NOTE
Procedure for repair of titanium nose
cap and nickel erosion cap are similar.
Differences are noted in text. Repair
bond voids only if they reach to edge
of cap.
1.
Find size of void (1). Use 0.005 inch thick shim
as a probe. Mark outline of void with pencil or
chalk.
Do not damage fiberglass when
removing adhesive aft of nose cap.
2.
Remove adhesive squeezeout (2) at trailing edge
(3) of cap (4). Remove adhesive along full width
of void. Use aluminum scraper (APP E-29).
3.
Mask area around void (1). Use Teflon tape
(E399) (5) forward of cap trailing edge (3). Use
aluminum foil (E66) (8) and Teflon tape (5) aft of
cap trailing edge.
4.
Open void (1) at edge of cap (4). Use clean
0.005 inch thick shim stock.
5.
Position blade (7) so leading edge is higher than
trailing edge.
