Company Policy; Procedure
Management email sent to Maintenance Controllers instructing us to NOT follow Company GMM [General Maintenance Manual] procedures; but to follow their email instructions instead.I am not allowed to ask a pilot to do anything that is not in their AFM; no matter what source; be it the MM; FCOM; or systems manufacturer's manuals. How can you tell me I have to follow an email instead of the Company GMM.Stop leading and directing by email. Either publish the directions/processes correctly; or stop the use of that process until it is corrected and published in the proper source document.
