Airworthiness Directive · Amendment 39-16920 · Flight controls
328 Support Services GmbH Airplanes
This AD applies to 328 Support Services GmbH (Type Certificate Previously Held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 airplanes; certificated in any category; all serial numbers.
We are adopting a new airworthiness directive (AD) for all 328 Support Services GmbH (Type Certificate previously held by AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Model 328-100 and 328-300 airplanes. This AD was prompted by a manufacturer safety analyses review on flight control which resulted in recommendations for reduced repetitive inspection intervals for the flight controls certification maintenance requirements (CMR) of the tab-to-actuator linkage. This AD requires revising the airplane maintenance program by incorporating certain CMR tasks. We are issuing this AD to prevent failure of these components or their constituent parts which could lead to reduced control 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 100 flight hours after the effective date of this AD: Revise the airplane maintenance program by incorporating the applicable CMR tasks identified in table 1 of this AD.

The initial compliance time for the CMR tasks identified in table 1 of this AD is within 500 flight hours after the most recent inspection, or within 100 flight hours after the effective date of this AD, whichever occurs later.
After accomplishing the revision required by paragraph (g) of this AD, no alternative inspection or inspection interval may be used unless the inspection or inspection interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD.
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.
