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 787–8 and 787–9 airplanes. The
NPRM published in the Federal
Register on December 28, 2016 (81 FR
95536) (‘‘the NPRM’’). The NPRM was
prompted by wire harness chafing on
the EMAs for certain spoilers due to
insufficient separation with adjacent
structure. The NPRM proposed to
require replacement of affected EMAs.
We are issuing this AD to prevent
chafing and consequent wire damage
that could result in a potential source of
ignition in the flammable leakage zone
and a consequent fire or explosion.
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
Boeing indicated its support for the
intent of the NPRM.
Request To Reduce Compliance Time
The Air Line Pilots Association,
International, (ALPA), supported the
intent of the NPRM but asked that the
compliance time in the proposed AD be
reduced from 40 to 20 months. The
commenter stated that the NPRM’s 40month compliance time, combined with
the release date of Boeing Service
Bulletin B787–81205–SB270030–00,
Issue 001, dated October 22, 2015,
would provide operators in excess of 56

21JYR1
33786
Federal Register / Vol. 82, No. 139 / Friday, July 21, 2017 / Rules and Regulations
months to comply. ALPA stated that it
believes that operators have had
sufficient time to schedule the proposed
maintenance procedures, and
recommended the shorter compliance
time, which would provide an overall
timeframe of 36 months from the release
date of Boeing Service Bulletin B787–
81205–SB270030–00, Issue 001, dated
October 22, 2015, to resolve the issue.
We do not agree with the commenter’s
request to reduce the compliance time.
In developing an appropriate
compliance time for this action, we
considered the safety implications, parts
availability, and normal maintenance
schedules for timely accomplishment of
replacement of the EMAs. Further, we
arrived at the proposed compliance time
with the manufacturer’s concurrence. In
consideration of all of these factors, we
determined that the compliance time, as
proposed, represents an appropriate
interval in which the EMA can be
replaced in a timely manner within the
fleet, while still maintaining an
adequate level of safety. Most ADs,
including this one, permit operators to
accomplish the requirements of an AD
at a time earlier than the specified
compliance time; therefore, an operator
may choose to replace the EMA at any
time within the 40-month compliance
time. If additional data are presented
that would justify a shorter compliance
time, we may consider further
rulemaking on this issue. We have not
changed the AD in this regard.
Request To Extend Compliance Time
United Airlines (UA) asked that the
compliance time in the proposed AD be
extended. UA stated that considering
the extensive ground time required for
implementing the corrective action,
additional time is necessary.
We do not agree with the commenter’s
request to extend the compliance time.
UA did not suggest an alternative
compliance time. In developing an
appropriate compliance time for this
action, we considered the safety
implications, parts availability, and
normal maintenance schedules for the
timely accomplishment of the
replacement. In consideration of these
items, we have determined that a 40month compliance time will ensure an
acceptable level of safety and allow the
replacements to be done during
scheduled maintenance intervals for
most affected operators. We have not
changed the 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 Service Bulletin
B787–81205–SB270030–00, Issue 001,
dated October 22, 2015. The service
information describes procedures for
replacing affected EMAs with new
EMAs. 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 19
airplanes of U.S. registry. We estimate
the following costs to comply with this
AD:

Authority for This Rulemaking
Regulatory Findings
List of Subjects in 14 CFR Part 39
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.
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.

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 787-8 and 787-9 airplanes. The NPRM published in the Federal
Register on December 28, 2016 (81 FR 95536) (``the NPRM''). The NPRM
was prompted by wire harness chafing on the EMAs for certain spoilers
due to insufficient separation with adjacent structure. The NPRM
proposed to require replacement of affected EMAs. We are issuing this
AD to prevent chafing and consequent wire damage that could result in a
potential source of ignition in the flammable leakage zone and a
consequent fire or explosion.
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
Boeing indicated its support for the intent of the NPRM.
Request To Reduce Compliance Time
The Air Line Pilots Association, International, (ALPA), supported
the intent of the NPRM but asked that the compliance time in the
proposed AD be reduced from 40 to 20 months. The commenter stated that
the NPRM's 40-month compliance time, combined with the release date of
Boeing Service Bulletin B787-81205-SB270030-00, Issue 001, dated
October 22, 2015, would provide operators in excess of 56
[[Page 33786]]
months to comply. ALPA stated that it believes that operators have had
sufficient time to schedule the proposed maintenance procedures, and
recommended the shorter compliance time, which would provide an overall
timeframe of 36 months from the release date of Boeing Service Bulletin
B787-81205-SB270030-00, Issue 001, dated October 22, 2015, to resolve
the issue.
We do not agree with the commenter's request to reduce the
compliance time. In developing an appropriate compliance time for this
action, we considered the safety implications, parts availability, and
normal maintenance schedules for timely accomplishment of replacement
of the EMAs. Further, we arrived at the proposed compliance time with
the manufacturer's concurrence. In consideration of all of these
factors, we determined that the compliance time, as proposed,
represents an appropriate interval in which the EMA can be replaced in
a timely manner within the fleet, while still maintaining an adequate
level of safety. Most ADs, including this one, permit operators to
accomplish the requirements of an AD at a time earlier than the
specified compliance time; therefore, an operator may choose to replace
the EMA at any time within the 40-month compliance time. If additional
data are presented that would justify a shorter compliance time, we may
consider further rulemaking on this issue. We have not changed the AD
in this regard.
Request To Extend Compliance Time
United Airlines (UA) asked that the compliance time in the proposed
AD be extended. UA stated that considering the extensive ground time
required for implementing the corrective action, additional time is
necessary.
We do not agree with the commenter's request to extend the
compliance time. UA did not suggest an alternative compliance time. In
developing an appropriate compliance time for this action, we
considered the safety implications, parts availability, and normal
maintenance schedules for the timely accomplishment of the replacement.
In consideration of these items, we have determined that a 40-month
compliance time will ensure an acceptable level of safety and allow the
replacements to be done during scheduled maintenance intervals for most
affected operators. We have not changed the 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 Service Bulletin B787-81205-SB270030-00, Issue
001, dated October 22, 2015. The service information describes
procedures for replacing affected EMAs with new EMAs. 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 19 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
----------------------------------------------------------------------------------------------------------------
EMA replacement..................... 32 work-hours x $85 per \1\ $0 $2,720 $51,680
hour = $2,720 per EMA
replacement.
----------------------------------------------------------------------------------------------------------------
\1\ Parts cost is not included in the service information, but Boeing has indicated that existing parts can be
modified to become the new parts.
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.
