Zusammenfassung:	The present disclosure refers to a method for repairing a blade (10) connection of a generator rotor (16) comprising an internally threaded hole (17) formed in the generator rotor (16) and an externally threaded blade root (14). The method comprising the steps of removing the blade (10) from the generator rotor (16), removing material of a first section (11) of the root (14) extending from an end of the root (14) closest to the airfoil (15), and screwing the blade (10) back into the threaded hole (17). Besides the method a reworked blade (10) and a reworked blade generator rotor (16) connection is disclosed.
