Airworthiness Directive · Amendment 39-12724 · Airbus Model A319, A320, A321, A330, and A340 Series Airplanes Equipped With Certain Thales Avionics Digital Distance and Radio Magnetic Indicators (DDRMIs)
Airbus Model A319, A320, A321, A330, and A340 Series Airplanes Equipped With Certain Thales Avionics Digital Distance and Radio Magnetic Indicators (DDRMIs)
Model A319, A320, and A321 series airplanes equipped with Thales Avionics Digital Distance and Radio Magnetic Indicators (DDRMIs) having part numbers specified in paragraph 3.2 of Airbus All Operator Telex (AOT) A320-34A1262, dated March 19, 2002; Model A330 series airplanes equipped with Thales Avionics DDRMIs having part numbers specified in paragraph 3.2 of Airbus AOT A330-34A3109, dated March 19, 2002; and Model A340 series airplanes equipped with Thales Avionics DDRMIs having part numbers specified in paragraph 3.2 of Airbus AOT A340-34A4120, dated March 19, 2002.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2002-06-53 that was sent previously to all known U.S. owners and operators of Airbus Model A319, A320, A321, A330, and A340 series airplanes equipped with certain Thales Avionics Digital Distance and Radio Magnetic Indicators (DDRMIs) by individual notices. This AD requires deactivation of certain Thales Avionics DDRMIs. This action 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 failure of the DDRMI, which could cause the loss of data from the affected computers to other systems and degradation or total failure of the computers, leading to reduced ability to control the airplane in adverse conditions.
