All services · FAA Table A-4
All 46 Marine Corps MOS entries from Appendix A of AC 65-30B Change 1, reproduced in full. 15 map to both ratings outright.
What the table shows
Forty-six codes across four blocks: intermediate-level maintenance in the 60XX range, rotary wing and tiltrotor in 61XX, fixed wing in 62XX, and avionics in 63XX.
The pattern is consistent and worth knowing before you look yourself up. Codes titled simply “Mechanic” or “Crew Chief” map to both ratings. Codes titled “A/F Mechanic” map to Airframe. Codes titled “P/P Mechanic” map to Powerplant.
If you were avionics: every 63XX code maps to Airframe only. If you want Powerplant as well, you need documented engine-side work — from a second MOS, a collateral billet, or civilian experience layered on top. Plan for that early, because it changes whether you are chasing 18 months or 30.

Both = “Airframe and Powerplant.” Note 2: “Codes listed in the 'Previous Code' column are no longer active but remain listed, since experience does not expire.”
Your old code still counts
The AC states it directly: “Aviation maintenance experience does not expire; therefore, the codes in the 'Previous Codes' column are still valid for persons wishing to credit their military aviation maintenance experience toward meeting the requirements of an FAA Mechanic Certificate.”
There is no cut-off date and no requirement that your service be recent. If you got out in 1994, your code is as valid today as it was then.
Where your evidence lives
Start with your OMPF and the qualification records that establish task authority — CDI, CDQAR, QAR and plane captain designations.
Marine Corps training appears on the Joint Services Transcript.
A correction, because this circulates in veteran forums: NAVMC 11432 is not a maintenance or training record. It is the Marine Corps Martial Arts Program Instructor’s Course Record. If someone tells you to request it for this purpose, they are wrong.
Everyone needs a DD Form 214, Member-4 or Service-2 — not Member-1, which omits fields you need. milConnect is fastest if your separation date qualifies; eVetRecs and the SF-180 are the fallbacks.
The part the table does not tell you
Finding yourself in the table above establishes which rating your experience points at. It does not establish how much creditable experience you have — and that is the number that decides whether you can apply at all.
Training time does not count: not boot camp, not your MOS or tech school, not the follow-on pipeline. For many maintainers that is six to twelve months off the top. Purely supervisory and inspection time is at risk too, which hits the most senior people hardest.
Work out where you actually stand — it takes about two minutes and it is the thing to do before you request a single record.
