Jkt 247001
The U.S.
Nuclear Regulatory Commission has
issued a standard design approval (SDA)
to Korea Electric Power Corporation and
Korea Hydro & Nuclear Power Co., Ltd
(KEPCO/KHNP) for the advanced power
reactor 1400 (APR1400) standard design
under Subpart E, ‘‘Standard Design
Approvals,’’ of title 10 of the Code of
Federal Regulations (10 CFR) part 52,
‘‘Licenses, Certifications, and Approvals
for Nuclear Power Plants.’’ This SDA
allows the APR1400 standard design to
be referenced in an application for a
construction permit or operating license
under 10 CFR part 50, ‘‘Domestic
Licensing of Production and Utilization
Facilities,’’ or an application for a
combined license or manufacturing
license under 10 CFR part 52. In
addition, the Commission has issued the
final safety evaluation report (FSER)
(ADAMS Accession No. ML18087A364)
that supports issuance of the SDA.
Issuance of this SDA signifies
completion of the NRC staff’s technical
review of KEPCO/KHNP’s APR1400
design. The NRC staff performed its
technical review of the APR1400 design
control document in accordance with
the standards for review of standard
design approval applications set forth in
10 CFR 52.139, ‘‘Standards for Review
of Applications.’’
On the basis of its evaluation and
independent analyses, as described in
the FSER, the NRC staff concludes that
KEPCO/KHNP’s application for
standard design approval meets the
applicable portions of 10 CFR 52.137,
‘‘Content of Applications; Technical
Information,’’ and the review standards
identified in 10 CFR 52.139.
Copies of the APR1400 FSER and
SDA have been placed in the NRC’s
Public Document Room, One White
Flint North, 11555 Rockville Pike,
Rockville, MD 20852, for review and
copying by interested persons.

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
737–600, –700, –700C, –800, –900, and
–900ER series airplanes; Model 757
airplanes; and Model 767 airplanes. The
NPRM published in the Federal
Register on March 9, 2017 (82 FR
13073). The NPRM was prompted by
reports of latently failed MOV actuators
of the fuel shutoff valves. The NPRM
proposed to require replacing certain
MOV actuators of the fuel shutoff valves
for the left and right engines (on all
airplanes) and of the APU fuel shutoff
valve (on Model 757 and Model 767
airplanes); and revising the maintenance
or inspection program, as applicable, to
incorporate certain AWLs.
We subsequently issued a
supplemental NPRM (SNPRM) to amend
14 CFR part 39 by adding an AD that
would apply to all Model 737 airplanes,
excluding Model 737–100, –200, –200C,
–300, –400, and –500 series airplanes;
and all Model 757 and 767 airplanes.
The SNPRM published in the Federal
Register on April 3, 2018 (83 FR 14207).
The SNPRM proposed to add Model
737–8 airplanes and future Model 737
airplanes to the applicability.
We are issuing this AD to address a
latent failure of the actuator for the
engine or APU fuel shutoff valves,
which could result in the inability to
shut off fuel to the engine or the APU,
and, in case of certain engine or APU
fires, could result in structural failure.
Comments
We gave the public the opportunity to
participate in developing this final rule.
The following presents the comments
VerDate Sep<11>2014
19:54 Oct 10, 2018
Jkt 247001
received on the SNPRM and the FAA’s
response to each comment.
Request To Exclude Model 737–8 and
Future Model 737
Boeing requested that we revise the
proposed AD (in the SNPRM) to exclude
Model 737–8 airplanes and future
Model 737 airplanes, because MOV
actuator part number MA30A1017
(Boeing P/N S343T003–76) is the only
certified MOV actuator for use on any
future Model 737 airplanes as
documented in the drawings and
Illustrated Parts Catalog (IPC). The
commenter stated that using
airworthiness limitations to prohibit the
use of parts with AD restrictions on one
minor model series (Model 737 next
generation (NG) airplanes) from being
used on a different minor model series
(Model 737–8 and future Model 737
airplanes) that does not allow the use of
the restricted parts is unnecessary and
implies that certified configurations and
ADs can be overridden via an Advisory
Circular (AC) or other means.
