MIL-DTL-24784/7C(NAVY)
3.7.1.1 Scope. The scope shall include a brief summary of the purpose, content, and arrangement of the TRS,
including appendices. It shall also state that all commercial and Government activities involved in the overhaul
process must meet all TRS Class B overhaul requirements.
3.7.1.2 Points of contact. This paragraph shall state that the TRS takes precedence over all other technical
documents for overhaul of the commodity. It shall further state that the shop supervisor or design division should be
contacted regarding problems associated with use of the TRS.
3.7.1.3 Overhaul conformance. This paragraph shall state that compliance with the applicable chapters of the
TRS is mandatory and that, upon completion of the overhaul, equipment must meet the stated performance
specifications. This paragraph shall also contain the following information:
a.
Specify that configuration changes are not authorized without Government approval.
b.
Address visual inspection requirements of replacement parts and specify that the TRS does not require
replacement part testing.
c.
State that parts listed in the mandatory overhaul replacement parts list (Appendix A) (see 3.7.8.1) are
included because of high past failure rates and/or cost to repair or replace and that these parts shall be
replaced regardless of condition. Therefore, this material shall be on hand prior to performing a Class B
overhaul in accordance with the TRS.
d.
Specify that the contingency material list (Appendix B) (see 3.7.8.2) contains a list of those parts that may
need to be replaced during the overhaul. The decision to buy these contingency parts shall be made by the
overhauling activity.
e.
Direct the TRS user to record specified readings test results, inspection and examination results, as well as
corrective actions; and forward this data to the TRS maintenance activity.
f.
Specify that data readings are recorded at certain inspection and verification (I&V) (see 6.4.5) points during
the overhaul. An individual shall be chosen to sign off on all mandatory I&V points. The local
overhauling activity may designate additional I&V points if needed.
3.7.1.4 Documentation and references. A tabular listing shall be developed to present all documents,
publications, product engineering drawings and schematics, specifications and standards, engineering change data,
and other reference data used in the development of the TRS and referenced in the text. Applicable documents shall
be listed in the order they are referenced in the text.
3.7.1.5 Unit assembly and subassembly. This paragraph shall identify the repairable items (see 6.4.7) covered
by the TRS. Items shall be identified by nomenclature, model number, allowance parts list (APL), Commercial and
Government Entity (CAGE) code, and manufacturer's part number. These data shall be listed in tabular form. This
paragraph shall also provide a tabular list of the ship or machinery alterations, which have been incorporated into the
TRS and the hull numbers to which they apply. If no ship or machinery alterations have been incorporated into the
TRS, a statement to that effect shall be included.
3.7.1.6 Parts replacement. Subparagraphs in this topic area shall be developed to specify that:
a.
The local manufacture or fabrication of certain parts is strictly forbidden. Because of the critical nature and
stringent manufacturing requirements, the Government has restricted the manufacture of these parts to
qualified sources. A tabular listing of all such parts shall be provided. The list shall contain the restricted
part by name and part number. In addition, these parts shall be highlighted by an appropriate note in
Appendices A or B (see 3.7.8.1 and 3.7.8.2), as applicable. A printout of those parts which have been
restricted may be obtained from the Government activity providing supply support for the commodity.
b.
Parts examined which do not meet acceptance criteria may be repaired [if not on Appendix A (see 3.7.8.1)
or a restricted part] or shall be turned in to the supply system or disposed of using current procedures and
documentation. Local manufacture of non-restricted parts may be accomplished when acquisition is
delayed; however, these parts shall conform to drawing specifications and source inspections.
c.
Shop store items such as gaskets and packing material, locknuts and lock washers, cotter pins, keys, and so
forth, are not listed in the mandatory overhaul replacement parts list or contingency material list but shall
be replaced. This material shall be on hand to accomplish the planned overhaul maintenance.
