Airworthiness Directive · Amendment 39-10770 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
Model A319, A320, and A321 series airplanes; equipped with Monogram rinse valves having part number (P/N) 15800- 348, Revision C; and on which Airbus Modification 26145 (reference Airbus Service Bulletin A320-38-1049) has not been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires replacing certain toilet rinse valves with modified rinse valves. 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 water contamination of the avionics computers, which could result in the display of erroneous or misleading information to the flightcrew, and consequent reduced controllability of the airplane.
