Zusammenfassung:	A method for repairing a blade in a gas turbine engine comprises the steps of: isolating the damage on the airfoil of the blade; forming a cut back in the shape of elongated "D" shaped recess with a pair of fillets, a depth and a longitudinal axis of the "D" shaped recess having a length along the leading or trailing edge of the airfoil; and the fillets having a respective radius. Une méthode de réparation dune pale dans une turbine à gaz comprend les étapes suivantes : isoler les dommages sur la surface portante de la pale; découper une cavité en « D » allongé à laide dune paire de Karman, une profondeur et un axe longitudinal de la cavité en D ayant une longueur le long du bord dattaque ou de fuit de la surface portante, et les Karman ayant un rayon spécifique.
