No recordable indications were detected during this examination.

Examination Angles for each probe used with procedure ISwT-PDl-AUT 5 include: PA60°-80°L , PA40°-50°S , PA30°-60°L , & PA0°L. E x amination Angles for probe used with procedure ISwT-PDl-AUT-4 include: PA5°-4 0°L , PA35°-45S. Exam #29 was divided in t o sections A -D (sections C & D were additional exams using specfic probes for improved examination coverage). The e x aminat i on was limited due to the proximity of the nozzle intregral extension.

The examination coverage was 84%. Reviewed i. Signature: . Tennessee Va ley Aut Reviewed By: \::)D..il\ I e.. Sign ANll Date: [ ;;i_ I I ( ,/
