## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires replacement of a flight attendant panel and modification of its associated wiring. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the disabling of the ``Fasten Seat Belt'' and ``No Smoking'' signs when they are required to be illuminated. Such disabling could result in the inability to instruct the passengers to extinguish their cigarettes and fasten their seat belts when required, which may contribute to passenger injury should a hard landing or in-flight turbulence be experienced.
