Downloaded from https://www.everyspec.com MIL-STD-3001-4(AS) 5.3.1.1.5 Disassembly. For major components such as engines, instructions shall include sequential procedures for disassembly of sections, modules and subassemblies into component parts. Disassembly of component parts shall be covered only to the extent required for the authorized level of maintenance. Precautions to be observed and critical dimensions to be recorded shall be included. For the transportation of aircraft, any disassembly of the aircraft required to load the aircraft aboard the transport shall be provided. 5.3.1.1.6 Cleaning and corrosion control. a.

Peculiar instructions for cleaning the equipment and components shall be prepared. Only approved cleaning materials shall be used. Precautions to be observed and hazardous materials warnings shall be included, as applicable. b. Methods and procedures for aircraft cleaning and general upkeep shall be prepared. c. For major components such as engines, specific instructions for parts and subassemblies and cleaning methods such as special agents, ultrasonic, and compressed air not covered in general manuals or standard practices WPs shall be prepared. References to these documents shall be made, as necessary. Precautions to be observed during cleaning shall be specified.

Instructions relating to preservation of metal parts and surface treatment after cleaning shall be included. 5.3.1.1.7 Inspection. a. Instructions shall be prepared for inspection of the equipment and components during maintenance to determine when parts shall be replaced or repaired. Inspection methods, equipment required, and measurable accept or reject requirements and standards shall be prepared. b. For engines and other dynamic components (such as transmissions and rotor heads), procedures shall include the required inspection methods, support equipment, and instructions for inspection of engine parts within the scope of the applicable level of maintenance.

When applicable, tables or charts shall be used to present inspection criteria with specific applicable rework required for each out of tolerance condition (see figure 1). Inspection instructions shall encompass: failure, wear, fluid sampling, damage, corrosion, leakage, pressure checks, aging, burning, malfunctioning, deformation, and deterioration that can be expected to occur during service. Allowable service limits and adequate standards for determining when parts should be repaired or replaced shall be included. Illustrations shall be prepared whenever necessary to augment inspection tables and shall be clearly identified to correlate table(s) to illustration(s).

Procedures shall be included for performing special inspections required when the component has operated beyond permissible limits, such as overspeed, over temperature, over torque, or sudden stoppage. Any requirements for special inspection by nondestructive methods shall be specified. 5.3.1.1.8 Repair. a. Instructions shall be prepared for the repair of the equipment and its components to the extent authorized by the approved MP to restore an item to a completely serviceable or fully mission capable status. Minor repair actions that do not affect the integrity of the item shall also be included (e.g., fuse, lamp, or knob replacement).

Minor repair actions of this type are not considered "complete repair actions" and as such may not justify assignment of an SM&R code (refer to NAVAIRINST 4423.11). Tables of acceptable tolerances and limits shall be included. b. For major components such as engines, instructions shall be included for necessary repair to restore the engine section, module, or major subassembly to a completely satisfactory condition. Repair 11
