## Discrepancy

DURING TAKEOFF, THE LEFT PROP WAS FLUCTUATING.  REMOVED SPINNER, BETA CAP, AND TUBE.  FOUND FLAT SPOT ON INNER O-RING. REPLACED BOTH O-RINGS.  SET BLADE ANGLE AND REINSTALLED PROP CAP AND SPINNER.  GROUND RAN THE NR ONE AND NR TWO ENGINES.  CHECKED BLADE ANGLE AND FLIGHT IDLE FUEL FLOWS.  OPERATIONALLY CHECKS GOOD.
