Download as PDF sradovich on DSK3GMQ082PROD with RULES Federal Register / Vol. 82, No. 37 / Monday, February 27, 2017 / Rules and Regulations Assessments are applied uniformly on all handlers, and some of the costs may be passed on to producers. However, decreasing the assessment rate reduces the burden on handlers, and may reduce the burden on producers. In addition, the Committee’s meeting was widely publicized throughout the Walla Walla sweet onion industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the December 6, 2016, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. Finally, interested persons are invited to submit comments on this interim rule, including the regulatory and informational impacts of this action on small businesses. In accordance with the Paperwork Reduction Act of 1995, (44 U.S.C. Chapter 35), the order’s information collection requirements have been previously approved by the Office of Management and Budget (OMB) and assigned OMB No. 0581–0178, Vegetable and Specialty Crops. No changes in those requirements as a result of this action are necessary. Should any changes become necessary, they would be submitted to OMB for approval. This action imposes no additional reporting or recordkeeping requirements on either small or large Walla Walla sweet onion handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. AMS is committed to complying with the E-Government Act, to promote the use of the internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: https://www.ams.usda.gov/ rules-regulations/moa/small-businesses. Any questions about the compliance guide should be sent to Richard Lower at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. After consideration of all relevant material presented, including the information and recommendation submitted by the Committee and other available information, it is hereby found that this rule, as hereinafter set forth, VerDate Sep<11>2014 16:46 Feb 24, 2017 Jkt 241001 will tend to effectuate the declared policy of the Act. Pursuant to 5 U.S.C. 553, it is also found and determined upon good cause that it is impracticable, unnecessary, and contrary to the public interest to give preliminary notice prior to putting this rule into effect, and that good cause exists for not postponing the effective date of this rule until 30 days after publication in the Federal Register because: (1) The 2017 fiscal period begins on January 1, 2017, and the marketing order requires that the rate of assessment for each fiscal period apply to all assessable sweet onions handled during such fiscal period; (2) this action decreases the assessment rate for assessable sweet onions beginning with the 2017 fiscal period; (3) handlers are aware of this action, which was unanimously recommended by the Committee at a public meeting and is similar to other assessment rate actions issued in past years; and (4) this interim rule provides a 60-day comment period, and all comments timely received will be considered prior to finalization of this rule. List of Subjects in 7 CFR Part 956 Marketing agreements, Onions, Reporting and recordkeeping requirements. For the reasons set forth in the preamble, 7 CFR part 956 is amended as follows: PART 956—SWEET ONIONS GROWN IN THE WALLA WALLA VALLEY OF SOUTHEAST WASHINGTON AND NORTHEAST OREGON 1. The authority citation for 7 CFR part 956 continues to read as follows: ■ Authority: 7 U.S.C. 601–674. 2. Section 956.202 is revised to read as follows: ■ § 956.202 Assessment rate. On and after January 1, 2017, an assessment rate of $0.10 per 50-pound bag or equivalent is established for Walla Walla sweet onions. Dated: February 21, 2017.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A318–111, and –112 airplanes, Model A319–111, –112, –113, –114, and –115 airplanes, Model A320–211, –212 and –214 airplanes, and Model A321–111, –112, –211, –212, and –213 airplanes. The NPRM published in the Federal Register on May 31, 2016 (81 FR 34287) (‘‘the NPRM’’). The NPRM was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. The NPRM proposed to require an inspection for, and replacement of, all non-conforming aft engine mount retainers. We are issuing this AD to detect and correct non-conforming retainers of the aft engine mount. This condition could result in the loss of the locking feature of the nuts of the inner and outer pins; loss of the pins will result in the aft mount engine link no longer being secured to the aft engine mount, possibly resulting in damage to the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016–0010R1, dated February 16, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus VerDate Sep<11>2014 16:46 Feb 24, 2017 Jkt 241001 Model A318–111, and –112 airplanes; Model A319–111, –112, –113, –114, and –115 airplanes; Model A320–211, –212, and –214 airplanes; and Model A321– 111, –112, –211, –212, and –213 airplanes. The MCAI states: During in-service inspections, several aft engine mount inner retainers, fitted on aeroplanes equipped with CFM56–5A/5B engines, have been found broken. The results of the initial investigations highlighted that two different types of surface finish had been applied (respectively bright and dull material finishes), and that dull finish affects the strength of the retainer with regard to fatigue properties of the part. The pins which attach the engine link to the aft mount are secured by two nuts, which do not have a self-locking feature; this function is provided by the retainer brackets. In case of failure of the retainer bracket, the locking feature of the nuts of the inner and outer pins is lost; as a result, these nuts could subsequently become loose. In case of full loss of the nuts, there is the potential to also lose the pins, in which case the aft mount link will no longer be secured to the aft engine mount. The same locking feature is used for the three link assemblies of the aft mount. This condition, if not detected and corrected, could lead to in-flight loss of an aft mount link, possibly resulting in damage to the aeroplane and/or injury to persons on the ground. To address this potential unsafe condition, EASA issued AD 2013–0050 [which corresponds to FAA AD 2014–14–06, Amendment 39–17901 (79 FR 42655, July 23, 2014)] to require a detailed inspection (DET) of the aft engine mount inner retainers and the replacement of all retainers with dull finish with retainers having a bright finish. Since that [EASA] AD was issued, inspection results showed that the main cause of crack initiation remains the vibration dynamic effect that affects both retainers, either with ‘‘dull’’ or ‘‘bright’’ surface finishes. The nonconforming ‘‘dull’’ surface’s pitting is an aggravating factor. Consequently, EASA issued AD 2015–0021 [which corresponds to FAA NPRM Docket No. FAA–2015–3632; Directorate Identifier 2015–NM–023–AD (80 FR 55798, September 7, 2015)], retaining the requirements of EASA AD 2013–0050, which was superseded, and requiring repetitive DET of all aft engine mount inner retainers and, depending on findings, their replacement. Since that [EASA] AD was issued, a production quality deficiency was identified by Airbus and UTAS (formerly Goodrich Aerostructures, the engine mount retainer manufacturer) on the delivery of the inner retainer, Part Number (P/N) 238–0252–505, installed in the three Link assemblies of the engine mount fitted on CFM56–5A/5B engines. Airbus issued AOT A71N011–15 and SB A320–71–1070 providing a list of affected parts and applicable corrective actions. Consequently, EASA issued AD 2016– 0010, retaining the requirements of EASA AD 2015–0021, which was superseded, and in addition requiring the identification and replacement of all non-conforming aft engine mount inner retainers. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Since that [EASA] AD was issued, AOT A71N011–15 was revised, removing errors and reducing the list of affected parts. For the reason described above, this [EASA] AD is revised, adding reference to the revised AOT, and removing [EASA] AD appendixes, which content is included in the referenced Airbus documentation. This [EASA] AD is still considered to be an interim action, pending development and availability of a final solution. This AD requires an inspection for, and replacement of, all non-conforming aft engine mount retainers. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 6896. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Remove Part Identification Requirement Delta Airlines (DAL) requested that we remove the requirement to do an inspection to determine the part number of each engine mount inner retainer specified in paragraph (g) of the proposed AD. DAL stated that Airbus Service Bulletin A320–71–1070, dated November 23, 2015, does not specify identifying the part number. DAL stated that identifying the part number has no value in determining the affected population of non-conforming retainers. DAL also requested that we revise the records review language in paragraph (g) of the proposed AD to reference the criteria in paragraphs (g)(1), and (g)(2), and (g)(3) of the proposed AD instead of referring to the part number. We do not agree with DAL’s request to remove the inspection required by paragraph (g) of this AD. However, we do agree that the inspection language should be clarified. Paragraph (g) of this AD, which corresponds with the MCAI, requires doing actions in accordance with Airbus Service Bulletin A320–71– 1070, dated November 23, 2015, which specifies to determine if there is a noncompliant engine mount inner retainer. We have revised paragraph (g) of this AD accordingly. Request To Clarify Engine Mount Retainer DAL requested that we clarify in paragraph (g) of the proposed AD which engine mount retainer (forward or aft) is to be inspected. We agree to clarify. We have revised paragraph (g) of this AD to specify the aft engine mount inner retainer. E:\FR\FM\27FER1.SGM 27FER1 Federal Register / Vol. 82, No. 37 / Monday, February 27, 2017 / Rules and Regulations Requests To Use the Airplane Maintenance Manual (AMM) DAL requested that we include an option for using the AMM to accomplish the required actions. DAL stated that paragraph (g) of the proposed AD specifies that the replacement must be done in accordance with the service information specified in paragraph (h)(1), (h)(2), or (h)(3) of the proposed AD. DAL recommended that operators be allowed to take credit for the replacement through other means such as the AMM. We do not agree with DAL’s request. An AMM is a customized document that varies for each operator and depends on the airplane configuration. In addition, the AMM might not include all required compliance steps to mitigate the risk addressed in this AD. We have not changed this AD in this regard. However, under the provisions of paragraph (l) of this AD, we will consider requests for approval of alternative methods of compliance if sufficient data are submitted to substantiate that the new methods would provide an acceptable level of safety. Requests To Revise Part Installation Prohibition DAL requested that we revise paragraph (j) of the proposed AD to prohibit installation of an engine mount inner retainer in lieu of ‘‘any part.’’ DAL asserted that if not changed, paragraph (j)(l) of the proposed AD will prohibit the installation of all aft mounts identified in table 1 of Airbus Alert Operators Transmission (AOT) A71N011–15, Revision 01, dated February 1, 2016. We agree with DAL’s request. We have revised paragraph (j) of this AD to prohibit installation of certain engine mount inner retainers. DAL requested that we revise paragraph (j)(3) of the proposed AD, which prohibits installation of parts delivered through an unidentified Purchase Order (PO) to provide more specific information for the identification of non-conforming aft engine mount inner retainers. DAL suggested that the proposed AD specify using the original equipment manufacturer (OEM) new part release certificate as a mean of verifying conformity for each aft engine mount inner retainer. DAL explained that it is suggesting this action because nonconforming field parts could be sold on the surplus market prior to the release of the AD under a non-OEM purchase order number. We do not agree with DAL’s request to revise paragraph (j)(3) of the proposed AD. We have determined that paragraph (j)(3) of this AD clearly prohibits installation of parts delivered through an unidentified PO and corresponds with the MCAI. We are unaware of any non-conforming parts delivered through an unidentified PO that have been sold on the surplus market. However, if those parts exist, then they are prohibited from installation as of the effective date of this AD. We have not changed this AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes: 11793 • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. This service information describes procedures for replacement of all non-conforming aft engine mount retainers. • Airbus Service Bulletin A320–71– 1070, dated November 23, 2015. This document also describes procedures for an inspection for non-conforming aft engine mount retainers. • Airbus Alert Operators Transmission (AOT) A71N011–15, Revision 01, dated February 1, 2016. This document also contains the affected purchase order numbers used in identifying the affected parts. • Goodrich Service Bulletin RA32071–165, dated October 9, 2015. This document also contains the affected part numbers. 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. Costs of Compliance We estimate that this AD affects 959 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Inspection ........................ Up to 4 work-hours × $85 per hour = $340 ........... We estimate the following costs to do any necessary replacements that would Parts cost Cost per product $0 be required based on the results of the inspection.

