4. All flying surfaces in the shaded areas
shown, plus all overlaps at L.E. & T.E.
..... Major wrinkles or bumps along more than 2" of chord are cause
for rejection in the wings, canard and vertical fin, particularly on
the top (compression side). This does not mean you have to reject the
whole wing - anything can be repaired by following the basic rule:
remove the rejected or damaged area and fair back the area at a slope
of 1" per ply with a sanding block in all directions. By watching the
grain you will be able to count the plies while sanding. Be sure the
surface is completely dull, and layup the same plies as you removed,
plus one more ply of BID over the entire patch. This will restore
full strength to the removed area.
.....Use this method to repair any area damaged for any reason -
inadvertent sanding through plies during finishing, taxiing a wing
into a hanger, etc.
