## Discrepancy

PILOT COMPLAINT WAS SMALL COMPRESSOR STALLS ''POPPING SOUND'' OCCURRING WHEN THEY WOULD DROP COLLECTIVE.  THIS WAS AN INFREQUENT OCCURRENCE THAT WAS HAPPENING OVER A PERIOD OF DAYS PRIOR TO INSPECTION OF THE TURBINE SECTION.  FULL INSPECTION OF THE COMPRESSOR, BLEED VALVE, AND RELATED SYSTEM WERE CONDUCTED, WITHOUT SUCCESS.  INSPECTION OF THE HOT END WAS CONDUCTED AND DISCOVERY OF BROKEN TURBINE BLADES WAS DISCOVERED.  ENGINE WAS REMOVED AND SHIPPED TO ACRO FOR INSPECTION.  (X)
