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 August 3, 2016 (81 FR
51142). The NPRM was prompted by
reports of cracks on the 3 o’clock and 9
o’clock pivot fittings of a CFM56
engine’s T/R. The NPRM proposed to
require repetitive inspections for
cracking and corrosion of the 3 o’clock
and 9 o’clock pivot fittings of a CFM56
engine’s T/R, and corrective actions if
necessary. We are issuing this AD to
detect and correct such cracking and
corrosion, which could lead to T/R
malfunction and, in a case of rejected
takeoff at V1 on a wet runway, a
consequent runway excursion, possibly
resulting in damage to the airplane and
injury to occupants.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2016–0076, dated April 18,
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,
PO 00000

Sfmt 4700
and –214 airplanes; and Model A321–
111, –112, –211, –212, and –213
airplanes. The MCAI states:
Several operators reported finding cracks,
during an unscheduled inspection, on the 3
o’clock and 9 o’clock pivot fittings of a
CFM56 engine’s thrust reverser (T/R).
Investigation results revealed that these
cracks were caused by a combination of
stress and fatigue effects. Further analysis
determined that only aeroplanes fitted with
CFM56–5A or CFM56–5B series engines
could be affected by this issue.
This condition, if not detected and
corrected, could lead to T/R malfunction and,
in a case of rejected take off at V1 on a wet
runway, a consequent runway excursion,
possibly resulting in damage to the aeroplane
and injury to occupants.
For the reasons described above, EASA
issued AD 2016–0068, requiring repetitive
inspections [for cracks and corrosion] of the
T/R pivot fittings at the 3 o’clock and 9
o’clock positions and, depending on findings,
accomplishment of applicable corrective
action(s).
Since that [EASA] AD was issued, it was
determined that the list of part numbers
(P/N) of affected T/R pivot fitting, as
identified in that [EASA] AD, was
incomplete.
For the reason stated above, this [EASA]
AD retains the requirements of EASA AD
2016–0068, which is superseded, but
expands the list of affected fitting P/Ns.
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–
8182.
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 Revise Repetitive Inspection
Interval
American Airlines (AA) requested
that we revise paragraph (g) of the
proposed AD to change the proposed
repetitive inspection interval for
inspecting the T/R pivot fittings from 60
months to 10 years to match certain
airworthiness limitation items (ALIs).
AA stated that aligning the inspection
interval with existing ALIs allows
accomplishment of the inspection
during a shop overhaul along with other
ALIs. AA stated that this will
significantly reduce the burden on
operators. AA explained that changing
this compliance time will not affect the
likelihood of fatigue cracking, since
fatigue effects are cycle-based and the
same cycle-threshold is maintained.
We do not agree with AA’s request.
EASA, as the State of Design Authority
for Airbus products, has determined
E:\FR\FM\06JNR1.SGM
06JNR1
Federal Register / Vol. 82, No. 107 / Tuesday, June 6, 2017 / Rules and Regulations
sradovich on DSK3GMQ082PROD with RULES
that the compliance time of 60 months
represents the maximum interval of
time allowable for the affected airplanes
to continue to safely operate. This
determination is based on the severity of
the failure and the likelihood of the
failure’s occurrence, and takes into
account the overall risk to the fleet. The
FAA and EASA worked with Airbus to
ensure that all appropriate actions are
taken at the appropriate times to
mitigate risk to the fleet. However,
under the provisions of paragraph (l)(1)
of this AD, we will consider requests for
approval of a revised inspection interval
if sufficient data are submitted to
substantiate that the inspection interval
would provide an acceptable level of
safety. We have not changed this AD in
this regard.
Request To Use Later Revisions of
Service Information
AA requested that we allow the use of
later revisions of the service information
for accomplishment of the actions
specified in paragraph (g) of the
proposed AD. AA asserted that future
revisions of the referenced service
information will have additional
analysis and insight into the design and
failure modes of the structure.
Additionally, AA pointed out that the
FAA will have an opportunity to object
to any revisions the manufacturer
proposes.
We do not agree with AA’s request.
We may not refer to any document in an
AD that does not yet exist.
