Airbus Model A319, A320, and A321 Series Airplanes
Superseded. A later AD replaced this one: AD 2002-10-06. Comply with the one in force.
Model A319, A320, and A321 series airplanes; certificated in any category; equipped with Rockwell Collins radio altimeter LRA 700 having part number (P/N) 622-4542-020; excluding those on which Airbus Modification 26017 (Airbus Service Bulletin A320-31-1106) has been installed.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A319, A320, and A321 series airplanes. This action requires a revision to the Limitations and Normal Procedures Sections of the FAA-approved Airplane Flight Manual (AFM) to limit the use of the radio altimeter of the flight management guidance system (FMGS) during the approach phase of flight. This action also provides for an optional terminating modification, which, if accomplished, would terminate the requirement for the AFM revision. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent erroneous display of decision height information to the flight crew during final approach, which could result in an increased risk of collision with the terrain.
To prevent erroneous display of decision height information to the flight crew during final approach, which could result in an increased risk of collision with the terrain, accomplish the following:
(a) Within 10 days after the effective date of this AD, revise the Limitations and Normal Procedures Sections of the FAA-approved AFM by inserting a copy of Airbus Temporary Revision (TR) 2.05.00/43, dated September 16, 1999, into the AFM.
Note 2: When the Temporary Revision required by paragraph (a) of this AD has been incorporated into the general revisions of the AFM, the general revisions may be inserted into the AFM, provided that the information contained in the general revisions is identical to that specified in the Temporary Revision.
(b) In lieu of accomplishing the requirements of paragraph (a) of this AD, modify the flight warning computers, in accordance with Airbus Service Bulletin A320-31-1106, Revision 04, dated December 21, 1999. After accomplishment of the modification, the AFM temporary revision required by paragraph (a) of this AD may be removed from the AFM.
Note 3: Accomplishment of the modification specified by paragraph (b) of the AD, prior to the effective date of this AD, in accordance with Airbus Service Bulletin A320-31-1106, Revision 01, dated April 16, 1997; Revision 02, dated January 20, 1998; or Revision 03, dated July 9, 1999; is considered acceptable for compliance with the applicable actions specified in paragraph (b) of this AD.
