What was found
CREW NOTED THAT THE NR 1 ENGINE POWER LEVER AND CONDITION LEVER WERE BINDING DURING THEIR MORNING CHECKS. THE PRIOR DAY, THE SAME CREW NOTICED A "HIGH FREQUENCY VIBRATION" IN THE CONDITION LEVER PRIOR TO SHUT DOWN. UPON FURTHER INVESTIGATION IT WAS DETERMINED THE (FCU) FUEL CONTROL UNIT WAS FAULTY. MANUFACTURER ADDESSED THE PROBLEM WHERE IT TALKS ABOUT FCU'S BINDING AFTER BEING SUBJECTED TO ABNORMAL VIBRATIONAL STRESS. IN ADDITION TO REPLACING THE FCU, MANUFACTURER RECOMMENDED REPLACEMENT OF THE STARTER GENERATOR, WHICH IS WHERE THE VIBRATION TYPICALLY EMANATES FROM.