In general terms, we are required by
the Office of the Federal Register (OFR)
regulations to either publish the service
document contents as part of the actual
AD language; or submit the service
document to the OFR for approval as
‘‘referenced’’ material, in which case we
may only refer to such material in the
text of an AD. The AD may refer to the
service document only if the OFR
approved it for ‘‘incorporation by
reference.’’ See 1 CFR part 51.
To allow operators to use later
revisions of the referenced document
(issued after publication of the AD),
either we must revise the AD to
reference specific later revisions, or
operators must request approval to use
later revisions as an alternative method
of compliance with this AD under the
provisions of paragraph (l)(1) of this AD.
We have not changed this AD in this
regard.
Request To Revise Service Information
Date
AA requested that we revise the
‘‘Related Service Information under 1
CFR part 51’’ section of the preamble
and paragraphs (g) and (j) of the
VerDate Sep<11>2014
18:18 Jun 05, 2017
Jkt 241001
proposed AD to correct the revision date
specified for Airbus Service Bulletin
A320–70–1003, Revision 01, dated
December 28, 2015. AA pointed out that
in the NPRM the release date is stated
as December 18, 2015, instead of
December 28, 2015.
We agree to fix the typographical
error. We have revised this final rule
accordingly.
Request To Clarify Which Service
Information Is Required for Certain
Actions
AA requested that we revise
paragraphs (g) and (h) of the proposed
AD to clarify that doing the actions in
paragraph (g) of the proposed AD in the
shop/off-wing requires only
accomplishment of Goodrich
Aerostructures Service Bulletin
RA32078–137, Rev. 3, dated March 14,
2016. AA asserted that the actions
specified in Airbus Service Bulletin
A320–70–1003, Revision 01, dated
December 28, 2015, which provides
open-up instructions for on-wing
actions, are not necessary to comply
with the proposed requirements.
We do not agree with AA’s request to
revise paragraphs (g) and (h) of this AD
to clarify the required actions. However,
we do agree to clarify the use of the
phrase ‘‘as applicable’’ in paragraph (g)
of this AD. The intent of using the
phrase ‘‘as applicable’’ in paragraph (g)
of this AD is not to authorize an
operator to accomplish either Airbus
Service Bulletin A320–70–1003,
Revision 01, dated December 28, 2015;
or Goodrich Aerostructures Service
Bulletin RA32078–137, Rev. 3, dated
March 14, 2016. Operators must
accomplish the actions in accordance
with the applicable requirements in the
Airbus service bulletin and the
Goodrich Aerostructures service
bulletin.
Goodrich Aerostructures Service
Bulletin RA32078–137, Rev. 3, dated
March 14, 2016, contains more detailed
procedures for accomplishing certain
required actions that are specified in
Airbus Service Bulletin A320–70–1003,
Revision 01, dated December 28, 2015.
Therefore, operators must use both
service bulletins to accomplish the AD
requirements.
We also note that Airbus Service
Bulletin A320–70–1003, Revision 01,
dated December 28, 2015, contains
Required for Compliance (RC) actions
and specifies only paragraphs 3.C. and
3.D. are RC procedures. The ‘‘open-up
instructions’’ in paragraph 3.B. of the
Airbus service bulletin are not RC
procedures. Those procedures and tests
that are not identified as RC may be
deviated from using accepted methods
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
25937
in accordance with the operator’s
maintenance or inspection program
without obtaining approval of an
alternative method of compliance
(AMOC), provided the procedures and
tests identified as RC can be done and
the airplane can be put back in an
airworthy condition. We have not
changed this AD in this regard.
AA also requested that we revise
paragraphs (k)(2)(i), (k)(2)(ii), and
(k)(2)(iii) of the proposed AD to permit
the use of any of the specified service
information by adding the phrase ‘‘as
applicable’’ following references to the
service information. AA asserted that
this revision would prevent any
confusion regarding off-wing
maintenance for which Airbus Service
Bulletin A320–70–1003, Revision 01,
dated December 28, 2015, will not be
needed since the T/R is not installed on
an airplane. AA stated that this revision
would align the wording in paragraph
(k) of the proposed AD with the wording
in the first sentence of paragraph (g) of
the proposed AD.
