INTRODUCTION

1 PURPOSE.

This checklist is a step-by-step guide in abbreviated form for use as a reference to ensure accomplishment of selected tasks by a predetermined sequence procedure. The intent of this checklist is to eliminate the probability of omission of a step in the accomplishment of the intended task. The procedures contained herein are presented in the shortest practical form for use by qualified personnel and are not intended to provide full technical instructions. This checklist provides, in an abbreviated form, procedures for appropriate tasks, inspections, etc. These procedures are derived from, but do not replace, the detailed proce-dures contained in Technical Order (TO). When malfunctions occur reference to the TO shall be made.

2 SCOPE.

When unique operational requirements, contingencies, droughts, or facility limitations severely impact a unit’s ability to wash as prescribed in TO 1-1-691, Table 3-1, and alternatives (such as aircraft rotation, substitute wash facility, etc.)

have been pursued but could not be obtained, the requirement may be temporar-ily waived by submitting a Technical Assistance Request (TAR) in accordance with TO 00-25-107 and AFMCMAN 63-1202. In the request, include current environmental severity, previous wash date, requested wash date, as well as details pertaining to the inability to perform the wash and actions taken to pursue alternatives. The After Wash Corrosion Inspection requirements contained in TO 1C-130A-23CL-1, Chapter 5 shall still be accomplished on the original wash cycle due dates during the waiver period. MAJCOM coordination is required on the TAR. MAJCOM approval serves as consent to the greater risk of future C-130 maintenance cost and schedule increases due to corrosion not prevented by the aircraft wash.

NOTE

• This checklist provides instructions for aircraft washing. These instructions do not replace detailed instructions in TO 1C-130A-23 and TO 1-1-691, but are to be used as a guide while performing the work to ensure that no item is overlooked.

• It is expected that technicians using this checklist will not need detailed instructions for performing routine maintenance opera-tions. However, less experienced personnel may find it helpful to make occasional reference to the maintenance manual.

• The table of contents preceding these instructions enables quick access to the required procedure.

SAFETY SUMMARY

1 GENERAL SAFETY INSTRUCTIONS.

This safety summary includes general safety precautions and instructions that must be understood and applied during operation and maintenance to ensure personnel safety and protection of equipment. Prior to performing any task, the WARNINGs, CAUTIONs, and NOTEs included in that task shall be reviewed and understood.

2 WARNINGS, CAUTIONS, AND NOTES.

WARNINGs and CAUTIONs have been strategically placed to highlight operating or maintenance procedures, practices, conditions, or statements which are considered essential to protection of personnel (WARNING) or equipment (CAUTION). WARNINGs and CAUTIONs immediately precede the step or procedure to which they apply. NOTEs are used to highlight operating or maintenance procedures, practices, conditions, or statements which are not essential to protection of personnel or equipment. NOTEs may precede or follow the step or procedure, depending upon the information to be highlighted. The headings used and their definitions are as follows:

An essential operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in injury to or death of personnel, or long-term health hazards.

An essential operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in damage to or destruction of equipment, or result in loss of mission effective-ness.

NOTE

An essential operating or maintenance procedure, condition, or statement which must be highlighted.

3 CLEANERS/CHEMICALS.

Give cleaners/chemicals special care. Keep cleaners/chemicals in approved safety containers and in minimum quantities. Some cleaners/chemicals may have an adverse effect on skin, eyes, and respiratory tract. Observe manufacturer’s

CUI

TO 1C-130A-23CL-1

ix warning labels and current safety directives. Use cleaners/chemicals only in authorized areas. Discard soiled cloths in approved safety containers. Consult the local Bioenvironmental Engineer and/or Material Safety Data Sheets (MSDS) for specific precautions, protective equipment, hazardous materials (i.e., Ozone Depleting Substances), components, and ventilation requirements.

4 PERSONAL PROTECTIVE EQUIPMENT (PPE).

Wear protective clothing/equipment (gloves, apron, eye protection, etc.)

approved for the materials, procedures, and tools being used. Contact supervisor for guidance. If necessary, the Bioenvironmental Engineer or the Base Safety Office should be contacted for guidance.

5 JEWELRY.

Remove rings, watches, and other metallic objects which may cause shock or burn hazards. Snagged finger rings have caused many serious injuries. Unless specifically allowed by shop safety procedures, remove finger rings during all maintenance activity.

6 COMPRESSED AIR.

Compressed air used for cleaning can create airborne particles that may enter the eyes. Pressure will not exceed 80 Pounds per Square Inch (PSI) and then only with effective chip guarding and personal protective equipment.

7 SAFETY PRECAUTIONS.

The following safety precautions shall be observed while performing procedures in this manual.

• Dangerous voltages are present at system connectors. Ensure power is OFF prior connecting or disconnecting cables.

• Do not wear metal frame glasses, rings, watches, or other metal jewelry while working on electronic equipment.

• Some cleaning materials specified herein are flammable and/or toxic.

Keep away from open flame or other ignition sources. Provide adequate ventilation and avoid skin/eye exposure.

• Cleaning with compressed air can create airborne particles that may enter eyes or penetrate skin. Pressure shall not exceed 30 Pounds per Square Inch Gage (PSIG). Wear goggles. Do not direct compressed air against skin.

The supervisor will ensure that personnel are familiar with DAFMAN 91-203, CUI

TO 1C-130A-23CL-1

x

TO 1C-130A-23, and TO 1-1-691. The supervisor will brief all personnel of personal injury hazards as follows:

• Avoid breathing toxic fumes.

• Avoid skin contact with compounds.

• Avoid climbing on wet surfaces by using long handled brushes and maintenance stands. When it is absolutely necessary to walk on aircraft wing during washing, an approved fall restraint system will be used, and extreme care will be exercised.

• Guard rails must be used properly on stands.

• In the event of chemical injury, seek medical aid immediately.

• In the event of cleaner being splashed in eyes, rinse thoroughly with fresh water for 15 minutes and seek medical attention.

• Remove clothing saturated with cleaning solution immediately, and flush exposed skin areas with fresh water. Failure to comply may result in injury to personnel.

• While washing and cleaning the aircraft, personnel will wear eye protection, rubber gloves, and clothing, as required by TO 1-1-691.

However, when high temperatures are experienced outside, personnel will take an occasional break from washing activities to preclude the possibility of heat prostration.

• Solvents will not be mixed with the cleaning compound solution.

• Compressed air used for drying purposes or cleaning can create airborne particles that may enter the eyes or penetrate skin. Eye protection is required. Do not direct compressed air against skin.

Compressed air shall be dry and oil-free. Air pressure shall conform to the identified task pressure and not exceed 15 Pound per Square Inch (PSI).

• Cleaning compounds MIL-PRF-87937 and MIL-PRF-85570 are toxic to skin, eyes and respiratory tract. Avoid skin and eye contact.

Good general ventilation is normally adequate. Industrial safety goggles or face shield and chemical resistant gloves such as rubber, nitrile, neoprene, or latex shall be worn when skin contact is possible. Consult the local safety office and Bioenvironmental Engineering for Personal Protective Equipment (PPE) require-ments.
