## Discrepancy

DURING CRUISE, CREW REPORTED “GEN FAIL R”. APPROXIMATELY 5-10 MINUTES LATER, IT WAS FOLLOWED BY “OIL LEVEL LOW R”. ABOUT 5 MINUTES LATER, THE CAPTAIN NOTICED THE OIL PRESSURE AND ITT START TO MOVE SO HE IMMEDIATELY SHUT THE ENGINE DOWN IN FLIGHT TO PREVENT FURTHER DAMAGE. AIRCRAFT DIVERTED TO SRM AND LANDED SAFELY WITHOUT INCIDENT. INITIAL INSPECTION FOUND RH DC GENERATOR SUFFERED CATASTROPHIC FAILURE.
