## Discrepancy

WHILE IN CRUISE FLIGHT FROM KBCT TO KBVT AT FL410 THE FLIGHT HEARD A LOUD BANG FOLLOWED BY OSCILLATIONS ON THE ROLL AXIS.  AN EMERGENCY WAS DECLARED AND THE AIRCRAFT WAS LANDED AT KLACY WITH NO FURTHER PROBLEMS.  REPLACED RT ENGINE BLEED ACTUATOR VALVE PER PWC JT15D-5 MM 72-30-00.  OPS CHECK GOOD.  TEST FLIGHT WAS SATISFACTORY.
