(c) Credit union-run tests under
NCUA supervision. After NCUA has
completed three consecutive
supervisory stress tests of a covered
credit union, the covered credit union
may, with NCUA approval, conduct the
tests described in this subpart. A
covered credit union must submit its
request to NCUA to conduct its own
stress test by November 30 for the
following annual cycle. NCUA will
approve or decline the credit union’s
request by December 31 of the year in
which the credit union submitted its
request. NCUA reserves the right to
conduct the tests described in this
section on any covered credit union at
any time. Where both NCUA and a
covered credit union have conducted
the tests, the results of NCUA’s tests
will determine whether the covered
credit union has met the requirements
of this subpart.
(d) Potential impact on capital. In
conducting stress tests under this
subpart, NCUA or the covered credit
union will estimate the following for
each scenario during each quarter of the
stress test horizon:
(1) Losses, pre-provision net revenues,
loan and lease loss provisions, and net
income; and
(2) The potential impact on the stress
test capital ratio, incorporating the
effects of any capital action over the 9quarter stress test horizon and
maintenance of an allowance for loan
losses appropriate for credit exposures
throughout the horizon. NCUA or the
covered credit union will conduct the
stress tests without assuming any risk
mitigation actions on the part of the
covered credit union, except those
existing and identified as part of the
covered credit union’s balance sheet, or
off-balance sheet positions, such as asset
sales or derivatives positions, on the
date of the stress test.
(e) Information collection. Upon
request, the covered credit union must
provide NCUA with any relevant
qualitative or quantitative information
requested by NCUA pertinent to the
stress tests under this subpart.
(f) Stress test results. NCUA will
provide each covered credit union with
the results of the stress tests by August
31 of the year in which it conducted the
tests. A credit union conducting its own
stress tests must incorporate the test
results in its capital plan.
(g) Supervisory actions. If NCUA-run
stress tests show that a covered credit
union does not have the ability to
maintain a stress test capital ratio of 5

percent or more under expected and
stressed conditions in each quarter of
the 9-quarter horizon, the credit union
must provide NCUA, by November 30 of
the calendar year in which NCUA
conducted the tests, a stress test capital
enhancement plan showing how it will
meet that target. If credit union-run
stress tests show that a covered credit
union does not have the ability to
maintain a stress test capital ratio of 5
percent or more under expected and
stressed conditions in each quarter of
the 9-quarter horizon, the credit union
must incorporate a stress test capital
enhancement plan into its capital plan.
Any affected credit union operating
without a stress test capital
enhancement plan accepted by NCUA
may be subject to supervisory actions.

redundant cabin altitude pressure
switch, replacing the aural warning
module (AWM) with a new or reworked
AWM, and changing certain wire
bundles or connecting certain
previously capped and stowed wires as
necessary. For certain airplanes, AD
2012–19–11 also required prior or
concurrent incorporation of related
design changes by modifying the
instrument panels, installing light
assemblies, modifying the wire bundles,
and installing a new circuit breaker, as
necessary. This AD was prompted by
the report of a flightcrew not receiving
an aural warning during a lack-of-cabin

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012). AD 2012–19–11
E:\FR\FM\11AUR1.SGM

48014
Federal Register / Vol. 80, No. 154 / Tuesday, August 11, 2015 / Rules and Regulations
applied to certain The Boeing Company
Model 737 airplanes. The NPRM
published in the Federal Register on
July 29, 2014 (79 FR 43983).
The NPRM was prompted by the
report of a flightcrew not receiving an
aural warning during a lack of cabin
pressurization event. The NPRM
proposed to continue to require
incorporating design changes to
improve the reliability of the cabin
altitude warning system by installing a
redundant cabin altitude pressure
switch, replacing the AWM with a new
or reworked AWM, and changing
certain wire bundles or connecting
certain previously capped and stowed
wires as necessary.
