The Code of Federal Regulations is sold by the Superintendent of Documents. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2017–0809; Product Identifier 2017–NM–094–AD; Amendment 39–19030; AD 2017–18–21] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. AGENCY: We are superseding Airworthiness Directive (AD) 2017–13– 12, which applied to all Airbus Model A318 and A319 series airplanes; Model A320–211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. AD 2017–13–12 required modification or replacement of certain side stay assemblies of the main landing gear (MLG). This new AD clarifies the formatting of a figure in the published version of AD 2017–13–12. This new AD was prompted by reports indicating that affected parties misinterpreted the applicability of the affected part numbers due to the formatting of a figure in the published version of AD 2017–13–12, which could result in a negative effect on compliance. We are issuing this AD to address the unsafe condition on these products. SUMMARY: This AD is effective September 28, 2017.

SUPPLEMENTARY INFORMATION: Discussion On June 19, 2017, we issued AD 2017–13–12, Amendment 39–18942 (82 FR 30949, July 5, 2017) (‘‘AD 2017–13– 12’’), which applied to all Airbus Model A318 series airplanes and A319 series airplanes; Model A320–211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. AD 2017–13–12 was prompted by an evaluation by the design approval holder (DAH), which indicates that the main landing gear (MLG) does not comply with certification specifications, which could result in a locking failure of the MLG side stay. AD 2017–13–12 required modification or replacement of certain MLG side stay assemblies. We issued AD 2017–13–12 prevent possible collapse of the MLG during takeoff and landing. Since we issued AD 2017–13–12, we have received reports indicating that affected parties misinterpreted the applicability of the affected part numbers due to the formatting of figure 1 to paragraphs (g), (h), and (i) in the published version of AD 2017–13–12, which could result in a negative effect on compliance. Therefore, we have determined that clarification of the formatting of the published figure is necessary. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016– 0018R1, dated September 14, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318 and A319 series airplanes; Model A320– 211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, and –232 airplanes. The EASA AD is referenced in AD 2017–13–12. EASA has not E:\FR\FM\13SER1.SGM 13SER1 42930 Federal Register / Vol. 82, No. 176 / Wednesday, September 13, 2017 / Rules and Regulations revised its AD since the issuance of AD 2017–13–12. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0809. Related Service Information Under 1 CFR Part 51 We have reviewed the following service information. • Airbus Service Bulletin A320–32– 1429, Revision 01, dated February 29, 2016. • Messier-Bugatti-Dowty Service Bulletin 200–32–315, dated April 24, 2015. • Messier-Bugatti-Dowty Service Bulletin 201–32–63, dated April 24, 2015. The service information describes procedures for modifying the MLG side stay assembly. The Messier-BugattiDowty documents are distinct since they apply to different airplane models. 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 Justification and Determination of the Effective Date We are superseding AD 2017–13–12 to clarify the formatting of a figure in the regulatory text of the published AD. No other changes have been made to AD 2017–13–12. Therefore, we determined that notice and opportunity for prior public comment 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–2017–0809; Product Identifier 2017–NM–094–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 because of 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 We estimate that this AD affects 959 airplanes of U.S. registry. This AD adds no new economic burden to AD 2017– 13–12. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Replacement or modification (retained actions from AD 2017–13–12). sradovich on DSK3GMQ082PROD with RULES Action 9 work-hours × $85 per hour = $765 ............. 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 AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. VerDate Sep<11>2014 15:59 Sep 12, 2017 Jkt 241001 Parts cost 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); PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 Cost per product $14,104 Cost on U.S. operators $14,869 $14,259,371 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.

14 CFR Part 39

[Docket No. FAA-2017-0809; Product Identifier 2017-NM-094-AD; Amendment 
39-19030; AD 2017-18-21]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-13-12, 
which applied to all Airbus Model A318 and A319 series airplanes; Model 
A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017-
13-12 required modification or replacement of certain side stay 
assemblies of the main landing gear (MLG). This new AD clarifies the 
formatting of a figure in the published version of AD 2017-13-12. This 
new AD was prompted by reports indicating that affected parties 
misinterpreted the applicability of the affected part numbers due to 
the formatting of a figure in the published version of AD 2017-13-12, 
which could result in a negative effect on compliance. We are issuing 
this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion

