U.S. Air Force |
| Following are the updated, new, and the older MOS codes for the U.S. Air Force. Use the new codes for active duty time after January 1990. The older codes are still valid for persons wishing to credit their military aviation maintenance experience toward meeting the requirements of the FAA airframe and powerplant mechanic certificate. |
| NOTE: Some AFSC may have an alphabetical suffix, known as "Shredout." The shredout identifies specialization in a specific aircraft or system. The shredout has no bearing toward creditable experience. |
