[Docket No. FAA–2005–20755; Directorate
Identifier 2004–NM–244–AD; Amendment
39–14176; AD 2005–13–39]
RIN 2120–AA64
Airworthiness Directives; Airbus Model
A321–100 and –200 Series Airplanes
AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: 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.
DATES: This AD becomes effective
August 9, 2005.
The incorporation by reference of
certain publications listed in the AD is
approved by the Director of the Federal
Register as of August 9, 2005.
ADDRESSES: For service information
identified in this AD, contact Airbus, 1
Rond Point Maurice Bellonte, 31707
Blagnac Cedex, France.
Docket: The AD docket contains the
proposed AD, comments, and any final
disposition. You can examine the AD
docket on the Internet at http://
dms.dot.gov, or in person at the Docket
Management Facility office between 9
a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The
Docket Management Facility office
(telephone (800) 647–5227) is located on
the plaza level of the Nassif Building at
the U.S. Department of Transportation,
400 Seventh Street, SW., room PL–401,
Washington, DC. This docket number is
FAA–2005–20755; the directorate
identifier for this docket is 2004–NM–
244–AD.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 with
an AD to supersede AD 2004–03–02,
amendment 39–13446 (69 FR 5007,
February 3, 2004). The existing AD
applies to all Airbus Model A321 series
airplanes. The proposed AD was
published in the Federal Register on
March 30, 2005 (70 FR 16167), to
require revising the airplane flight
manual (AFM) to specify procedures for
landing under certain conditions of
icing, significant crosswind, or
moderate to severe turbulence, until the
new requirements of this new AD have
been accomplished. That action also
proposed to require replacing existing
elevator and aileron computers (ELACs)
with ELACs having either L83 or L91
software, as applicable, which would
terminate the requirements of the
existing AD. That action also proposed
to require a related concurrent action. In
addition, that action also proposed to
revise the applicability by removing
airplanes with these ELAC software
standards incorporated in production.
