## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA--Groupe AEROSPATIALE (Socata) Models TB9, TB10, and TB200 airplanes. This AD requires inspecting the main landing gear (MLG) support ribs for cracks, replacing MLG support ribs that have cracks beyond a certain level, and incorporating a certain MLG support rib reinforcement kit. 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 MLG failure caused by cracks in the support ribs, which could result in loss of control of the airplane during landing operations.