Up to 36 work-hours × $85 per hour = $3,060 ................................... Authority for This Rulemaking section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, VerDate Sep<11>2014 16:46 Feb 24, 2017 Jkt 241001 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 Parts cost $10,000 Cost per product Up to $13,060. detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, E:\FR\FM\27FER1.SGM 27FER1 11794 Federal Register / Vol. 82, No. 37 / Monday, February 27, 2017 / 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. 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: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus Model A318-111, 
and -112 airplanes, Model A319-111, -112, -113, -114, and -115 
airplanes, Model A320-211, -212 and -214 airplanes, and Model A321-111, 
-112, -211, -212, and -213 airplanes. The NPRM published in the Federal 
Register on May 31, 2016 (81 FR 34287) (``the NPRM''). The NPRM was 
prompted by a report of a production quality deficiency on the inner 
retainer installed on link assemblies of the aft engine mount, which 
could result in failure of the retainer. The NPRM proposed to require 
an inspection for, and replacement of, all non-conforming aft engine 
mount retainers. We are issuing this AD to detect and correct non-
conforming retainers of the aft engine mount. This condition could 
result in the loss of the locking feature of the nuts of the inner and 
outer pins; loss of the pins will result in the aft mount engine link 
no longer being secured to the aft engine mount, possibly resulting in 
damage to the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0010R1, dated February 16, 2016 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318-111, and -112 airplanes; Model A319-111, -112, -113, -114, and -
115 airplanes; Model A320-211, -212, and -214 airplanes; and Model 
A321-111, -112, -211, -212, and -213 airplanes. The MCAI states:

    During in-service inspections, several aft engine mount inner 
retainers, fitted on aeroplanes equipped with CFM56-5A/5B engines, 
have been found broken. The results of the initial investigations 
highlighted that two different types of surface finish had been 
applied (respectively bright and dull material finishes), and that 
dull finish affects the strength of the retainer with regard to 
fatigue properties of the part. The pins which attach the engine 
link to the aft mount are secured by two nuts, which do not have a 
self-locking feature; this function is provided by the retainer 
brackets. In case of failure of the retainer bracket, the locking 
feature of the nuts of the inner and outer pins is lost; as a 
result, these nuts could subsequently become loose.
    In case of full loss of the nuts, there is the potential to also 
lose the pins, in which case the aft mount link will no longer be 
secured to the aft engine mount. The same locking feature is used 
for the three link assemblies of the aft mount.
    This condition, if not detected and corrected, could lead to in-
flight loss of an aft mount link, possibly resulting in damage to 
the aeroplane and/or injury to persons on the ground.
    To address this potential unsafe condition, EASA issued AD 2013-
0050 [which corresponds to FAA AD 2014-14-06, Amendment 39-17901 (79 
FR 42655, July 23, 2014)] to require a detailed inspection (DET) of 
the aft engine mount inner retainers and the replacement of all 
retainers with dull finish with retainers having a bright finish. 
Since that [EASA] AD was issued, inspection results showed that the 
main cause of crack initiation remains the vibration dynamic effect 
that affects both retainers, either with ``dull'' or ``bright'' 
surface finishes. The non-conforming ``dull'' surface's pitting is 
an aggravating factor. Consequently, EASA issued AD 2015-0021 [which 
corresponds to FAA NPRM Docket No. FAA-2015-3632; Directorate 
Identifier 2015-NM-023-AD (80 FR 55798, September 7, 2015)], 
retaining the requirements of EASA AD 2013-0050, which was 
superseded, and requiring repetitive DET of all aft engine mount 
inner retainers and, depending on findings, their replacement.
    Since that [EASA] AD was issued, a production quality deficiency 
was identified by Airbus and UTAS (formerly Goodrich Aerostructures, 
the engine mount retainer manufacturer) on the delivery of the inner 
retainer, Part Number (P/N) 238-0252-505, installed in the three 
Link assemblies of the engine mount fitted on CFM56-5A/5B engines. 
Airbus issued AOT A71N011-15 and SB A320-71-1070 providing a list of 
affected parts and applicable corrective actions.
    Consequently, EASA issued AD 2016-0010, retaining the 
requirements of EASA AD 2015-0021, which was superseded, and in 
addition requiring the identification and replacement of all non-
conforming aft engine mount inner retainers.
    Since that [EASA] AD was issued, AOT A71N011-15 was revised, 
removing errors and reducing the list of affected parts.
    For the reason described above, this [EASA] AD is revised, 
adding reference to the revised AOT, and removing [EASA] AD 
appendixes, which content is included in the referenced Airbus 
documentation.
    This [EASA] AD is still considered to be an interim action, 
pending development and availability of a final solution.

