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 airplanes. The NPRM published in the Federal Register on
June 3, 2016 (81 FR 35655) (``the NPRM''). The NPRM was prompted by a
report that the grounding jumpers between the ECS bracket and the CRN
straps near passenger 1 left and 1 right entry doors were not bonded
correctly during manufacturing. The NPRM proposed to require changing
the configuration of the grounding jumpers connecting the ECS brackets
and CRN straps; measuring the bond resistance; and doing related
investigative and corrective actions if necessary. We are issuing this
AD to prevent an incorrectly bonded jumper between the ECS bracket and
the CRN strap, which does not provide proper grounding to the door
frames at doors 1 left and 1 right. If a fault occurs, an electrical
shock hazard can exist and could result in serious or fatal injury to
passengers and flight crew.
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 stated that it concurs with the content of the NPRM. United
Airlines (UAL) stated that the 12-month compliance time is a safe and
reasonable timeframe.
Requests To Reference New Service Information and Add Credit
All Nippon Airways and UAL requested that we revise the NPRM to
reference Boeing Service Bulletin B787-81205-SB530025-00, Issue 002,
dated June 2, 2016 (``B787-81205-SB530025-00 Issue 002''), and give
credit for actions accomplished using Boeing Service Bulletin B787-
81205-SB530025-00, Issue 001, dated July 17, 2014 (``B787-81205-
SB530025-00 Issue 001'').
We agree with the commenters' requests. B787-81205-SB530025-00
Issue 002 clarifies instructions and specifies the category of fay seal
application. No additional work is required by B787-81205-SB530025-00
Issue 002. B787-81205-SB530025-00 Issue 002 has steps that are labeled
as Required for Compliance (RC).
We have revised paragraphs (c) and (g) of this AD to reference
B787-81205-SB530025-00 Issue 002, and added new paragraph (h) of this
AD to provide credit for actions accomplished prior to the effective
date of this AD using B787-81205-SB530025-00 Issue 001. We have
redesignated subsequent paragraphs accordingly. We have added new
paragraph (i)(4) of this AD to address the steps marked RC in B787-
81205-SB530025-00 Issue 002.
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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> 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.
Related Service Information Under 1 CFR Part 51
We reviewed B787-81205-SB530025-00 Issue 002. The service
information describes procedures for changing the configuration of the
grounding jumpers connecting the ECS brackets and CRN straps; measuring
the bond resistance; and related investigative and corrective actions
if necessary. 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 6 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
----------------------------------------------------------------------------------------------------------------
Installation........................ 6 work-hours x $85 per $100 $610 $3,660
hour = $510.
----------------------------------------------------------------------------------------------------------------
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 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.
[[Page 83667]]
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.

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.
