Abstract
A method is provided for repairing a turbine engine including a stage of vanes, the stage of vanes including a first vane having a first shroud and a second vane having a second shroud. The method includes: inspecting the stage of vanes in situ, wherein inspecting the stage of vanes in situ includes determining an actual gap width of a gap defined between the first shroud of the first vane and the second shroud of the second vane is greater than a predetermined threshold; and installing a shim in situ in the gap between the first shroud and the second shroud.

A method for repairing a turbine engine comprising a stage of vanes, the stage of vanes including a first vane having a first shroud and a second vane having a second shroud, the method comprising:
- inspecting the stage of vanes in situ, wherein inspecting the stage of vanes in situ comprises determining an actual gap width of a gap defined between the first shroud of the first vane and the second shroud of the second vane is greater than a predetermined threshold;
- and
- installing a shim in situ in the gap between the first shroud and the second shroud.
A repair tool for a gas turbine engine comprising:
- a snake arm;
- and
- a base having the snake arm attached thereto, the base including one or more motors operably coupled to the snake arm and a controller, the controller operably coupled to the one or more motors and including one or more processors and memory, the memory storing data and instructions that when processed by the one or more processors cause the repair tool to perform functions, the functions including inspecting a stage of vanes of the gas turbine engine in situ, wherein
- inspecting the stage of vanes in situ comprises determining an actual gap width of a gap defined between a first shroud of a first vane in the stage of vanes and a second shroud of a second vane in the stage of vanes is greater than a predetermined threshold;
- and
- installing a shim in situ in the gap between the first shroud and the second shroud with the snake arm.
