Aerospace Maintenance Solutions Earns New AS9100D Certification, Expands Service Offerings to Military Aircraft End Users

[Solon, OH] – Aerospace Maintenance Solutions (AMS) is proud to announce its recent achievement of the AS9100D certification. With this new certification, AMS can now offer a wider range of service options to military aircraft end users, particularly in the area of legacy aircraft components.


One of the key capabilities enabled by AMS’s AS9100D certification is its expertise in reverse engineering. By employing this process, AMS can address the challenges posed by Diminishing Manufacturing Sources and Material Shortages (DMSMS) and provide effective solutions to military aircraft operators.


AMS excels in supporting military aircraft components afflicted by DMSMS due to various reasons, including the discontinuation of critical parts by original equipment manufacturers (OEMs), unavailability of small parts and subassemblies for legacy components, and neglect of lesser-valued parts by large corporations after acquiring smaller companies. When faced with non-functioning units that cannot be repaired or sourced from the open market, AMS utilizes reverse engineering techniques to duplicate and manufacture these components.


Reverse engineering involves replicating an item’s fit, form, function, and dimensions based on proven flightworthy units. At AMS, this process is conducted in adherence to AS Quality practices, utilizing a comprehensive library of authenticated manuals, technical documents, and drawings, as well as following the guidelines set by the US Department of Defense for reverse engineering.


By offering reverse engineering capabilities, AMS significantly reduces procurement costs for spare and replacement parts, especially for components with limited or no existing manufacturers. This cost reduction aligns with the increased focus on competitive procurement within defense budgets for the U.S. Air Force, Army, Marines, Navy, and Homeland Security. To foster competition and minimize restrictions, the U.S. Congress and the Department of Defense have implemented the Defense Acquisition Regulation Supplement No. 6 (DAR-S6), known as the DOD Replenishment Parts Breakout Program.


With the AS9100D certification, AMS is well-equipped to ensure the mission readiness and ongoing maintenance support for a wide range of military aircraft.

Senator Dolan acknowledges AMS contributions to Ohio economy

Ohio Senator Matt Dolan has recognized Aerospace Maintenance Solutions (AMS) for its economic impact to the State of Ohio; the birthplace of Aviation. All of AMS revenue comes from outside the State of Ohio, much of it from outside the U.S. However, the Solon-based company is redistributing global currencies to support local Ohio economies.

In 2019, the company spent several million dollars renovating the new facility using all Ohio contractors. AMS spends millions of dollars yearly on salaries and benefits for their employees, all located in Ohio. AMS revenue also supports an important supply chain consisting of Ohio companies: software developers, component and material suppliers needed to support repairs of military aircraft components, calibration services for test equipment, soldering training services, and FAA and AS9110 training.

From a single location in Ohio, AMS provides critical repair and overhaul services needed for U.S. military aircraft (e.g., F-16, UH-60, C-130) to protect the U.S. homeland. AMS effectively lowers U.S. military costs with process innovations, which also enables mission readiness by minimizing maintenance delays. Ohio military bases supported by AMS include Wright-Patterson Air Force Base, Youngstown Air Reserve Station, U.S. Coast Guard Great Lake Station, U.S. Army Reserve, Toledo Air National Guard, and Mansfield Air Nation Guard.

AMS services also support the U.S. Border Patrol and the Department of Homeland Security aircraft as well as aircraft used by police, fire-fighters, DEA, search-and-rescue, EMS, and other public safety operations across the U.S.

AMS supports Ohio Governor Advisor Joe Zeis in his mission to “Preserve and expand Ohio’s Aerospace and Defense Industry. . . and Maintain and grow the workforce.”

As part of the U.S. Department of Defense’s Industrial Base, AMS was identified as part of the U.S. Critical Infrastructure Sector by the Undersecretary of Defense and the Department of Homeland Security during the COVID-19 pandemic. Beginning on March 19, AMS employees in Ohio have maintained normal work schedules per the Undersecretary’s guidelines. Since then, AMS has not laid off, furloughed, or otherwise reduced its workforce. It is one of a very few aerospace companies in Ohio actively seeking to increase the number of overall employees during 2020 by hiring additional personnel.

AMS welcomes DCMA representative to new on-site office

Solon, Ohio – Starting in July of 2020, Aerospace Maintenance Solutions, LLC (AMS) will welcome a DCMA representative to an onsite office at AMS headquarters in Solon, Ohio.


DCMA is an agency of the U.S. federal government reporting to the Under Secretary of Defense for Acquisition and Sustainment. It is responsible for administering contracts for the Department of Defense and other authorized federal agencies.


DCMA oversight is a “higher level contract requirement” for contracts AMS has with the United States (U.S.) military and prime military aircraft OEMs (e.g., Lockheed Martin). AMS is an FAA Part 145 repair station with an AS9110 Quality system. The DCMA (Defense Contract Management Agency) supports the culture of Quality at AMS.


The new on-site office arrangement makes sense for both DCMA and AMS because the DCMA representative is regularly at the facility now to inspect AMS maintenance, repair, and overhaul work completed for the U.S. Air Force, U.S. Navy, U.S. Army, U.S. Department of Homeland Security, and military aircraft OEMs. The representative will also continue inspection duties with other companies in the Cleveland area.


DCMA oversight also benefits foreign military allies by upholding the highest standards of quality, workmanship, and reliability.