We disagree with the commenter’s
request. The MOV actuator currently
allowed on Model 737–8 and 737–9
airplanes, part number MA30A1017
(Boeing P/N S343T003–76), is the only
part number certificated on those
models, as documented in the
manufacturer’s drawings. However,
manufacturer’s proprietary drawings are
not readily available to all affected
operators, and there is no prohibition
against installing MOV actuator part
numbers that were determined unsafe in
this AD. We have been informed by
operators that the practice of rotating
physically interchangeable parts among
airplanes is widespread, and even a key
part of their operations. In the absence
of an AD or AWL that restricts the
installation of the affected parts, we
cannot be assured that the unsafe
condition will not be introduced to
Model 737–8, 737–9, and future 737
airplanes. In addition, ACs are advisory
in nature and do not include mandatory
actions. Therefore, ACs do not take
precedence over ADs. We have not
changed this AD regarding this issue.
Request To Remove Requirement To
Revise Maintenance Program
Boeing requested that we remove
paragraph (j) of the proposed AD and
revise FAA AC 120–77 or other
applicable advisory material to preclude
installation of equipment that both
Boeing and the FAA have determined
cause a potential safety issue, against
certified configurations. Boeing
suggested that listing parts that are not
approved for use on a given model sets
a precedent that can become
PO 00000
Frm 00005
Fmt 4700
Sfmt 4700
51305
unmanageable, and that identifying
parts that are acceptable for a given
airplane and installation position is a
more explicit and manageable approach.
Boeing added that the use of AWLs to
prohibit AD-driven part installations is
unnecessary and implies that certified
configurations and ADs can be
overridden via an AC or other means.
We disagree with the commenter’s
request. The FAA is currently
considering revising AC 120–77 to help
prevent the rotation of parts as a minor
alteration. However, ACs are advisory in
nature and do not include mandatory
actions. Therefore, ACs cannot prohibit
the installation of unsafe equipment,
and they do not take precedence over
ADs. In addition, the practice of rotating
parts is widespread, and revising the AC
will not improve the situation in a
timely manner. Certain MOV actuator
part numbers have been identified to be
unsafe for installation at certain
locations. Since those part numbers
continue to be available and acceptable
for installation at certain other
locations, we consider the use of AWLs
to prohibit specific parts installation to
be a reasonable way to address the
safety concern in a timely manner. We
have not changed this AD regarding this
issue.
Request To Clarify Affected Part
Numbers
FedEx requested that we revise
paragraphs (h)(2) and (h)(3) of the
proposed AD (in the SNPRM) to state
that no replacement is necessary if the
MOV actuator part number is one of the
following alternative part numbers: AV–
31–1 (Boeing P/N S343T003–111),
MA11A1265 (Boeing P/N S343T003–
14), or MA11A1265–1 (Boeing P/N
S343T003–41). FedEx stated that the
service information specified in
paragraphs (h)(2) and (h)(3) of the
proposed AD (in the SNPRM) explicitly
state that those alternative MOV
actuator part numbers are acceptable
substitutes for P/N MA30A1017 (Boeing
P/N S343T003–76).
We disagree with the commenter’s
request. However, we agree to clarify the
requirements of paragraphs (h)(2) and
(h)(3) of this AD. Paragraphs (h)(2) and
(h)(3) of this AD require replacement of
MOV actuator P/N MA20A2027 (Boeing
P/N S343T003–56) and P/N
MA30A1001 (Boeing P/N S343T003–66)
with an acceptable MOV actuator part
number. Those paragraphs do not state
or imply that MOV actuator P/N AV–
31–1 (Boeing P/N S343T003–111), P/N
MA11A1265 (Boeing P/N S343T003–
14), or P/N MA11A1265–1 (Boeing P/N
S343T003–41) must be replaced.
Therefore, we consider that adding the
E:\FR\FM\11OCR1.SGM
11OCR1
51306
Federal Register / Vol. 83, No. 197 / Thursday, October 11, 2018 / Rules and Regulations
proposed statement is unnecessary. We
have not changed this AD regarding this
issue.
Request To Add a Terminating Action
Provision
FedEx requested that we revise
paragraphs (i)(2) and (i)(3) of the
proposed AD (in the SNPRM) to state
that the actuator installation would
terminate the daily functional checks
required by AWLs 28–AWL–ENG and
28–AWL–APU. The commenter added
that installation of MOV actuator part
number MA30A1017 (Boeing P/N
S343T003–76) or an acceptable
alternative part number should
substantially increase the safety value.
We disagree with the commenter’s
request. We have determined that
accomplishing the applicable
maintenance or inspection program
revisions specified in paragraph (j) of
this AD are the appropriate terminating
actions. As discussed previously in the
preamble of the SNPRM, we included
the conditions (accomplishing the
applicable maintenance or inspection
program revisions) that would terminate
the requirements of AD 2015–21–10,
Amendment 39–18303 (80 FR 65130,
October 26, 2015); AD 2015–19–04,
Amendment 39–18267 (80 FR 55505,
September 16, 2015); and AD 2015–21–
09, Amendment 39–18302 (80 FR
65121, October 26, 2015). Those ADs
require incorporation of the AWLs that
require repetitive inspections of specific
MOV actuator part numbers installed at
specific locations. The requirements of
those ADs may be terminated if the
applicable conditions specified in
paragraph (m) of this AD are met. We
have not changed this AD regarding this
issue.
