Army Maintenance Status Codes: A Complete List

Using codes is a huge part of Army maintenance staff. Instead of writing out everything, there is a easier system by using a code system for paperwork and computer systems that will make sure the equipment is repaired properly and delivered back to the right personnel.

In today’s post, I am going to provide Army Maintenance Status Codes. You can copy and print these, and use them as “cheat sheets.” Now lets go through this long list as Army Maintenance Status Codes:

Final Thoughts

These are the most used Army Maintenance Status Codes. Feel free to print off these and use them as a cheat sheet. I truly doubt there is any Maintenance Technician that can remember all of these codes.

If you need some other codes, I recommend you visit and read the Army Maintenance Management System (TAMMS) Users Manual (Army Pamphlet 750-8). Everything you need is printed there.

If you have any comments, tips or questions, you can post them below. Thank you.

Sincerely,
