## Discrepancy

DURING APPROACH WHEN THROTTLES WERE RETARDED THE RIGHT ENGINE FLAMED OUT, ENGINE WAS SECURED AND UNEVENTFUL LANDING ACCOMPLISHED.  UPON INVESTIGATION FOUND THE RIGHT ENGINE LOW PRESSURE COMPRESSOR/LOW PRESSURE TURBINE SECTION WOULD NOT ROTATE.  HIGH PRESSURE COMPRESSOR/TURBINE SECTION WAS ABLE TO BE ROTATED.  ACCOMPLISHED BORESCOPE INSPECTION, NO APPARENT INGESTION OR FAILURE IN COMPRESSOR SECTIONS WAS EVIDENT, NOR WERE THERE ANY ABNORMALITIES NOTED IN THE HP TURBINE SECTION.  DEBRIS WAS NOTED IN THE TAILPIPE, APPEARED TO BE PIECES OF THE LP TURBINE SECTION, ALSO NOTED THE LP2 TURBINE HAD BLADES DAMAGED AND DISLODGED.  CONDITION APPEARS TO BE CAUSED BY A FAILURE IN ONE OF THE LP TURBINES.  FURTHER INFORMATION WILL NOT BE AVAILABLE UNTIL ENGINE IS DISASSEMBLED.
