To determine amount of rework needed, use the following formula:
On the leading and trailing edge of the blade, measure the depth of the damage,
and multiply this number x 10 (see Example 2, above). Rework the area surrounding
the damage 10 times the depth of the damage.
On the face and camber of the blade, measure the depth of the damage, and
multiply this number x 20 (see Example 3, above). Rework the area surrounding the
damage 20 times the depth of the damage.
