AD NUMBER: 2005-10-06
MANUFACTURER: AvCraft Aerospace GmbH SUBJECT: Airworthiness Directive 2005-10-06 SUMMARY: 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.
