b. Inspect the bolts visually for dents under the heads, and for scores or fretting corrosion on the bolt stem or shank. Inspect the bolts for cracks using a magnetic particle or equivalent inspection method.

c. Remove from further service bolts having dents under the head or scoring or fretting on the stem or shank, or bolts having a crack.

d. Install bolts and washers andtail rotor transmission assembly in accordance with SA330 Puma Service Bulletin No. 01.34, dated October 19, 1981, subparagraph C(4)(b), or FAA approved equivalent.
