Our high-quality work, delivered on time and on budget provides you improved cost-effectiveness of your engineering and technical resources, without the need for additional head count. By using our services, you gain access to an expanded talent pool providing a wide variety of disciplines and level of expertise that may not be available in-house.

By supplementing your engineering and maintenance resources, our seamless integration with your processes and procedures improves your cycle time while reducing project backlogs. All of our work is performed in compliance with your established policies, procedures and paperwork requirements.

We provide “total care” for your engineering service needs, handling the entire value chain including initial feasibility studies, cost and benefit analysis, engineering design, substantiation certification, fabrication and installation documentation and modification kits. Our engineering services are part of AAR’s 1MRO service offering, providing customers with a broad range of capabilities and a consistent, seamless approach across facilities.

We know aviation. With more than 60 years of direct airline and MRO experience, we understand the needs, priorities and operational challenges of your business and are able to rapidly offer solutions to support your most challenging engineering requirements.

Program Integration

We provide comprehensive oversight of your program, from new product feasibility studies and cost analysis to supplier management (both SFE and BFE) and on-site installation support, with an underlying emphasis on flexibility and accountability.

Engineering & Design

We develop innovative engineering and installation solutions for aircraft interior reconfigurations, structural and systems modifications, and avionics upgrades. We undertake concept and detailed design, stress analysis of metal and composite structures, and mechanical and electrical systems integration using advanced CAD/CAE systems.

Program Management

We utilize a program management methodology across all programs based on comprehensive risk management techniques. Major elements of this approach include schedule/milestone management, budget, resources, risk analysis and mitigation, supplier management, communication, and metrics/scorecards.


Leveraging our abundant manufacturing resources and strategic partnerships, we provide detailed part design and fabrication, modification kit assembly, and the requisite FAA or foreign regulatory approvals.


Through our expertise in this area, we assist customers in obtaining all required regulatory authority approvals for modifications (e.g., FAA Supplemental Type Certification [STC]).

Crew Rest

We provide a certified solution for commercial aircraft operators to use widebody cargo space to meet the FAA’s requirement for environmentally controlled areas where crews can lie down and rest during long-haul flights. Our solution takes advantage of the quiet areas below the main deck to provide crews a place to rest in comfort, convenience and safety, away from the noisy galleys and lavatories of the passenger cabin. This placement also reserves space on the main deck for additional seating and increased revenue.

Life Raft Stowage

We offer a life raft storage solution, designed for and certified on Boeing 737NG aircraft. Our innovative storage compartments utilize the aircraft’s ceiling above the aisle, rather than highly coveted overhead bins, opening up carry-on baggage space to passengers.
