Attach Fitting Corrosion Control Inspection

Each five years, inspect the attach fittings shown in Figure 1 for corrosion and condition. Repair/replace
as required. When inspection and repair/replacement is completed, reapply Dinitrol AV 8 (P/N 89500-
800) Corrosion Inhibiting Compound.
NOTE: For all fittings, inspection of the exposed portion is sufficient unless obvious or extensive
corrosion is apparent.
NOTE: Any part exhibiting flaking of the metal due to rust must be replaced.
NOTE: If aluminum skin or structure is corroded (beyond a light surface oxidation), the area must be
repaired or replaced.
NOTE: On any part being replaced, dip rivets in zinc chromate or equivilnt primer and install wet.
A. When inspection and repair or replacement are completed, allow sufficient time for primer to dry,
and apply Dinitrol AV 8 to forward vertical fin attach point.
CAUTION: READ PRECAUTIONS ON CONTAINER LABEL AND WEAR A CHARCOAL FILTER
MASK WHEN APPLYING DINITROL AV 8.
B. Apply Dinitrol by spraying or brush. Use an air or airless spray gun if available. A hand aspirator
bottle may be used if a sufficient fan spray pattern can be developed. Product should not be
thinned.