For certain airplanes, the NPRM
proposed to continue to require prior or
concurrent incorporation of related
design changes by modifying the
instrument panels, installing light
assemblies, modifying the wire bundles,
and installing a new circuit breaker, as
necessary. The NPRM also proposed to
require, for certain airplanes,
incorporating related design changes.
The NPRM also proposed, for certain
airplanes, to no longer give credit for the
prior accomplishment of certain actions.
We are issuing this AD to prevent the
loss of cabin altitude warning, which
could delay flightcrew recognition of a
lack of cabin pressurization, and could
result in incapacitation of the flightcrew
due to hypoxia (a lack of oxygen in the
body), and consequent loss of control of
the airplane.
rmajette on DSK2TPTVN1PROD with RULES
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the NPRM (79 FR 43983,
July 29, 2014) and the FAA’s response
to each comment.
Request To Use the Latest Service
Information
Boeing requested that the proposed
rule (79 FR 43983, July 29, 2014)
incorporate Boeing Special Attention
Service Bulletin 737–21–1165, Revision
3, dated July 16, 2014, and Boeing Alert
Service Bulletin 737–31A1325, Revision
2, dated June 5, 2014. Boeing stated that
it has released new service information
and the service information should be
reflected in the proposed rule.
We agree with the commenter’s
request to reference the latest service
information. We have revised this final
rule accordingly.
Boeing Alert Service Bulletin 737–
31A1325, Revision 2, dated June 5,
2014, updates reference document
names, corrects typographical errors,
and includes airplanes that were
VerDate Sep<11>2014

Jkt 235001
removed in error in an earlier revision
of the service information. The
procedures remain unchanged. In
addition, we have added paragraph (j)(2)
of this AD, to give credit for previous
actions, if those actions were performed
before the effective date of this AD using
Boeing Alert Service Bulletin 737–
31A1325, dated January 11, 2010, and
Boeing Alert Service Bulletin 737–
31A1325, Revision 1, dated July 5, 2012.
Boeing Special Attention Service
Bulletin 737–21–1165, Revision 3, dated
July 16, 2014, includes configuration
differences found by operators during
incorporation of earlier revisions of the
service information. The procedures
otherwise remain unchanged.
Request To Add an Exception to the
Proposed Rule (79 FR 43983, July 29,
2014)
An anonymous commenter requested
to add an exception to the proposed rule
(79 FR 43983, July 29, 2014). The
commenter stated that paragraphs (j)(2)
and (j)(3) of the proposed AD should
include the same exceptions for group
24 through 25 airplanes, and group 27
through 33 airplanes, as identified in
Boeing Alert Service Bulletin 737–
31A1332, Revision 4, dated October 31,
2013.
The commenter also stated that
paragraphs (i)(2) and (i)(3) of AD 2012–
19–11, Amendment 39–17206 (77 FR
60296, October 3, 2012), did not give
credit for previous actions for group 24
through 25 airplanes, and group 27
through 33 airplanes, as identified in
Boeing Alert Service Bulletin 737–
31A1332, Revision 3, dated March 28,
2012. The commenter stated that this is
because paragraph 1.C. of Boeing Alert
Service Bulletin 737–31A1332, Revision
3, dated March 28, 2012, explicitly
states that changes given in figures 48
through 50 affect wiring changes
previously accomplished in Boeing
Service Bulletin 737–24A1141; also
figures 15 through 17, and airplane line
numbers 1 through 740, are moved to a
new group 24 through 25 airplanes, and
group 27 through 33 airplanes.
The commenter stated that if an
airplane is identified in groups 24
through 25 airplanes, and group 27
through 33 airplanes, of Boeing Alert
Service Bulletin 737–31A1332, Revision
4, dated October 31, 2013, the operator
can take credit for previous actions
accomplished using Boeing Alert
Service Bulletin 737–31A1332, Revision
2, dated August 18, 2011, and Boeing
Alert Service Bulletin 737–31A1332,
Revision 1, dated June 24, 2010.
