Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus SAS Model A321-111, A321-112, A321-131, A321-211, A321-
212, A321-213, A321-231 and A321-232 airplanes. This proposed AD was 
prompted by a quality control review, which determined that the wrong 
aluminum alloy was used to manufacture several structural parts. This 
proposed AD would require a one-time eddy current conductivity 
measurement of certain structural parts of the outer flaps to determine 
if the incorrect alloy was used, and replacement if necessary, as 
specified in an European Aviation Safety Agency (EASA) AD, which will 
be incorporated by reference. The FAA is proposing this AD to address 
the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by July 22, 
2019.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0012, dated January 24, 2019 
(``EASA AD 2019-0012'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A321-111, A321-112, A321-131, A321-
211, A321-212, A321-213, A321-231 and A321-232 airplanes. The MCAI 
states:

    Following a quality control review on the Airbus final assembly 
line, it was discovered that wrong aluminum alloy was delivered by a 
supplier for several structural parts. The results of the 
investigations highlighted that part of the stock could be impacted 
by this wrong material. Prompted by this finding, EASA published AD 
2015-0218 [which corresponds to FAA AD 2017-05-02 (82 FR 12407, 
March 3, 2017)], requiring an [special detailed inspection] SDI of 
certain cabin, cargo compartment and airframe parts. Subsequent 
investigation results established that outer flaps structure are 
also affected. Structural investigations demonstrated the capability 
to sustain the static limits loads, and sufficient fatigue life up 
to a certain inspection threshold.
    This condition, if not detected and corrected, could affect the 
structural integrity of the outer flap, possibly resulting in 
reduced control of the aeroplane.
    To address this potential unsafe condition, Airbus issued the 
inspection [service bulletin] SB to provide inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time SDI of suspected parts for material identification and, 
depending on findings, replacement with serviceable parts.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0012 describes procedures for a one-time eddy current 
conductivity measurement of certain structural parts on the outer flaps 
to determine if an incorrect aluminum alloy was used, and replacement 
of any affected part with a serviceable part. 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 and Requirements of This Proposed AD

    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 FAA has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the agency 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2019-0012, as incorporated by reference, except for any 
differences identified as exceptions in the regulatory text of this AD. 
This proposed AD also would require sending the inspection results to 
Airbus SAS.

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, 
the FAA expects that EASA AD 2019-0012 will be incorporated by 
reference in the FAA's final rule. This proposed AD would, therefore, 
require compliance with the provisions specified in EASA AD 2019-0012, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information specified in EASA AD 
2019-0012 that is required for compliance with EASA AD 2019-0012 will 
be available on the internet at http://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0400 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 29 airplanes 
of U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...........................              $0             $510          $14,790
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it would take about one work-hour per 
product to comply with the proposed reporting requirement in this 
proposed AD. The average labor rate is $85 per hour. Based on these 
figures, the FAA estimates the

[[Page 26600]]

cost of reporting the inspection results on U.S. operators to be 
$2,465, or $85 per product.
    The FAA has received no definitive data that would enable the 
agency to provide cost estimates for the on-condition actions specified 
in this proposed AD.
    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. The FAA does not control warranty 
coverage for affected individuals. As a result, the agency has included 
all known costs in the cost estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information proposed by this NPRM is 2120-
0056. The paperwork cost associated with this NPRM has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this NPRM would be mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the burden should be directed to 
the FAA at 800 Independence Ave. SW, Washington, DC 20591, ATTN: 
Information Collection Clearance Officer, AES-200.

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.
    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 proposed 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 proposed AD would not have 
federalism implications under Executive Order 13132. This proposed AD 
would 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 this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Will not affect intrastate aviation in Alaska; and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

serviceable parts as defined in EASA AD 2019-0012 are allowed to be 
installed on any airplane.
    (4) Where any service information referenced in EASA AD 2019-
0012 specifies reporting, this AD requires reporting all inspection 
results at the applicable time specified in paragraph (h)(4)(i) or 
(h)(4)(ii) of this AD. If operators have reported findings as part 
of obtaining any corrective actions approved by Airbus SAS's EASA 
Design Organization Approval (DOA), operators are not required to 
report those findings as specified in this paragraph.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) If the inspection was done before the effective date of 
this AD: Submit the report within 30 days after the effective date 
of this AD.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA,

[[Page 26601]]

has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Section, send it to the attention of 
the person identified in paragraph (j)(2) of this AD. Information 
may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or Airbus SAS's 
EASA DOA. If approved by the DOA, the approval must include the DOA-
authorized signature.
    (3) Required for Compliance (RC): For any service information 
referenced in EASA AD 2019-0012 that contains RC procedures and 
tests: Except as required by paragraphs (h)(4) and (i)(2) of this 
AD, RC procedures and tests must be done to comply with this AD; any 
procedures or tests that are not identified as RC are recommended. 
Those procedures and tests that are not identified as RC may be 
deviated from using accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
    (4) Paperwork Reduction Act Burden Statement: A federal agency 
may not conduct or sponsor, and a person is not required to respond 
to, nor shall a person be subject to a penalty for failure to comply 
with a collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately one 
hour per response, including the time for reviewing instructions, 
completing and reviewing the collection of information. All 
responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing 
the burden should be directed to the FAA at: 800 Independence Ave.
