E. Use of Plain Language
DEPARTMENT OF TRANSPORTATION
Section 722 of the Gramm-LeachBliley Act 25 requires the Federal
banking agencies to use ‘‘plain
language’’ in all proposed and final
rules published after January 1, 2000. In
light of this requirement, the agencies
have sought to present the final rule in
a simple and straightforward manner.
The agencies did not receive any
comments on the use of plain language.
Federal Aviation Administration
F. Unfunded Mandates Act
AGENCY:
As a general matter, the Unfunded
Mandates Act of 1995 (UMRA), 2 U.S.C.
1531 et seq., requires the preparation of
a budgetary impact statement before
promulgating a rule that includes a
Federal mandate that may result in the
expenditure by State, local, and tribal
governments, in the aggregate, or by the
private sector, of $100 million or more
in any one year. However, the UMRA
does not apply to final rules for which
a general notice of proposed rulemaking
was not published.26 Therefore, because
the OCC has found good cause to
dispense with notice and comment for
the final rule, the OCC concludes that
the requirements of UMRA do not apply
to this final rule.
Authority and Issuance
For the reasons set forth in the joint
preamble, the interim final rules which
were published at 85 FR 22924 and 85
FR 22930 on April 23, 2020, are adopted
as a final rule by the OCC, Board, and
FDIC without change.
Brian P. Brooks,
Acting Comptroller of the Currency.
By order of the Board of Governors of the
Federal Reserve System.
Ann Misback,
Secretary of the Board.
Federal Deposit Insurance Corporation.
By order of the Board of Directors.
Dated at Washington, DC, on or about

Administration (FAA), DOT.
ACTION: Final rule.
The FAA is superseding
Airworthiness Directives (ADs) 2015–
14–07, 2016–07–10, and 2016–24–09.
AD 2015–14–07 applied to certain The
Boeing Company Model 787–8
airplanes. AD 2016–07–10 and AD
2016–24–09 applied to all The Boeing
Company Model 787–8 and 787–9
airplanes. ADs 2015–14–07, 2016–07–
10, and 2016–24–09 required actions
related to certain flight control module
(FCM) software. This AD requires
installing flight control electronics
(FCE) common block point 5 (CBP5)
software, which terminates the
requirements of the ADs superseded by
this AD. This AD was prompted by
certain deficiencies in the FCM
software, including a report of an
unannunciated dual symmetric inboard
slat skew. The FAA is issuing this AD
to address the unsafe condition on these
products.
DATES: This AD is effective November
13, 2020.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of November 13, 2020.
The Director of the Federal Register
approved the incorporation by reference
of a certain other publication listed in
this AD as of June 6, 2019 (84 FR 18707,
May 2, 2019).
The Director of the Federal Register
approved the incorporation by reference
of a certain other publication listed in
this AD as of December 2, 2016 (81 FR

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede the following ADs:
• AD 2015–14–07, Amendment 39–
18205 (80 FR 42014, July 16, 2015) (‘‘AD
2015–14–07’’). AD 2015–14–07 applied
to certain Model 787–8 airplanes.
• AD 2016–07–10, Amendment 39–
18455 (81 FR 18741, April 1, 2016)
(‘‘AD 2016–07–10’’). AD 2016–07–10
applied to all Model 787–8 and 787–9
airplanes.
• AD 2016–24–09, Amendment 39–
18726 (81 FR 86912, December 2, 2016)
(‘‘AD 2016–24–09’’). AD 2016–24–09
applied to all Model 787–8 and 787–9
airplanes.
The NPRM published in the Federal
Register on January 2, 2020 (85 FR 23).
The NPRM was prompted by
deficiencies in the FCM software,
including reports that, in certain
weather conditions, erroneous low
airspeed data may be displayed to the
flightcrew before detection and
annunciation via engine-indicating and
crew alerting system (EICAS) messages,
a report indicating that all three FCMs
might simultaneously reset if
continuously powered on for 22 days,
E:\FR\FM\09OCR1.SGM
09OCR1
64010
Federal Register / Vol. 85, No. 197 / Friday, October 9, 2020 / Rules and Regulations
and one report of unannunciated dual
symmetric inboard slat skew. The
NPRM proposed to require installing
FCE CBP5 software, which would also
address the identified unsafe conditions
and terminate the requirements of the
ADs superseded by this AD. The FAA
is issuing this AD to address
deficiencies in the FCM software that
could prevent continued safe flight and
landing; to prevent unrealistic, sudden
drops in displayed airspeed at high
actual airspeed, which could lead to
pilot control inputs that could exceed
the structural capability of the airplane;
to prevent simultaneous resets of all
three FCMs, which could result in flight
control surfaces not moving in response
to flight crew inputs for a short time and
consequent temporary loss of
controllability; and to address potential
unannunciated dual symmetric inboard
slat skew, which can result in adverse
handling characteristics of the aircraft.
