CHAPTER 1 INTRODUCTION
1-1. GENERAL.
1-1.1. Today’s military avionic systems assume a significant share of the responsibility for mission completion, performance capability, and overall system safety. The role of avionics includes mission essential equipment, flight critical equipment, and aircraft hardware. For example, navigation, communications, electronic warfare, weapon management, flight/engine controls and displays, and wiring are all considered avionics. Electronics and electrical power systems are also considered avionics. The reliability of these complex systems in any environment is critical for aircraft flight and mission essential functions.
NOTE
In this manual, use of the term "avionic systems" shall refer to any device that uses electrical power. The term “avionic technician” shall include the aviation electrician, aviation electronic technician, or any personnel authorized to perform maintenance on avionic systems.
1-1.2. Corrosion is a major cause of avionic equipment failures, particularly while installed in military aircraft. In many cases, even minute amounts of corrosion can cause intermittent malfunction or complete failure of the equipment. Past experience shows that in order to obtain certain electrical characteristics, for example, low electromagnetic interference (EMI), a compromise in the design selection of materials might be needed (for example, the use of conductive adhesive). Sometimes such compromises can lead to corrosion problems that are aggravated by exposure to varying environmental conditions (for example, EMI corrosion). Avionic equipment is routinely exposed to varying environmental conditions. These conditions include changing temperatures and pressures, varying humidity, dust, dirt, and industrial pollutants in the atmosphere that often initiate corrosion.
1-1.3. The types of corrosion that occur on avionic equipment are similar to those found on airframe structures. The difference between avionic and airframe corrosion is that small amounts of corrosion in avionic equipment can cause intermittent malfunction or complete failure, while it may not impact airframe structures.
1-2. PURPOSE. The purpose of this manual is to provide information on materials and procedures to prevent, control, and repair corrosion damage to avionics on land or at sea.
1-3. SCOPE. The material in this manual contains basic avionic corrosion prevention and corrective maintenance information to be used at the Organizational/Unit and Intermediate levels.
1-4. ARRANGEMENT OF MANUAL.
1-4-1. A complete set of manuals to perform avionics and electronics cleaning and corrosion control functions consists of Volumes I, III, and IV (Navy and Army) or Volumes I, III, and V (Air Force).
1-4.2 Arrangement of Volume III. Volume III consists of ten chapters, arranged as shown in Table 1-1. 1-5. RELATED PUBLICATIONS. Tables 1-2 (Navy), 1-3 (Air Force), 1-4 (Army), and 1-5 (Other) list technical publications that may be used as supplemental references by personnel involved in cleaning and corrosion control.
1-6. CONSUMABLES AND EQUIPMENT. Procurement information for ordering consumables and equipment referenced in this volume may be found in Volume IV (Navy and Army) or Volume V (Air Force) of this manual.
This volume was prepared under the technical cognizance of the Chemistry and Materials Division, NAVAIR China Lake, China Lake, California.

CHAPTER 2
CLEANING AND LUBRICATION 2-1. GENERAL.
2-1.1. The materials, equipment, and techniques described in this chapter are intended to assist the avionic technician at the Intermediate Maintenance Activity (IMA). This includes the cleaning and drying of avionic equipment. Generally, where support equipment is available, corrosion removal, cleaning, and drying is more efficient.
2-1.2. Gross contamination requires support equipment capable of cleaning and corrosion removal as specified in the cleaning tracks (paragraph 2-4). The alternate cleaning procedures listed (paragraph 2-5) are considered sufficient for "day-to-day" cleaning and when support equipment is not available. 2-1.3. Pending standardization, use only support equipment that meets the general specifications as outlined in Volume IV (Navy and Army) or V (Air Force), Chapter 4.
2-1.4. The support equipment that is available in the supply system is listed in Volume IV (Navy and Army) or V (Air Force), Chapter 3. The general operating procedures and limitations for all of the various support equipment are listed in this chapter.