We do not agree to add ‘‘as
applicable’’ to paragraphs (k)(2)(i),
(k)(2)(ii), and (k)(2)(iii) of this AD. If an
operator wants to install a spare part,
then they still need to perform Airbus
Service Bulletin A320–70–1003,
Revision 01, dated December 28, 2015;
and Goodrich Aerostructures Service
Bulletin RA32078–137, Rev. 3, dated
March 14, 2016. For example, if a spare
met the 60-month threshold to qualify
as serviceable then operators are still
required to perform the operational test
of the thrust reversers after installation
of the fittings. We have not changed this
AD in this regard.
Request To Clarify Compliance Time in
Paragraph (h)(2) of the Proposed AD
AA requested that we revise
paragraph (h)(2) of the proposed AD to
clarify that the compliance time of 7,200
flight cycles accumulated applies to the
T/R and not to the airplane.
We agree that clarification is
necessary. The accumulated flight
cycles are on the T/R, not the airplane.
We have revised paragraph (h)(2) of this
AD accordingly.
Request To Revise or Remove Parts
Limitation Compliance Time
AA requested that we revise
paragraph (j) of the proposed AD to
remove the limitation of fixing the
unsafe condition on T/Rs prior to
installation, as of the effective date of
this AD. Rather, AA requested that we
revise the compliance times to those in
paragraph (h) of the proposed AD if it
is determined that, prior to installation,
the T/R was removed as part of an
E:\FR\FM\06JNR1.SGM
06JNR1
25938
Federal Register / Vol. 82, No. 107 / Tuesday, June 6, 2017 / Rules and Regulations
unrelated on-wing maintenance action.
AA stated that paragraph (j) of the
proposed AD puts a burden on operators
to fix the unsafe condition on the T/R
if the discrepant T/R is removed for any
maintenance reason. Additionally, AA
asserted that the proposed actions
require special inspection equipment,
inventory, consumable materials, etc.,
which are not readily available at all
stations, in addition to the necessary
labor and extensive downtime.
Alternatively, AA stated that removal of
paragraph (j) of the proposed AD would
be acceptable.
We do not agree with AA’s request.
Paragraph (j) of this AD does not require
immediate corrective action for a T/R
that is removed for any maintenance
action, unless the T/R exceeds the
thresholds specified in paragraph (j) of
this AD. EASA has determined that the
compliance time specified in paragraph
(j) of this AD should be based on the
severity of the failure, the likelihood of
the failure’s occurrence, and the overall
safety risk to the fleet. The FAA and
EASA worked with Airbus to ensure
that all appropriate action(s) are taken at
appropriate times to mitigate risk to the
fleet. This determination took into
consideration parts and special tool
availability, and planning for
accomplishment of any necessary
corrective action. Airbus did not
provide us any information related to a
short supply of parts or tools required
for accomplishment of this AD. In
addition, it is the operator’s
responsibility to plan appropriately for
actions to be taken to assure parts and
equipment are available for AD
compliance. Therefore, the FAA’s
expectation is that, as of the effective
date of this AD, operators will not
install a known unsafe part as specified
in paragraph (j) of this AD. However, if
the part is already installed and inservice, then operators may utilize the
full compliance time as allowed by this
AD. Operators have the option of
proposing an alternative compliance
time, with supportive data, in
accordance with paragraph (l)(1) of this
AD. We have not changed this AD in
this regard.
Request To Permit Flights With
Deactivated T/Rs
AA requested that we revise the
proposed AD to allow a minimum
equipment list (MEL) provision to
deactivate affected T/Rs for the
allowable duration of that MEL item
before accomplishing the corrective
actions specified in the proposed AD.
AA explained that this action would
provide an equivalent level of safety
since, during application of the MEL,
the T/Rs are deactivated and there is
never a possibility of T/R structural
failure due to cracking.
We agree with AA’s request. We have
added paragraph (i)(3) to this AD to
state that it is permissible to dispatch an
airplane equipped with a T/R pivot
fitting(s) having a part number specified
in paragraph (g)(1) or (g)(2) of this AD,
provided the limitations in Master
Minimum Equipment List Item 78–30–
01 (which provides for deactivation of
the affected T/R) have been followed.
Request To Provide a Provision for
Special Flight Permits
AA requested that the proposed AD
be revised to include an allowance for
special flight permits to allow the
operator to operate the airplane to a
location where the requirements of the
proposed AD can be accomplished.
