13DV-7756 METHOD AND REPLACEMENT MEMBER FOR REPAIRING A GAS TURBINE ENGINE VANE ASSEMBLY ABSTRACT OF THE DISCLOSURE A gas turbine engine air cooled vane assembly which includes inner and outer platform members and an airfoil member therebetween is repaired by removing from the vane assembly a vane assembly segment comprising at least a portion of the leading edge wall, a portion of the airfoil body wall and a portion of at least one platform member connected with the leading edge wall. The vane assembly segment is removed along a preselected path which, during operation of the vane assembly in a gas turbine engine, experiences relatively low mechanical stresses. A replacement member of substantially the same type of material and of a size and shape which matches the removed vane assembly segment is placed into registry with the vane assembly and then metallurgically bonded to the vane assembly.
