3.7.8.2 Appendix B - contingency material list. A contingency material list shall be developed. It shall be a
tabular listing of parts, similar to figure 2. When developed, there shall be a separate sheet for each unit
subassembly or major subassembly or component. The contingency material list is a guide for material that may be
needed when the unit is overhauled. It shall list the parts, which may require replacement during the overhaul of the
unit. Any part listed in the contingency material list shall be addressed in the appropriate inspection and repair
subsection of the TRS. Those parts whose costs approach or exceed the total cost of the unit shall not be listed.
Parts which rarely require replacement and are not normally replacement parts for unit overhaul shall not be listed.
A MOG, if it exists, may be used to develop Appendix B.
3.7.8.3 MC/OR. A certification document shall state that the overhaul has been properly completed and meets
all the acceptance criteria. It shall also provide a means to collect additional information from the line mechanic
concerning conditions observed prior to, and during, the overhaul. Directions for recording data and distribution of
the report shall be specified in the TRS text. A typical MC/OR is shown in figure 3. At a minimum, MC/ORs shall
conform to the following:
a.
Check-the-box and short fill-in questions shall be used to the greatest degree possible.
b.
A heading identifying the component shall be completed.
c.
Specific questions regarding the "as-found" material condition of the item shall be prepared.
d.
Provision shall be made for the mechanic to supply informal comments and short remarks.
e.
Specific questions or statements regarding the "as overhauled" state of the item shall be prepared.
f.
Provision shall be made for the mechanic to record or highlight any approved or unapproved deviations and
out-of-spec data.
g.
A separate MC/OR shall be prepared for each subassembly and major subassembly component and shall be
included in the appropriate data section in volume 2.
h.
MC/ORs shall be identified in the table of contents, list of effective pages, and TRS text.
3.7.8.4 Appendix C (volume 2) - ETRAR. Required ETRAR information (see figure 4) shall include the
system test step number and the desired response and tolerance limits. Other information may vary according to the
equipment type or user requirements. Separate summary sheets shall be developed for each subassembly and major
subassembly or component as previously specified in the TRS and assigned an appropriate title. Each instruction to
record data in the TRS text shall also be entered in the ETRAR. When possible, a line drawing identifying the
measurement to be taken shall be provided on the same page. Reading specifications or parameters that depart from
original design characteristics shall be highlighted and footnoted with rationale. A space for signatures at specified
data entry and I&V points shall also be provided. The last section of Appendix C for each major subassembly
component and the last section of the total unit shop test and unit FAT shall specify the minimum criteria for
determining whether the Class B overhaul requirements are in accordance with Government testing criteria. No
space for recording data on these pages shall be provided. However, activities shall be directed to submit all local
shipyard test forms with the completed overhaul record (Volume 2 of the TRS).
3.7.8.5 Additional appendices (D and on). When specified by the acquiring activity (see 6.2), the text in the
body of the TRS shall specify any other special requirements covered, with additional appendices.
3.8 Electronic equipment TRS technical content. The sequence of electronic equipment TRS technical data
shall conform to the following:
a.
Front matter (see Appendix A of MIL-DTL-24784).
b.
