Abstract: The present disclosure is directed to a system and method for preventing damage to one or more components of the gas turbine engine during a repair procedure. The method includes locating one or more gaps of one or more components of the gas turbine engine in the vicinity of the defect. Further, the method includes filling the one or more gaps with a filler material so as to prevent arcing over the gaps during repair. Thus, the method also includes applying an electrical discharge to the defect.
