Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0020, dated January 31, 2019 (‘‘EASA AD 2019–0020’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A350–941 and –1041 airplanes. The MCAI states: Cracks have been found within the ring gears of an SGRA. Investigation identified that this is due to a change in the manufacturing process of the 300M steel raw material, that did not have adequate postproduction non destructive testing for potential cracks. A batch of SGRA has been identified as having been subject to this manufacturing process. This condition, if not detected and corrected, could, in combination with an independent failure on the second SGRA of the same slat surface, lead to detachment of the slat surface, possibly resulting in reduced control of the aeroplane and/or injury to persons on the ground. To address this potential unsafe condition, Airbus issued the SB [Service Bulletin A350– 27–P026] to provide instructions to replace the affected parts, referencing the applicable Liebherr SB for in-shop correction. For the reason described above, this [EASA] AD requires replacement of each affected part with a serviceable part. Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0020 describes procedures for replacing the affected SGRAs. 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 14039 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 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 2019–0020 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 2019–0020 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with the provisions specified in EASA AD 2019–0020, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in EASA AD 2019–0020 that is required for compliance with EASA AD 2019–0020 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2019– 0194 after the FAA final rule is published. Costs of Compliance We estimate that this proposed AD affects 12 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 25 work-hours × $85 per hour = $2,125 ..................................................................................... $0 $2,125 $25,500 * We have received no definitive data that would enable us to provide cost estimates for the parts specified in this proposed AD. VerDate Sep<11>2014 17:21 Apr 08, 2019 Jkt 247001 PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 E:\FR\FM\09APP1.SGM 09APP1 14040 Federal Register / Vol. 84, No. 68 / Tuesday, April 9, 2019 / Proposed Rules 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. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our 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. 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. amozie on DSK9F9SC42PROD with PROPOSALS 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 VerDate Sep<11>2014 17:21 Apr 08, 2019 Jkt 247001 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.

Discussion The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2018–0223, dated October 17, 2018 (referred to after this as ‘‘the MCAI’’), to address the unsafe condition on these products. The MCAI states: PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 14041 During dynamic tests of the seat energy absorber, a too long stroke was identified. Analysis indicated that, when the seat is used in low height adjustment during an emergency landing, the energy absorber may not function as intended. This condition, if not corrected, could lead to impact on lower stop of the energy absorber stroke, possible resulting in injury to the seat occupant. To address this unsafe condition, B/E Aerospace Fischer issued the SB, providing instructions to replace the seat energy absorber assembly and to re-identify the seat. For the reason described above, this [EASA] AD requires modification of the affected seats and reidentification.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0020, dated January 31, 2019 
(``EASA AD 2019-0020'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A350-941 and -1041 airplanes. The 
MCAI states:

    Cracks have been found within the ring gears of an SGRA. 
Investigation identified that this is due to a change in the 
manufacturing process of the 300M steel raw material, that did not 
have adequate post-production non destructive testing for potential 
cracks. A batch of SGRA has been identified as having been subject 
to this manufacturing process.
    This condition, if not detected and corrected, could, in 
combination with an independent failure on the second SGRA of the 
same slat surface, lead to detachment of the slat surface, possibly 
resulting in reduced control of the aeroplane and/or injury to 
persons on the ground.
    To address this potential unsafe condition, Airbus issued the SB 
[Service Bulletin A350-27-P026] to provide instructions to replace 
the affected parts, referencing the applicable Liebherr SB for in-
shop correction.
    For the reason described above, this [EASA] AD requires 
replacement of each affected part with a serviceable part.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0020 describes procedures for replacing the affected 
SGRAs. 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 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 2019-0020 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 2019-0020 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with the 
provisions specified in EASA AD 2019-0020, through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Service information specified in EASA AD 
2019-0020 that is required for compliance with EASA AD 2019-0020 will 
be available on the internet at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2019-0194 after the FAA final rule is 
published.

Costs of Compliance

    We estimate that this proposed AD affects 12 airplanes of U.S. 
registry. We estimate 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

----------------------------------------------------------------------------------------------------------------
* We have received no definitive data that would enable us to provide cost estimates for the parts specified in
  this proposed AD.


[[Page 14040]]

    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. We do not control warranty coverage for 
affected individuals. As a result, we have included all known costs in 
our 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.
    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.

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

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-2019-0194; Product Identifier 2019-NM-
009-AD.

(a) Comments Due Date

    We must receive comments by May 24, 2019.

(b) Affected ADs

    This AD was prompted by reports of cracks within the ring gears 
of a slat geared rotary actuator (SGRA), resulting from a change in 
the raw material manufacturing process. We are issuing this AD to 
address cracking of SGRA ring gears. This condition, if not detected 
and corrected, could, in combination with an independent failure on 
the second SGRA of the same slat surface, lead to detachment of the 
slat surface, possibly resulting in reduced control of the airplane 
and injury to persons on the ground.

(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, European Aviation Safety Agency (EASA) AD 2019-
0020, dated January 31, 2019 (``EASA AD 2019-0020'').

(h) Exceptions to EASA AD 2019-0020

    (1) For purposes of determining compliance with the requirements 
of this AD: Where EASA AD 2019-0020 refers to its effective date, 
this AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2019-0020 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 2019-0020 that contains RC procedures and 
tests: Except as required by paragraph (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.