Request To Refer to Latest Service
Information
Southwest Airlines requested that we
refer to the latest revisions of the
airworthiness limitations documents.
We agree with the commenter’s
request and have revised this AD to
refer to the current airworthiness
limitations as the appropriate source of
service information, and have included
earlier revisions of the service
information as credit in this AD. There
are no changes to the required actions
of this AD because the tasks that must
be incorporated into the maintenance or
inspection program are not changed in
Boeing 737–600/700/700C/800/900/

–400ER series airplanes, which adds
instructions that further describe the
conditions for performing electrical
bonding resistance measurements, in
addition to being more descriptive
regarding cap seal application.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule with the changes described
previously and minor editorial changes.
We have determined that these minor
changes:
• Are consistent with the intent that
was proposed in the SNPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the SNPRM.
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this final rule.

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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes and associated appliances to
the Director of the System Oversight
Division.
Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
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

(o) Alternative Methods of Compliance
(AMOCs)
(1) The Manager, Seattle ACO Branch,
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
certification office, send it to the attention of
the person identified in paragraph (p)(1) of
this AD. Information may be emailed to: 9ANM-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
Branch, 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 (o)(4)(i) and (o)(4)(ii) of this AD
apply.
(i) The steps labeled as RC, including
substeps under an RC step and any figures
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
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

SUPPLEMENTARY INFORMATION:
Discussion
SUMMARY:
DATES:
Examining the AD Docket
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Airbus SAS Model A350–
941 airplanes. The NPRM published in
the Federal Register on May 15, 2018
(83 FR 22414). The NPRM was
prompted by an inspection on the
production line that revealed evidence
of paint peeling on the forward and aft
cargo frame forks around the hook bolt
hole. The NPRM proposed to require a
detailed visual inspection for any
deficiency of the frame forks around the
hook bolt hole on certain forward and
aft cargo doors and applicable corrective
actions.
We are issuing this AD to address
paint peeling on the forward and aft
cargo doors that could develop into
galvanic corrosion, which could lead to
cargo door failure and possibly result in
decompression of the airplane and
injury to occupants.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2018–0031,
dated January 31, 2018 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all Airbus SAS Model A350–941
airplanes. The MCAI states:
Following an inspection on the production
line, paint peeling was found on forward and
aft cargo door frame forks around the hook
bolt hole. Subsequent investigations
determined this had been caused by incorrect
masking method during application of
primer, top coat and Tartaric Sulfuric
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
51313
Anodizing (TSA) layer. As the cargo doors
are located in an area with high corrosion
sensitivity, where a surface protection with
primer, top coat and TSA is specified, in case
of paint peeling off, galvanic corrosion could
develop.
This condition, if not detected and
corrected, could lead to cargo door failure,
possibly resulting in decompression of the
aeroplane and injury to occupants.
To address this potential unsafe condition,
Airbus identified the affected parts and
issued the SB [Airbus Service Bulletin (SB)
A350–52–P011, dated May 12, 2017] to
provide inspection instructions.
For the reasons described above, this
[EASA] AD requires a one-time detailed
[visual] inspection (DET) of the affected parts
[for discrepancies] and, depending on
findings, accomplishment of applicable
corrective action(s) [i.e., restoration of the
anti-corrosion protection of frame forks of
affected parts].
You may examine the MCAI in the
AD docket on the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2018–
0410.
Comments
We gave the public the opportunity to
participate in developing this final rule.
We received no comments on the NPRM
or on the determination of the cost to
the public.
Clarification of Definition of
Serviceable Part
We have changed paragraph (g)(2) in
this AD by adding that a serviceable part
is also ‘‘a part identified as an affected
part, and the actions in paragraph (i) of
this AD have been accomplished on that
part.’’ This change has been coordinated
with EASA and Airbus.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting this
final rule 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
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

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 737-600, -700, -700C, -800, -900, and -900ER series airplanes;
Model 757 airplanes; and Model 767 airplanes. The NPRM published in the
Federal Register on March 9, 2017 (82 FR 13073). The NPRM was prompted
by reports of latently failed MOV actuators of the fuel shutoff valves.
