## Discrepancy

PILOT WAS IN CRUISE FLIGHT AND EXPERIENCED A PARTIAL POWER LOSS AND THEN OIL PRESSURE LOSS OF THE RIGHT ENGINE.  PILOT SHUT DOWN ENGINE AND LANDED WITHOUT FURTHER INCIDENT.  UPON INSPECTION OF ENGINE IT WAS FOUND THAT THE SHAFT WAS BROKEN AND BOTHER TURBINE AND COMPRESSOR BLADES WERE DAMAGED.  TURBO WAS A RECENT INSTALL AFTER OVERHAUL BY ATC AND HAD 87.9 HOURS TSO.  MECHANICS VERIFIED THAT THE TURBO WAS PRE-OILED PRIOR TO RETURN TO SERVICE AND NO ISSUES WERE REPORTED POST-INSTALL.
