SCOPE
. This section discusses aircraft and
engine cleaning. For corrosion charts of the specific
aircraft, refer to the applicable maintenance instruction
manual (MIMs), or contact the Fleet Support Team
(FST) for the aircraft.
A-12. AIRCRAFT CLEANING.
Cleaning compounds
and materials which appear only in Appendix B
(Supplemental Requirements for Army Aircraft) are not
authorized for cleaning Navy aircraft. See Chapter 2 for
detailed information on aircraft cleaning procedures
and authorized materials and equipment.
A-13. EQUIPMENT FOR ENGINE CLEANING
.
A-13.1. JET ENGINE CORROSION CONTROL CART.
The corrosion control cart, P/N 65A102-J1-1, is designed
for cleaning and rinsing the compressor section of
turbine engines. It is a trailer mounted, self contained
mobile unit designed for shipboard use and shore
based operations (see Figure A-18). The cart consists
of a 33 gallon capacity solution tank and a work platform
area on top of the solution tank. There is a water supply

hose and applicator storage area on the right hand side.
Two air cylinders are mounted on the left hand side to
supply the air pressure needed to discharge the water
solution from the solution tank. The instruction plate and
schematic diagram are mounted on the left hand side to
provide information about operating the unit. The
33 gallon capacity solution tank is divided into two
separate compartments: a 7 gallon preservative
compartment at the front end of the unit and the 26 gallon
water compartment at the rear end of the unit. On top of
each compartment is a filler opening and at the bottom
of each compartment is a plug for drainage purposes.
The operational instructions of the cart are listed in
NAVAIR 19-20D-1 (Jet Engine Corrosion Control Cart).
Washing with MIL-PRF-85704 (Gas Path Cleaner) shall
be performed as follows:
a. Fill the 7 gallon forward tank with 1 gallon of
MIL-PRF-85704 Type II and 4 gallons of fresh water, or
with 5 gallons of MIL-PRF-85704 Type II RTU (ready
to use). Then fill the 26 gallon aft tank with fresh water.
b. Prepare the aircraft for turbine engine washing in
accordance with the applicable maintenance
requirements.
c. Spray the cleaning solution or fresh water as
required (see Table 2-1 for additional information).
A-13.2. CORROSION CONTROL SPRAY UNIT,
TRAILER
MOUNTED.
The
spray
unit,
P/N 76E04000-30A, stores and controls the delivery of
water, preservative oil, and cleaning solutions to the
compressor section of turbofan, turbojet, and turboshaft
engines. It is a self contained sprayer mounted on a
towable trailer (see Figure A-19). The spray unit consists
of a 200 gallon water tank and a 10 gallon oil/cleaning
solution tank. Compressed air from the compressor
assembly pressurizes the tanks for delivery of fluids.
The solution tank is a reservoir for storage of preservative
or cleaning solutions. Fresh water from the water tank
is usually used during corrosion control for rinsing. The
4:1 mixer assembly mixes four parts water to one part
chemical in the solution tank. The unit can also supply
compressed air directly to the aircraft being serviced.
The unit is secured to an aluminum chassis mounted on
a four wheel running gear. Operating instructions for
the unit are listed in NAVAIR 19-20D-2 (Corrosion
Control Spray Unit).
