Airworthiness Directives; Airbus Model A321 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
is applicable to all Airbus Model A321 series airplanes. This action
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 action is necessary to prevent roll
oscillations during approach and landing in certain icing, crosswind,
and turbulent conditions, which could result in reduced controllability
of the airplane. This action is intended to address the identified
unsafe condition.
DATES: Effective February 18, 2004. Comments for inclusion in the Rules
Docket must be received on or before March 4, 2004.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-114,
Attention: Rules Docket No. 2003-NM-257-AD, 1601 Lind Avenue, SW.,
Renton, Washington 98055-4056. Comments may be inspected at this
location between 9 a.m. and 3 p.m., Monday through Friday, except
Federal holidays. Comments may be submitted via fax to (425) 227-1232.

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile
(DGAC), which is the airworthiness authority for France, notified the
FAA that an unsafe condition may exist on all Airbus Model A321 series
airplanes. The DGAC advises that pilots of two separate Model A321
series airplanes encountered some lateral handling difficulties, which
led to roll oscillations. These difficulties occurred when the pilots
were performing manual approaches using flaps full in moderate icing
conditions. External inspections of the affected airplanes revealed ice
on the parts of the wing and horizontal stabilizer that do not have
thermal anti-ice capability. The DGAC also advises that some operators
reported roll oscillations during manual approach in crosswind or in
moderate to severe turbulence. Roll oscillations during approach and
landing in certain icing, crosswind, and turbulent conditions, could
result in reduced controllability of the airplane.
The DGAC issued French airworthiness directive 2003-388(B), dated
October 15, 2003, to ensure the continued airworthiness of these
airplanes in France.
FAA's Conclusions
This airplane model is manufactured in France and is type
certificated for operation in the United States under the provisions of
Sec. 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept us informed of the
situation described above. We have examined the findings of the DGAC,
reviewed all available information, and determined that AD action is
necessary for products of this type design that are certificated for
operation in the United States.
Explanation of Requirements of Rule
Since an unsafe condition has been identified that is likely to
exist or develop on other airplanes of the same type design registered
in the United States, this AD is being issued to prevent roll
oscillations, which could result in reduced controllability of the
airplane. This AD requires revising the Limitations section of the
airplane flight manual (AFM) to include an instruction to use Flap 3
for landing when performing a manual approach in conditions of moderate
to severe icing, significant crosswind (i.e., crosswinds greater than
20 knots, gust included), or moderate to severe turbulence.
Determination of Rule's Effective Date
Since a situation exists that requires the immediate adoption of
this regulation, it is found that notice and opportunity for prior
public comment hereon are impracticable, and that good cause exists for
making this amendment effective in less than 30 days.
Comments Invited
Although this action is in the form of a final rule that involves
requirements affecting flight safety and, thus, was not preceded by
notice and an opportunity for public comment, comments are invited on
this rule. Interested persons are invited to comment on this rule by
submitting such written data, views, or arguments as they may desire.
Communications shall identify the Rules Docket number and be submitted
in triplicate to the address specified under the caption ADDRESSES. All
communications received on or before the closing date for comments will
be considered, and this rule may be amended in light of the comments
received. Factual information that supports the commenter's ideas and
suggestions is extremely helpful in evaluating the effectiveness of the
AD action and determining whether additional rulemaking action would be
needed.
Submit comments using the following format:
Organize comments issue-by-issue. For example,
discuss a request to change the compliance time and a request to change
the service bulletin reference as two separate issues.
For each issue, state what specific change to
the AD is being requested.
[[Page 5008]]
Include justification (e.g., reasons or data)
for each request.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify the rule. All comments submitted will be
available, both before and after the closing date for comments, in the
Rules Docket for examination by interested persons. A report that
summarizes each FAA-public contact concerned with the substance of this
AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their comments
submitted in response to this rule must submit a self-addressed,
stamped postcard on which the following statement is made: ``Comments
to Docket Number 2003-NM-257-AD.'' The postcard will be date stamped
and returned to the commenter.
Regulatory Impact
The regulations adopted herein will not have a substantial direct
effect on the States, on the relationship between the national
Government and the States, or on the distribution of power and
responsibilities among the various levels of government. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
We have determined that this regulation is an emergency regulation
that must be issued immediately to correct an unsafe condition in
aircraft, and that it is not a ``significant regulatory action'' under
Executive Order 12866. It has been determined further that this action
involves an emergency regulation under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979). If it is determined that
this emergency regulation otherwise would be significant under DOT
Regulatory Policies and Procedures, a final regulatory evaluation will
be prepared and placed in the Rules Docket. A copy of it, if filed, may
be obtained from the Rules Docket at the location provided under the
caption ADDRESSES.
