Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0068, dated March 27, 2019 (‘‘EASA AD 2019–0068’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus SAS Model A320– 251N and A321–253N airplanes. The MCAI states: Cracks have been reported on pylon block seals of aeroplanes in final assembly line. Investigation results identified a manufacturing issue, leading to lack of thickness of seal on the engines and, eventually, cracks on pylon block seals. Affected aeroplanes have also been identified. This condition, if not corrected, could reduce the firewall integrity function between the pylon and the nacelle. To address this potential unsafe condition, Airbus issued the SB [Airbus Service Bulletin A320–54–1040, dated April 20, 2018], providing replacement instructions. For the reasons described above, this [EASA] AD requires replacement of pylon block seals. Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0068 describes procedures for replacement of the pylon block seals. 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 E:\FR\FM\24JNP1.SGM 24JNP1 29422 Federal Register / Vol. 84, No. 121 / Monday, June 24, 2019 / Proposed Rules 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 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 2019–0068 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, the FAA expects that EASA AD 2019–0068 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with the provisions specified in EASA AD 2019– 0068, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in EASA AD 2019–0068 that is required for compliance with EASA AD 2019–0068 will be available on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2019–0443 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD would affect 9 airplanes of U.S. registry. The agency estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 .......................................................................................... $5,300 $5,470 $49,230 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. jbell on DSK3GLQ082PROD with PROPOSALS 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 VerDate Sep<11>2014 16:30 Jun 21, 2019 Jkt 247001 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. PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 Regulatory Findings The FAA 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. List of Subjects in 14 CFR Part 39 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ Airbus SAS: Docket No. FAA–2019–0443; Product Identifier 2019–NM–056–AD. (a) Comments Due Date The FAA must receive comments by August 8, 2019. (b) Affected ADs None. (c) Applicability This AD applies to Airbus SAS Model A320–251N and A321–253N airplanes, certificated in any category, as identified in European Aviation Safety Agency (EASA) AD 2019–0068, dated March 27, 2019 (‘‘EASA AD 2019–0068’’). (d) Subject Air Transport Association (ATA) of America Code 54, Nacelles/pylons. The Proposed Amendment (e) Reason This AD was prompted by reports of cracks on the pylon block seals. The FAA is issuing this AD to address cracks on pylon block seals, which could reduce the firewall integrity between the pylon and the nacelle. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: (f) Compliance Comply with this AD within the compliance times specified, unless already done. Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0068, dated March 27, 2019 
(``EASA AD 2019-0068'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A320-251N and A321-253N 
airplanes. The MCAI states:

    Cracks have been reported on pylon block seals of aeroplanes in 
final assembly line. Investigation results identified a 
manufacturing issue, leading to lack of thickness of seal on the 
engines and, eventually, cracks on pylon block seals. Affected 
aeroplanes have also been identified.
    This condition, if not corrected, could reduce the firewall 
integrity function between the pylon and the nacelle.
    To address this potential unsafe condition, Airbus issued the SB 
[Airbus Service Bulletin A320-54-1040, dated April 20, 2018], 
providing replacement instructions.
    For the reasons described above, this [EASA] AD requires 
replacement of pylon block seals.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0068 describes procedures for replacement of the pylon 
block seals. 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

[[Page 29422]]

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 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 2019-0068 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, 
the FAA expects that EASA AD 2019-0068 will be incorporated by 
reference in the FAA final rule. This proposed AD would, therefore, 
require compliance with the provisions specified in EASA AD 2019-0068, 
through that incorporation, except for any differences identified as 
exceptions in the regulatory text of this proposed AD. Service 
information specified in EASA AD 2019-0068 that is required for 
compliance with EASA AD 2019-0068 will be available on the internet at 
http://www.regulations.gov by searching for and locating Docket No. 
FAA-2019-0443 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 9 airplanes of 
U.S. registry. The agency 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
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...........................          $5,300           $5,470          $49,230
----------------------------------------------------------------------------------------------------------------

    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.

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 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus SAS: Docket No. FAA-2019-0443; Product Identifier 2019-NM-
056-AD.

(a) Comments Due Date

    The FAA must receive comments by August 8, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A320-251N and A321-253N 
airplanes, certificated in any category, as identified in European 
Aviation Safety Agency (EASA) AD 2019-0068, dated March 27, 2019 
(``EASA AD 2019-0068'').

(d) Subject

    Air Transport Association (ATA) of America Code 54, Nacelles/
pylons.

(e) Reason

    This AD was prompted by reports of cracks on the pylon block 
seals. The FAA is issuing this AD to address cracks on pylon block 
seals, which could reduce the firewall integrity between the pylon 
and the nacelle.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

[[Page 29423]]

(g) Requirements

    Except as specified in paragraphs (h) and (i) of this AD: Comply 
with all required actions and compliance times specified in, and in 
accordance with, EASA AD 2019-0068.

(h) Exceptions to EASA AD 2019-0068

    (1) For purposes of determining compliance with the requirements 
of this AD: Where EASA AD 2019-0068 refers to its effective date, 
this AD requires using the effective date of this AD.
    (2) Where EASA AD 2019-0068 specifies credit for actions 
``accomplished before the effective date of this AD in accordance 
with the instructions of the applicable Airplane Maintenance 
Manual,'' this AD provides credit for actions ``accomplished before 
the effective date of this AD in accordance with the instructions of 
an FAA-approved maintenance or inspection program.''
    (3) The ``Remarks'' section of EASA AD 2019-0068 does not apply 
to this AD.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2019-0068 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) 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, 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

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 Design Organization Approval (DOA). If approved by the DOA, the 
approval must include the DOA-authorized signature.