Therefore, the commenter stated that the
operator must, per the exceptions of
paragraphs (i)(2) or (i)(3) of AD 2012–

19–11, Amendment 39–17206 (77 FR
60296, October 3, 2012), re-comply with
the proposed AD once the additional
actions are taken.
We disagree with the commenter’s
request. This AD corrects an error in
paragraph (i) of AD 2012–19–11,
Amendment 39–17206 (77 FR 60296,
October 3, 2012). In AD 2012–19–11,
airplanes were identified incorrectly as
having wiring instructions that may
conflict with the corrective actions of
AD 2009–16–07, Amendment 39–15990
(74 FR 41607, August 18, 2009). Further,
this AD supersedes (i.e., ‘‘replaces’’) AD
2012–19–11, and therefore compliance
is required with this new AD only. In
addition, there are still exclusions in
this AD, but they are now identified by
line numbers—not by groups—as shown
in paragraphs (j)(1)(ii) and (j)(1)(iii) of
this AD. We have not changed this AD
in this regard.
Request To Extend the Compliance
Time
United Airlines (UAL) requested that
the compliance time for the proposed
rule (79 FR 43983, July 29, 2014) be
extended a minimum of 1 year for all
airplanes. UAL stated that this is due to
the increased scope of required testing
not documented in Boeing Special
Attention Service Bulletin 737–21–
1165, Revision 1, dated July 16, 2010, as
revised by Boeing Special Attention
Service Bulletin 737–21–1165, Revision
2, dated April 30, 2012. UAL
commented that Boeing Special
Attention Service Bulletin 737–21–
1165, Revision 2, dated April 30, 2012,
is for the removal of the junction box 46,
and additional administrative time is
required during the accomplishment of
each airplane for obtaining an alternate
method of compliance (AMOC).
UAL commented that due to the
removal of junction box 46, 43
additional operational checks must be
accomplished and are estimated to take
an additional 30 hours of elapsed time
for each airplane. UAL stated that the
estimated costs of the proposed rule (79
FR 43983, July 29, 2014) should be
revised to include an additional 30
hours for testing.
UAL also stated that multiple AMOCs
have been required for the concurrent
requirements and for airplanes affected
by AD 2013–02–05, Amendment 39–
17326 (78 FR 6202, January 30, 2013)
due to errors in the Boeing data. UAL
stated that the time necessary to seek
approved AMOCs extends the
completion time of each airplane
beyond the time allotted in the
estimated costs and can result in the
airplanes being out of service.
E:\FR\FM\11AUR1.SGM
11AUR1
Federal Register / Vol. 80, No. 154 / Tuesday, August 11, 2015 / Rules and Regulations
We disagree with the commenter’s
request. Boeing has provided its work
estimates based on average times for
accomplishing its service information
specifically to correct the unsafe
condition. The time spent to perform
additional functional checks and testing
to systems incidentally associated with
the unsafe condition in this AD and any
associated administrative actions in
carrying out all work (related to this AD)
will vary among operators.
Additionally, we do not consider the
time spent processing AMOCs when we
determine estimated costs of an AD
because of the variable occurrences,
scope of technical deviations, and
elective nature of many AMOC requests.
The estimate of labor hours provides
only a guideline for operators, and
operators are encouraged to review all
relevant work steps to create time and
cost estimates specific to their schedules
and work processes. Operators that
request AMOCs while their airplane is
in maintenance do not have to wait for
the Seattle Aircraft Certification Office
(ACO) approval before they can return
the airplane to service, provided the 72month compliance time has not passed,
and operators do not claim compliance
credit in their maintenance records until
the AMOC is received. As long as the
72-month compliance time has not been
exceeded, an AMOC is not needed;
therefore, requests for compliance time
extensions and Seattle ACO responses
to early AMOC requests have no effect
on returning an airplane to service from
an operator’s maintenance cycle.
We base AD compliance times
primarily on our assessment of safety
risk. We consider the overall risk to the
fleet, including the severity of the
failure and the likelihood of the failure’s
occurrence in development of the
compliance time for the ADs. We work
with the respective manufacturers to
ensure that all appropriate instructions
and parts are available at the
appropriate time to meet our collective
safety goals, and that those goals are
based on safety of the fleet. We have not
changed this AD in this regard.