    This AD requires an inspection for, and replacement of, all non-
conforming aft engine mount retainers. You may examine the MCAI in the 
AD docket on the Internet at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2016-6896.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Remove Part Identification Requirement

    Delta Airlines (DAL) requested that we remove the requirement to do 
an inspection to determine the part number of each engine mount inner 
retainer specified in paragraph (g) of the proposed AD. DAL stated that 
Airbus Service Bulletin A320-71-1070, dated November 23, 2015, does not 
specify identifying the part number. DAL stated that identifying the 
part number has no value in determining the affected population of non-
conforming retainers. DAL also requested that we revise the records 
review language in paragraph (g) of the proposed AD to reference the 
criteria in paragraphs (g)(1), and (g)(2), and (g)(3) of the proposed 
AD instead of referring to the part number.
    We do not agree with DAL's request to remove the inspection 
required by paragraph (g) of this AD. However, we do agree that the 
inspection language should be clarified. Paragraph (g) of this AD, 
which corresponds with the MCAI, requires doing actions in accordance 
with Airbus Service Bulletin A320-71-1070, dated November 23, 2015, 
which specifies to determine if there is a non-compliant engine mount 
inner retainer. We have revised paragraph (g) of this AD accordingly.

Request To Clarify Engine Mount Retainer

    DAL requested that we clarify in paragraph (g) of the proposed AD 
which engine mount retainer (forward or aft) is to be inspected.
    We agree to clarify. We have revised paragraph (g) of this AD to 
specify the aft engine mount inner retainer.

[[Page 11793]]

Requests To Use the Airplane Maintenance Manual (AMM)

    DAL requested that we include an option for using the AMM to 
accomplish the required actions. DAL stated that paragraph (g) of the 
proposed AD specifies that the replacement must be done in accordance 
with the service information specified in paragraph (h)(1), (h)(2), or 
(h)(3) of the proposed AD. DAL recommended that operators be allowed to 
take credit for the replacement through other means such as the AMM.
    We do not agree with DAL's request. An AMM is a customized document 
that varies for each operator and depends on the airplane 
configuration. In addition, the AMM might not include all required 
compliance steps to mitigate the risk addressed in this AD. We have not 
changed this AD in this regard. However, under the provisions of 
paragraph (l) of this AD, we will consider requests for approval of 
alternative methods of compliance if sufficient data are submitted to 
substantiate that the new methods would provide an acceptable level of 
safety.

