Proper inspection and protection (refinishing) of bonded areas is required.
COMPLIANCE PROCEDURE:
1. Remove main rotor blade tip cover(s) and clean the blade(s).
2. Feather edge of paint bordering bare metal by hand-sanding spanwise with 220-grit or finer wet-or-dry aluminum-oxide or silicon-carbide abrasive paper. Do not remove metal.
CAUTION Do NOT use power tools or chemical paint strippers to remove paint.
3. Mask area to prevent overspray contamination.
4. Clean bare metal to be painted with a lint-free cloth dampened with enamel cleaner.
5. Prime bare metal, including any bare metal which will underlie tip covers, with at least two coats of Desoprime CA7501 epoxy primer (or equivalent). Scuff primer prior to applying second coat. Desoprime technical data is available online at:
