3.7.4.5 Inspection, data collection, and corrective actions. Procedures, special instructions, examination, and
technical information (including supplementary illustrations and tabular lists) required to perform effective
inspection and repair of the repairable items covered in the TRS shall be identified (see 6.2). The actions to be
performed shall ensure that the repairable items meet or exceed the specified performance requirements of the final
acceptance test (FAT) (see 6.4.4) and satisfy all quality assurance inspection requirements.
3.7.4.5.1 Fault identification. Detailed step-by-step procedures for identifying problems shall be developed.
3.7.4.5.2 Corrective action. Detailed step-by-step procedures for corrective actions, including the repair and
replacement of defective, damaged, or deteriorated parts, shall be developed.
3.7.4.5.3 I&V. The I&V points shall be noted in the TRS left-hand margin by I or V, both in the text and
Appendix C. The I&V points shall be determined by using the best engineering judgment. All data to be collected
shall be specified in the text. The requirement to sign all I&V points shall be included in the front matter of volumes
1 and 2 of the TRS. Signature blocks shall be provided as appropriate in the ETRAR (see 3.7.8.4).
3.7.4.5.4 Alignment and adjustment procedures. Detailed procedures shall be identified or developed for
sophisticated mechanical and electrical alignments and adjustments. Procedures shall describe the methods used and
special tools and equipment required to achieve the setting and positioning of adjustments and controls, and
mechanical, gearing, and linkage alignments within the repairable item.
3.7.4.6 Reassembly. Illustrations, reassembly instructions, and examination requirements for the reassembly of
the repairable items shall be developed as required. The use of any special tools, jigs, fixtures, or test equipment
shall be specified. Where sequence of reassembly is obvious, it is sufficient to state: "Reassemble by installing parts
in accordance with the reassembly sequence numbers". Additional instructions, cautions, warnings, and dangers
shall be specified in sequence within a reassembly instruction when required. Figures prepared to support
disassembly instructions may be repeated; however, sequence numbers shall be changed to reflect proper numerical
order for reassembly. The instructions or procedures shall indicate the following:
a.
The use of corrosion-preventive compounds, paints, or other materials and the use of gaskets or sealing
compound materials shall be specified by nomenclature, trade name, specification number, and national
stock number (NSN). Non-NSN consumables and materials shall be avoided whenever possible.
b.
Identification of all points requiring lubrication, the kind of lubricants required, and the method of
application. Lubricants to be used shall be those specified in the standard lubricants lists. A NSN shall be
listed if available. Additional information regarding lubrication can be found in MIL-HDBK-267.
c.
Any special instructions for installing fasteners, safety wiring, cotter pins, and other locking devices.
d.
Special instructions for aligning, adjusting, and measuring tolerances, clearances, end play, backlash, and
tolerances between gears and linkage alignment data.
e.
Identification of critical examinations and tests during reassembly and, if required, provisions for data
collection.
f.
Reference to tables, appendices, or illustrations as applicable.
g.
Other data as may be determined appropriate for the repairable items type.
3.7.4.7 Acceptance test. Acceptance testing (see 6.4.1) shall be specified for each individual component, if
needed, and for the system as a whole (see 6.2). The section shall specify that:
a.
After completing all repair or overhaul actions and when the repairable item is considered ready for final
examination, the item shall be inspected for proper identification and tested to verify satisfactory
performance.
b.
The acceptance test shall be accomplished in accordance with the established performance requirements.
Reference shall be made to pertinent data contained elsewhere in the TRS.
c.
Specified data collection requirements for the item shall be included in the TRS ETRAR (see 3.7.8.4).
3.7.5 Chapter n + 1 (or as applicable) - unit assembly. This chapter shall specify all criteria addressed in
Chapter 3 as applicable to unit reassembly. The following items shall be covered:
