Final rule.

We are superseding airworthiness directive (AD) 2008-14- 16 for certain 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. AD 2008-14-16 required installing warning placards on the inside of the passenger door and service doors and modifying the hinge supports and support struts of the passenger doors. This new AD continues to require the actions required by AD 2008-14-16 and also requires replacing the fasteners which were installed as part of the modification with new fasteners of the correct length, adds new airplanes, and removes one airplane. This AD was prompted by reports that certain fasteners, which were installed as part of the modification, are the wrong length. We are issuing this AD to prevent incidents of inadvertent opening and possible detachment of a passenger door in-flight, resulting in damage to airframe and systems and loss of control of the airplane.