Changes Since the NPRM Was Issued
The FAA has reviewed Boeing Alert
Requirements Bulletin B787–81205–
SB270044–00 RB, Issue 002, dated July
7, 2020 (the FAA referred to Boeing
Alert Requirements Bulletin B787–
81205–SB270044–00 RB, Issue 001,
dated December 18, 2018, as an
appropriate source of service
information for accomplishing the
actions specified in the NPRM) and has
revised this AD to refer to Boeing Alert
Requirements Bulletin B787–81205–
SB270044–00 RB, Issue 002, dated July
7, 2020. This service information
removes a certain airplane line number
from the effectivity; otherwise, there is
no substantive change from Issue 001,
dated December 18, 2018. The FAA has
added paragraph (p) to this AD to
provide credit for actions done prior to
the effective date of this AD using
Boeing Alert Requirements Bulletin
B787–81205–SB270044–00 RB, Issue
001, dated December 18, 2018.
Subsequent paragraphs have been
redesignated accordingly.
Explanation of Concurrent
Requirements
This AD requires the accomplishment
of Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 002, dated
March 8, 2018, prior to or concurrently
with the software installation specified
in paragraph (n)(1) of this AD. AD 2019–
08–05, Amendment 39–19626 (84 FR
18707, May 2, 2019) (‘‘AD 2019–08–05’’)
also requires the accomplishment of
Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 002, dated
March 8, 2018, prior to or concurrently
with the installation of hydraulic tubing
and a pressure-operated check valve,
VerDate Sep<11>2014
16:35 Oct 08, 2020
Jkt 253001
which corrects a different unsafe
condition; so the concurrent
requirement is in both ADs. The
compliance time for this AD is shorter
than the compliance time for AD 2019–
08–05.
Explanation of Changes to Paragraphs
(n) and (o) of This AD
The FAA revised paragraph (n)(3) of
this AD and removed paragraph (n)(4) of
this AD. This revision clarifies the
compliance time for installation of a
new displays and crew alerting (DCA)
system and maintenance system (MS)
software, clarifies ‘‘later-approved
version’’ in regard to DCA MS software,
and clarifies that this action applies
only to certain airplanes. The FAA also
revised the introductory text to
paragraph (n) of this AD to clarify the
applicable actions.
The FAA also revised paragraphs
(o)(1) and (2) of this AD which clarify
‘‘later-approved version’’ in regard to
CBP5 and DCA MS CBP4 software.
Explanation of Changes to Paragraph
(q)(3) of This AD
The FAA revised paragraph (q)(3) of
this AD to clarify the terminating action.
The intent of paragraph (q)(3) of this AD
is to require the removal of figure 1 to
paragraph (k) of this AD after the actions
required by paragraph (n) or (o) of this
AD have been accomplished on all
affected airplanes in an operator’s fleet.
Accomplishment of these actions then
terminates paragraph (k) of this AD for
all affected airplanes in an operator’s
fleet.
Comments
The FAA 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
The Air Line Pilots Association,
International (ALPA) stated its support
for the NPRM. United Airlines indicated
no objection to the NPRM.
Request To Clarify What Prompted the
Unsafe Condition
Boeing asked that a clarification of the
number of occurrences of
unannunciated dual symmetric inboard
slat skew events be added to the
relevant sections in the proposed AD.
Boeing stated that there has only been
a single unannunciated dual symmetric
inboard slat skew event.
The FAA agrees with the commenter’s
request for clarification, because there
has only been one occurrence of an
unannunciated dual symmetric inboard
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
slat skew. The FAA has revised the
Discussion section, and
paragraph (e) of this AD accordingly.
However, the section titled ‘‘Actions
Since ADs 2015–14–07, 2016–07–10,
and 2016–24–09 Were Issued,’’ which
was included in the proposed AD, is not
carried over in this final rule.
