echanics, erosion is the mortal enemy of aircraft rotor blades. And corrosion is
erosion’s Frst cousin. These two forces are always at work, so prevent erosion’s
attack on blades, and keep a watchful eye on corrosion’s attack everywhere else.
If your blades need a little touch-up paint, spray on a light coat of black paint to
help slow blade erosion. Don’t use too much, though, because you can throw off
the track and balance of your aircraft. And do not paint over blade serial numbers,
because they are used to track blade hours.
Cleaning, painting and preserving rotor blades is slightly different for Black
Hawks, Kiowa Warriors and Chinooks, so follow these tips:
UH-60A/L Blades
Clean the blades with water and cleaning compound, NSN 6850-01-429-2368.
±ollow the instructions in WP 1686 of the IETM TM 1-1520-Blackhawk.
Paint the blades with a coat of polyurethane, NSN 8010-01-576-2880, like it says in
WP 0585 of IETM TM 1-1520-Blackhawk.
