What was found
DURING DAILY INSPECTION, THE POSSIBILITY OF A TABLOCK FAILURE WAS INVESTIGATED USING A 'BRIGHT LIGHT'. THE ENGINE WAS REMOVED AND SENT TO EAC WHERE A BORESCOPE INSPECTION WAS PERFORMED. DURING THE INSPECTION, ONE 3RD STAGE BLADE TABLOCK WAS FOUND MISSING. THE 3RD STAGE BLADE FROM WHICH THE TABLOCK WAS MISSING HAD MOVED SLIGHTLY REARWARD, BUT HAD NOT YET CONTACTED THE 3RD STAGE STATOR (PN 685503). THE TABLOCK COMING LOOSE CAUSED INTERNAL DAMAGE TO OTHER PARTS OF THE COMPRESSOR. APPROXIMATELY 3 VANES FROM THE 2ND (PN 566282) AND 3RD (PN 385503) STAGE STATORS WERE DAMAGED.
