## Summary

This document revises an earlier proposed airworthiness directive (AD), applicable to certain Dornier Model 328-300 series airplanes, that would have required performing a check of the airplane maintenance records; inspecting the engine nacelle anti-ice tube for leaks, if necessary; and modifying the joint, if necessary. This new action revises the proposed rule by removing the requirement to perform a records check, which was intended to allow operators to determine whether the inspection would be required. The actions specified by this new proposed AD are intended to prevent an uncommanded engine shutdown in a critical phase of flight due to leakage of air from a loose clamp on the anti-ice tubing joint. This action is intended to address the identified unsafe condition.
