Description This Service Bulletin introduces an immersion ultrasonic inspection for limited population of CF6-80C2 stage 1 and stage 2 HPTR disks for improved reliability and outlines an accomplishment procedure for the inspection at the designated service shop.

C. Compliance Category 5 GE recommends that you do this Service Bulletin each time the stage 1 and stage 2 HPTR disks are removed from the engine.

Impact A This recommendation is to address a condition that may affect Flight Safety.

NOTE:This Service Bulletin can be accomplished in shop.

This Service Bulletin is offered to improve the reliability or performance of your GE product, or to help prevent the occurrence of the event or condition described in this Service Bulletin. If the operator elects not to participate in the bulletin, that decision will be taken into consideration by GE in evaluating future product performance issues that may arise in the operator's fleet.

D. Concurrent Requirements None.

E. Reason

(1) Objective:

To inspect critical areas of the stage 1 and stage 2 HPTR disks bore and web for subsurface anomalies which may have been introduced during the raw material melting process.

(2) Condition:

A CF6-80C2 stage 2 HPTR disk was found to have an anomaly due to a rare occurrence during raw material melting process, which resulted in an uncontained HPTR disk event.

(3) Cause:

Examination of the inclusion in the stage 2 HPTR disk revealed that the anomaly was introduced during raw material melting process.

(4) Inspection:

An immersion ultrasonic inspection procedure will be done to the stage 1 and stage 2 HPTR disks listed in paragraph 4., .APPENDIX A

(5) Substantiation:

The immersion ultrasonic inspection procedure described in this Service Bulletin has been proven to be capable of detecting material processing anomalies.

F. Approval This Service Bulletin contains no modification information that revises the approved configuration and therefore does not require FAA or regulatory approval.

G. Manpower After you get access to the stage 1 and stage 2 HPTR disks, you will need approximately 10 man-hours per disk to do the
