(6) Local manufacturing and assembly instructions.
(7) SE maintenance instructions, when requested.
(8) General maintenance procedures, when applicable to multiple WPs.
(9) Servicing instructions.
3.1.6.1.6 Combined Operation and Maintenance Instructions. Combined Operation and
Maintenance Instructions shall be developed when the operation and maintenance is performed by
the same personnel. Combined manuals shall provide coverage for all applicable functional
elements listed in 3.1.1.5.
3.1.6.2 Layout and arrangement of maintenance information. Manuals shall be prepared as
Operation Instructions and/or Maintenance Instructions with IPBs. The criteria for determining
technical manual requirements shall be based on the approved Maintenance Plan (MP) or the
Level of Repair Analysis (LORA) . The analysis of coverage requirements and related task
analysis (see NAVAIR 00-25-700) shall determine the depth of coverage, its complexity,
information volume (bulk) and environmental usability. The development of the Numerical Index
of Part Numbers, Numerical Index of Reference Designations, and the technical content of the
IPB shall be in accordance with MIL-DTL-81927. The development of other technical content
shall be as specified herein.
3.1.6.2.1 Repairable assembly maintenance WPs. When the LORA/MP directs, WPs shall be
created to provide coverage for the repairable (at manual's maintenance level) assemblies that are
contained in the equipment. Repairable assembly/subassembly WPs shall contain principles of
operation, testing and troubleshooting, and maintenance instructions with IPB to the bit/piece
component. Depending on testing method, the internal circuits, their relationship to each other,
input and output signals, waveforms, and time-phase relationship of waveforms shall be included.
A separate WP shall be created to support each repairable assembly/subassembly. When the task
analysis requires, selected coverage may be located, as separate coverage, within the WP for the
next higher assembly (see Task Analysis in NAVAIR 00-25-700).
3.1.7 Multimanual coverage. (See "Multivolume and Multimanual Sets" in MIL-DTL-
81927.) The coverage may be provided as a combined manual or divided into a set of manuals.
This division may be required for reasons of data element usability, or if the anticipated page
count of the resultant manual requires such a division.
3.1.8 Multilevel maintenance coverage. More than one level of maintenance may be
addressed in a manual or a set of manuals. Manual division shall be by subject matter or levels of
