Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-145 series airplanes. This proposal would require the installation of reinforcements in the lower portion of wing rib 15 on the left-hand and right-hand sides of the airplane. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent reduced structural integrity of the wing flap support structure.
