Airworthiness Directive (AD) 2014–14–
06 for all Airbus Model A318–111 and
–112 airplanes; Model A319–111, –112,
–113, –114, and –115 airplanes; Model
A320–111, –211, –212, and –214
airplanes; and Model A321–111, –112,
–211, –212, and –213 airplanes. AD
2014–14–06 required inspecting the aft
engine mount retainers for surface
finish, cracks, and failure, and
replacement if necessary. This new AD
requires repetitive inspections for
damaged, cracked, broken, and missing
aft engine mount retainers, and
replacement if necessary. This AD was
prompted by inspection results that
have shown that the main cause of crack
initiation in the aft engine mount
retainers is the vibration dynamic effect
that affects both retainers, either with
‘‘dull’’ or ‘‘bright’’ surface finishes. We
are issuing this AD to detect and correct
failure of retainer brackets of the aft
engine mount and consequent 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.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014–14–06,
Amendment 39–17901 (79 FR 42655,
July 23, 2014) (‘‘AD 2014–14–06’’). AD
2014–14–06 applied to all Model A318–
111 and –112 airplanes; Model A319–
111, –112, –113, –114, and –115
airplanes; Model A320–111, –211, –212,
and –214 airplanes; and Model A321–
111, –112, –211, –212, and –213
airplanes. The NPRM published in the
Federal Register on September 17, 2015
(80 FR 55798) (‘‘the NPRM’’). The
NPRM was prompted by inspection
results that have shown that the main
cause of crack initiation in the aft
engine mount retainers is the vibration
dynamic effect that affects both
retainers, either with ‘‘dull’’ or ‘‘bright’’
surface finishes. The NPRM proposed to
continue to require inspecting the aft
engine mount retainers for surface
finish, cracks, and failure, and
replacement if necessary. The NPRM
also proposed to require repetitive
inspections for damaged, cracked
broken, and missing aft engine mount
retainers, and replacement if necessary.
We are issuing this AD to detect and
correct failure of retainer brackets of the
aft engine mount and consequent 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.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2015–0021, dated February 13,
2015 (referred to after this as the
Mandatory Continuing Airworthiness
Information, or ‘‘the MCAI’’), to correct
an unsafe condition. The MCAI states:
During in-service inspections, several aft
engine mount 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 injury to person on the
ground.
To address this potential unsafe condition,
EASA issued AD 2013–0050 (https://
ad.easa.europa.eu/blob/easa_ad_2013_0050_
superseded.pdf/AD_2013-0050_1 [which
corresponds to FAA AD 2014–14–06] to
require detailed inspections (DET) of the aft
engine mount retainers and the replacement
of all retainers with dull finish with retainers
having a bright finish.
Since that [EASA] AD was issued,
inspection results have shown 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.
For the reasons described above, this
[EASA] AD retains the requirements of EASA
AD 2013–0050, which is superseded, and
requires repetitive DET of all aft engine
mount retainers and, depending on findings
[damaged, cracked, broken, or missing
retainers], their replacement.
This [EASA] AD is considered to be an
interim action, pending development and
availability of a final solution.
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–2015–
3632.
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.
E:\FR\FM\12JYR1.SGM
12JYR1
Federal Register / Vol. 81, No. 133 / Tuesday, July 12, 2016 / Rules and Regulations
Request To Use Alternative Inspection
Method
Delta Airlines (DAL) requested that
we revise paragraph (m) of the NPRM to
approve use of a boroscope with 10X
magnification when performing the
inspection of the center aft engine
mount inner retainer as an option to
removing the center retainer. DAL stated
that this procedure was allowed by the
FAA in Alternative Method of
Compliance (AMOC) ANM–116–14–
423, dated September 16, 2014, for AD
2014–14–06. DAL stated that this
procedure provides an equivalent level
of safety since the detectability of the
subject condition using this alternate
inspection method is the same as a
detailed visual inspection using 10X
magnification, mirror, and light.
