A method of repairing a casing for a gas turbine engine, wherein the casing has a wall extending generally axially, and between at least one radially extending flange, the radially extending flange being formed with a plurality of bolt holes, includes the steps of removing a portion of the flange including at least one bolt hole. The removed portion is associated with a defect and a remaining portion of the flange includes at least one non-removed bolt hole. A replacement portion is obtained to replace the removed portion. The replacement portion is secured in an opening left in the flange by the removed portion. A repaired gas turbine engine casing is also disclosed.
