## Abstract

We are adopting a new airworthiness directive (AD) for SOCATA Model TB 9, TB 10, TB 20, TB 21, and TB 200 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion of the horizontal stabilizer. We are issuing this AD to require actions to address the unsafe condition on these products.
