CHAPTER 2

CLEANING AND WASHING

2.1 AIRCRAFT EXTERIOR AND INTERIOR CLEANING AND WASH-

ING PROCEDURES.

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

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 Bioenvironmen-tal Engineering for Personal Protective Equipment (PPE) require-ments. Good, general ventilation is normally adequate.

• Do not use a direct spray of water or cleaning compound on carbon brakes, wheels, or wheel hubs. If wheel bearings are suspected of contamination, corrosion, or loss of lubricant, remove wheel bearings, and re-lubricate in accordance with applicable system specific maintenance instructions and Technical Order (TO) 4W-1-61. If carbon brakes are suspected of contamination, decontaminate per applicable system specific maintenance instructions and TO 4B-1-32.

• Avoid direct water spray (over 30 Pounds per Square Inch (PSI)) to the AN/AAQ-24 LAIRCM, transmitter assemblies, AN/AAR-47 Missle Warning System (MWS) Sensor Windows, AN/AAQ-157 IRCMS Cover, and AN/ALE-47 MWS sensor filter to prevent equipment damage.

• Do not spray water stream directly at electrical connectors/cannon plugs in wing root and fillet area.

• Abrasive pads, including melamine wash pads/Magic Eraser pads, shall not be used on windows, windshields, or acrylic transparen-cies.

NOTE

• Cleaning solutions for different areas and type soils shall follow mixing directions in accordance with TO 1-1-691, Table 3-2.

• MIL-DTL-85054 (Cor-Ban® 35 Preferred) Corrosion Preventive Compound (CPC) may have been applied to some aircraft at Depot in accordance with TO 1C-130A-23. Specific Depot application locations are identified in the TO. The CPC application appears as a transparent salmon color hard finish which may have shade differences and possible runs/sags. Chapter 7, Section 1 covers Field Level CPC application instructions and application locations.

• Current specifications and associated Qualified Products List (QPL)/Qualified Product Database (QPD) authorized for total aircraft wash are listed in TO 1-1-691.

• Ensure all areas where MIL-DTL-85054 is applied are fully cured before sealing an area.

2.1.1 Exterior Washing Sequence. Ensure all drain holes are open and operative and then proceed in accordance with the following sequence. The following materials are approved for full exterior wash: MIL-PRF-87937, Types I, III, IV, and MIL-PRF-85570, Types I, II, III, IV. See TO 1-1-691 for specific instructions on the use of these materials. Clean the exterior surface area by area, starting at the lower surface and working upward.

NOTE

All areas must be kept wet with cleaning solutions or water at all times. Rinse off all overspray of solutions.

2.1.1.1 Soil Barrier Removal. Remove prior application of soil barrier before aircraft wash in accordance with TO 1-1-691.

2.1.1.2 Wash Wheel Wells.

a. Wash wheel wells, concentrating first on the interior well structure.

b. Clean landing gear components.

c. Rinse from top to bottom.

2.1.1.3 Wash Mid-Fuselage.

NOTE

Perform in conjunction with wing wash if possible.

a. Wash the under surface first, progressing upward.

b. Rinse from top to bottom.

2.1.1.4 Wash FWD Fuselage.

a. Wash under surfaces first, progressing upward. Start at mid-fuselage and spray forward.

b. Rinse from top to bottom.

2.1.1.5 Wash Aft-Fuselage.

Do not directly spray LAIRCM Turrets/Small Laser Transmitter Assembly (SLTA). Since it may be damaged by power wash pressure over 30 PSI. Failure to observe this caution could result in equipment damage.

a. Wash exposed areas of the Fuselage Station (FS) 737 bulkhead (above the belly band) and under the ramp closure panels (LT and RT).

b. Wash the under surface first (cargo ramp and cargo door), progressing upwards.

c. Rinse from top to bottom.

2.1.1.6 Wash Empennage.

a. Wash bottom of horizontal stabilizer.

b. Wash top of horizontal stabilizer.

c. Wash vertical stabilizer and that portion of aft fuselage subject to fluid run-down. Begin at base and wash to tip.

d. Rinse from tip to base, including aft fuselage.

2.1.1.7 Wash Wings.

a. Wash the lower and then the upper surfaces of wings. Start at fuselage wing root area and move toward wing tips.

b. Rinse toward centerline.

2.1.1.8 Wash Wing Root Panels and Interior Areas (Isochronal (ISO) and Post Desert Wash Only).

a. Protect electrical connectors on access panels and inside interior upper wheel well area with tape and barrier material as required.

b. Wash interior areas.

c. Rinse from top to bottom.

2.1.1.9 Thoroughly Rinse Aircraft Exterior Surfaces. After completion of wash, flush down all aircraft exterior surfaces to remove residual cleaning solutions.

2.1.2 Local Interior Cleaning. Interior areas of the aircraft subject to the accumulation of dirt, debris, and aircraft fluids residue shall be cleaned as required, for the prevention of corrosion, as well as, to afford the detection of a breakdown in the corrosion protection finishes originally applied.

Do not use high volumes of water inside the aircraft. Failure to comply may result in damage to equipment.

a. Remove caps and plugs or barrier paper from battery electrical receptacles.

Reconnect all aircraft electric batteries and secure battery quick discon-nects with 0.020-inch copper safety wire in accordance with TO 1C-130H-

2-24JG-30-1.

b. Apply external power to aircraft in accordance with TO 1C-130H-2-05JG- 00-1.

c. Lower cargo ramp in accordance with TO 1C-130H-2-52JG-00-1.

d. Raise cargo door to full up and locked position in accordance with TO

1C-130H-2-52JG-00-1.

e. Disconnect external power in accordance with TO 1C-130H-2-05JG-00-1.

f. Remove loose soil in the flight deck, cargo compartment, cargo ramp, and cargo door by vacuuming.