We disagree with DAL’s request.
AMOC ANM–116–14–423, dated
September 16, 2014, provides an AMOC
for replacing 10X magnification, mirror,
and light with a boroscope with 10X
magnification but that AMOC is not an
option to removing the center retainer.
However, under the provisions of
paragraph (q)(1) of this AD, we will
consider requests for approval of
alternative procedures, if sufficient data
are submitted to substantiate that the
change would provide an acceptable
level of safety. We have not changed
this AD in this regard.
We have clarified in paragraph
(q)(1)(ii) of this AD that AMOCs
approved previously for AD 2014–14–
06, are approved as AMOCs for the
corresponding provisions of paragraphs
(g) and (i) of this AD.
mstockstill on DSK3G9T082PROD with RULES
Request To Use Later Revisions of
Service Information
DAL requested that we permit use of
later approved revisions of the service
information. DAL stated that Airbus has
released Airbus Service Bulletin A320–
71–1060, Revision 01, dated April 7,
2015.
We partially agree with DAL’s
request. We do not agree to include an
allowance for later approved revisions
of the referenced service information.
When referring to a specific service
document in an AD, using the phrase,
‘‘or later FAA-approved revisions,’’
violates the Office of the Federal
Register’s regulations for approving
materials that are incorporated by
reference. See 1 CFR 51.1(f).
However, affected operators may
request approval to use a later revision
of the referenced service document as
an alternative method of compliance,
under the provisions of paragraph (q)(1)
of this AD. We have not changed this
AD in this regard.
VerDate Sep<11>2014
17:56 Jul 11, 2016
Jkt 238001
We agree to reference to Airbus
Service Bulletin A320–71–1060,
Revision 01, dated April 7, 2015, in this
final rule as the appropriate source of
service information for accomplishing
the actions required by paragraphs (l)
and (m) of this AD (referred to as
paragraphs (m) and (n) in the proposed
AD).
We have also redesignated paragraph
(l) of the proposed AD to paragraph
(p)(1) of this AD (the paragraph retains
existing credit information) and added
new paragraphs (p)(2) and (p)(3) of this
AD to provide provisional credit for
Airbus Service Bulletin A320–71–1060,
dated October 9, 2014. For operators to
obtain credit for Airbus Service Bulletin
A320–71–1060, dated October 9, 2014,
for the replacement, operators must use
the torque value units applicable to nut
item (14) specified in Airbus Service
Bulletin A320–71–1060, Revision 01,
dated April 7, 2015. Those torque value
units were incorrectly stated in Airbus
Service Bulletin A320–71–1060, dated
October 9, 2014.
Conclusion
We reviewed the available data,
including 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 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.
Related Service Information Under 1
CFR Part 51
Airbus has issued Service Bulletin
A320–71–1060, Revision 01, dated April
7, 2015. This service information
describes procedures for inspecting the
aft engine mount retainers for surface
finish (dull or bright), for damaged,
cracked, broken, or missing retainers,
and replacement.
Goodrich Aerostructures has issued
Service Bulletin RA32071–160, dated
September 18, 2014. This service
information describes procedures for
inspecting the aft engine mount inner
retainers for cracks or failure, and
replacement.
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 922
airplanes of U.S. registry.

Frm 00011
Fmt 4700
Sfmt 4700
44991
The actions required by AD 2014–14–
06, and retained in this AD, take about
3 work-hours per product, at an average
labor rate of $85 per work-hour. Based
on these figures, the estimated cost of
the actions that are were required by AD
2014–14–06 is $255 per inspection cycle
per product (for two engines).
We also estimate that it would take
about 10 work-hours per product to
comply with the basic requirements of
this AD, and 1 work-hour per product
to report inspection findings. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the
cost of this AD on U.S. operators to be
$862,070, or $935 per product.
In addition, we estimate that any
necessary follow-on actions would take
about 2 work-hours and require parts
costing $10,000, for a cost of $10,170
per product. We have no way of
determining the number of airplanes
that might need these actions.
