Examination Angles for each probe included:

PA60°-80°L, PA40°-50°S, PA30°-6Q 0 L, & PA0°L. Examination tf s 3 -8 were divided into sections a -c. Examination tfs 15 -20 were divided into sections a -d. Remarks This examina tion was limited due to the proximity of the core support lugs. The e xamination coverage wa s 88%. Prepared By: Steven J. T1dd Signature: /\ ISwT Project Manager <.\