Effect of Winglets on AD
Aviation Partners Boeing stated that
the installation of winglets per STC
ST01219SE or ST00830SE does not
affect the accomplishment of the
manufacturer’s service instructions.
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 (79 FR
43983, July 29, 2014) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (79 FR 43983,
July 29, 2014).
We also determined that these
changes will not increase the economic
48015
burden on any operator or increase the
scope of this AD.

We have 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
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

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 the specified products. The
NPRM was published in the Federal
Register on April 29, 2015 (80 FR
23741). The NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
There were a number of pre-MOD/SB 72–
7730 High Pressure Turbine (HPT) blade
failures, with some occurring within a
relatively short time. Engineering analysis
carried out by RR on those occurrences
indicates that certain pre-MOD/SB 72–7730
blades, Part Number (P/N) UL32958 and P/
N UL21691 (hereafter referred to as ‘affected
HPT blade’), with an accumulated life of
6500 flight hours (FH) since new or more,
have an increased risk of in-service failure.
This condition, if not corrected, could lead
to HPT blade failure, release of debris and
consequent (partial or complete) loss of
engine power, possibly resulting in reduced
control of the aeroplane.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (80
FR 23741, April 29, 2015).
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting this AD
as proposed.
Costs of Compliance
We estimate that this AD affects 6
engines installed on airplanes of U.S.
registry. We also estimate that it will
take about 4 hours per engine to comply
with this AD. The average labor rate is
$85 per hour. Pro-rated cost of required
parts is about $250,000 per engine.
Based on these figures, we estimate the
cost of this AD on U.S. operators to be
$1,502,040.
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:
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
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 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 to the extent that it justifies
making a regulatory distinction, 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.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2012-19-11 for
certain The Boeing Company Model 737 airplanes. AD 2012-19-11 required
incorporating design changes to improve the reliability of the cabin
altitude warning system by installing a redundant cabin altitude
pressure switch, replacing the aural warning module (AWM) with a new or
reworked AWM, and changing certain wire bundles or connecting certain
previously capped and stowed wires as necessary. For certain airplanes,
AD 2012-19-11 also required prior or concurrent incorporation of
related design changes by modifying the instrument panels, installing
light assemblies, modifying the wire bundles, and installing a new
circuit breaker, as necessary. This AD was prompted by the report of a
flightcrew not receiving an aural warning during a lack-of-cabin
pressurization event. We are issuing this AD to prevent the loss of
cabin altitude warning, which could delay flightcrew recognition of a
lack of cabin pressurization, and could result in incapacitation of the
flightcrew due to hypoxia (a lack of oxygen in the body), and
consequent loss of control of the airplane.
DATES: This AD is effective September 15, 2015.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 15,
2015.
The Director of the Federal Register approved the incorporation by
reference of certain other publications listed in this AD as of

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2012-19-11, Amendment 39-17206 (77 FR 60296,
October 3, 2012). AD 2012-19-11
[[Page 48014]]
applied to certain The Boeing Company Model 737 airplanes. The NPRM
published in the Federal Register on July 29, 2014 (79 FR 43983).
The NPRM was prompted by the report of a flightcrew not receiving
an aural warning during a lack of cabin pressurization event. The NPRM
proposed to continue to require incorporating design changes to improve
the reliability of the cabin altitude warning system by installing a
redundant cabin altitude pressure switch, replacing the AWM with a new
or reworked AWM, and changing certain wire bundles or connecting
certain previously capped and stowed wires as necessary.
For certain airplanes, the NPRM proposed to continue to require
prior or concurrent incorporation of related design changes by
modifying the instrument panels, installing light assemblies, modifying
the wire bundles, and installing a new circuit breaker, as necessary.
