## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dornier Model 328-100 series airplanes. This proposal would require a one-time check of the clearance between certain braces that connect the wings to the fuselage and the frame to which the top fairing is attached; and modification of the frame's Z-profile if the clearance is insufficient to prevent the braces from coming in contact with the frame. In addition, the proposed AD would require a one-time check of these braces to detect damage or wear; and repair, if necessary. This proposal is prompted by a report indicating that insufficient clearance between these braces and the frame could result in wear and consequent breaking of the braces. The actions specified by the proposed AD are intended to prevent failure of these braces, which could result in unstable movement of the wings in relation to the fuselage and adversely affect the aerodynamic characteristics of the wings.