The NPRM proposed to require replacing certain MOV actuators of the
fuel shutoff valves for the left and right engines (on all airplanes)
and of the APU fuel shutoff valve (on Model 757 and Model 767
airplanes); and revising the maintenance or inspection program, as
applicable, to incorporate certain AWLs.
We subsequently issued a supplemental NPRM (SNPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all Model 737 airplanes,
excluding Model 737-100, -200, -200C, -300, -400, and -500 series
airplanes; and all Model 757 and 767 airplanes. The SNPRM published in
the Federal Register on April 3, 2018 (83 FR 14207). The SNPRM proposed
to add Model 737-8 airplanes and future Model 737 airplanes to the
applicability.
We are issuing this AD to address a latent failure of the actuator
for the engine or APU fuel shutoff valves, which could result in the
inability to shut off fuel to the engine or the APU, and, in case of
certain engine or APU fires, could result in structural failure.
Comments
We gave the public the opportunity to participate in developing
this final rule. The following presents the comments received on the
SNPRM and the FAA's response to each comment.
Request To Exclude Model 737-8 and Future Model 737
Boeing requested that we revise the proposed AD (in the SNPRM) to
exclude Model 737-8 airplanes and future Model 737 airplanes, because
MOV actuator part number MA30A1017 (Boeing P/N S343T003-76) is the only
certified MOV actuator for use on any future Model 737 airplanes as
documented in the drawings and Illustrated Parts Catalog (IPC). The
commenter stated that using airworthiness limitations to prohibit the
use of parts with AD restrictions on one minor model series (Model 737
next generation (NG) airplanes) from being used on a different minor
model series (Model 737-8 and future Model 737 airplanes) that does not
allow the use of the restricted parts is unnecessary and implies that
certified configurations and ADs can be overridden via an Advisory
Circular (AC) or other means.
We disagree with the commenter's request. The MOV actuator
currently allowed on Model 737-8 and 737-9 airplanes, part number
MA30A1017 (Boeing P/N S343T003-76), is the only part number
certificated on those models, as documented in the manufacturer's
drawings. However, manufacturer's proprietary drawings are not readily
available to all affected operators, and there is no prohibition
against installing MOV actuator part numbers that were determined
unsafe in this AD. We have been informed by operators that the practice
of rotating physically interchangeable parts among airplanes is
widespread, and even a key part of their operations. In the absence of
an AD or AWL that restricts the installation of the affected parts, we
cannot be assured that the unsafe condition will not be introduced to
Model 737-8, 737-9, and future 737 airplanes. In addition, ACs are
advisory in nature and do not include mandatory actions. Therefore, ACs
do not take precedence over ADs. We have not changed this AD regarding
this issue.
Request To Remove Requirement To Revise Maintenance Program
Boeing requested that we remove paragraph (j) of the proposed AD
and revise FAA AC 120-77 or other applicable advisory material to
preclude installation of equipment that both Boeing and the FAA have
determined cause a potential safety issue, against certified
configurations. Boeing suggested that listing parts that are not
approved for use on a given model sets a precedent that can become
unmanageable, and that identifying parts that are acceptable for a
given airplane and installation position is a more explicit and
manageable approach. Boeing added that the use of AWLs to prohibit AD-
driven part installations is unnecessary and implies that certified
configurations and ADs can be overridden via an AC or other means.
We disagree with the commenter's request. The FAA is currently
considering revising AC 120-77 to help prevent the rotation of parts as
a minor alteration. However, ACs are advisory in nature and do not
include mandatory actions. Therefore, ACs cannot prohibit the
installation of unsafe equipment, and they do not take precedence over
ADs. In addition, the practice of rotating parts is widespread, and
revising the AC will not improve the situation in a timely manner.
Certain MOV actuator part numbers have been identified to be unsafe for
installation at certain locations. Since those part numbers continue to
be available and acceptable for installation at certain other
locations, we consider the use of AWLs to prohibit specific parts
installation to be a reasonable way to address the safety concern in a
timely manner. We have not changed this AD regarding this issue.
Request To Clarify Affected Part Numbers
FedEx requested that we revise paragraphs (h)(2) and (h)(3) of the
proposed AD (in the SNPRM) to state that no replacement is necessary if
the MOV actuator part number is one of the following alternative part
numbers: AV-31-1 (Boeing P/N S343T003-111), MA11A1265 (Boeing P/N
S343T003-14), or MA11A1265-1 (Boeing P/N S343T003-41). FedEx stated
that the service information specified in paragraphs (h)(2) and (h)(3)
of the proposed AD (in the SNPRM) explicitly state that those
alternative MOV actuator part numbers are acceptable substitutes for P/
N MA30A1017 (Boeing P/N S343T003-76).
