Aero Engines V2500, which power two widely used single-aisle category jetliners: Boeing’s 737NG and the Airbus A320 family.

engine nacelle systems
For the CFM56-5B, CFM56-7B and V2500, MRAS’ maintenance, repair and overhaul capabilities encompass the full nacelle system: from inlet and fan cowl to the thrust reverser. As part of its MRO investment, MRAS has sets of CFM56-7B and V2500 nacelle components for exchange – enabling rapid-reaction swap-out.
MRAS’ location in the Baltimore, Maryland area positions the company at the heart of the U.S. East Coast air corridor served by large fleets of Boeing 737NGs, and strategically places it to support airlines operating A320s across North America.
Also included in the MRAS Repair Station Certificate’s MRO authority is the composite thrust reverser transcowl it produces for Airbus’ A320neo family – one of the world’s best-selling single-aisle jetliner product lines.
MRAS is developing a dedicated, 60,000-square-foot MRO workshop at its Middle River, Maryland headquarters – which is backed by a multi-million-dollar investment in tooling, machinery and systems.
Beginning with a floor-to-ceiling refurbishment of the dedicated MRO shop area, the company is building out the MRO operation with acquisition of such equipment as a hydraulic test stand for thrust reverser deployment functional testing, paint and power wash booths, component lift stands and a vertical carousel for parts.
MRAS completes PIP (Performance Improvement Package) work in the repair station on the GE Aviation GEnx-1B engines that equip Boeing 787s. This benefits from its specialization in composites and involves the grinding back of composite material around the fan case interior, followed by the case’s rebuild and delivery.
