This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a change to the airworthiness limitations because of a design change by the manufacturer to the fuselage strut pick up ribs No. 5 and 6. The FAA is issuing this AD to require a revision of the airplane service manuals and incorporate new airworthiness limitations. Please call or email LGM if there are any questions concerning this AD. Thanks.