We acknowledge the potential need
for a one-time ferry flight. Although not
specifically stated in the proposed AD,
there is no restriction prohibiting or
limiting special flight permits, as
described in Section 21.197 and Section
21.199 of the Code of Federal
Regulations (14 CFR 21.197 and 21.199).
Therefore, we have not changed this AD
regarding this issue.
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.

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 August 3, 2016 (81 FR 51142). The NPRM was prompted
by reports of cracks on the 3 o'clock and 9 o'clock pivot fittings of a
CFM56 engine's T/R. The NPRM proposed to require repetitive inspections
for cracking and corrosion of the 3 o'clock and 9 o'clock pivot
fittings of a CFM56 engine's T/R, and corrective actions if necessary.
We are issuing this AD to detect and correct such cracking and
corrosion, which could lead to T/R malfunction and, in a case of
rejected takeoff at V1 on a wet runway, a consequent runway
excursion, possibly resulting in damage to the airplane and injury to
occupants.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0076, dated April 18, 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:
Several operators reported finding cracks, during an unscheduled
inspection, on the 3 o'clock and 9 o'clock pivot fittings of a CFM56
engine's thrust reverser (T/R). Investigation results revealed that
these cracks were caused by a combination of stress and fatigue
effects. Further analysis determined that only aeroplanes fitted
with CFM56-5A or CFM56-5B series engines could be affected by this
issue.
This condition, if not detected and corrected, could lead to T/R
malfunction and, in a case of rejected take off at V1 on a wet
runway, a consequent runway excursion, possibly resulting in damage
to the aeroplane and injury to occupants.
For the reasons described above, EASA issued AD 2016-0068,
requiring repetitive inspections [for cracks and corrosion] of the
T/R pivot fittings at the 3 o'clock and 9 o'clock positions and,
depending on findings, accomplishment of applicable corrective
action(s).
Since that [EASA] AD was issued, it was determined that the list
of part numbers (P/N) of affected T/R pivot fitting, as identified
in that [EASA] AD, was incomplete.
For the reason stated above, this [EASA] AD retains the
requirements of EASA AD 2016-0068, which is superseded, but expands
the list of affected fitting P/Ns.
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-
8182.
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 Revise Repetitive Inspection Interval
American Airlines (AA) requested that we revise paragraph (g) of
the proposed AD to change the proposed repetitive inspection interval
for inspecting the T/R pivot fittings from 60 months to 10 years to
match certain airworthiness limitation items (ALIs). AA stated that
aligning the inspection interval with existing ALIs allows
accomplishment of the inspection during a shop overhaul along with
other ALIs. AA stated that this will significantly reduce the burden on
operators. AA explained that changing this compliance time will not
affect the likelihood of fatigue cracking, since fatigue effects are
cycle-based and the same cycle-threshold is maintained.
We do not agree with AA's request. EASA, as the State of Design
Authority for Airbus products, has determined
[[Page 25937]]
that the compliance time of 60 months represents the maximum interval
of time allowable for the affected airplanes to continue to safely
operate. This determination is based on the severity of the failure and
the likelihood of the failure's occurrence, and takes into account the
overall risk to the fleet. The FAA and EASA worked with Airbus to
ensure that all appropriate actions are taken at the appropriate times
to mitigate risk to the fleet. However, under the provisions of
paragraph (l)(1) of this AD, we will consider requests for approval of
a revised inspection interval if sufficient data are submitted to
substantiate that the inspection interval would provide an acceptable
level of safety. We have not changed this AD in this regard.
Request To Use Later Revisions of Service Information
AA requested that we allow the use of later revisions of the
service information for accomplishment of the actions specified in
paragraph (g) of the proposed AD. AA asserted that future revisions of
the referenced service information will have additional analysis and
insight into the design and failure modes of the structure.
Additionally, AA pointed out that the FAA will have an opportunity to
object to any revisions the manufacturer proposes.
We do not agree with AA's request. We may not refer to any document
in an AD that does not yet exist.
In general terms, we are required by the Office of the Federal
Register (OFR) regulations to either publish the service document
contents as part of the actual AD language; or submit the service
document to the OFR for approval as ``referenced'' material, in which
case we may only refer to such material in the text of an AD. The AD
may refer to the service document only if the OFR approved it for
``incorporation by reference.'' See 1 CFR part 51.