2-2. AVIONIC CORROSION CLEANING FACILITY. 2-2.1. REQUIREMENTS. Where space permits, a separate avionic corrosion control cleaning facility center shall be established as specified in OPNAVINST 4790.2 (Navy) or TO 00-20-1 (Air Force). See Figure 2-1 and Figure 2-2 for an example of an avionic cleaning facility arrangement. The avionic cleaning facility and staffing shall include the following as a minimum:
CAUTION
Maintenance personnel should be concerned about safety at all times. Cigarette smoke, food, and beverages can contaminate and damage avionic equipment. Do not smoke or have food or beverages in the same work space as maintenance operations.
a. Adequate space for safe operation of avionic cleaning and corrosion removal equipment.
b. Personnel trained in the operation of each piece of support equipment.
c. Quality assurance inspectors trained in the operational characteristics and restrictions of each piece of support equipment.
d. Operating instructions for each piece of support equipment.
e. Safety equipment and clothing as required by local directive and this manual.
f. Personnel trained in recognition of corrosion on avionic equipment as specified in this manual.
g. Avionic technicians who can recognize the various electrical and electronic components.
2-2.2. ALTERNATE REQUIREMENTS. Support equipment shall be placed where fumes, overspray, dust, or other residual materials will not contaminate avionic modules or components. The requirements specified in paragraph 2-2.1shall also apply wherever cleaning and corrosion removal equipment is operated. Close supervision and sufficient quality assurance personnel/procedures are required at the avionic cleaning facility. Cleaning and corrosion removal equipment can be detrimental to some avionic components. The decision to use cleaning and corrosion removal equipment shall be the responsibility of the avionic cleaning facility supervisor.
2-2.3. INDUCTION PROCEDURES. The induction of avionic equipment for cleaning and/or corrosion control shall be as follows:
2-2.3.1. Induction of avionic equipment shall be documented on the appropriate maintenance action forms (MAFs) in accordance with procedures established under OPNAVINST 4790.2 (Navy), TO 00-20-1 (Air Force), or DA PAM 738-750/DA PAM 738.751 (Army).
Figure 2-2. Typical Track 8 Equipment Layout See Figure 2-4.
2-2.3.2. Each module or component inducted shall be inspected for:
a. The type of contamination. b. The extent of corrosion damage.
c. Identification of items considered sensitive to cleaning and corrosion removal procedures.
2-2.3.3. After inspection, the "cleaning track" shall be selected by the criteria provided in paragraph 2-4. 2-3. MATERIALS AND SUPPORT EQUIPMENT REQUIREMENTS.
2-3.1. GENERAL. Avionic technicians must understand the functions, capabilities, and restrictions that apply to each material and piece of support equipment. This prevents damage to personnel and avionic equipment that could result from improper use. 2-3.2. MATERIALS. Consumable materials listed in Volume IV (Navy and Army) or V (Air Force), Chapter 2, and equipment listed in Volume IV (Navy and Army) or V (Air Force), Chapter 3, shall be used for corrosion control. These materials have been approved only after extensive testing to prove their ability to perform properly and effectively. Materials or processes considered to be an improvement over existing ones, after local laboratory analysis and evaluation, shall be forwarded to the Aircraft Controlling Custodians (ACC) or System Program Manager (SPM) for submission to the parent service organization for further evaluation. When approved materials are not available, substitutions shall only be made by the appropriate ACC/SPM.
2-3.3. MATERIALS USE. Only those materials listed in this manual shall be used for cleaning or corrosion control of avionic components. Materials listed in other manuals shall be used only when required procedures are not covered by this manual. Promising materials technology, after local laboratory analysis and evaluation, shall be forwarded to the parent service organization for further evaluation. When several methods or materials are listed, the preferred one is listed first, with alternates following.
2-3.4. SUPPORT EQUIPMENT. Tools and support equipment authorized for cleaning and corrosion removal on avionics equipment are listed in this chapter,
Chapter 4, and Volume IV (Navy and Army) or V (Air Force) of this manual.
