Aft Stowage Bay
Cyclic Stick Controls
Category II areas include enclosures shielding non-mission critical equipment and wire harnesses.
Shielding effectiveness: 40-20 db.
(b) EMI conductive coating Category II areas. Conductive coating in these areas are non-mission critical
equipment and wire harnesses.
1 Conductive coating paint will protect these areas up to 20 db. If coating is discovered missing in
these areas, flight operations are permissible in E.M.I. environments. Repair these areas at next
phase maintenance interval.

Category III areas include enclosures incorporating shading techniques. Shielding effectiveness:
(c) EMI conductive coating Category III areas. Conductive coating in these areas are least critical.
1 The conductive coating in these areas should protect up to 10 db. If the coating in these areas is
damaged, it is permissible to operate the aircraft in E.M.I environments. The coating is to be
repaired at the next phase maintenance interval.
