## Discrepancy

DURING CLIMB THROUGH FLIGHT LEVEL 200, THREE LOUD BANGS OCCURRED THAT JOLTED THE AIRCRAFT. THE AIRPLANE SEEMED TO YAW EACH TIME. NO ABNORMAL ENGINE INDICATIONS WERE OBSERVED. THE AIRPLANE WAS REMOVED FROM SERVICE AND THE LEFT ENGINE'S VARIABLE STATOR VANE SYSTEM WAS OUT OF ADJUSTMENT. THE VARIABLE STATOR VANE CABLE WAS REPLACED AND THE VARIABLE STATOR VANE SYSTEM WAS ADJUSTED.
