troubleshooting diagrams shall be provided that consist of signal flow diagrams, piping diagrams,
control diagrams, power distribution diagrams, logic diagrams, maintenance schematic diagrams,
and dependency diagrams, as required.
3.6.3.5.2.7 Integrated circuitry packages and nonrepairable assemblies. When integrated circuit
packaging techniques, such as Dual In-Line packages, are utilized, the level of detail on the logic
diagrams may be restricted to that necessary to isolate problems to either a specific integrated
circuit package or if the maintenance concept so dictates, to a specific nonrepairable assembly,
providing there is sufficient detail to understand the process of troubleshooting.
3.6.3.5.2.8 Assemblies and subassemblies, modules, standard electronic modules, designated
nonrepairable.
Logic diagrams, functional information, hardware and test data shall be supplied to the extent
required to understand the operation of the equipment, concept of troubleshooting, and to serve
the basis for affecting a critical repair.
3.6.3.5.2.9 Flow charts. When specified in the TMCR (see 6.2), flow charts for digital devices
shall be provided to support the explanation of machine instructions and test programs, and shall
conform to ISO 6829.
3.6.3.5.2.10 Coding instruction sheets. Coding instruction sheets shall be provided for all
programs. The listing shall contain all coding and address data as well as an adequate notes
section to ensure understanding (see figure 14-3).
3.6.3.5.2.11 Test programs. Test programs with coding instruction sheets shall be developed
and included to support troubleshooting procedures.
3.6.3.5.2.12 Troubleshooting dependency diagrams. Unless otherwise specified in the TMCR
(see 6.2,) one of the following types of troubleshooting diagrams shall be provided to augment the
troubleshooting procedures. Supporting information required to explain the use of the diagrams
shall be provided in the test or general notes.
a. Fault logic diagrams (see MIL-DTL-24784).
b. Troubleshooting-maintenance dependency-matrix chart (see MIL-DTL-24784).
3.6.3.6 Chapter 6, Corrective maintenance. This chapter shall contain instructions required to
adjust and align the equipment, remove, clean, inspect, repair, reinstall, and align all repairable
parts, modules, subassemblies, and assemblies. The instructions shall identify the action to be
accomplished; safety precautions to be observed; tools, parts, materials, and test equipment
required; preliminary control settings; test equipment setup instructions; and step-by-step
instructions, with supporting illustrations, to accomplish the maintenance task. Corrective
maintenance instructions shall be provided for all items designated repairable irrespective of the
maintenance concept unless this information is included in another technical manual and can be
referenced.
