Abstract: A method for repairing a gas turbine engine component includes the steps of repairing one of a suction side or a pressure side of the component; repairing internal geometry of the component after one of the suction side or the pressure side of the component is repaired; and repairing the other of the suction side and the pressure side of the component after the internal geometry of the component is repaired, wherein a backing material is utilized to preserve the internal geometry of the component when the other of the suction side and the pressure side of the component is being repaired.
