## Discrepancy

DURING ENGINE START PROCEDURE, RT ENGINE WOULD NOT START. INSPECTION OF RT ENGINE MAGNETOS, THE LT MAGNETO WAS FOUND TO BE HARD TO ROTATE DUE TO DRIVE END BEARING FAILURE.  NO OTHER DAMAGE WAS FOUND WITH MAGNETO.  STIFF / FROZEN BEARING WAS CAUSING IMPULSE COUPLING TO BE INEFFECTIVE.  A NEW MAGNETO WAS INSTALLED AND ACFT WAS RETURNED TO SERVICE.
