Marine Corps (USMC) Enlisted Job Descriptions

OCCUPATIONAL FIELD 60/61/62, AIRCRAFT MAINTENANCE

The aircraft maintenance OccFlds includes direct and direct support of the total airframes and power plant package of all aviation aircraft weapons systems.

While there is similarity in the skills required to provide this support, the systems being supported are diverse. The following examples are provided: direct support-repair and servicing at the organizational maintenance activity which is normally accomplished on aircraft; e.g., preflight and servicing of aircraft and their systems; indirect support-repair of components at the intermediate maintenance activity which is normally accomplished off aircraft; e.g., hydraulic actuators, servos, and accumulators, aircraft engines, and transmissions.

Marines entering these fields receive MOS 6000, Basic Aircraft Maintenance Marine, and then progress through specific hard skill MOSs.

After completion of formal training, Marines are qualified to maintain airframes and aircraft component. The opportunity to participate in a formal apprenticeship program leading to receipt of a Department of Labor Certification of Apprenticeship Completion may be available in some MOSs within OccFlds 60/61/62; refer to MCO 1550.22 for specific information concerning this program.

As the Marine progresses, repair and administrative requirements for multiple systems take on an equal importance until the Marine is placed in a management/supervisory position.

Billets for both repair and administration are varied and extend from the squadron level to staff positions at the wing, force commander, and Headquarters U.S. Marine Corps level.