To allow operators to use later revisions of the referenced
document (issued after publication of the AD), either we must revise
the AD to reference specific later revisions, or operators must request
approval to use later revisions as an alternative method of compliance
with this AD under the provisions of paragraph (l)(1) of this AD. We
have not changed this AD in this regard.
Request To Revise Service Information Date
AA requested that we revise the ``Related Service Information under
1 CFR part 51'' section of the preamble and paragraphs (g) and (j) of
the proposed AD to correct the revision date specified for Airbus
Service Bulletin A320-70-1003, Revision 01, dated December 28, 2015. AA
pointed out that in the NPRM the release date is stated as December 18,
2015, instead of December 28, 2015.
We agree to fix the typographical error. We have revised this final
rule accordingly.
Request To Clarify Which Service Information Is Required for Certain
Actions
AA requested that we revise paragraphs (g) and (h) of the proposed
AD to clarify that doing the actions in paragraph (g) of the proposed
AD in the shop/off-wing requires only accomplishment of Goodrich
Aerostructures Service Bulletin RA32078-137, Rev. 3, dated March 14,
2016. AA asserted that the actions specified in Airbus Service Bulletin
A320-70-1003, Revision 01, dated December 28, 2015, which provides
open-up instructions for on-wing actions, are not necessary to comply
with the proposed requirements.
We do not agree with AA's request to revise paragraphs (g) and (h)
of this AD to clarify the required actions. However, we do agree to
clarify the use of the phrase ``as applicable'' in paragraph (g) of
this AD. The intent of using the phrase ``as applicable'' in paragraph
(g) of this AD is not to authorize an operator to accomplish either
Airbus Service Bulletin A320-70-1003, Revision 01, dated December 28,
2015; or Goodrich Aerostructures Service Bulletin RA32078-137, Rev. 3,
dated March 14, 2016. Operators must accomplish the actions in
accordance with the applicable requirements in the Airbus service
bulletin and the Goodrich Aerostructures service bulletin.
Goodrich Aerostructures Service Bulletin RA32078-137, Rev. 3, dated
March 14, 2016, contains more detailed procedures for accomplishing
certain required actions that are specified in Airbus Service Bulletin
A320-70-1003, Revision 01, dated December 28, 2015. Therefore,
operators must use both service bulletins to accomplish the AD
requirements.
We also note that Airbus Service Bulletin A320-70-1003, Revision
01, dated December 28, 2015, contains Required for Compliance (RC)
actions and specifies only paragraphs 3.C. and 3.D. are RC procedures.
The ``open-up instructions'' in paragraph 3.B. of the Airbus service
bulletin are not RC procedures. 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 alternative method of compliance
(AMOC), provided the procedures and tests identified as RC can be done
and the airplane can be put back in an airworthy condition. We have not
changed this AD in this regard.
AA also requested that we revise paragraphs (k)(2)(i), (k)(2)(ii),
and (k)(2)(iii) of the proposed AD to permit the use of any of the
specified service information by adding the phrase ``as applicable''
following references to the service information. AA asserted that this
revision would prevent any confusion regarding off-wing maintenance for
which Airbus Service Bulletin A320-70-1003, Revision 01, dated December
28, 2015, will not be needed since the T/R is not installed on an
airplane. AA stated that this revision would align the wording in
paragraph (k) of the proposed AD with the wording in the first sentence
of paragraph (g) of the proposed AD.
We do not agree to add ``as applicable'' to paragraphs (k)(2)(i),
(k)(2)(ii), and (k)(2)(iii) of this AD. If an operator wants to install
a spare part, then they still need to perform Airbus Service Bulletin
A320-70-1003, Revision 01, dated December 28, 2015; and Goodrich
Aerostructures Service Bulletin RA32078-137, Rev. 3, dated March 14,
2016. For example, if a spare met the 60-month threshold to qualify as
serviceable then operators are still required to perform the
operational test of the thrust reversers after installation of the
fittings. We have not changed this AD in this regard.
Request To Clarify Compliance Time in Paragraph (h)(2) of the Proposed
AD
AA requested that we revise paragraph (h)(2) of the proposed AD to
clarify that the compliance time of 7,200 flight cycles accumulated
applies to the T/R and not to the airplane.
