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 installation of a rubber strip and replacement of connection sheets and the seal retainer on the avionics compartment access door with new parts; and installation of drip pans and additional drain gutters on the avionics racks. 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 trickling of water into the avionics compartment, which could result in avionics computer and equipment malfunctions.
