scope:

This standard establishes the technical content requirements for the preparation of maintenance instructions for weapon systems and equipment Technical Manuals (TMs) and Depot Maintenance Work Requirements (DMWRs). These requirements are applicable for both paper and digital page-oriented TMs. Electronic delivery of maintenance instructions for TMs is accomplished through the use of the Maintenance Instruction modular Document Type Definition (DTD). The DTD is available in digital format. Refer to MIL-STD-40051 for information on obtaining this DTD. All maintenance requirements necessary to develop Operator (-10), Unit (-20), Aviation Unit Maintenance (AVUM), Direct Support (DS) (-30), Aviation Intermediate Maintenance (AVIM), General Support (GS) (-40), and/or depot level (overhaul) TMs are included.
