AD NUMBER: 2005-10-02 MANUFACTURER: AvCraft Aerospace GmbH SUBJECT: Airworthiness Directive 2005-10-02 SUMMARY: 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.
