adjust and align the equipment; remove, repair, rein- stall, 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.
3.6.7.1 Introduction. The introduction shall contain an explanation of the purpose, scope, and
arrangement of the corrective maintenance data.
3.6.7.2 Adjustments and alignments. This subsection shall contain all information and