2-3.5. SUPPORT EQUIPMENT USE. Each piece of support equipment has been selected to perform specific functions. These intended functions are identified in Chapter 4 and include general limitations applicable to each type of support equipment. Maintenance personnel should refer to the appropriate support equipment operating manuals for specific operating instructions.
2-4. CLEANING TRACKS.
2-4.1. GENERAL. A cleaning track represents a definite process that applies to a particular type of contaminant or corrosion product. This includes consideration for the restrictions that may apply to a specific piece of support equipment and/or avionic component. It is important that cleaning equipment operators have a thorough knowledge of electrical and electronic equipment. This should be supplemented by a knowledge of which components can be processed by a particular cleaning track. These cleaning tracks are shown in Figure 2-3.
2-4.2. CLEANING TRACK SELECTION CRITERIA. The selection of the cleaning track to be used is based on the following criteria:
NOTE
Always select the mildest form of cleaning that will accomplish the task.
a. Type and extent of the contamination or corrosion.
b. Accessibility to the contamination or corrosion. c. Type of avionic equipment.
2-4.3. TYPE AND EXTENT OF CONTAMINATION. Table 2-1 describes the various forms of contamination and the cleaning track best suited for each. There is more than one track available for cleaning each type of contamination. Use hand-cleaning procedures as alternatives if cleaning tracks are not available. 2-4.4. CLEANING TRACK PRESELECTION REQUIREMENTS. The avionic cleaning facility supervisor or equipment operator shall identify the
Figure 2-3. Cleaning Track Diagram
type of contamination and extent of the damage to select the correct cleaning track. Experience has shown that most avionic equipment has dirt, dust, or some form of corrosion present, and requires cleaning. If contamination or corrosion is not evident, confirmation via inspection by an experienced avionic technician is required.
2-4.5. ACCESSIBILITY TO CONTAMINATION AND CORROSION. Visual inspection of avionic components
corrosion damage. Visual inspection also determines the cleaning method required to remove contaminants or corrosion from tight areas. The aqueous ultrasonic and solvent ultrasonic cleaners provide the most efficient means of cleaning hard to reach areas. Consideration must also be given to drying that follows the cleaning cycle. In some cases, the most efficient means of cleaning may require extensive drying. This makes the whole process less efficient.
2-4.6. TYPE OF AVIONIC EQUIPMENT. The criteria for selection of a cleaning track are also based on type of avionic component to be cleaned. A thorough inspection of the item to be cleaned is important to determine the type of circuitry and components involved. Table 2-2 is a guide for determining the cleaning track to use on various electronic and electrical components.
2-4.7. CLEANING RESTRICTIONS.
2-4.7.1. Selection of the cleaning track is a decision to be made by the avionic cleaning facility supervisor. Certain circuit components can be damaged by support equipment.
2-4.7.2. The use of support equipment on certain avionic equipment and components is restricted (paragraphs 2-5.2. to 2-5.2.5.3.).
2-4.8. CLEANING TRACK IDENTIFICATION. The Cleaning Track Diagram, Figure 2-3, shall be used in conjunction with Cleaning Track Legend, Table 2-3. The cleaning track legend defines each element of the cleaning track. Each function and subfunction on the cleaning track is assigned an alphanumeric code. These characters are used to identify the cleaning track for recordkeeping purposes. It may be desirable to keep a log of all avionic equipment and components processed through the cleaning tracks. In such cases, the cleaning track number would identify exactly the process used when cleaning a particular component.
2-4.9. CLEANING TRACK EXAMPLE. As an illustrative example of cleaning track use, assume the cleaning track is "BCSR235". This would correspond to the following maintenance actions (refer to Figure 2-3 and Table 2-3):
a. B - Clean with the abrasive tool and glass beads. b. C - Scrub with cleaning brush.
c. S - Clean with water base spray with one ounce of detergent, MIL-D-16791, in 1 gallon of fresh water at a maximum of 30 psi.
d. R - Rinse with water base spray with fresh water at a maximum of 30 psi.
