1a) Inspect each part for shot peen coverage in the lugbores of the 1.124 to 1.125 diameter holes including chamfers and the surface area of the lug denoted by -E- shall using liquid tracer dye per SS8766.

1b) Areas where coating has not been completely removed must be visually inspected with a 10X magnification verifying overlapping dimple appaerance. Verification of coverage for this method is a CC.

Nicks, dents, scratches, and tool marks on lug surfaces shall not exceed 0.0005 inch deep.

Per note 7 of forging drawing 70150-09127, the beta solution and heat treat overaged condition per Note 1 is a CC. Acceptance shall be obtained by non-destructive micro-examination per SS8452. Inspection of 100% of the forging is required.

Verification of .040 corner radius of bolt holes.
