## Discrepancy

(CAN) THIS ENGINE REMOVED FOR DIFFERENT REASON THAN HOT SECTION DAMAGE THAT FOUND LATER.  DURING PREMATURE HOT SECTION INSP ON ENGINE IT WAS FOUND THAT 6 CRACKS WERE FOUND ON 1ST STAGE TURBINE BLADES INITIATING FROM LEADING EDGE TIP CORNER & EXTENDING DOWN LEADING EDGE TOWARDS BLADE ROOT. EROSION CAN ALSO BE SEEN THROUGH PARENT MATERIAL. THESE BLADES DID NOT EVEN MAKE IT TO HOT SECTION INSP OF 3,500 HRS. IS NO LIFE ON THESE BLADES AT PRESENT.
