Airworthiness Directive · Amendment 39-14176 · Airbus Model A321-100 and -200 Series Airplanes
Airbus Model A321-100 and -200 Series Airplanes
Superseded. A later AD replaced this one: AD 2016-17-03. Comply with the one in force.
(c) This AD applies to Airbus Model A321-111, -112, -131, -211, and -231 airplanes; certificated in any category; except those with Airbus Modification 34043 installed in production.
(d) This AD was prompted by issuance of mandatory continuing airworthiness information by a civil airworthiness authority. We are issuing this AD to prevent roll oscillations during approach and landing in certain icing, crosswind, and turbulent conditions, which could result in reduced controllability of the airplane.
The FAA is superseding an existing airworthiness directive (AD), which applies to Airbus Model A321 series airplanes. That AD currently requires revising the Limitations section of the airplane flight manual to include an instruction to use Flap 3 for landing when performing an approach in conditions of moderate to severe icing, significant crosswind (i.e., crosswinds greater than 20 knots, gust included), or moderate to severe turbulence. This new AD requires replacing existing elevator and aileron computers (ELACs) with ELACs having either L83 or L91 software, as applicable, which terminates the requirements of the existing AD. This AD also requires a related concurrent action. In addition, this AD revises the applicability by removing airplanes with these ELAC software standards incorporated in production. This AD is prompted by issuance of mandatory continuing airworthiness information by a civil airworthiness authority. We are issuing this AD to prevent roll oscillations during approach and landing in certain icing, crosswind, and turbulent conditions, which could result in reduced controllability of the airplane.
(f) Within 10 days after February 18, 2004 (the effective date of AD 2004-03-02), revise the Limitations section of the airplane flight manual (AFM) to include the following statement. This may be done by inserting a copy of this AD into the AFM.
“ A321 Approach and Landing (Roll Control) When moderate to severe icing conditions, or significant crosswind (i.e., crosswinds greater than 20 knots, gust included), or moderate to severe turbulence are anticipated:
Use FLAP 3 for landing.”
Note 1: When a statement identical to that in paragraph (f) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
(g) Within 16 months after the effective date of this AD: Replace existing ELACs with ELACs having L83 software, by accomplishing all of the actions specified in the Accomplishment Instructions of Airbus Service Bulletin A320-27-1151, including Appendix 01, dated March 9, 2004; or with ELACs having L91 software, by accomplishing all of the actions specified in the Accomplishment Instructions of Airbus Service Bulletin A320-27-1152, including Appendix 01, dated June 4, 2004; as applicable. After accomplishing the ELAC replacements, remove the AFM revision required by paragraph (f) of this AD. Accomplishing the requirements of this paragraph terminates the requirements of paragraph (f) of this AD.
Note 2: Airbus Service Bulletin A320-27-1151 refers to Thales Service Bulletin 394512-27-026, dated March 5, 2004, as an additional source of service information for installing ELAC L83 software. Airbus Service Bulletin A320-27-1152 refers to Thales Service Bulletin 394512B-27-010, dated May 24, 2004, as an additional source of service information for installing ELAC L91 software.
(h) Prior to doing the requirements of paragraph (g) of this AD: Install ELACs having L81 software in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-27-1135, Revision 02, dated April 18, 2002.
(i) Installation of ELACs having L81 software in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-27-1135, dated June 29, 2001; or Service Bulletin A320-27-1135, Revision 01, dated August 31, 2001; is acceptable for compliance with the requirements of paragraph (h) of this AD.
(j) As of the effective date of this AD, no person may install on any airplane an ELAC, part number 3945122506, 3945123506, 3945128102, or 3945128103.
(k)(1) The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19.
(2) Alternative methods of compliance, approved previously in accordance with AD 2004-03-02, are approved as alternative methods of compliance with the corresponding requirements of this AD.
(l) French airworthiness directive F-2004-147, dated August 18, 2004, also addresses the subject of this AD.
(m) You must use the service information listed in Table 1 of this AD to perform the actions that are required by this AD, unless the AD specifies otherwise. The Director of the Federal Register approves the incorporation by reference of these documents in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
