This AD results from a report indicating that the main landing gear (MLG) casings have received improper hydrogen embrittlement relief. We are issuing this AD to prevent a fracture of the MLG casings and a collapse of the affected MLG, which could adversely affect the airplane's continued safe flight and landing.