The NPRM also proposed to require, for certain airplanes, incorporating
related design changes. The NPRM also proposed, for certain airplanes,
to no longer give credit for the prior accomplishment of certain
actions. We are issuing this AD to prevent the loss of cabin altitude
warning, which could delay flightcrew recognition of a lack of cabin
pressurization, and could result in incapacitation of the flightcrew
due to hypoxia (a lack of oxygen in the body), and consequent loss of
control of the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM (79
FR 43983, July 29, 2014) and the FAA's response to each comment.
Request To Use the Latest Service Information
Boeing requested that the proposed rule (79 FR 43983, July 29,
2014) incorporate Boeing Special Attention Service Bulletin 737-21-
1165, Revision 3, dated July 16, 2014, and Boeing Alert Service
Bulletin 737-31A1325, Revision 2, dated June 5, 2014. Boeing stated
that it has released new service information and the service
information should be reflected in the proposed rule.
We agree with the commenter's request to reference the latest
service information. We have revised this final rule accordingly.
Boeing Alert Service Bulletin 737-31A1325, Revision 2, dated June
5, 2014, updates reference document names, corrects typographical
errors, and includes airplanes that were removed in error in an earlier
revision of the service information. The procedures remain unchanged.
In addition, we have added paragraph (j)(2) of this AD, to give credit
for previous actions, if those actions were performed before the
effective date of this AD using Boeing Alert Service Bulletin 737-
31A1325, dated January 11, 2010, and Boeing Alert Service Bulletin 737-
31A1325, Revision 1, dated July 5, 2012.
Boeing Special Attention Service Bulletin 737-21-1165, Revision 3,
dated July 16, 2014, includes configuration differences found by
operators during incorporation of earlier revisions of the service
information. The procedures otherwise remain unchanged.
Request To Add an Exception to the Proposed Rule (79 FR 43983, July 29,
2014)
An anonymous commenter requested to add an exception to the
proposed rule (79 FR 43983, July 29, 2014). The commenter stated that
paragraphs (j)(2) and (j)(3) of the proposed AD should include the same
exceptions for group 24 through 25 airplanes, and group 27 through 33
airplanes, as identified in Boeing Alert Service Bulletin 737-31A1332,
Revision 4, dated October 31, 2013.
The commenter also stated that paragraphs (i)(2) and (i)(3) of AD
2012-19-11, Amendment 39-17206 (77 FR 60296, October 3, 2012), did not
give credit for previous actions for group 24 through 25 airplanes, and
group 27 through 33 airplanes, as identified in Boeing Alert Service
Bulletin 737-31A1332, Revision 3, dated March 28, 2012. The commenter
stated that this is because paragraph 1.C. of Boeing Alert Service
Bulletin 737-31A1332, Revision 3, dated March 28, 2012, explicitly
states that changes given in figures 48 through 50 affect wiring
changes previously accomplished in Boeing Service Bulletin 737-24A1141;
also figures 15 through 17, and airplane line numbers 1 through 740,
are moved to a new group 24 through 25 airplanes, and group 27 through
33 airplanes.
The commenter stated that if an airplane is identified in groups 24
through 25 airplanes, and group 27 through 33 airplanes, of Boeing
Alert Service Bulletin 737-31A1332, Revision 4, dated October 31, 2013,
the operator can take credit for previous actions accomplished using
Boeing Alert Service Bulletin 737-31A1332, Revision 2, dated August 18,
2011, and Boeing Alert Service Bulletin 737-31A1332, Revision 1, dated
June 24, 2010. Therefore, the commenter stated that the operator must,
per the exceptions of paragraphs (i)(2) or (i)(3) of AD 2012-19-11,
Amendment 39-17206 (77 FR 60296, October 3, 2012), re-comply with the
proposed AD once the additional actions are taken.
