## Discrepancy

DURING TAKE OFF, THE LEFT ENGINE APPROACHED OVERTEMP AT APPROXIMATELY 85% WELL BELOW N1 OF THE DAY,  ABORTED THE TAKE OFF AND RETURNED TO BASE. THE ENGINE WAS TROUBLESHOT AND IT WAS FOUND THAT THE LEFT SIDE BLEED PORT BELLOWS WAS SEPARATED AND LEAKING. THE PARTS WERE REPLACED AND OPERATIONALLY CHECKED THEN RETURNED TO SERVICE.
