Discussion
Boeing discovered that the wire
harnesses on the EMAs for spoilers 4, 5,
10, and 11 do not have sufficient
separation with the adjacent structure.
Subsequent checks found that
approximately 30 percent of
undelivered airplanes at Boeing had the
similar wire harness separation issue on
the spoiler EMAs. One operator also
reported that the EMA wire harness was
95537
in contact with adjacent structure, but
no damage was found. Analysis
indicates that the wire harness
separation is reduced to its minimum
with the flaps fully extended and the
spoiler fully drooped; this is where the
chafing most likely occurs if the wire
harness does not have sufficient
separation. This condition, if not
corrected, could result in chafing that
would cause wire damage that could
result in a potential source of ignition in
the flammable leakage zone and a
consequent fire or explosion.
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.
FAA’s Determination
We are proposing 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.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
the service information described
previously. For information on the
procedures and compliance times, see
this service information at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2016–
9516.
Costs of Compliance
We estimate that this proposed AD
affects 19 airplanes of U.S. registry. We
estimate the following costs to comply
with this proposed AD:

Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
VerDate Sep<11>2014
18:33 Dec 27, 2016
Jkt 241001
section 106, describes the authority of
the FAA Administrator. Subtitle VII:
Aviation Programs, describes in more
PO 00000
Frm 00042
Fmt 4702
Sfmt 4702
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in Subtitle VII,
E:\FR\FM\28DEP1.SGM
28DEP1
95538
Federal Register / Vol. 81, No. 249 / Wednesday, December 28, 2016 / Proposed Rules
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.
(b) Affected ADs
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 proposed regulation:
(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, 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.
(e) Unsafe Condition
This AD was prompted by wire harness
chafing on the electro-mechanical actuators
(EMAs) for certain spoilers due to
insufficient separation with adjacent
structure. We are issuing this AD to prevent
chafing that would cause wire damage that
could result in a potential source of ignition
in the flammable leakage zone and a
consequent fire or explosion.

Discussion
Boeing discovered that the wire harnesses on the EMAs for spoilers
4, 5, 10, and 11 do not have sufficient separation with the adjacent
structure. Subsequent checks found that approximately 30 percent of
undelivered airplanes at Boeing had the similar wire harness separation
issue on the spoiler EMAs. One operator also reported that the EMA wire
harness was in contact with adjacent structure, but no damage was
found. Analysis indicates that the wire harness separation is reduced
to its minimum with the flaps fully extended and the spoiler fully
drooped; this is where the chafing most likely occurs if the wire
harness does not have sufficient separation. This condition, if not
corrected, could result in chafing that would cause wire damage that
could result in a potential source of ignition in the flammable leakage
zone and a consequent fire or explosion.
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.
FAA's Determination
We are proposing 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.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in the service information described previously. For information on the
procedures and compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9516.
Costs of Compliance
We estimate that this proposed AD affects 19 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
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 are 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,
[[Page 95538]]
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(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, 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.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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):
The Boeing Company: Docket No. FAA-2016-9516; Directorate Identifier
2016-NM-053-AD.
(a) Comments Due Date
We must receive comments by February 13, 2017.
(b) Affected ADs
None.
(c) Applicability
This AD applies to The Boeing Company Model 787-8 and 787-9
airplanes, certificated in any category, as identified in Boeing
Service Bulletin B787-81205-SB270030-00, Issue 001, dated October
22, 2015.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
controls.
(e) Unsafe Condition
This AD was prompted by wire harness chafing on the electro-
mechanical actuators (EMAs) for certain spoilers due to insufficient
separation with adjacent structure. We are issuing this AD to
prevent chafing that would cause wire damage that could result in a
potential source of ignition in the flammable leakage zone and a
consequent fire or explosion.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) EMA Replacement
Within 40 months after the effective date of this AD, replace
the EMAs with new EMAs, in accordance with the Accomplishment
Instructions of Boeing Service Bulletin B787-81205-SB270030-00,
Issue 001, dated October 22, 2015.
(h) 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 (i)(1) 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
(h)(4)(i) and (h)(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 sub-step is labeled ``RC Exempt,'' then
the RC requirement is removed from that step or sub-step. 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.
