## Discrepancy

(CAN) DURING HSI THE CT DISK ASSEMBLY WAS FOUND RUBBING ON THE CT AIR SEAL. FURTHER INSPECTION FOUND THAT EIGHT BLADE ROOTS ON THE OPPOSITE SIDE OF THE DISK ALONG WITH THE DISK PLATFORM WERE GROOVED. THE DEPTHS OF THE GROOVES WERE TO AN UNACCEPTABLE LIMIT. THE CT DISK ASSEMBLY AND THE AIR SEAL WERE REPLACED.
