7.2 SE SWA AOR DEPLOYMENT.
7.2.1 Pre-deployment. Prior to deployment of SE to SWA
AOR it is recommended that the following actions be taken to
prevent sand/dust intrusion during deployment.
a. Accomplish a complete SE wash per Chapter 2 prior to
deployment.
b. Inspect entire exterior/interior surfaces for missing or
deteriorated primer/paint.
c. Touch-up all deficient areas with approved processes
and materials per Chapter 3.
d. Inspect and remove any standing water in unit.
e. Inspect and clean all drain holes.
f. Minimize lubrication by removing all excess
greases/oils to limit sand/dust entrapment.
7.2.2 Deployment Location. Soils in SWA AOR locations
should be considered suspect and removed on a regular basis.
A constant regimen of vacuuming or brush removal of
sand/dust accumulations is necessary to reduce potential corrosion
problems.
7.2.2.1 SE Units Requiring Additional Cleaning. Some
units require additional cleaning process due to air filters,
exposed lubrication areas, and areas that may be more prone to
sand/dust entrapment.

7.2.2.1.4 Open Circuit Boards/Cards. After cleaning open
circuit boards/cards per TO 1-1-689-3, apply a thin coat of
avionics grade corrosion preventive compound,
MIL-PRF-81309, Type III, to the board to insulate the circuits
from sand/dust intrusion.
7.2.2.1.5 Wire Bundles. Sharp angular sand/dust particles
can migrate into wiring bundles where vibration caused by
equipment operation can result in abrasive action that can
cause chafing of the wiring (Figure 7-5). Remove trapped sand
from around and between bundled wires to prevent electrical
problems.
7.2.2.1.1 Radiators, Vanes, Filters and Coils. SE that
have radiators, vanes, filters, and coils require additional
cleaning to remove dust/sand that can block cooling ports and
filters which are drawn into the units during operation. Clean
using engineering approved materials. Allow the units to dry
in an enclosed area to prevent airborne sand/dust from adhering
to wet surfaces.
7.2.2.1.2 Portable Hydraulic Test Stands/Mobile Air
Compressors. These units typically have interior fluid leaks
that will allow sand/dust to cling to the surfaces. Close inspection
and wipe down of these units are necessary to maintain
proper operation.
7.2.2.1.3 Aircraft Jacks and Tow Bars. Jackscrew bodies
and adjustable arms should be kept free of sand/dust at all
times. The use of locally manufactured permeable covers (Figure
7-4) will assist in prevention of sand/dust intrusion. Lubricate
units using corrosion preventive compound, MIL-L-
87177, Type 1 to reduce corrosion problems.
