CHAPTER 4<br />

COMPOSITE AND NON-METALLIC MATERIAL<br />

DEGRADATION AND REPAIR<br />

4.1 PURPOSE.<br />

The information contained in this Chapter is intended to provide<br />

guidance and references for maintenance personnel to<br />

test, inspect, and/or repair damaged/degraded non-metallic<br />

materials or components used in the construction of groundbased<br />

C-E-M equipment and its protective shelters, vans, and<br />

radomes. Repair parameters in this Chapter shall not be construed<br />

as specifying the extent of repair or refinish required,<br />

except where it is determined that repair of the existing defects<br />

will prevent the equipment from meeting operational requirements<br />

or will exceed allowable physical tolerances. The general<br />

methods described in this Chapter shall be used in<br />

conjunction with the equipment system specific maintenance<br />

manuals, instructions found elsewhere in this manual, MIL-<br />

HDBK-454, <strong>TO</strong>s 1-1-689-series, 1-1-691, 00-25-234, 31-1-69,<br />

31-1-75, 35E4-1-162, and 00-25-108, and all specifications<br />

and drawings pertinent to maintenance on the equipment in<br />

question.<br />

repair, and shall pose no undue safety hazards for operating<br />

personnel when used according to manufacturer's instructions.<br />

4.3.4 Safety and Health. Repairs shall be conducted in<br />

accordance with all personnel safety and health standards pertinent<br />

to the type of equipment under repair and for the maintenance<br />

site used for the repair activity.<br />

4.4 GENERAL REQUIREMENTS.<br />

4.4.1 Wood.<br />

4.4.1.1 Inspection. Wood structures and surfaces shall be<br />

inspected at frequent periodic intervals to determine if they are<br />

damaged and the extent of damage to the wood material and to<br />

any applied protective coatings (see Figure 4-1).<br />

4.2 MATERIAL SUBSTITUTIONS.<br />

Repair materials and processes shall be in accordance with<br />

applicable portions of system specific manuals or <strong>Air</strong> <strong>Force</strong><br />

technical data. If a satisfactory substitute cannot be found or if<br />

any doubt exists as to the applicability of the substitute, forward<br />

the problem along with a recommended solution to the<br />

equipment System Program Manager (SPM) for resolution.<br />

4.3 WORKMANSHIP AND SAFETY.<br />

The following list of general requirements establishes repair<br />

standards of a nonspecific nature that determine acceptability<br />

of repaired equipment:<br />

4.3.1 Components and Parts. Components and parts shall<br />

be repaired in a thoroughly workman-like manner using best<br />

manufacturing practices.<br />

4.3.2 Dimensions and Tolerances. Dimensions and tolerances<br />

shall be in accordance with drawings and specifications<br />

pertinent to the equipment under repair. If not specified,<br />

dimensions and tolerances shall be in accordance with best<br />

manufacturing practices for the type of equipment being<br />

repaired.<br />

4.3.3 Tools and Tooling. Tools and tooling used for maintenance<br />

and repair shall be appropriate for the task, in good<br />

Figure 4-1. Electronic Shelter: Installed Wood Cabinetry<br />

4.4.1.2 Repair. Repair wood-to-wood joints using means<br />

comparable to those used in the original fabrication. Glued<br />

joints shall be securely bonded. Gluing, if required, shall be<br />

completed prior to application of sealers, if possible. If not<br />

possible, the surface areas to be glued shall be masked. Reinforcement<br />

of glued joints using metal brackets or plates is<br />

permissible, provided external appearance or equipment function<br />

and operation is not altered.<br />

4.4.1.2.1 Deeply scratched or gouged wood shall be repaired<br />

with an approved wood filler and sanded smooth and flush<br />

with surrounding surfaces. After sanding, the repaired area<br />

shall be sealed with an approved clear wood preservative per<br />