Paperwork Reduction Act
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to penalty for failure to comply with a
collection of information subject to the
requirements of the Paperwork
Reduction Act unless that collection of
information displays a current valid
OMB control number. The control
number for the collection of information
required by this AD is 2120–0056. The
paperwork cost associated with this AD
has been detailed in the Costs of
Compliance section of this document
and includes time for reviewing
instructions, as well as completing and
reviewing the collection of information.
Therefore, all reporting associated with
this AD is mandatory. Comments
concerning the accuracy of this burden
and suggestions for reducing the burden
should be directed to the FAA at 800

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

12JYR1
44992
Federal Register / Vol. 81, No. 133 / Tuesday, July 12, 2016 / Rules and Regulations
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.

paragraph (g) of this AD.
(2) Within 50 flight cycles after doing the
first detailed inspection specified in
paragraph (g) of this AD: Replace all dull
finish retainers with new retainers, in
accordance with Section 4.2.3.1,
‘‘Replacement Procedure,’’ of Airbus AOT
A71N001–12, Rev. 2, dated February 27,
2013.
(d) Subject
Air Transport Association (ATA) of
America Code 71, Powerplant.
This paragraph restates the requirements of
paragraph (j) of AD 2014–14–06, with no
changes. If, during any detailed inspection
specified in paragraph (g) of this AD, any
installed aft engine mount retainer is found
cracked or failed: Before further flight,
replace all affected aft engine mount retainers
with new retainers, in accordance with
Section 4.2.3, ‘‘Replacement Procedure,’’ of
Airbus AOT A71N001–12, Rev. 2, dated
February 27, 2013.
(e) Reason
This AD was prompted by inspection
results that have shown that the main cause
of crack initiation in the aft engine mount
retainers is the vibration dynamic effect that
affects both retainers, either with ‘‘dull’’ or
‘‘bright’’ surface finishes. We are issuing this
AD to detect and correct failure of retainer
brackets of the aft engine mount and
consequent 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.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
(g) Retained Inspection, With No Changes
This paragraph restates the requirements of
paragraph (g) of AD 2014–14–06, with no
changes. Within 3 months after August 27,
2014 (the effective date of AD 2014–14–06):
Do a detailed inspection of the aft engine
mount retainers for surface finish (dull or
bright), and for cracks and failure, in
accordance with Section 4.2.2, ‘‘Inspection
Requirements,’’ of Airbus Alert Operators
Transmission (AOT) A71N001–12, Rev. 2,
dated February 27, 2013, except as specified
in paragraph (h) of this AD.
(h) Retained Exception to Paragraph (g) of
This AD, With No Changes
This paragraph restates the requirements of
paragraph (h) of AD 2014–14–06, with no
changes. The actions required by paragraph

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-14-06 for
all Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, -
113, -114, and -115 airplanes; Model A320-111, -211, -212, and -214
airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. AD
2014-14-06 required inspecting the aft engine mount retainers for
surface finish, cracks, and failure, and replacement if necessary. This
new AD requires repetitive inspections for damaged, cracked, broken,
and missing aft engine mount retainers, and replacement if necessary.
This AD was prompted by inspection results that have shown that the
main cause of crack initiation in the aft engine mount retainers is the
vibration dynamic effect that affects both retainers, either with
``dull'' or ``bright'' surface finishes. We are issuing this AD to
detect and correct failure of retainer brackets of the aft engine mount
and consequent 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.
DATES: This AD is effective August 16, 2016.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 16,
2016.
