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 The Boeing Company Model
777 airplanes. The NPRM published in
the Federal Register on February 18,
2016 (81 FR 8164) (‘‘the NPRM’’). The
NPRM was prompted by a report of an
incident involving a landing in which
the pilots needed to input corrections
due to airplane yaw and roll to the right;
the MLG aft trunnion pin was later
found to be fractured. The NPRM
proposed to require identification and
replacement of certain MLG aft trunnion
pins. We are issuing this AD to prevent
a fractured MLG aft trunnion pin, which
could result in collapse of the MLG and
consequent loss of control of the
airplane during landing.

Federal Register / Vol. 81, No. 166 / Friday, August 26, 2016 / Rules and Regulations
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.
Support for the NPRM
Three commenters indicated their
support for the NPRM.
Request To Update the Cost Section
One commenter, Gilles Oriot, asked
that we update the cost estimate to
reflect the costs shown in Boeing
Information Notice 777–32A0103 IN 03,
dated February 2, 2015.
We agree with the commenter and
have updated the Costs of Compliance
to reflect the updated information.
Request To Add to Credit Information
The Boeing Company, American
Airlines, Air France, Korean Air, Etihad
Airways, and All Nippon Airways
requested that we allow installation of
pins with serial numbers beginning with
‘‘EGL’’ or ‘‘MAL’’ that have been
inspected previously but were not
marked ‘‘BASE METAL INSPECTED’’ to
fulfill the requirements of the proposed
AD. The commenters stated that the
previous inspection may have been
done as part of a previous overhaul or
required inspection using other service
information that did not specify to mark
‘‘BASE METAL INSPECTED.’’ The
commenters also stated that the actions
specified in the service information are
consistent with the requirements of the
proposed AD. The commenters
suggested various changes in order to
allow installation of these parts.
58819
We acknowledge that previous
inspections may have been done as part
of an overhaul or previous service
requests, but we do not agree with the
suggested changes. We disagree because
providing credit for the inspections
required by this AD undermines the
level of record review required by this
AD for compliance, cannot ensure that
the various actions taken for each pin
are the same actions required by this
AD, and may not provide an acceptable
level of safety equivalent to this AD.
Operators that would like credit for the
actions performed before the effective
date of this AD may request approval of
an alternative method of compliance
(AMOC). The request should include a
list of affected pin serial numbers, the
airplane on which each pin is currently
installed (if applicable), and the actions
that were performed for each pin with
applicable service information. We have
not changed this final rule regarding
this issue.
crew. We recommend that the
commenter work with the manufacturer
to identify a suitable method of
compliance for future revision of the
service information. We have not
changed this final rule regarding this
issue.
Request To Allow Alternative Part
Marking
FedEx requested that we allow the
suffix ‘‘BMI’’ to be allowed for marking
the pins. FedEx stated that its record
keeping system can only track unique
part number and serial number
combinations; it is not capable of
tracking the additional ‘‘BASE METAL
INSPECTED’’ marking.
We disagree with the commenter’s
request. We disagree because pins can
be rotated among other airplanes and
operators. Operators need to be
consistent with how the pins are
identified to comply with this AD and
ensure the safety of passengers and
We reviewed Boeing Alert Service
Bulletin 777–32A0103, Revision 1,
dated December 10, 2015. The service
information describes procedures for
identifying and replacing certain MLG
aft trunnion pins. 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.
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.

AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
The Boeing Company Model 787–8
airplanes. This AD requires a one-time
inspection of the engine pylon wiring
bracket on the left wing for the presence
of an existing corner relief fillet, and
corrective action if necessary. This AD
was prompted by a report indicating
that the engine pylon wiring bracket on
certain airplanes was missing a corner
relief fillet, which could result in stress
concentration and cracking in the
engine pylon wiring bracket. We are
issuing this AD to detect and correct
cracking in the engine pylon wiring
bracket. Such cracking could result in
damage to adjacent power feeders,
subsequent electrical arcing in a
flammable leakage zone, and
consequent uncontrollable fire.
DATES: This AD is effective September
12, 2016.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of September 12, 2016.
We must receive comments on this

