14 CFR Part 39

[Docket No. FAA-2019-0607; Product Identifier 2019-NM-135-AD; Amendment 
39-19709; AD 2019-16-06]
RIN 2120-AA64


Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A320-251N and A320-271N airplanes. This AD was 
prompted by analysis and laboratory testing of the behavior of the 
flight control laws, which identified reduced efficiency of the angle 
of attack (AoA) protection that may result in excessive pitch attitude 
in certain configurations in combination with specific maneuvers 
commanded by the flight crew. This AD requires revising the existing 
airplane flight manual (AFM) to incorporate operational limitations, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is incorporated by reference. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD becomes effective September 4, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 4, 
2019.
    The FAA must receive comments on this AD by October 4, 2019.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0189, dated July 31, 2019 
(``EASA AD 2019-0189'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A320-251N and A320-271N airplanes. 
The MCAI states:

    Analysis and laboratory testing of the behaviour of the flight 
control laws of the A320neo identified a reduced efficiency of the 
angle of attack protection when the aeroplane is set in certain 
flight configurations and in combination with specific manoeuvres 
commanded by the flight crew, as described through Section 2 of 
Airbus Flight Operations Transmission 999.0059/19.
    This condition, although never encountered during operations, if 
not corrected, could lead to excessive pitch attitude, possibly 
resulting in increased flight crew workload.
    To address this potential unsafe condition, Airbus issued the 
AFM TR [temporary revision], limiting the centre of gravity

[[Page 43040]]

envelope, which prevents the aforementioned condition, and the 
Flight Operations Transmission 999.0059/19, providing aeroplane 
loading recommendations.
    For the reason described above, this [EASA] AD requires 
amendment of the applicable AFM by incorporating the applicable AFM 
TR.
    This [EASA] AD is considered to be an interim action and further 
AD action may follow.
    The potential unsafe condition addressed by this [EASA] AD and 
related required actions are different from those addressed by EASA 
AD 2019-0171R1 for A321neo aeroplanes.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0189 describes procedures for revising the existing 
AFM to incorporate operational limitations and updated procedures 
related to center of gravity.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the agency has been notified of the unsafe condition described in the 
MCAI referenced above. The FAA is issuing this AD because it has 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2019-0189 described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA worked with Airbus and EASA to develop a process to 
use certain EASA ADs as the primary source of information for 
compliance with requirements for corresponding FAA ADs. As a result, 
EASA AD 2019-0189 will be incorporated by reference in the FAA final 
rule. This AD, therefore, requires compliance with EASA AD 2019-0189 in 
its entirety, through that incorporation, except for any differences 
identified as exceptions in the regulatory text of this AD. Using 
common terms that are the same as the heading of a particular section 
in the EASA AD does not mean that operators need comply only with that 
section. For example, where the AD requirement refers to ``all required 
actions and compliance times,'' compliance with this AD requirement is 
not limited to the section titled ``Required Action(s) and Compliance 
Time(s)'' in the EASA AD. Service information specified in EASA AD 
2019-0189 that is required for compliance with EASA AD 2019-0189 will 
be available on the internet at http://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0607 after the FAA final rule is 
published.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C.) authorizes agencies to dispense with notice and comment 
procedures for rules when the agency, for ``good cause,'' finds that 
those procedures are ``impracticable, unnecessary, or contrary to the 
public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without seeking comment prior to the 
rulemaking. Similarly, Section 553(d) of the APA authorizes agencies to 
make rules effective in less than thirty days, upon a finding of good 
cause.
    As noted above and in EASA AD 2019-0189, these airplanes are 
subject to reduced efficiency of the AoA protection that may result in 
excessive pitch attitude in certain configurations in combination with 
specific maneuvers commanded by the flight crew resulting in reduced 
control of the airplane. The FAA considers the prevention of this 
unsafe condition to be an urgent safety issue. Accordingly, notice and 
opportunity for prior public comment are impracticable and contrary to 
the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the 
FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making 
this amendment effective in less than 30 days.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites you to send any written relevant data, 
views, or arguments about this AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2019-0607; 
Product Identifier 2019-NM-135-AD'' at the beginning of your comments. 
The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. The FAA will 
consider all comments received by the closing date and may amend this 
AD based on those comments.
    The FAA will post all comments received, without change, to http://www.regulations.gov, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this AD.

Costs of Compliance

    The FAA estimates that this AD affects 69 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.

[[Page 43041]]

    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: General requirements. 
Under that section, Congress charges the FAA with promoting safe flight 
of civil aircraft in air commerce by prescribing regulations for 
practices, methods, and procedures the Administrator finds necessary 
for safety in air commerce. This regulation is within the scope of that 
authority because it addresses an unsafe condition that is likely to 
exist or develop on products identified in this rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    The FAA has determined that this AD will not have federalism 
implications under Executive Order 13132. This AD 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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
