Airworthiness Directives; Flugzeugwerke Altenrheim AG (FFA) Airplanes

We are adopting a new airworthiness directive (AD) for Flugzeugwerke Altenrheim AG (FFA) Models AS 202/15 ``BRAVO'', AS 202/ 18A ``BRAVO'', and AS 202/18A4 ``BRAVO'' airplanes. This AD results from 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 corrosion on the upper forward fuselage stringers. We are issuing this AD to require actions to address the unsafe condition on these products.