The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014-14-06, Amendment 39-17901 (79 FR 42655,
July 23, 2014) (``AD 2014-14-06''). AD 2014-14-06 applied to all Model
A318-111 and -112 airplanes; Model A319-111, -112, -113, -114, and -115
airplanes; Model A320-111, -211, -212, and -214 airplanes; and Model
A321-111, -112, -211, -212, and -213 airplanes. The NPRM published in
the Federal Register on September 17, 2015 (80 FR 55798) (``the
NPRM''). The NPRM was prompted by inspection results that have shown
that the main cause of crack initiation in the aft engine mount
retainers is the vibration dynamic effect that affects both retainers,
either with ``dull'' or ``bright'' surface finishes. The NPRM proposed
to continue to require inspecting the aft engine mount retainers for
surface finish, cracks, and failure, and replacement if necessary. The
NPRM also proposed to require repetitive inspections for damaged,
cracked broken, and missing aft engine mount retainers, and replacement
if necessary. We are issuing this AD to detect and correct failure of
retainer brackets of the aft engine mount and consequent 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.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2015-0021, dated February 13, 2015 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition. The MCAI states:
During in-service inspections, several aft engine mount
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 injury to person on the ground.
To address this potential unsafe condition, EASA issued AD 2013-
0050 (https://ad.easa.europa.eu/blob/easa_ad_2013_0050_superseded.pdf/AD_2013-0050_1 [which corresponds
to FAA AD 2014-14-06] to require detailed inspections (DET) of the
aft engine mount retainers and the replacement of all retainers with
dull finish with retainers having a bright finish.
Since that [EASA] AD was issued, inspection results have shown
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.
For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2013-0050, which is superseded, and requires
repetitive DET of all aft engine mount retainers and, depending on
findings [damaged, cracked, broken, or missing retainers], their
replacement.
This [EASA] AD is considered to be an interim action, pending
development and availability of a final solution.
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-2015-
3632.
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.
[[Page 44991]]
Request To Use Alternative Inspection Method
Delta Airlines (DAL) requested that we revise paragraph (m) of the
NPRM to approve use of a boroscope with 10X magnification when
performing the inspection of the center aft engine mount inner retainer
as an option to removing the center retainer. DAL stated that this
procedure was allowed by the FAA in Alternative Method of Compliance
(AMOC) ANM-116-14-423, dated September 16, 2014, for AD 2014-14-06. DAL
stated that this procedure provides an equivalent level of safety since
the detectability of the subject condition using this alternate
inspection method is the same as a detailed visual inspection using 10X
magnification, mirror, and light.
We disagree with DAL's request. AMOC ANM-116-14-423, dated
September 16, 2014, provides an AMOC for replacing 10X magnification,
mirror, and light with a boroscope with 10X magnification but that AMOC
is not an option to removing the center retainer. However, under the
provisions of paragraph (q)(1) of this AD, we will consider requests
for approval of alternative procedures, if sufficient data are
submitted to substantiate that the change would provide an acceptable
level of safety. We have not changed this AD in this regard.
We have clarified in paragraph (q)(1)(ii) of this AD that AMOCs
approved previously for AD 2014-14-06, are approved as AMOCs for the
corresponding provisions of paragraphs (g) and (i) of this AD.
Request To Use Later Revisions of Service Information
DAL requested that we permit use of later approved revisions of the
service information. DAL stated that Airbus has released Airbus Service
Bulletin A320-71-1060, Revision 01, dated April 7, 2015.
We partially agree with DAL's request. We do not agree to include
an allowance for later approved revisions of the referenced service
information. When referring to a specific service document in an AD,
using the phrase, ``or later FAA-approved revisions,'' violates the
Office of the Federal Register's regulations for approving materials
that are incorporated by reference. See 1 CFR 51.1(f).
However, affected operators may request approval to use a later
revision of the referenced service document as an alternative method of
compliance, under the provisions of paragraph (q)(1) of this AD. We
have not changed this AD in this regard.
We agree to reference to Airbus Service Bulletin A320-71-1060,
Revision 01, dated April 7, 2015, in this final rule as the appropriate
source of service information for accomplishing the actions required by
paragraphs (l) and (m) of this AD (referred to as paragraphs (m) and
(n) in the proposed AD).
