437th Maintenance Squadron

Feb. 13, 2013

The 437th Maintenance Squadron (MXS) consist of seven flights which include 14 unique sections. Our no-fail mission is about providing safe, reliable aircraft and delivering uncompromised combat capability to the war fighter--absolutely anywhere in the world. MXS is composed of over 500 combat-ready maintainers and support personnel, comprised of Active Duty, Civilian, and Air Reserve Technician components. They inspect service, maintain, and support assigned C-17 aircraft and associated equipment at Joint Base Charleston. These maintainers enable aircraft to perform global airlift missions ranging from combat support operations and humanitarian relief to aeromedical evacuations. The squadron is also responsible for maintenance around the world through AEF and short-notice deployments in support of any mission, anywhere.

The 437th Maintenance Squadron is responsible for the maintenance of 51 assigned C-17A aircraft worth more than $10 billion dollars. MXS primarily performs back shop and flightline support to include structural, avionic, hydraulic, electrical, environmental, survival, and fuels maintenance. Additionally, we conduct scheduled Home Station Check (HSC) inspections, Non-Destructive Inspections (NDI), and Aerospace Ground Equipment (AGE) support. Our world-class Precision Measurement Equipment Laboratory supports Test Measurement & Diagnostic Equipment maintenance for the entire region. Furthermore, our maintenance flight produces time critical wheel and tire assemblies for locations around the world.

With each and every day that passes, the "Mavericks" continue to improve processes, streamline procedures, and exude the squadron's slogan of "Only the Best!" That slogan, and its underlying themes, run rampant throughout the squadron and are embraced by the outstanding personnel assigned. Our team's flawless flightline and back shop support spurred a record 13,916 global mobility missions supporting 51,606 flying hours. Amazingly, Team Charleston boasted a 95% worldwide maintenance departure reliability-rate recognized as the best in AMC strategic airlift. Amazingly we achieved these phenomenal successes despite flying the oldest C-17s in the fleet. We did it through teamwork and by reaching for the STARS: Safety, Training, Attitude, Readiness, and Standards.

Our mission statement, "To provide unmatched on and off-equipment maintenance and the highest caliber personnel supporting the Global Reach mission," captures the spirit of what we do, the diverse support we provide, and reflects the enormous scope of operations these squadrons support. It recognizes that our efforts are not limited to the 437th/315th Airlift Wings or even to Air Mobility Command (AMC), but around the globe supporting the Air Force's Global Reach doctrine and mission.

Emblem (Approved on 27 September 1966)

On a background of the day and night sky, indicating round-the-clock operations, a hand holding an aircraft appears as a symbol of the squadron's mission of support in keeping the aircraft flying. The triangle is an ancient Egyptian symbol, its three points representing the sun, moon, and stars. It is used to signify the heavens, from where our help comes. The motto expresses the spirit of our personnel. The emblem bears the Air Force colors, ultramarine blue and golden yellow.

Motto: "AD EXACTA CAPACES" (Can Do) [literally translated "To Exact Standards"]
