Section IV. TASK L-100
a. Removal of TASK L-100.
(1) TASK L-100 is unaffected from the use of chemical solutions and abrasive cleaning techniques. The
recommended removal procedure is by scraping in a parallel direction along the surface of the blade. Use of a plastic
scraper with a sharp edge is highly recommended for this procedure. (See view B, figure 4-1 for local manufacturing of
scraper.)
CAUTION
Use of knives and razor blades on rotor blades surfaces should be kept to a
minimum. Rotor blade surfaces are extremely susceptible to cutting, scratching,
and gouging damage from the sharp edges of these instruments.
(2) If difficulty is encountered in peeling off the TASK 1-100, use a small pen knife or single edge razor blade with
holder to separate the TASK L-100 from the blade.
(a) Remove a one inch long strip of TASK L-100 from the leading edge of the rotor blade where the coating is
thickest utilizing a plastic scraper and/or pen knife.
(b) Carefully peel up a corner of the TASK L-100 coating where the one inch long strip was removed using a
plastic scraper.
(c) Grasp the peeled corner with a pair of plies and strip the TASK L-100 coating off by pulling towards the
aft of the blade. Repeat this process as necessary until full removal of TASK L-100 coating is completed.
b. Restoration of Rotor Blade After Removal of TASK L-100.
(1) Inspect area where L-100 coating was applied and look for possible damage to blade surface which might
have occurred during removal of L-100 coating.
(2) Repair/restore damage area in accordance with applicable TM.
(3) Lightly sand surface to be painted using abrasive paper (360 grit) or equivalent.
CAUTION
Heavy sanding will damage blade skin.
(4) Wipe sanded area with a clean towel.
