## Discrepancy

CREW NOTICED A VIBRATION IN CRUISE.  IDENTIFIED ELECTRICAL POWER LOSS IN RT STARTER/GENERATOR. I SOLATED STARTER/GENERATOR.  NO FURTHER PROBLEMS EXPERIENCED DURING THE FLIGHT.  RESEARCH REVEALED THE STARTER/GENERATOR, O/H, HAD THE SAME FAILURE PRIOR TO BEING OVERHAULED.  BECAUSE OF THE CALENDAR TIME, IT WASN'T POSSIBLE TO TRACE THE COMPONENT HISTORY OF THE BEARINGS, VENDOR, ETC. STARTER/GENERATOR RETURNED FOR FURTHER EVALUATION.
