UPON DISASSEMBLY OF ENGINE A 4TH STAGE TABLOCK HAD FAILED ALLOWING THE 4TH STAGE COMPRESSOR BLADE TO MOVE AND CAUSE DAMAGE TO THE REST OF THE ENGINE. DAMAGE WAS SEVERE ANG CAUSED ENOUGH DOD THE ENGINE BLEED BAND COULD NOT OPERATE CAUSING THE OVERTEMP. THIS TABLOCK IS A PMA PART MANUFACTURED BY ABLE ENGINEERING. PART NUMBER 536211AA.
