REPLACE NICKEL EROSION CAP (AVIM)
(Continued)
5-66
8.
Remove erosion cap (2). Use aluminum chisels.
Begin with starter chisel at outboard trailing edge
of cap. Work inboard and forward. Use final
removal chisel.
8.1.
Weigh erosion cap (2). Record weight.
9.
Have helpers position and support blade (4) with
leading edge (5) up. Do not bend trim tab (6).
Adhesive removal is time consuming
and must be done with care. Damage
to the fiberglass can result in reduced
fatigue strength and an altered airfoil
shape.
10.
Scrape off adhesive from leading edge (5) of
blade (4). Use aluminum scraper.
11.
Allow blade (4) to warm several hours to room
temperature.
12.
Sand fiberglass surface lightly to remove
adhesive. Leave thin film of adhesive. Use care
not to change airfoil shape.
12.1.
Check titanium nose cap (6.1) in bond area for
voids that extend to trailing edge. Repair voids
(Task 5-66.1).
