28.10.2 Cleaning
MATERIALS REQUIRED
NUMBER NOMENCLATURE
C-339 Ethyl Alcohol
CAUTION
WHEN USING HOT WATER TO CLEAN FUEL
CELL, WATER TEMPERATURE SHALL BE
LIMITED TO 160°F (71°C). DO NOT USE
SOAPS OR STRONG DETERGENTS WHEN
CLEANING CELL. SOAPS CAN REACT WITH
FUEL TO FORM A COMPOUND WHICH TENDS
TO PLUG FILTERS. DO NOT USE METHYL-
ETHYL-KETONE (MEK) OR SIMILAR
SOLVENTS FOR CLEANING CELLS.
28.10.2.1 Remove all fungus growth from cell
by hand or with soft scrub brush using warm or
hot water.
28.10.2.2 If fungus is observed in cell cavity,
wipe cavity with clean cloths moistened with ethyl
alcohol (C-339).
28.10.2.3 Inspect other cells for presence of
fungus growth. Remove any affected cell and
clean as required.
28.10.3 Inspection
28.10.3.1 Inspect fuel cell for cracks and
scuffing. Replace cells if unserviceable.
28.10.3.2 Inspect all fittings and ensure
serviceability of threaded inserts. Replace if
unserviceable.
28.10.4 Installation
MATERIALS REQUIRED
NUMBER NOMENCLATURE
C-311 Adhesive
C.408 Talcum
Powder
C-471 Lacing Cord
CAUTION
DO NOT HANDLE FUEL CELL WHEN CELL
TEMPERATURE IS BELOW 65°F (18°C).
LEAVE FUEL CELL IN ORIGINAL SHIPPING
CONTAINER UNTIL READY TO INSTALL IN
HELICOPTER.
NOTE
Work-aids to align fuel cell fittings during installation
may be fabricated by cutting off heads of two AN4
bolts approximately 6 in. (15.24 cm) long. Grind
cutoff ends to bullet shape, removing any burrs.
Install work-aids in two nut-plates of fuel cell port
being attached, and use work-aids to hold alignment
with mating parts while starting prescribed attaching
bolts into remaining nut plates. Ensure attaching
bolts are correct thread size and length: Bolts too
short will not have enough thread engagement; bolts
too long will bottom out and cause incorrect torque,
possible damage to nut plate, and fuel leakage.
28.10.4.1
Inspect fuel cell cavity for cleanliness
and smooth condition of all interior surfaces. Apply
talcum powder (C-408) to cavity to prevent cell
adhesion.
28.10.4.2
Install aft outboard left cell as follows:
28.10.4.2.1 Place packings in grooves of
interconnect, crossover, and vent port fittings.
Secure packings in place with a fuel soluble
adhesive (0-311) or equivalent.
28.10.4.2.2
Insert fuel cell into cavity. Use care to
avoid damage to fuel cell.
NOTE
Fuel tank assemblies 212-360-602-101 (left side)
and 212-360-602-102 (right side) do not have lacing
rings. Vent, interconnect, and filler fitting
attachments will support tank position in airframe
structure after installation.
28.10.4.2.3
Lace fuel cell in position using a single
