Narrative:

I instructed amt to relamp MCP and acp test 4 using mcdp per MM22-11-02. I learned later that a different maintenance manual requires a CAT III check if replacing a command switch. A CAT III check was not accomplished. Add a note in the maintenance manual 22-11-02 stating that a command switch requires a CAT III check.
