Airworthiness Directive · Amendment 39-14079 · Dornier Model 328-300 Series Airplanes
Dornier Model 328-300 Series Airplanes
This AD applies to all Dornier Model 328-300 series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Dornier Model 328-300 series airplanes. This AD requires installing an additional mounting angle for the respective de-icing pipes at rib 9 in the leading edge area of the left- and right-hand wings. This AD is prompted by chafed de-icing lines in the wing leading edge area. We are issuing this AD to prevent chafing of the de-icing lines, which could result in a reduction in functionality of the anti-ice system, and possibly reduced controllability and performance of the airplane in icing conditions.
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 an additional mounting angle at rib 9 in the leading edge area of the left- and right-hand wings in accordance with the Accomplishment Instructions of Dornier Service Bulletin SB-328J-30-190, dated July 16, 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.
