2 Inspect thoroughly the left and right aft wing attach fittings for evidence of flaking
paint and/or corrosion. (Flaking paint may be a symptom of hidden corrosion.) If no
corrosion exists, continue with these instructions.
a If corrosion is superficial and there is no metal flaking and/or pitting, clean and
paint fittings, using a good quality aircraft primer.
b If serious corrosion is found, consult the Piper Illustrated Parts Catalog (P/N
753-689) for replacement part numbers and obtain and install new parts before
next flight. See paragraph 4-7a.
3 Upon completion of the inspection and after replacement or refurbishment of fittings,
treat the aft attach fittings area using DINOL AV 8 corrosion compound (P/N 89500-
800). The treatment may be brushed or sprayed.
4 Inspect insulation in and around the rear fittings.
a If insulation is wet or matted down where it has been wet, it will be necessary to
replace this insulation and it will be necessary to inspect all windows, doors,
and exterior panels leading to the cabin.
[1] Check door seals for deterioration, cracks, and voids in adhesive.
[2] Check window seals for voids, cracks, and deterioration.
[3] Perform a leak check with water to determine where the water is entering.
Cure all leak paths before continuing these instructions.