We disagree with the commenter's request. However, we agree to
clarify the requirements of paragraphs (h)(2) and (h)(3) of this AD.
Paragraphs (h)(2) and (h)(3) of this AD require replacement of MOV
actuator P/N MA20A2027 (Boeing P/N S343T003-56) and P/N MA30A1001
(Boeing P/N S343T003-66) with an acceptable MOV actuator part number.
Those paragraphs do not state or imply that MOV actuator P/N AV-31-1
(Boeing P/N S343T003-111), P/N MA11A1265 (Boeing P/N S343T003-14), or
P/N MA11A1265-1 (Boeing P/N S343T003-41) must be replaced. Therefore,
we consider that adding the
[[Page 51306]]
proposed statement is unnecessary. We have not changed this AD
regarding this issue.
Request To Add a Terminating Action Provision
FedEx requested that we revise paragraphs (i)(2) and (i)(3) of the
proposed AD (in the SNPRM) to state that the actuator installation
would terminate the daily functional checks required by AWLs 28-AWL-ENG
and 28-AWL-APU. The commenter added that installation of MOV actuator
part number MA30A1017 (Boeing P/N S343T003-76) or an acceptable
alternative part number should substantially increase the safety value.
We disagree with the commenter's request. We have determined that
accomplishing the applicable maintenance or inspection program
revisions specified in paragraph (j) of this AD are the appropriate
terminating actions. As discussed previously in the preamble of the
SNPRM, we included the conditions (accomplishing the applicable
maintenance or inspection program revisions) that would terminate the
requirements of AD 2015-21-10, Amendment 39-18303 (80 FR 65130, October
26, 2015); AD 2015-19-04, Amendment 39-18267 (80 FR 55505, September
16, 2015); and AD 2015-21-09, Amendment 39-18302 (80 FR 65121, October
26, 2015). Those ADs require incorporation of the AWLs that require
repetitive inspections of specific MOV actuator part numbers installed
at specific locations. The requirements of those ADs may be terminated
if the applicable conditions specified in paragraph (m) of this AD are
met. We have not changed this AD regarding this issue.
Request To Refer to Latest Service Information
Southwest Airlines requested that we refer to the latest revisions
of the airworthiness limitations documents.
We agree with the commenter's request and have revised this AD to
refer to the current airworthiness limitations as the appropriate
source of service information, and have included earlier revisions of
the service information as credit in this AD. There are no changes to
the required actions of this AD because the tasks that must be
incorporated into the maintenance or inspection program are not changed
in Boeing 737-600/700/700C/800/900/900ER Special Compliance Items/
Airworthiness Limitations, D626A001-9-04, Revision June 2018; Boeing
757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness
Limitations (AWLS) and Certification Maintenance Requirements (CMRs),
D622N001-9, Revision May 2018; or Boeing 767-200/300/300F/400 Special
Compliance Items/Airworthiness Limitations, D622T001-9-04, Revision
March 2018; except for Task 28-AWL-23 for Model 767-200, -300, -300F,
and -400ER series airplanes, which adds instructions that further
describe the conditions for performing electrical bonding resistance
measurements, in addition to being more descriptive regarding cap seal
application.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule with the changes described previously and minor
editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
SNPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the SNPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Costs of Compliance
We estimate that this AD affects 2,557 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection and replacement Model Up to 6 work-hours x Up to $12,000................. Up to $12,510................. Up to $18,014,400.
737 (1,440 airplanes). $85 per hour = Up to
$510.
Inspection and replacement Model Up to 9 work-hours x Up to $18,000................. Up to $18,765................. Up to $12,666,375.
757 (675 airplanes). $85 per hour = Up to
$765.
Inspection and replacement Model Up to 9 work-hours x Up to $18,000................. Up to $18,765................. Up to $8,294,130.
767 (442 airplanes). $85 per hour = Up to
$765.
--------------------------------------------------------------------------------------------------------------------------------------------------------
For the maintenance/inspection program revision, we have determined
that this action takes an average of 90 work-hours per operator,
although we recognize that this number may vary from operator to
operator. In the past,
[[Page 51307]]
we have estimated that this action takes 1 work-hour per airplane.
Since operators incorporate maintenance or inspection program changes
for their affected fleets, we have determined that a per-operator
estimate is more accurate than a per-airplane estimate. Therefore, we
estimate the total cost per operator to be $7,650 (90 work-hours x $85
per work-hour).
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
