(d) This AD was prompted by data showing that the magnetic variation table installed in the Honeywell inertial reference system (IRS) is obsolete at certain airports.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 magnetic and IRS deviations.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This AD requires revising the airplane flight manual (AFM) to prohibit operators from performing CAT 2 or CAT 3 automatic landings or roll- outs at certain airports. This AD also provides for an optional terminating action for the AFM revision. This AD is prompted by data showing that the magnetic variation table installed in the Honeywell inertial reference system (IRS) is obsolete at certain airports.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 magnetic and IRS deviations.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after the effective date of this AD: Revise the Limitations Section of the Airbus A318/319/320/321 AFM to prohibit operators from performing CAT 2 or CAT 3 automatic landings or roll-outs at certain airports by incorporating Airbus Temporary Revision (TR) 2.05.00/52, dated June 13, 2003, into the AFM, and operate the airplane in accordance with those limitations.
(g) When the information in Airbus TR 2.05.00/52, dated June 13, 2003, has been incorporated into the general revisions of the AFM, the general revisions may be inserted into the AFM, and the TR may be removed from the AFM.
Replacement of Honeywell ADIRUs having a P/N listed in Table 1 of this AD with new ADIRUs having new P/Ns, by doing all the actions using the Accomplishment Instructions of Airbus Service Bulletin A320-34-1231, Revision 02, dated October 10, 2002 (for Model A320 series airplanes); A320-34-1240, Revision 01, dated October 10, 2001 (for Model A319, A320, and A321 series airplanes); or A320-34-1249, dated June 25, 2001 (for Model A319, A320, and A321 series airplanes); as applicable; terminates the AFM revision required by paragraph (f) of this AD. Following accomplishment of the replacement, the TR may be removed from the AFM.
(i) Prior to or concurrently with accomplishment of the optional terminating action in paragraph (h) of this AD: Do the replacements using Airbus Service Bulletin A320-34-1084, dated September 15, 1994 (for Model A320 series airplanes); A320-34-1129, Revision 01, dated July 22, 1997 (for Model A319, A320, and A321 series airplanes); or A320-34-1136, dated June 5, 1997 (for Model A319, A320, and A321 series airplanes); as applicable.
(j) Prior to or concurrently with accomplishment of Airbus Service Bulletin A320-34-1084: Do the modification of certain ADIRU equipment using Airbus Service Bulletin A320-34-1010, dated September 6, 1989 (for Model A320 series airplanes).
(k) Honeywell Service Bulletins HG1150AC-34-0007, Revision 001, dated September 18, 2001; HG2030AC-34-0009, Revision 1, dated October 1, 2002; and HG2030AD-34-0007, Revision 1, dated June 4, 2001; are referenced in the Airbus service bulletins specified in paragraph (h) of this AD as additional sources of service information for accomplishment of the replacement of the ADIRUs.
