Abstract: A repair tool for applying a coating patch includes a heating element, a flexible bladder disposed adjacent the heating element, and an inflexible shell disposed about the flexible bladder. The inflexible shell defines a negative space corresponding to a plurality of sides of an aircraft component. A controller is communicatively coupled to the heating element and the bladder, and is configured to control a temperature of the heating element and a pressure of the flexible bladder.

Abstract: A method comprises the steps of providing a tool over a collar secured to a stud on a gas turbine engine system. The collet is driven to rotate and remove the collar from the stud. A tool for removing collars from studs has a driver with a housing receiving a piston. A spring drives the piston, and the housing also has a hydraulic fluid supply opening for selectively receiving a hydraulic fluid to move the piston in opposition to a force from the spring. Collet fingers are movable between a released position and a secured position when a supply of hydraulic fluid is supplied into the housing.