certain airplanes is missing a corner
relief fillet, because the engineering
graphics for the engine pylon wiring
bracket located on the left wing did not
contain the corner relief fillet. A missing
corner relief fillet could result in stress
concentration and cracking in the
bracket. The engineering graphics were
subsequently revised to add the corner
relief fillet, but the engine pylon wiring
bracket part number was not changed.
Therefore, brackets with and without an
existing corner relief fillet have the
same bracket part number. We are
issuing this AD to prevent cracking in
the engine pylon wiring bracket. Such
cracking could result in damage to
adjacent power feeders, subsequent
electrical arcing in a flammable leakage
zone, and consequent uncontrollable
fire.
Related Service Information Under
1 CFR Part 51
We reviewed Boeing Alert Service
Bulletin B787–81205–SB570012–00,
Issue 001, dated March 14, 2013. The
service information describes
procedures for a one-time inspection of
the engine pylon wiring bracket on the
left wing for the presence of existing
corner relief fillets, re-identification of
any bracket with an existing corner
relief fillet, and replacement of any
bracket without an existing corner relief
fillet. 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.
FAA’s Determination
We are issuing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
AD Requirements
This AD requires accomplishing the
actions specified in the service
information described previously.
FAA’s Justification and Determination
of the Effective Date
Currently, there are no domestic
operators of the affected airplanes on
the U.S. Register. Therefore, we find
that notice and opportunity for prior
public comment are unnecessary and
that good cause exists for making this
amendment effective in less than 30
days.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 777 airplanes. This AD was prompted by a report of
an incident involving a landing in which the pilots needed to input
corrections due to airplane yaw and roll to the right; the main landing
gear (MLG) aft trunnion pin was later found to be fractured. This AD
requires identification and replacement of certain MLG aft trunnion
pins. We are issuing this AD to prevent a fractured MLG aft trunnion
pin, which could result in collapse of the MLG and consequent loss of
control of the airplane during landing.
DATES: This AD is effective September 30, 2016.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September
30, 2016.

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 The Boeing Company
Model 777 airplanes. The NPRM published in the Federal Register on
February 18, 2016 (81 FR 8164) (``the NPRM''). The NPRM was prompted by
a report of an incident involving a landing in which the pilots needed
to input corrections due to airplane yaw and roll to the right; the MLG
aft trunnion pin was later found to be fractured. The NPRM proposed to
require identification and replacement of certain MLG aft trunnion
pins. We are issuing this AD to prevent a fractured MLG aft trunnion
pin, which could result in collapse of the MLG and consequent loss of
control of the airplane during landing.
[[Page 58819]]
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.
Support for the NPRM
Three commenters indicated their support for the NPRM.
Request To Update the Cost Section
One commenter, Gilles Oriot, asked that we update the cost estimate
to reflect the costs shown in Boeing Information Notice 777-32A0103 IN
03, dated February 2, 2015.
We agree with the commenter and have updated the Costs of
Compliance to reflect the updated information.
Request To Add to Credit Information
The Boeing Company, American Airlines, Air France, Korean Air,
Etihad Airways, and All Nippon Airways requested that we allow
installation of pins with serial numbers beginning with ``EGL'' or
``MAL'' that have been inspected previously but were not marked ``BASE
METAL INSPECTED'' to fulfill the requirements of the proposed AD. The
commenters stated that the previous inspection may have been done as
part of a previous overhaul or required inspection using other service
information that did not specify to mark ``BASE METAL INSPECTED.'' The
commenters also stated that the actions specified in the service
information are consistent with the requirements of the proposed AD.
The commenters suggested various changes in order to allow installation
of these parts.
We acknowledge that previous inspections may have been done as part
of an overhaul or previous service requests, but we do not agree with
the suggested changes. We disagree because providing credit for the
inspections required by this AD undermines the level of record review
required by this AD for compliance, cannot ensure that the various
actions taken for each pin are the same actions required by this AD,
and may not provide an acceptable level of safety equivalent to this
AD. Operators that would like credit for the actions performed before
the effective date of this AD may request approval of an alternative
method of compliance (AMOC). The request should include a list of
affected pin serial numbers, the airplane on which each pin is
currently installed (if applicable), and the actions that were
performed for each pin with applicable service information. We have not
changed this final rule regarding this issue.
Request To Allow Alternative Part Marking
FedEx requested that we allow the suffix ``BMI'' to be allowed for
marking the pins. FedEx stated that its record keeping system can only
track unique part number and serial number combinations; it is not
capable of tracking the additional ``BASE METAL INSPECTED'' marking.
We disagree with the commenter's request. We disagree because pins
can be rotated among other airplanes and operators. Operators need to
be consistent with how the pins are identified to comply with this AD
and ensure the safety of passengers and crew. We recommend that the
commenter work with the manufacturer to identify a suitable method of
compliance for future revision of the service information. We have not
changed this final rule 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 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 777-32A0103, Revision 1,
dated December 10, 2015. The service information describes procedures
for identifying and replacing certain MLG aft trunnion pins. 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 123 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........................ 2 work-hours x $85 per $0 $170 $20,910
hour = $170.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the inspection. We have
no way of determining the number of aircraft that might need this
repair:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replacement of aft trunnion pin........... 211 work-hours x $85 per hour = $5,291 $23,226
$17,935.
----------------------------------------------------------------------------------------------------------------
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
[[Page 58820]]
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.
