Airworthiness Directive · Amendment 39-14083 · Dornier Model 328-300 Series Airplanes
Dornier Model 328-300 Series Airplanes
This AD applies to Dornier Model 328-300 series airplanes, serial numbers 3105 through 3219 inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Dornier Model 328-300 series airplanes. This AD requires installing a drain hole in the lower skin of the left- and right-hand elevator horns. This AD is prompted by reports of water found in the elevator assembly. We are issuing this AD to prevent water or ice accumulating in the elevator assembly, which could result in possible corrosion that reduces the structural integrity of the flight control surface, or in an unbalanced flight control surface. These conditions could result in reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 90 days after the effective date of this AD, install a drain hole in the lower skin of the left- and right-hand elevator horns in accordance with the Accomplishment Instructions of Dornier Service Bulletin SB-328J-55-203, Revision 1, dated November 19, 2003.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
