## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that currently requires repetitive tightening of the screws and quick-release fasteners on the wing/body fairing panels. This proposed action would continue to require the repetitive tightening of these parts on certain airplanes. The proposed AD also would require the installation of new fastener systems for those panels on certain airplanes and the application of new torque values. Accomplishment of these actions would terminate the requirement for repetitive tightening of the screws and fasteners of those airplanes. In addition, the proposed AD would limit the applicability of the existing AD by removing certain airplanes. This proposal is prompted by the manufacturer's development of new fastener systems that will not vibrate and loosen. The actions specified by the proposed AD are intended to prevent separation of loosened wing/body fairing panels from the airplane, which, if not corrected, could lead to structural damage to the horizontal or vertical stabilizer, and potential injury to persons on the ground.
