Attach Fittings Corrosion Control Inspection

Each five years, inspect the attach fittings shown in Figures 1 and 2 for corrosion and condition.
Repair/replace as required. When inspection and repair/replacement are 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 waterborne, chromated, fluid resistant, epoxy primer
(i.e. - PRC Desoto) or equivilent 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:
(1) Forward horizontal stabilizer attach points. Inside and outside fuselage. See Figure 2 to add an
access hole.
(2) Aft horizontal stabilizer attach points.
(3) Entire surface of tail cone interior.
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.
