## Discrepancy

IN CRUISE FLIGHT, FROM KBUR TO KCRQ, PILOT EXPERIENCING LOUDER THAN NORMAL ENGINE NOISE AND VIBRATION, THE LEFT GENERATOR WENT OFFLINE. IT SHOWED 2 VOLTS, AND THE RIGHT GENERATOR SHOWED 29 VOLTS. PER THE CHECKLIST, PILOT RESET THE GENERATOR, AND IT SHOWED 29 VOLTS AGAIN AFTER THE RESET. CHECKLIST PROCEDURE SAID TO TURN IT BACK ON, PILOT DID. IT OPERATED NORMALLY UNTIL TOUCHDOWN AT KCRQ WHERE IT AGAIN WENT OFFLINE. TECHNICIANS ARE SCHEDULED TO PERFORM AT KCRQ STARTER GENERATOR REPLACEMENT AND ALL REQUIRED PROCEDURES BY WILLIAMS INTERNATIONAL.
