What was found
(CAN) SHORTLY AFTER TAKEOFF THE RH ENGINE EXPERIENCED A SUDDEN LOSS OF POWER ALONG WITH A VIBRATION. THE ENGINE WAS SHUTDOWN, AN EMERGENCY WAS DECLARED, AND THE AIRCRAFT LANDED SAFELY WITHOUT FURTHER ISSUES. A QUICK INSPECTION THROUGH THE EXHAUST DETERMINED THAT THERE WAS SUBSTANTIAL DAMAGE TO THE LOW PRESSURE TURBINE BLADES (LPT BLADE). ONCE THE ENGINE RETURNED TO MAIN BASE, A BORESCOPE INSPECTION WAS COMPLETED TO DETERMINE THE EXTENT OF THE DAMAGE. IT WAS DETERMINED THAT A STAGE 2 HIGH PRESSURE TURBINE BLADE (HPT BLADES) SEPARATED AT THE ROOT CAUSING SIGNIFICANT DAMAGE TO THE SURROUNDING STAGE 2 BLADES. THIS BLADE AND FURTHER BROKEN PIECES THEN TRAVELED THROUGH THE ENGINE DAMAGING EVERY DOWNSTREAM COMPONENT. ALL LPT SECTION OF THE ENGINE SUSTAINED SIGNIFICANT DAMAGE. THE STAGE 1 HPT NOZZLE HAD SOME BURNING DAMAGE. FDR DATA REVIEWED DID NOT INDICATE ANYTHING ABNORMAL PRIOR TO THE ENGINE FAILURE. (TC# 20190718005)
