MIL-DTL-24784/7C(NAVY)
3.8.4.2 Test data record. The TRS shall require that the results of the test procedure be recorded on the test
data record. The satisfactory operation of the RFI repairable items shall be verified by the depot quality assurance
element personnel.
a.
The data required are the procedural steps, performance requirements, TRS title, TRS number, item
nomenclature, and item part number (see figure 7).
b.
The TRS shall also indicate that the designated depot maintenance activity responsible for the repairable
items repair, shall establish and maintain a file of the completed TRS test data records.
c.
Other instructions as may be determined for the repairable items type shall be specified.
3.8.5 Chapter 5 - overhaul procedure and FAT. This chapter shall contain all procedures, processes, and
methods for the satisfactory accomplishment of all overhaul and repair work (see 6.2). It shall also contain the
instructions required for the accomplishment of the FAT of the repairable items covered by the TRS. Acceptance or
rejection criteria for wear, deterioration, dimensions, electrical parameters, alignments, adjustments, and other
standards of acceptance shall be specified. Additional information may be required to properly accomplish
particularly difficult repair actions.
3.8.5.1 Removal, disassembly, and inspection. Illustrations and step-by-step procedures (see MIL-DTL-24784)
for the removal, disassembly, and inspection of the repairable items shall be developed. Disassembly instructions
shall be limited to areas where the sequence of disassembly is not obvious or where special techniques are required
for access to a part requiring repair. Where examinations, inspections, and tests must be performed during
disassembly, the TRS shall so specify.
3.8.5.1.1 Disassembly illustrations. Illustrations shall show the sequence of disassembly and shall contain part
identification data by item number, noun name, quantity, and reference designation.
3.8.5.1.2 Criteria for suitability of worn-in parts versus new parts. Criteria to determine the suitability of worn
or degraded critical parts for continued use shall be presented. The criteria shall explicitly state those measurable
wear or deterioration limits which, if exceeded, require replacement by new parts. These data shall be briefly
presented, preferably in table format, and shall identify the parts involved, provide the measurable limits, and
specify the required actions. Mandatory replacement items shall be clearly identified and reference made to the
appropriate listing in the TRS Appendix A.
3.8.5.2 Cleaning and inspection. When applicable to the repairable items covered in the TRS, the process and
methods of cleaning and examination to be performed on each disassembled item shall be described. Cleaning and
inspection instructions shall contain the following:
a.
The pre-cleaning examination requirements and the cleaning process to be used for each item requiring
cleaning.
b.
Step-by-step procedures for accomplishing the process (see 3.8.5.1).
c.
Specific identification of cleaning material to be used in the process by their commonly known name and
specification number. These data may be provided in tabular format.
d.
Quantitative instructions for the variables associated with the cleaning process; for example, air pressure,
moisture content, solvent temperature, soak time, ultrasonic frequency, drying time, and temperature.
e.
Procedures for use of any special tools, jigs, or fixtures required during cleaning.
f.
Post-cleaning examination, preservation, and handling instructions.
g.
Cautions, warnings, or dangers to be observed to protect personnel and equipment.
h.
Other data as may be determined appropriate for the repairable items.
3.8.5.3 Reassembly and inspection. Illustrations and all reassembly instructions and examination requirements
for the reassembly of the repairable items shall be developed. The use of any special tools, jigs, fixtures, or test
equipment shall be specified. If reassembly is the reverse of disassembly, a statement to that effect shall satisfy this
requirement. The instructions or procedures shall indicate the following:
a.
Use of corrosion-preventive compounds, paints, or other materials. Gaskets or sealing compound materials
shall be specified by nomenclature, trade name, specification number, and NSN.
