ABSTRACT:
A method of repairing turbine blades where it is required to repair a blade while it is in situ on a rotor involves the movement of a lacing wire out of engagement with the blade to be repaired so that the blade may be repaired. The lacing wire may be completely removed from the array and replaced, or a new lacing wire member inseted by providing elongate holes or slots in the blade to enable the lacing wire member or members to be inserted into the blade array.
