ABSTRACT:
A method for repairing a turbine engine airfoil having an environmental resistant coating on a outer wall surface includes selecting and masking a discrete portion of the airfoil outer wall surface to protect the coating on the selected discrete portion, thereby providing a masked outer wall surface and an unmasked outer wall surface. The coating is removed from the unmasked outer wall surface, the maskant is removed, and the airfoil is repaired.