    On June 19, 2017, we issued AD 2017-13-12, Amendment 39-18942 (82 
FR 30949, July 5, 2017) (``AD 2017-13-12''), which applied to all 
Airbus Model A318 series airplanes and A319 series airplanes; Model 
A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017-
13-12 was prompted by an evaluation by the design approval holder 
(DAH), which indicates that the main landing gear (MLG) does not comply 
with certification specifications, which could result in a locking 
failure of the MLG side stay. AD 2017-13-12 required modification or 
replacement of certain MLG side stay assemblies. We issued AD 2017-13-
12 prevent possible collapse of the MLG during takeoff and landing.
    Since we issued AD 2017-13-12, we have received reports indicating 
that affected parties misinterpreted the applicability of the affected 
part numbers due to the formatting of figure 1 to paragraphs (g), (h), 
and (i) in the published version of AD 2017-13-12, which could result 
in a negative effect on compliance. Therefore, we have determined that 
clarification of the formatting of the published figure is necessary.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2016-0018R1, dated September 14, 2016 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Model A318 and A319 series 
airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; 
and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes. The EASA AD is referenced in AD 2017-13-12. EASA has not

[[Page 42930]]

revised its AD since the issuance of AD 2017-13-12.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0809.

Related Service Information Under 1 CFR Part 51

    We have reviewed the following service information.
     Airbus Service Bulletin A320-32-1429, Revision 01, dated 
February 29, 2016.
     Messier-Bugatti-Dowty Service Bulletin 200-32-315, dated 
April 24, 2015.
     Messier-Bugatti-Dowty Service Bulletin 201-32-63, dated 
April 24, 2015.
    The service information describes procedures for modifying the MLG 
side stay assembly. The Messier-Bugatti-Dowty documents are distinct 
since they apply to different airplane models. 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 Justification and Determination of the Effective Date

    We are superseding AD 2017-13-12 to clarify the formatting of a 
figure in the regulatory text of the published AD. No other changes 
have been made to AD 2017-13-12. Therefore, we determined that notice 
and opportunity for prior public comment 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-2017-0809; Product 
Identifier 2017-NM-094-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 because of 
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

    We estimate that this AD affects 959 airplanes of U.S. registry. 
This AD adds no new economic burden to AD 2017-13-12. We estimate the 
following costs to comply with this AD:

                                                 Estimated Costs

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

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 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.

(h) Retained Provisions for Unaffected Airplanes, With No Changes

    This paragraph restates the provisions of paragraph (h) of AD 
2017-13-12, with no changes. An airplane on which Airbus 
Modification (Mod) 156646, Airbus Mod 161202, or Airbus Mod 161346 
has been embodied in production is not affected by the requirements 
of paragraph (g) of this AD, provided it is determined that no part 
having a part number identified in figure 1 to paragraphs (g), (h), 
and (i) of this AD has been installed on that airplane since the 
date of issuance of the original certificate of airworthiness or the 
original export certificate of airworthiness. A review of the 
airplane maintenance records is acceptable to make this 
determination, provided that these records are accurate and can be 
relied upon to conclusively make that determination.

(i) Retained Parts Installation Prohibition, With No Changes

    This paragraph restates the requirements of paragraph (i) of AD 
2017-13-12, with no changes. As of August 9, 2017 (the effective 
date of AD 2017-13-12), do not install on any airplane, an MLG side 
stay assembly having a part number, with the strike number not 
cancelled, as identified in figure 1 to paragraphs (g), (h), and (i) 
of this AD, unless

[[Page 42932]]

it has been modified in accordance with the requirements of 
paragraph (g) of this AD.

(j) Retained Credit for Previous Actions, With No Changes

    This paragraph restates the provisions of paragraph (j) of AD 
2017-13-12, with no changes. This paragraph provides credit for 
actions required by paragraph (g) of this AD, if those actions were 
performed before August 9, 2017 (the effective date of AD 2017-13-
12), using Airbus Service Bulletin A320-32-1429, dated September 10, 
2015.

(k) 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 manager of the International Section, send it to the 
attention of the person identified in paragraph (l)(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 corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or EASA; or Airbus's EASA 
DOA. 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.