We agree that clarification is necessary. The accumulated flight
cycles are on the T/R, not the airplane. We have revised paragraph
(h)(2) of this AD accordingly.
Request To Revise or Remove Parts Limitation Compliance Time
AA requested that we revise paragraph (j) of the proposed AD to
remove the limitation of fixing the unsafe condition on T/Rs prior to
installation, as of the effective date of this AD. Rather, AA requested
that we revise the compliance times to those in paragraph (h) of the
proposed AD if it is determined that, prior to installation, the T/R
was removed as part of an
[[Page 25938]]
unrelated on-wing maintenance action. AA stated that paragraph (j) of
the proposed AD puts a burden on operators to fix the unsafe condition
on the T/R if the discrepant T/R is removed for any maintenance reason.
Additionally, AA asserted that the proposed actions require special
inspection equipment, inventory, consumable materials, etc., which are
not readily available at all stations, in addition to the necessary
labor and extensive downtime. Alternatively, AA stated that removal of
paragraph (j) of the proposed AD would be acceptable.
We do not agree with AA's request. Paragraph (j) of this AD does
not require immediate corrective action for a T/R that is removed for
any maintenance action, unless the T/R exceeds the thresholds specified
in paragraph (j) of this AD. EASA has determined that the compliance
time specified in paragraph (j) of this AD should be based on the
severity of the failure, the likelihood of the failure's occurrence,
and the overall safety risk to the fleet. The FAA and EASA worked with
Airbus to ensure that all appropriate action(s) are taken at
appropriate times to mitigate risk to the fleet. This determination
took into consideration parts and special tool availability, and
planning for accomplishment of any necessary corrective action. Airbus
did not provide us any information related to a short supply of parts
or tools required for accomplishment of this AD. In addition, it is the
operator's responsibility to plan appropriately for actions to be taken
to assure parts and equipment are available for AD compliance.
Therefore, the FAA's expectation is that, as of the effective date of
this AD, operators will not install a known unsafe part as specified in
paragraph (j) of this AD. However, if the part is already installed and
in-service, then operators may utilize the full compliance time as
allowed by this AD. Operators have the option of proposing an
alternative compliance time, with supportive data, in accordance with
paragraph (l)(1) of this AD. We have not changed this AD in this
regard.
Request To Permit Flights With Deactivated T/Rs
AA requested that we revise the proposed AD to allow a minimum
equipment list (MEL) provision to deactivate affected T/Rs for the
allowable duration of that MEL item before accomplishing the corrective
actions specified in the proposed AD. AA explained that this action
would provide an equivalent level of safety since, during application
of the MEL, the T/Rs are deactivated and there is never a possibility
of T/R structural failure due to cracking.
We agree with AA's request. We have added paragraph (i)(3) to this
AD to state that it is permissible to dispatch an airplane equipped
with a T/R pivot fitting(s) having a part number specified in paragraph
(g)(1) or (g)(2) of this AD, provided the limitations in Master Minimum
Equipment List Item 78-30-01 (which provides for deactivation of the
affected T/R) have been followed.
Request To Provide a Provision for Special Flight Permits
AA requested that the proposed AD be revised to include an
allowance for special flight permits to allow the operator to operate
the airplane to a location where the requirements of the proposed AD
can be accomplished.
We acknowledge the potential need for a one-time ferry flight.
Although not specifically stated in the proposed AD, there is no
restriction prohibiting or limiting special flight permits, as
described in Section 21.197 and Section 21.199 of the Code of Federal
Regulations (14 CFR 21.197 and 21.199). Therefore, we have not changed
this AD regarding this issue.
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.

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
[[Page 25939]]
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.

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 adding the following new airworthiness
directive (AD):
2017-11-07 Airbus: Amendment 39-18906; Docket No. FAA-2016-8182;
Directorate Identifier 2016-NM-069-AD.
(a) Effective Date
This AD is effective July 11, 2017.
(b) Affected ADs
None.
(c) Applicability
This AD applies to the Airbus airplanes, certificated in any
category, identified in paragraphs (c)(1) through (c)(4) of this AD,
all manufacturer serial numbers.
(1) Airbus Model A318-111 and -112 airplanes.
