a. For permanent structure, all faying surfaces, seams, and<br />
lap joints outside of fuel wet and high temperature areas<br />
shall be protected with MIL-PRF-81733, Type II or IV,<br />
Class 1 or 2, Grade A sealant. Apply the sealing compound<br />
to one or both surfaces and squeeze the part<br />
together to ensure the complete coating of the entire<br />
mating or faying surface. Excess material squeezed out<br />
shall be removed so that the fillet remains at the joint<br />
edges. The fillet width shall not be less that 1/4 inch.<br />
For seams, the sealant shall fill the seam entirely up to<br />
flush with the surface. Joint, joggle, or cavity areas<br />
which could hold water shall be filled with MIL-PRF-<br />
81733, Type II, Class 1 or 2, Grade A, SAE AMS-S-<br />
8802, Class B, or SAE AMS-3276, Class B sealant.<br />

d. On faying surfaces, seams, or joints which require disassembly<br />
for maintenance, either SAE AMS 3267 (MIL-<br />
S-8784) or part No. PR-1773 low adhesion sealant shall<br />
be used (part No. PR-1773 sealant contains non-chromate<br />
corrosion inhibitors).<br />
NOTE<br />
SAE AMS 3255 (Skyflex®) sealing tapes or Av-<br />
DEC® HT3935-7 and HT3000 sealing tapes may be<br />
used in lieu of the low adhesion curing type sealants<br />
in many removable joint areas requiring periodic disassembly<br />
for maintenance when approved by the<br />
equipment SPM.<br />
