Airbus Model A330 Airplanes and Model A340-200 and -300 Series Airplanes
This AD applies to Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes, certificated in any category; equipped with the air data inertial reference units (ADIRUs) identified in paragraphs (c)(1) and (c)(2) of this AD.
(1) Honeywell ADIRUs having part numbers (P/Ns) HG2030AC0X (where X is any number between 0 and 9 inclusive) and P/Ns HG2030ADYY (where YY is any number between 00 and 10 inclusive).
(2) Northrop Grumman (formerly Litton) ADIRUs having P/Ns 465020-030303ZZ (where ZZ is any number between 00 and 12 inclusive).
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and Model A340-200 and -300 series airplanes. This AD requires revising the airplane flight manual (AFM) to prohibit the flightcrew from performing CAT 2 and CAT 3 automatic landings and roll-outs at certain airports. This AD also provides an optional terminating action for the AFM revision. This AD results from data showing that the magnetic variation table installed in certain Honeywell and Northrop Grumman air data inertial reference units (ADIRUs) is obsolete at certain airports. We are issuing this AD to prevent the airplane from departing the runway during a CAT 2 or CAT 3 automatic landing or roll-out, due to differences between actual magnetic variation and the values in the ADIRU magnetic variation tables.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
The term “Temporary Revision,” as used in this AD, means the following TRs, as applicable:
(1) For Model A330-200 and A330-300 series airplanes equipped with any Honeywell ADIRU identified in paragraph (c)(1) of this AD: Airbus TR 2.05.00/67, Issue 2, dated September 19, 2007, to the Airbus A330 Airplane Flight Manual (AFM);
(2) For Model A330-200 and A330-300 series airplanes equipped with any Northrop Grumman ADIRU identified in paragraph (c)(2) of this AD: Airbus TR 2.05.00/68, dated March 31, 2006, to the Airbus A330 AFM;
(3) For Model A340-200 and A340-300 series airplanes equipped with any Honeywell ADIRU identified in paragraph (c)(1) of this AD: Airbus TR 2.05.00/87, Issue 2, dated September 19, 2007, to the Airbus A340 AFM; and
(4) For Model A340-200 and A340-300 series airplanes equipped with any Northrop Grumman ADIRU identified in paragraph (c)(2) of this AD: Airbus TR 2.05.00/88, dated March 31, 2006, to the Airbus A340 AFM.
Within 14 days after the effective date of this AD, revise the Limitations Section of the Airbus A330 or A340 AFM, as applicable, to prohibit the flightcrew from performing CAT 2 and CAT 3 automatic landings and roll-outs at certain airports by incorporating the applicable Temporary Revision into the AFM. Operate the airplane according to the limitations in the applicable TR.
(h) When the information in the applicable TR has been incorporated into the general revisions of the Airbus A330 or A340 AFM, as applicable, the general revisions may be inserted into the AFM, and the TR may be removed from the AFM.
(i) Replacing the ADIRUs with new, improved ADIRUs as specified in paragraph (i)(1), (i)(2), (i)(3), or (i)(4) of this AD terminates the AFM revision required by paragraph (g) of this AD.
(1) For Model A330-200 and A330-300 series airplanes equipped with any Honeywell ADIRU identified in paragraph (c)(1) of this AD, doing the replacement in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-34-3104, dated July 17, 2003; or Airbus Service Bulletin A330-34-3165, dated June 28, 2006.
(2) For Model A330-200 and A330-300 series airplanes equipped with any Northrop Grumman ADIRU identified in paragraph (c)(2) of this AD, doing the replacement in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-34-3132, dated December 16, 2003, or Revision 01, dated August 18, 2004; Airbus Service Bulletin A330-34-3159, dated February 10, 2005; or Airbus Service Bulletin A330-34-3183, dated June 16, 2006.
(3) For Model A340-200 and A340-300 series airplanes equipped with any Honeywell ADIRU identified in paragraph (c)(1) of this AD, doing the replacement in accordance with the Accomplishment Instructions of Airbus Service Bulletin A340-34-4114, dated July 17, 2003; or Airbus Service Bulletin A340-34-4166, dated June 28, 2006.
(4) For Model A340-200 and A340-300 series airplanes equipped with any Northrop Grumman ADIRU identified in paragraph (c)(2) of this AD, doing the replacement in accordance with the Accomplishment Instructions of Airbus Service Bulletin A340-34-4141, dated December 16, 2003, or Revision 01, dated August 18, 2004; Airbus Service Bulletin A340-34-4163, dated February 10, 2005; or Airbus Service Bulletin A340-34-4173, dated June 16, 2006.