We have also redesignated paragraph (l) of the proposed AD to
paragraph (p)(1) of this AD (the paragraph retains existing credit
information) and added new paragraphs (p)(2) and (p)(3) of this AD to
provide provisional credit for Airbus Service Bulletin A320-71-1060,
dated October 9, 2014. For operators to obtain credit for Airbus
Service Bulletin A320-71-1060, dated October 9, 2014, for the
replacement, operators must use the torque value units applicable to
nut item (14) specified in Airbus Service Bulletin A320-71-1060,
Revision 01, dated April 7, 2015. Those torque value units were
incorrectly stated in Airbus Service Bulletin A320-71-1060, dated
October 9, 2014.
Conclusion
We reviewed the available data, including 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 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.

take about 3 work-hours per product, at an average labor rate of $85
per work-hour. Based on these figures, the estimated cost of the
actions that are were required by AD 2014-14-06 is $255 per inspection
cycle per product (for two engines).
We also estimate that it would take about 10 work-hours per product
to comply with the basic requirements of this AD, and 1 work-hour per
product to report inspection findings. The average labor rate is $85
per work-hour. Based on these figures, we estimate the cost of this AD
on U.S. operators to be $862,070, or $935 per product.
In addition, we estimate that any necessary follow-on actions would
take about 2 work-hours and require parts costing $10,000, for a cost
of $10,170 per product. We have no way of determining the number of
airplanes that might need these actions.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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
[[Page 44992]]
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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 removing Airworthiness Directive (AD)
2014-14-06, Amendment 39-17901 (79 FR 42655, July 23, 2014), and adding
the following new AD:
2016-14-09 Airbus: Amendment 39-18590. Docket No. FAA-2015-3632;
Directorate Identifier 2015-NM-023-AD.
(a) Effective Date
This AD is effective August 16, 2016.
(b) Affected ADs
This AD replaces AD 2014-14-06, Amendment 39-17901 (79 FR 42655,
July 23, 2014) (``AD 2014-14-06'').
(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 inspection results that have shown that
the main cause of crack initiation in the aft engine mount retainers
is the vibration dynamic effect that affects both retainers, either
with ``dull'' or ``bright'' surface finishes. We are issuing this AD
to detect and correct failure of retainer brackets of the aft engine
mount and consequent 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Inspection, With No Changes
This paragraph restates the requirements of paragraph (g) of AD
2014-14-06, with no changes. Within 3 months after August 27, 2014
(the effective date of AD 2014-14-06): Do a detailed inspection of
the aft engine mount retainers for surface finish (dull or bright),
and for cracks and failure, in accordance with Section 4.2.2,
``Inspection Requirements,'' of Airbus Alert Operators Transmission

maintenance records verifies that no aft engine mount retainers have
been replaced since first flight of the airplane.
(i) Retained Repetitive Inspection and Retainer Replacement for Dull
Finish Retainers, With No Changes
This paragraph restates the requirements of paragraph (i) of AD
2014-14-06, with no changes. If, during the detailed inspection
required by paragraph (g) of this AD, any installed dull finish aft
engine mount retainer is found without cracks and not failed: Do the
actions specified in paragraphs (i)(1) and (i)(2) of this AD.
(1) Within 25 flight cycles after doing the actions required by
paragraph (g) of this AD: Repeat the detailed inspection specified
in paragraph (g) of this AD.
(2) Within 50 flight cycles after doing the first detailed
inspection specified in paragraph (g) of this AD: Replace all dull

Bulletin A320-71-1060, Revision 01, dated April 7, 2015.
[[Page 44993]]
(n) New Requirement of This AD: No Terminating Action
Replacement of retainers on an airplane, as required by
paragraph (m) of this AD, does not constitute terminating action for
the repetitive inspections required by paragraph (l) of this AD for
that airplane.
(o) New Requirement of This AD: Required Reporting
Submit a report of positive findings of any inspection required
by paragraph (l) of this AD to Airbus at the applicable time
