1-8. Rotor Blades
- Erosion/Spark Guard Coating (Removal).
Do not cut the rotor blade structure. Use extra caution when removing the material
from rotor blades made from composite materials.
This coating is relatively immune to most solvents and to abrasive cleaning techniques. The recommended removal
procedure is by scraping in a direction along the surface of the blade.
Rotor Blade Erosion Protection must be removed from the AH-64A and UH-60A
aircraft before operation in icing conditions.