We disagree with the commenter's request. This AD corrects an error
in paragraph (i) of AD 2012-19-11, Amendment 39-17206 (77 FR 60296,
October 3, 2012). In AD 2012-19-11, airplanes were identified
incorrectly as having wiring instructions that may conflict with the
corrective actions of AD 2009-16-07, Amendment 39-15990 (74 FR 41607,
August 18, 2009). Further, this AD supersedes (i.e., ``replaces'') AD
2012-19-11, and therefore compliance is required with this new AD only.
In addition, there are still exclusions in this AD, but they are now
identified by line numbers--not by groups--as shown in paragraphs
(j)(1)(ii) and (j)(1)(iii) of this AD. We have not changed this AD in
this regard.
Request To Extend the Compliance Time
United Airlines (UAL) requested that the compliance time for the
proposed rule (79 FR 43983, July 29, 2014) be extended a minimum of 1
year for all airplanes. UAL stated that this is due to the increased
scope of required testing not documented in Boeing Special Attention
Service Bulletin 737-21-1165, Revision 1, dated July 16, 2010, as
revised by Boeing Special Attention Service Bulletin 737-21-1165,
Revision 2, dated April 30, 2012. UAL commented that Boeing Special
Attention Service Bulletin 737-21-1165, Revision 2, dated April 30,
2012, is for the removal of the junction box 46, and additional
administrative time is required during the accomplishment of each
airplane for obtaining an alternate method of compliance (AMOC).
UAL commented that due to the removal of junction box 46, 43
additional operational checks must be accomplished and are estimated to
take an additional 30 hours of elapsed time for each airplane. UAL
stated that the estimated costs of the proposed rule (79 FR 43983, July
29, 2014) should be revised to include an additional 30 hours for
testing.
UAL also stated that multiple AMOCs have been required for the
concurrent requirements and for airplanes affected by AD 2013-02-05,
Amendment 39-17326 (78 FR 6202, January 30, 2013) due to errors in the
Boeing data. UAL stated that the time necessary to seek approved AMOCs
extends the completion time of each airplane beyond the time allotted
in the estimated costs and can result in the airplanes being out of
service.
[[Page 48015]]
We disagree with the commenter's request. Boeing has provided its
work estimates based on average times for accomplishing its service
information specifically to correct the unsafe condition. The time
spent to perform additional functional checks and testing to systems
incidentally associated with the unsafe condition in this AD and any
associated administrative actions in carrying out all work (related to
this AD) will vary among operators. Additionally, we do not consider
the time spent processing AMOCs when we determine estimated costs of an
AD because of the variable occurrences, scope of technical deviations,
and elective nature of many AMOC requests.
The estimate of labor hours provides only a guideline for
operators, and operators are encouraged to review all relevant work
steps to create time and cost estimates specific to their schedules and
work processes. Operators that request AMOCs while their airplane is in
maintenance do not have to wait for the Seattle Aircraft Certification
Office (ACO) approval before they can return the airplane to service,
provided the 72-month compliance time has not passed, and operators do
not claim compliance credit in their maintenance records until the AMOC
is received. As long as the 72-month compliance time has not been
exceeded, an AMOC is not needed; therefore, requests for compliance
time extensions and Seattle ACO responses to early AMOC requests have
no effect on returning an airplane to service from an operator's
maintenance cycle.
We base AD compliance times primarily on our assessment of safety
risk. We consider the overall risk to the fleet, including the severity
of the failure and the likelihood of the failure's occurrence in
development of the compliance time for the ADs. We work with the
respective manufacturers to ensure that all appropriate instructions
and parts are available at the appropriate time to meet our collective
safety goals, and that those goals are based on safety of the fleet. We
have not changed this AD in this regard.
Effect of Winglets on AD
Aviation Partners Boeing stated that the installation of winglets
per STC ST01219SE or ST00830SE does not affect the accomplishment of
the manufacturer's service instructions.
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 (79 FR 43983, July 29, 2014) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 43983, July 29, 2014).
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:
Boeing Alert Service Bulletin 737-31A1325, Revision 2,
dated June 5, 2014.
Boeing Alert Service Bulletin 737-31A1332, Revision 4,

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 48016]]
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 have 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 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.
