Airworthiness Directive · Amendment 39-10279 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Model A320 series airplanes on which Airbus Modification 21574 (Airbus Service Bulletin A320-32-1139, Revision 1, dated December 30, 1994) or 21999 has not been installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires replacement of a capacitor of the main landing gear (MLG) circuitry with a new electrolytic capacitor having a tantalum casing. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the failure of the landing gear to retract properly as a result of failure of a capacitor in the MLG circuitry and subsequent power interruption.
