Abstract: It is described a method for reconditioning a damaged thread (8) of a transmission (1) of a hover-capable aircraft; the damaged thread (8) being arranged inside a first hole (23a) of the transmission (1); wherein the method includes the following steps: i) centering a tool (20) on the first hole (23a); ii) inserting a first tool (25) inside the tool (20) centred on the first hole (23a) and removing the damaged thread (8) through the first tool (25); iii) inserting a second tool (26) inside the tool (20) and creating a new thread (16) inside the first hole (23a) having a diameter larger than the one of the damaged thread (8); iv) screwing an insert (61) having a thread inside the new thread (16), so that the insert (61) engages the first hole (23a) and defines a reconditioned thread (8?); and v) keeping the transmission (1) mounted on the hover-capable aircraft during steps i), ii), iii), iv).
