Airworthiness Directives; Airbus Model A320 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires replacement of the existing mounting rack for the Digital Flight Data Recorder (DFDR) with a new rack having improved damping, and installation of a new bracket for re-routing the wiring harness. 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 possible loss of data recorded on the DFDR as a result of vibrations and/or accelerations during flight.
