MIL-DTL-81928C(AS)
3.1.9.2 Maintenance level coverage. When two or more levels of maintenance coverage are
presented in a single manual or in a set of manuals, the coverage shall be as directed by the
requiring activity. Maintenance level coverage may be presented as follows:
a. When the aircraft system or equipment is provisioned for organizational level repair;
(1) The manual shall contain complete organizational maintenance procedures without
reference to the intermediate or depot maintenance manuals for continuation or
completion of the procedure.
(2) Organizational level authorized minor repair actions that do not affect the integrity of
the item should also be included, e.g.,. fuse, lamp, or knob replacement. Minor repair
actions of this type are not considered "complete" repair actions and as such do not
justify assignment of a Source, Maintenance and Reliability (SM&R) code (see
NAVAIRINST 4423.11). Other references required shall be prepared in accordance
with MIL-DTL-81927.
b. When repair actions (tasks) for the aircraft are authorized for more than one level of
maintenance, e.g., aircraft structural repair, nondestructive inspection, etc.;
(1) The differences in maintenance level coverage shall be noted in the text or by
separate WP.
(2) Normally this option will be exercised when either one or both levels of maintenance
covered are limited in scope.
(3) When a few items of support equipment are not authorized for the organizational
and/or intermediate level maintenance, the restriction shall be annotated in the
"Support Equipment Required" listing.
(4) When the basic support equipment is not approved at all levels, the coverage shall not
be contained in the same manual.
3.1.10 Task development. The task development phase of the technical manual preparation
is critical because it will establish the arrangement and organization of the technical information
and together with the task analysis will establish the depth and scope of the coverage. Based on
the requirements identified by the task analysis, all tasks for end item operation (if required) and
the testing, troubleshooting, and maintenance coverage requirements at the appropriate
maintenance level(s) can be established. Once the basic operation and maintenance tasks are
established, the depth and scope of the supporting data can be identified, e.g., description,
