The salvable components of the fuse-
lage, wings, empennage and movable
surfaces should be processed as fol-
lows. Clean the aircraft interior and
exterior using steam under pressure
with steam cleaning compound. Direct
the steam into all seams and crevices
where corrosive water may have pene-
trated. Avoid steam cleaning electrical
equipment, such as terminal boards
and relays. Areas that have been steam
cleaned should be rinsed immediately
with either hot or cold fresh water.
Touch up all scratches and scars on
painted surfaces using zinc chromate
primer or preservative. Undrained hol-
low spaces or fluid entrapment areas
should be provided temporary draining
facilities. Remove and replace all
leather, fabric upholstery, and insula-
tion. Plastic or rubber foam that can-
not be cleaned of all corrosive water
must be replaced. Clean metallic and
other non-metallic areas, excluding
acrylic plastics, with warm water. Re-
place porous materials exposed to wa-
ter immersion unless surfaces are ade-
quately sealed to prevent penetration
by water. Virtually all solvents and
phenolic type cleaning agents are det-
rimental to acrylics and will either sof-
ten the plastic or cause crazing. Re-
move instruments and radios and ap-
plicable cables and plumbing, and re-
pair and inspect as necessary.
All drain plugs or drive screws in tub-
ular structures should be removed and
the structure blown out with com-
pressed air. If water has reached the
tubular interiors, carefully flush with
hot fresh water and blow out water
with compressed air. Roll the structure
as necessary to remove water from
pockets. Fill the tubes with hot linseed
oil, approximately 180 °F, drain oil
and replace drain plugs or drive
screws.