Requests To Revise Part Installation Prohibition

    DAL requested that we revise paragraph (j) of the proposed AD to 
prohibit installation of an engine mount inner retainer in lieu of 
``any part.'' DAL asserted that if not changed, paragraph (j)(l) of the 
proposed AD will prohibit the installation of all aft mounts identified 
in table 1 of Airbus Alert Operators Transmission (AOT) A71N011-15, 
Revision 01, dated February 1, 2016.
    We agree with DAL's request. We have revised paragraph (j) of this 
AD to prohibit installation of certain engine mount inner retainers.
    DAL requested that we revise paragraph (j)(3) of the proposed AD, 
which prohibits installation of parts delivered through an unidentified 
Purchase Order (PO) to provide more specific information for the 
identification of non-conforming aft engine mount inner retainers. DAL 
suggested that the proposed AD specify using the original equipment 
manufacturer (OEM) new part release certificate as a mean of verifying 
conformity for each aft engine mount inner retainer. DAL explained that 
it is suggesting this action because non-conforming field parts could 
be sold on the surplus market prior to the release of the AD under a 
non-OEM purchase order number.
    We do not agree with DAL's request to revise paragraph (j)(3) of 
the proposed AD. We have determined that paragraph (j)(3) of this AD 
clearly prohibits installation of parts delivered through an 
unidentified PO and corresponds with the MCAI. We are unaware of any 
non-conforming parts delivered through an unidentified PO that have 
been sold on the surplus market. However, if those parts exist, then 
they are prohibited from installation as of the effective date of this 
AD. We have not changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 959 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
            Action                   Labor cost         Parts cost    Cost per product   Cost on U.S. operators

                                $85 per hour = $340.
----------------------------------------------------------------------------------------------------------------

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

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost            Parts cost           Cost per product

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 11794]]

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.

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.

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):

2017-04-10 Airbus: Amendment 39-18805. Docket No. FAA-2016-6896; 
Directorate Identifier 2016-NM-016-AD.

(a) Effective Date

    This AD is effective April 3, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Airbus airplanes identified in paragraphs 
(c)(1) through (c)(4) of this AD, certificated in any category, all 
manufacturer serial numbers.
    (1) Airbus Model A318-111 and -112 airplanes.
    (2) Airbus Model A319-111, -112, -113, -114, and -115 airplanes.
    (3) Airbus Model A320-211, -212, and -214 airplanes.
    (4) Airbus Model A321-111, -112, -211, -212, and -213 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 71, Powerplant.

(e) Reason

    This AD was prompted by a report of a production quality 
deficiency on the inner retainer installed on link assemblies of the 
aft engine mount, which could result in failure of the retainer. We 
are issuing this AD to detect and correct non-conforming retainers 
of the aft engine mount. This condition could result in loss of the 
locking feature of the nuts of the inner and outer pins; loss of the 
pins will result in the aft mount engine link no longer being 
secured to the aft engine mount, possibly resulting in damage to the 
airplane.

(f) Compliance

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

(g) Inspection and Replacement

    Within 2 months after the effective date of this AD, do an 
inspection to determine if any non-compliant aft engine mount inner 
retainer is installed; and within 2 months after the effective date 
of this AD, replace each part that meets any of the criteria 
specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do the 
inspection in accordance with the service information specified in 
paragraph (h)(1) of this AD. Do the replacement in accordance with 
the service information specified in paragraph (h)(1), (h)(2), or 
(h)(3) of this AD. A review of airplane maintenance records is 
acceptable in lieu of the inspection required by this paragraph, if 
it can be conclusively determined that there are no non-compliant 
aft engine mount inner retainers installed on the airplane.
    (1) An aft engine mount inner retainer from an aft engine mount 
having a serial number listed in table 1 of Airbus Alert Operators 
Transmission (AOT) A71N011-15, Rev 01, dated February 1, 2016.
    (2) An aft engine mount inner retainer installed on an airplane 
between the first flight of the airplane or March 1, 2015 (whichever 
occurs later), and the effective date of this AD, and that can be 
identified by a purchase order (PO) listed in table 2 of Airbus AOT 
A71N011-15, Rev 01, dated February 1, 2016.
    (3) An aft engine mount inner retainer installed on an airplane 
between the first flight of the airplane or March 1, 2015 (whichever 
occurs later), and the effective date of this AD, and that cannot be
