The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2019–0251; Product Identifier 2019–NM–057–AD] RIN 2120–AA64 Airworthiness Directives; Airbus SAS Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A320–251N and –271N airplanes; and A321–251N, –253N, –271N, and –272N airplanes. This proposed AD was prompted by a report that during a calibration check, some torqueing tools used on the final assembly line have been found out of tolerance. This proposed AD would require retorqueing each affected connection of sense and fire extinguishing lines within the pylon area to a correct torque value, as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by June 21, 2019.

Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0081, dated April 3, 2019 (‘‘EASA AD 2019–0081’’) (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 –271N airplanes; and A321–251N, –253N, –271N, and –272N airplanes. The MCAI states: During periodic calibration check, some torqueing tools used on the final assembly line have been found out-of-tolerance. The subsequent investigation determined that connections of sense and fire extinguishing lines within the pylon area have been undertorqued on a group of aeroplanes. This condition, if not corrected, could lead to leaks or disconnections of those lines, possibly resulting in reduced engine control and/or reduced safety margin in case of engine fire. To address this potential unsafe condition, Airbus issued the applicable SB [service bulletin], providing instructions to restore the correct torque value of those affected connections. For the reason described above, this [EASA] AD requires re-torqueing to the correct value the affected connections. Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0081 describes procedures for retorqueing each affected connection of sense and fire extinguishing lines within the pylon area to a correct torque value. 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, and it is publicly available through the EASA website. 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 our bilateral agreement with the State of Design Authority, we have been notified E:\FR\FM\07MYP1.SGM 07MYP1 19880 Federal Register / Vol. 84, No. 88 / Tuesday, May 7, 2019 / Proposed Rules 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 2019–0081 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with the provisions specified in EASA AD 2019–0081, through that incorporation, except for any differences of the unsafe condition described in the MCAI referenced above. We are proposing this AD because we 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 2019–0081, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. identified as exceptions in the regulatory text of this proposed AD. Service information specified in EASA AD 2019–0081 that is required for compliance with EASA AD 2019–0081 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2019– 0251 after the FAA final rule is published. Costs of Compliance We estimate that this proposed AD affects 15 airplanes of U.S. registry. We estimate 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 10 work-hours × $85 per hour = $850 ........................................................................................ $0 $850 $12,750 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. We are 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. 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. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska; and 4. 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 1.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus SAS Model A320-251N and -271N airplanes; and A321-251N, 
-253N, -271N, and -272N airplanes. This proposed AD was prompted by a 
report that during a calibration check, some torqueing tools used on 
the final assembly line have been found out of tolerance. This proposed 
AD would require retorqueing each affected connection of sense and fire 
extinguishing lines within the pylon area to a correct torque value, as 
specified in a European Aviation Safety Agency (EASA) AD, which will be 
incorporated by reference. We are proposing this AD to address the 
unsafe condition on these products.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0081, dated April 3, 2019 
(``EASA AD 2019-0081'') (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 -271N airplanes; 
and A321-251N, -253N, -271N, and -272N airplanes. The MCAI states:

    During periodic calibration check, some torqueing tools used on 
the final assembly line have been found out-of-tolerance. The 
subsequent investigation determined that connections of sense and 
fire extinguishing lines within the pylon area have been under-
torqued on a group of aeroplanes.
    This condition, if not corrected, could lead to leaks or 
disconnections of those lines, possibly resulting in reduced engine 
control and/or reduced safety margin in case of engine fire.
    To address this potential unsafe condition, Airbus issued the 
applicable SB [service bulletin], providing instructions to restore 
the correct torque value of those affected connections.
    For the reason described above, this [EASA] AD requires re-
torqueing to the correct value the affected connections.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0081 describes procedures for retorqueing each 
affected connection of sense and fire extinguishing lines within the 
pylon area to a correct torque value. 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, and it is publicly available through the EASA 
website.

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 our bilateral agreement with the State of Design Authority, we have 
been notified

[[Page 19880]]

of the unsafe condition described in the MCAI referenced above. We are 
proposing this AD because we 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 2019-0081, 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 2019-0081 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with the 
provisions specified in EASA AD 2019-0081, through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information specified in EASA AD 
2019-0081 that is required for compliance with EASA AD 2019-0081 will 
be available on the internet at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0251 after the FAA final rule is 
published.

Costs of Compliance

    We estimate that this proposed AD affects 15 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
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.
    We are 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

    We 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. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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-2019-0251; Product Identifier 2019-NM-
057-AD.

(a) Comments Due Date

    We must receive comments by June 21, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A320-251N and -271N 
airplanes; and A321-251N, -253N, -271N, and -272N airplanes; 
certificated in any category, as identified in European Aviation 
Safety Agency (EASA) AD 2019-0081, dated April 3, 2019 (``EASA AD 
2019-0081'').

(d) Subject

    Air Transport Association (ATA) of America Code 26, Fire 
protection.

(e) Reason

    This AD was prompted by a report that during a calibration 
check, some torqueing tools used on the final assembly line have 
been found out of tolerance. We are issuing this AD to address sense 
connections and fire extinguishing lines within the pylon area that 
have been under-torqued, which could lead to leaks or disconnections 
of those lines and possibly result in reduced engine control and 
reduced safety margin in case of engine fire.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2019-0081.

(h) Exceptions to EASA AD 2019-0081

    (1) For purposes of determining compliance with the requirements 
of this AD: Where EASA AD 2019-0081 refers to its

[[Page 19881]]

effective date, this AD requires using the effective date of this 
AD.
    (2) The ``Remarks'' section of EASA AD 2019-0081 does not apply 
to 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, 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: [email protected]. 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 Design Organization Approval (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 2019-0081 that contains RC procedures and 
tests: Except as required by paragraphs (h)(1) and (h)(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.
