Airworthiness Directives; Airbus Model A319 and A320 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 certain Airbus Model A319 and A320 series airplanes. 
This action requires revising the Airplane Flight Manual to advise the 
flight crew of performance corrections necessary to ensure adequate 
runway lengths for certain takeoff and landing conditions. This action 
is necessary to prevent the airplane from departing the end of the 
runway during a landing or a rejected takeoff due to reduced braking 
performance.

DATES: Effective October 26, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of October 26, 2001.

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile 
(DGAC), which is the airworthiness authority for France, recently 
notified the FAA that an unsafe condition may exist on Airbus Model 
A319 and A320 series airplanes equipped with certain Goodrich carbon 
brakes. The DGAC advises that a Model A320 series airplane departed the 
end of the runway during landing. Investigation revealed that the 
airplane's Goodrich brakes did not meet performance specifications. The 
reduced performance may have been caused by the contamination of the 
brake wear surfaces by the oxidation inhibitor applied during 
production and/or a tendency of this particular type of oxidation 
inhibitor to absorb water. The susceptibility of this oxidation 
inhibitor to absorb water is exacerbated during a period of inactivity 
of the airplane brakes (that is, more than 7 sequential days without 
brake usage). Such reduced braking performance could exist throughout 
the life of the brakes and, if not corrected, could result in the 
airplane departing the end of the runway during landing or a rejected 
takeoff.

Explanation of Relevant Service Information

    Airbus has issued A319/320/321 Airplane Flight Manual (AFM) 
Temporary Revisions (TRs) 5.02.00/60 (for Model A319 series airplanes) 
and 5.03.00/21 (for Model A320 series airplanes), both Issue 2, both 
dated September 14, 2001. The TRs provide the flight crew with 
performance corrections necessary to ensure adequate runway lengths for 
certain takeoff and landing conditions. The performance corrections are 
intended to prevent the airplane from departing the end of the runway 
during a landing or a rejected takeoff due to reduced braking 
performance. The DGAC classified these TRs as mandatory and issued 
French airworthiness directive 2001-441(B), dated September 19, 2001, 
to ensure the continued airworthiness of these airplanes in France.

FAA's Conclusions

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 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 the FAA informed 
of the situation described above. The FAA has 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 ensure adequate 
takeoff and landing field lengths to prevent the airplane from 
departing the end of the runway during a landing or a rejected takeoff 
due to reduced braking performance. This AD requires a revision to the 
Limitations section of the FAA-approved AFM to advise the flight crew 
of performance corrections necessary to ensure adequate runway lengths 
for certain takeoff and landing conditions.

Difference Between This AD and French Airworthiness Directive

    The applicability of this AD includes additional part numbers and 
modifications not identified by the existing French airworthiness 
directive. Those additional part numbers and modifications are included 
in Issue 2 of TRs 5.02.00/60 and 5.03.00/21, cited in this AD as the 
appropriate sources of information for the revised AFM procedures.

Interim Action

    This is considered to be interim action until final action is 
identified, at which time the FAA may consider further rulemaking.

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

[[Page 51861]]

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:
    <bullet> 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.
    <bullet> For each issue, state what specific change to the AD is 
being requested.
    <bullet> 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 2001-NM-287-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.
    The FAA has 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.
