SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2018–0008, dated January 10, 2018 (referred to after this as the E:\FR\FM\05JNR1.SGM 05JNR1 Federal Register / Vol. 83, No. 108 / Tuesday, June 5, 2018 / Rules and Regulations 25899 Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A350–941 airplanes. The MCAI states: by searching for and locating Docket No. FAA–2018–0490. and opportunity for public comment before issuing this AD are unnecessary. Related Service Information Under 1 CFR Part 51 Comments Invited Following an Airbus quality control review on the final assembly line, it was identified that short retaining pins may have inadvertently been installed at the incorrect location of the main landing gear support structure (MLGSS) forward pintle. On the A350, two short retaining pins are installed through the fuse pin carrier and four long retaining pins are installed through the trunnion block. These six retaining pins are to prevent rotation and migration of the fuse pins. This condition, if not detected and corrected, could lead to premature failure of the retaining pin, subsequent fuse pin migration and disconnection, with consequent main landing gear collapse, possibly resulting in damage to the aeroplane and injury to the occupants. To address this potential unsafe condition, Airbus issued Service Bulletin (SB) A350– 57–P011 to provide inspection instructions. For the reasons described above, this [EASA] AD requires a one-time detailed inspection (DET) of the four retaining pins installed in the MLGSS trunnion block, both left hand (LH) and right hand (RH) sides [for nonconforming (incorrect) pins, i.e., those having a gap between the retaining pin and the forward surface of the trunnion block], and, depending on findings, accomplishment of applicable [related investigative actions, i.e., a detailed inspection for damage or deformation of nonconforming pins and] corrective action(s) [including repairing or replacing damaged (cracked), deformed, or nonconforming retaining pins]. Airbus has issued Service Bulletin A350–57–P011, dated May 17, 2017. This service information describes procedures for a detailed inspection of the four retaining pins installed in the MLGSS trunnion block, left- and righthand sides, and related investigative and corrective actions. This service information 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 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 and service information referenced above. We are issuing this AD because we 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. FAA’s Determination of the Effective Date Since none of the affected aircraft are currently on the U.S. Register, notice You may examine the MCAI on the internet at http://www.regulations.gov This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite 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–2018–0490; Product Identifier 2018–NM–018–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance Currently, there are no affected U.S.registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, we provide the following cost estimates to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product 6 work-hours × $85 per hour = $510 ...................................................................................................................... $0 $510 We estimate the following costs to do any necessary on-condition replacements that would be required based on the results of any required actions. We have no way of determining the number of aircraft that might need these on-condition replacements: ESTIMATED COSTS OF ON-CONDITION ACTIONS Cost per product Parts cost Up to 16 work-hours × $85 per hour = Up to $1,360 ............ amozie on DSK3GDR082PROD with RULES Labor cost Up to $16,000 ........................................................................ We have received no definitive data that would enable us to provide cost estimates for the on-condition repairs specified in this AD. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected VerDate Sep<11>2014 16:50 Jun 04, 2018 Jkt 244001 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 PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 Up to $17,360 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, E:\FR\FM\05JNR1.SGM 05JNR1 25900 Federal Register / Vol. 83, No. 108 / Tuesday, June 5, 2018 / Rules and Regulations 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 to the Director of the System Oversight Division. Regulatory Findings We 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; 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.

SUPPLEMENTARY INFORMATION: Jkt 244001 The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it amends Class E airspace extending upward from 700 feet above the surface at Halliburton Field, Duncan, OK, to support instrument flight rules operations at this airport. History The FAA published a notice of proposed rulemaking in the Federal Register (83 FR 10644; March 12, 2018) for Docket No. FAA–2018–0100 to amend the Class E airspace extending upward from 700 feet above the surface at Halliburton Field, Duncan, OK. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 25901 proposal to the FAA. No comments were received. Class E airspace designations are published in paragraphs 6005 of FAA Order 7400.11B, dated August 3, 2017, and effective September 15, 2017, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order. Availability and Summary of Documents for Incorporation by Reference This document amends FAA Order 7400.11B, Airspace Designations and Reporting Points, dated August 3, 2017, and effective September 15, 2017. FAA Order 7400.11B is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.11B lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. The Rule This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 modifies the Class E airspace extending upward from 700 feet above the surface to within a 6.6-mile radius (decreased from a 6.7-mile radius) at Halliburton Field, Duncan, OK, and removes the extension to the north of the airport associated with the Halliburton Field Localizer. This action also adds an extension within 4 miles each side of the 359° bearing from the airport from the 6.6-mile radius to 11.6 miles north of the airport. The geographic coordinates of the airport are also being updated to coincide with the FAA’s aeronautical database, and the name of the city associated with the airport in the airspace legal description is being removed to comply with a change to FAA Order 7400.2L, Procedures for Handling Airspace Matters. This action is necessary due to an airspace review caused by the decommissioning of the Duncan VOR as part of the VOR MON Program and cancellation of the associated instrument procedures. Regulatory Notices and Analyses The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current, is non-controversial and unlikely to result in adverse or negative comments. It, therefore: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 E:\FR\FM\05JNR1.SGM 05JNR1

