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 certain The Boeing Company
Model 777–300ER series airplanes. The
NPRM published in the Federal
Register on November 17, 2016 (81 FR
81021) (‘‘the NPRM’’). The NPRM was
prompted by a report that the T53 and
T52 tie rods to the tripod mount
assembly in the A2 and A3 galleys were
found unattached during a routine
production inspection of certain
airplanes before delivery. The NPRM
proposed to require an inspection of A2
and A3 galleys for the presence of the
hardware that connects the tripod
mount assembly to the tie rods in the
overhead support structure, and
corrective actions if necessary. We are
issuing this AD to detect and correct an
unconnected galley tripod mount
assembly to the tie rods in the overhead
support structure, which can cause a
galley to come loose under a high
dynamic load, causing a risk of serious
injury to passengers and the blocking of
evacuation routes.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
E:\FR\FM\05JYR1.SGM
05JYR1
30954
Federal Register / Vol. 82, No. 127 / Wednesday, July 5, 2017 / Rules and Regulations
received on the NPRM and the FAA’s
response to each comment.
Request To Clarify the Inspection Type
Boeing, Air New-Zealand (ANZ), and
American Airlines (AA) requested that
we clarify whether the required
inspection type is general visual or
detailed. The commenters noted that
Boeing Alert Service Bulletin 777–
25A0677, dated April 25, 2016, requires
a general visual inspection, while the
proposed AD would require a detailed
inspection. ANZ inquired whether the
detailed inspection was an additional
requirement or a terminology correction.
Boeing requested that we remove the
detailed inspection description in
paragraph (h) of the proposed AD and
replace it with a description of a general
visual inspection.
We agree to clarify the inspection type
required by this AD. A general visual
inspection is intended to detect obvious
irregularities; in this case, the
irregularity to be detected—a missing
pin or bolt assembly that connects the
tripod mount assembly to the applicable
tie rod—may not be obvious. A detailed
inspection is therefore most appropriate
for this situation. We have not changed
this AD in this regard.
Request To Allow an Alternative Part
AA requested that the proposed AD
allow the use of a specific alternative
washer. AA provided no justification for
this request.
We infer that AA considers the use of
alternative parts prohibited. To clarify,
substitutions are allowed under
paragraph 3.A., Note 4., of the
Accomplishment Instructions of Boeing
Alert Service Bulletin 777–25A0677,
dated April 25, 2016. Therefore, we
have not changed this AD in this regard.
Request To Add a Corrective Action
AA requested that Boeing update
Boeing Alert Service Bulletin 777–
25A0677, dated April 25, 2016, to add
a corrective action if the hardware is
missing. AA stated that the service
information specifies to confirm the
presence or absence of hardware, but
gives no corrective action if the
hardware is missing.
We do not control service bulletin
changes, and we also disagree with AA’s
characterization of the required actions.
The service information specifies
inspecting to ‘‘make sure the hardware
(i.e., pin assembly or bolt assembly) that
connects the tripod mount assembly to
the T53 tie rod is installed.’’ While
investigating this issue, Boeing found
that the hardware was present, but not
installed. Boeing has confirmed that the
service information does not need to
include corrective actions to address
missing hardware. The hardware should
be present. If it is not, operators should
install the correct hardware. We have
not changed this AD in this regard.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this AD
as proposed, except for 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.
Related Service Information Under 1
CFR Part 51
We reviewed Boeing Alert Service
Bulletin 777–25A0677, dated April 25,
2016. The service information describes
procedures for doing an inspection of
the area above the A2 and A3 galleys to
make sure the hardware (i.e., pin
assembly or bolt assembly) that
connects the tripod mount assembly to
the applicable T53 and T52 tie rods is
installed, and corrective actions. 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 4
airplanes of U.S. registry. We estimate
the following costs to comply with this
AD:
ESTIMATED COSTS

Labor cost
Inspection ........................................................
1 work-hour × $85 per hour = $85 .................
sradovich on DSK3GMQ082PROD with RULES
We have received no definitive data
that would enable us to provide cost
estimates for the on-condition actions
specified in this AD.
According to the manufacturer, some
of the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected individuals. We
do not control warranty coverage for
affected individuals. As a result, we
have included all available costs in our
cost estimate.
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
VerDate Sep<11>2014
16:11 Jul 03, 2017
Jkt 241001
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in Subtitle VII,
Part A, Subpart III, Section 44701:
‘‘General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.

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.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
For the purposes of this AD, a detailed
inspection is an intensive examination of a
specific item, installation, or assembly to
detect damage, failure, or irregularity.
Available lighting is normally supplemented
with a direct source of good lighting at an
intensity deemed appropriate. Inspection
aids such as mirror, magnifying lenses, etc.,
may be necessary. Surface cleaning and
elaborate procedures may be required.

Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain The Boeing Company
Model 777-300ER series airplanes. The NPRM published in the Federal
Register on November 17, 2016 (81 FR 81021) (``the NPRM''). The NPRM
was prompted by a report that the T53 and T52 tie rods to the tripod
mount assembly in the A2 and A3 galleys were found unattached during a
routine production inspection of certain airplanes before delivery. The
NPRM proposed to require an inspection of A2 and A3 galleys for the

Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments
[[Page 30954]]
received on the NPRM and the FAA's response to each comment.
Request To Clarify the Inspection Type
Boeing, Air New-Zealand (ANZ), and American Airlines (AA) requested
that we clarify whether the required inspection type is general visual
or detailed. The commenters noted that Boeing Alert Service Bulletin
777-25A0677, dated April 25, 2016, requires a general visual

proposed AD and replace it with a description of a general visual
inspection.
We agree to clarify the inspection type required by this AD. A
general visual inspection is intended to detect obvious irregularities;
in this case, the irregularity to be detected--a missing pin or bolt
assembly that connects the tripod mount assembly to the applicable tie
rod--may not be obvious. A detailed inspection is therefore most
appropriate for this situation. We have not changed this AD in this
regard.
Request To Allow an Alternative Part
AA requested that the proposed AD allow the use of a specific
alternative washer. AA provided no justification for this request.
We infer that AA considers the use of alternative parts prohibited.
To clarify, substitutions are allowed under paragraph 3.A., Note 4., of
the Accomplishment Instructions of Boeing Alert Service Bulletin 777-
25A0677, dated April 25, 2016. Therefore, we have not changed this AD
in this regard.
Request To Add a Corrective Action
AA requested that Boeing update Boeing Alert Service Bulletin 777-
25A0677, dated April 25, 2016, to add a corrective action if the
hardware is missing. AA stated that the service information specifies
to confirm the presence or absence of hardware, but gives no corrective
action if the hardware is missing.
We do not control service bulletin changes, and we also disagree
with AA's characterization of the required actions. The service
information specifies inspecting to ``make sure the hardware (i.e., pin
assembly or bolt assembly) that connects the tripod mount assembly to
the T53 tie rod is installed.'' While investigating this issue, Boeing
found that the hardware was present, but not installed. Boeing has
confirmed that the service information does not need to include
corrective actions to address missing hardware. The hardware should be
present. If it is not, operators should install the correct hardware.
We have not changed this AD in this regard.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed, except for 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.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin 777-25A0677, dated April
25, 2016. The service information describes procedures for doing an
inspection of the area above the A2 and A3 galleys to make sure the
hardware (i.e., pin assembly or bolt assembly) that connects the tripod
mount assembly to the applicable T53 and T52 tie rods is installed, and
corrective actions. 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 4 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection............................ 1 work-hour x $85 per $0 $85 $340
hour = $85.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all available costs in our
cost estimate.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
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.

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 adding the following new airworthiness
directive (AD):
2017-13-14 The Boeing Company: Amendment 39-18944; Docket No. FAA-
2016-9384; Directorate Identifier 2016-NM-154-AD.
(a) Effective Date
This AD is effective August 9, 2017.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 777-300ER series
airplanes, certificated in any category, as identified in Boeing
Alert Service Bulletin 777-25A0677, dated April 25, 2016.
(d) Subject
Air Transport Association (ATA) of America Code 25, Equipment/

unless already done.
(g) Inspection and Corrective Actions
Within 12 months after the effective date of this AD: Do a
detailed inspection of the area above the A2 and A3 galleys to make
sure the hardware (i.e., pin assembly or bolt assembly) that
connects the tripod mount assembly to the applicable T53 and T52 tie
rods is installed, and do all applicable corrective actions, in
accordance with the Accomplishment Instructions of Boeing Alert
Service Bulletin 777-25A0677, dated April 25, 2016. Do all
applicable corrective actions before further flight.
(h) Definition of Detailed Inspection
For the purposes of this AD, a detailed inspection is an
intensive examination of a specific item, installation, or assembly
to detect damage, failure, or irregularity. Available lighting is
normally supplemented with a direct source of good lighting at an
intensity deemed appropriate. Inspection aids such as mirror,
magnifying lenses, etc., may be necessary. Surface cleaning and
elaborate procedures may be required.
(i) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in paragraph (j) of this AD.
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
(3) An AMOC that provides an acceptable level of safety may be
used for any repair, modification, or alteration required by this AD
if it is approved by the Boeing Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the
Manager, Seattle ACO, to make those findings. To be approved, the
repair method, modification deviation, or alteration deviation must
meet the certification basis of the airplane, and the approval must
specifically refer to this AD.
(4) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(i)(4)(i) and (i)(4)(ii) of this AD apply.
(i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. If a step or substep is labeled ``RC Exempt,'' then the
RC requirement is removed from that step or substep. An AMOC is
required for any deviations to RC steps, including substeps and
identified figures.
(ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.
