摘要： The invention features a method for reconditioning a blade (10) of a gas turbine, which blade (10) comprises a blade airfoil (11), with a pressure side (14) and a suction side (15), which extends in the blade longitudinal direction between a platform (18) and a blade tip (17), has a leading edge (12) and a trailing edge (13), and is outwardly delimited by a pressure-side wall (14a) and a suction-side wall (15a) which converge at the trailing edge (13) of the blade airfoil (11), forming discharge openings (21) for cooling air which are arranged in a distributed manner along the trailing edge (13) between the walls (14a, 15a). A reconditioning with comparatively low cost is achieved by a cutout (20) being introduced into the pressure-side wall (14a) along the trailing edge (13), and starting from said trailing edge (13), in such a way that the trailing-side edge of the pressure-side wall (14a) is cut back compared with the trailing-side edge of the suction-side wall (15a).
