Abstract
Methods and apparatus are provided for repairing a damaged area within a cored passage of a component. The method includes providing a repair tool that has a support portion, a leading portion extending from a first end of the support portion, and a trailing portion extending from a second end of the support portion. The leading portion of the repair tool is inserted into a first opening of the cored passage, and is threaded through the cored passage until the support portion is positioned at the damaged area within the cored passage. A restoration activity is performed on the damaged area as the support portion supports the cored passage proximate to the damaged area. Upon completion of the restoration activity, the repair tool is removed from the cored passage.