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2018-0008, dated January 10, 2018 (referred to 
after this as the

[[Page 25899]]

Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Airbus Model A350-941 
airplanes. The MCAI states:

    Following an Airbus quality control review on the final assembly 
line, it was identified that short retaining pins may have 
inadvertently been installed at the incorrect location of the main 
landing gear support structure (MLGSS) forward pintle. On the A350, 
two short retaining pins are installed through the fuse pin carrier 
and four long retaining pins are installed through the trunnion 
block. These six retaining pins are to prevent rotation and 
migration of the fuse pins.
    This condition, if not detected and corrected, could lead to 
premature failure of the retaining pin, subsequent fuse pin 
migration and disconnection, with consequent main landing gear 
collapse, possibly resulting in damage to the aeroplane and injury 
to the occupants.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A350-57-P011 to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time detailed inspection (DET) of the four retaining pins installed 
in the MLGSS trunnion block, both left hand (LH) and right hand (RH) 
sides [for nonconforming (incorrect) pins, i.e., those having a gap 
between the retaining pin and the forward surface of the trunnion 
block], and, depending on findings, accomplishment of applicable 
[related investigative actions, i.e., a detailed inspection for 
damage or deformation of nonconforming pins and] corrective 
action(s) [including repairing or replacing damaged (cracked), 
deformed, or nonconforming retaining pins].

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0490.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A350-57-P011, dated May 17, 
2017. This service information describes procedures for a detailed 
inspection of the four retaining pins installed in the MLGSS trunnion 
block, left- and right-hand sides, and related investigative and 
corrective actions. This service information 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 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 and service 
information referenced above. We are issuing this AD because we 
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.

FAA's Determination of the Effective Date

    Since none of the affected aircraft are currently on the U.S. 
Register, notice and opportunity for public comment before issuing this 
AD are unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite 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-2018-0490; Product 
Identifier 2018-NM-018-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, we provide the following cost estimates to comply with this AD:

                  Estimated Costs for Required Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
6 work-hours x $85 per hour = $510....              $0             $510
------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
replacements that would be required based on the results of any 
required actions. We have no way of determining the number of aircraft 
that might need these on-condition replacements:


                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
          Labor cost              Parts cost        Cost per product
------------------------------------------------------------------------
Up to 16 work-hours x $85 per  Up to $16,000..  Up to $17,360
 hour = Up to $1,360.
------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition repairs specified in this AD.
    According to the manufacturer, some or all of the costs of this 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,

[[Page 25900]]

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 to 
the Director of the System Oversight Division.

Regulatory Findings

    We 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;
    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.

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

(g) Detailed Inspection

    Before exceeding 1,880 flight cycles since first flight of the 
airplane, accomplish a detailed inspection for nonconformance 
(incorrect retaining pins, i.e., those having a gap between the 
retaining pin and the forward surface of the trunnion block) of the 
four retaining pins installed in the MLGSS trunnion block, left- and 
right-hand sides and related investigative actions, in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A350-57-P011, dated May 17, 2017.

(h) Corrective Actions

    (1) If, during any inspection required by paragraph (g) of this 
AD, any nonconforming retaining pin is found and that pin has damage 
(including cracks) or deformation: Before further flight, repair 
using a method approved by the Manager, International Section, 
Transport Standards Branch, FAA; or the European Aviation Safety 
Agency (EASA); or Airbus's EASA Design Organization Approval (DOA). 
If approved by the DOA, the approval must include the DOA-authorized 
signature.
    (2) If, during any inspection required by paragraph (g) of this 
AD, any nonconforming but undamaged and undeformed retaining pin is 
found: Before exceeding 1,880 flight cycles since first flight of 
the airplane, replace the nonconforming pin(s) with new conforming 
pins in accordance with the Accomplishment Instructions of Airbus 
Service Bulletin A350-57-P011, dated May 17, 2017.

(i) Other FAA AD Provisions

If approved by the DOA, the approval must include the DOA-authorized 
signature.
    (3) Required for Compliance (RC): If any service information 
contains procedures or tests that are identified as RC, those 
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.
