## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA--Groupe AEROSPATIALE (Socata) Models TB9 and TB10 airplanes. This AD requires repetitively inspecting the wing front attachments on the wing and fuselage sides for cracks, and repetitively incorporating a certain modification kit (type of kit and time of incorporation depends on whether cracks are found during the inspection). This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent structural failure of the wing front attachments caused by fatigue cracking, which could result in the wing separating from the airplane if the airplane is operated with cracked wing front attachments over an extended period of time.
