Inspect all bolt holes for elongation. As a general
rule, replace components with holes that are out-
of-round by 0.005” or more.
Replacement of the leaf spring
forward attach bolt P/N NAS6206-

not approved. The leaf spring

Inspect upper and lower leaf spring support blocks,
and attachment hardware for wear, corrosion, and
cracks. Ensure that the leaf spring support blocks
grip the leaf spring tightly to prevent leaf spring
movement fwd. and aft. Ensure flexible sealant
around contact edges of support blocks, lower
support block spacer and leaf spring is intact to
prevent collection of potential corrosive material in
this area. Lubricate 2 ea. Trunnion Zerk (grease)
fittings with MIL-G-81322 (Aeroshell 22).
(NOTE: If the tail gear spring and mount
components have been removed and reinstalled,
seal the contact edges where the spring, P/N 5079-
1, upper bracket, P/N 94131-9, lower bracket P/N
94131-11 and spacer P/N 95434-15 come together
with a high quality flexible silicone sealant or fuel
tank sealant to AMS-S-8802 (formerly MIL-S-8802)
to help block the collection of potential corrosive
contaminants in this area.)
