## Discrepancy

THE AIRCRAFT EXPERIENCED VIBRATIONS AND AMP FLUCTUATIONS.  THE PROBLEM WAS ISOLATED TO THE RIGHT GENERATOR.  GENERATOR REMOVAL REVEALED BEARING FAILURE.  THIS WAS THE SECOND FAILURE WITHIN 200 FLIGHT HOURS OF OVERHAUL.  THE LEFT GENERATOR, S/N 2400, HAD THE IDENTICAL PROBLEM TWICE WITHIN 600 FLIGHT HOURS OF OVERHAUL.
