The present invention provides a method for (i) repairing a structural weakness, or (ii) preventing or inhibiting the initiation of a structural weakness, or (iii) preventing or inhibiting the progression of a structural weakness in an aircraft frame element, the method comprising the step of bonding a plurality of particles to the element, the bonding being effected under conditions allowing the plurality of metallic particles to form a substantially continuous layer over the area of weakness, or the predicted area of weakness. The metallic particles may be deposited on the frame element by a cold spray process such as supersonic particle deposition. The structural weakness may be a stress corrosion crack in the aircraft frame element.
