### : 

### Note 1: Assumes 50% of 359 suspect disks are still in service; also assumes 50% of 180 disks in active service are in US engines; therefore, approximately 90 disks will require FPI and EC inspections and an average of one disk will be rejected and will require a replacement Note 2: Assumes an average of two re

- inspections by FPIand EC before the disk is retired. One disk will be removed from service for the entire re

- inspecti on cycle of 89 and 88 engines respectively

. Note 3: Cost does not include engine disassembl y, inspection, and consumables incurred during normal periodic hot section engine inspection. Cost does not include consumables during unscheduled engine removals.