Boeing also asked that the FAA
differentiate the number of occurrences
of unannunciated dual symmetric
inboard slat skew from the outboard slat
skew issue, which is the subject of AD
2019–20–07. Boeing noted that the
potential for unannunciated dual
symmetric inboard slat skew, addressed
by this AD, is not related to the
outboard slat skew issue that is the
subject of that AD.
Although the FAA agrees that the
issues are not related, that clarification
is not required in the content of this AD.
Therefore, the FAA has not changed this
AD in this regard.
SUMMARY,
Request To Allow Installation of LaterApproved Software Versions
Boeing asked that the FAA allow
installation of later-approved FCE
software in lieu of the ‘‘FCM CBP5’’
software identified in Boeing Alert
Requirements Bulletin B787–81205–
SB270044–00 RB, Issue 001, dated
December 18, 2018. Boeing stated that
the use of ‘‘later-approved software’’
language was used in AD 2019–08–05,
Amendment 39–19626 (84 FR 18707,
May 2, 2019) (‘‘AD 2019–08–05’’)
(referenced in the proposed AD), and
will reduce the need for alternative
method of compliance (AMOC) requests
for future FCM software updates.
The FAA disagrees with the
commenter’s request because the
Actions Required for Compliance
section in Boeing Alert Requirements
Bulletin B787–81205–SB270044–00 RB,
Issue 001, dated December 18, 2018,
already includes an allowance for
installation of a later-approved software
part number. Boeing Alert Requirements
Bulletin B787–81205–SB270044–00 RB,
Issue 002, dated July 7, 2020, also
includes that allowance. Therefore, the
FAA has not changed this AD in this
regard.
Request To Identify Certain Required
for Compliance (‘RC’) Actions
Boeing asked that the FAA revise
paragraph (n)(2) of the proposed AD to
specify accomplishment of only the
concurrent or prior actions identified as
RC in the service bulletin. Boeing stated
that installation of the ‘‘CMCF LDI DB’’
[central maintenance computer function
(CMCF) loadable diagnostic information
(LDI) database (DB)] software is not
required to correct the unsafe condition.
E:\FR\FM\09OCR1.SGM
09OCR1
Federal Register / Vol. 85, No. 197 / Friday, October 9, 2020 / Rules and Regulations
Boeing added that AD 2019–08–05
specifies the applicable service bulletin
actions identified as RC.
The FAA agrees with the commenter’s
request, because installation of the
CMCF LDI DB software is not required
to correct the unsafe condition. If that
software were cited in the requirements
of this AD, any update to this software
would require approval of an AMOC.
The FAA has changed paragraph (n)(2)
of this AD to specify doing only the
applicable actions (including software
installation) that are identified as RC.
Request To Clarify Intent of AD
Boeing asked that the FAA change
paragraph (e) of the proposed AD to
clarify that the AD is also prompted by
the need to provide terminating action
for the three ADs that are superseded by
this AD. Boeing stated that this change
clarifies the intent of the AD.
The FAA agrees with the commenter’s
request to change the text in paragraph
(e) of this AD. The FAA agrees that this
AD is terminating action for the interim
actions identified in two of the
superseded ADs: 2016–07–10 and 2016–
24–09. The superseding of those prior
ADs implies that this AD mitigates the
unsafe condition of those prior ADs.
This AD was prompted by reports of an
identified unsafe condition that this AD
is intended to correct. The FAA has
revised the SUMMARY, Discussion
section, and paragraph (e) of this AD to
include the unsafe conditions that
prompted the superseded ADs, since
this AD also addresses those unsafe
conditions.
Request To Include Credit for
Previously Accomplished Actions
American Airlines (AA) asked for the
addition of credit for previous software
installations done using the following
service information.
• Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 001, dated
July 31, 2017.
• Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 001, dated
July 31, 2017, in conjunction with
Boeing Information Notice B787–A–27–
00–0039–01A–931E–D, Issue 001, dated
September 7, 2017.
AA stated that equivalent credit was
granted in paragraphs (i)(3) and (4) of
AD 2019–08–05 (which the FAA notes
also requires the concurrent installation
of certain software in accordance with
Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 002, dated
March 8, 2018), although AD 2019–08–
05 is unrelated to the NPRM.
The FAA does not agree with the
commenter’s request. The latest version
of the CMCF software specified in
Boeing Alert Service Bulletin B787–
81205–SB270039–00, Issue 002, dated
March 8, 2018, must be installed
concurrently with the FCE CBP5
software in order for the maintenance
system to work properly. Therefore, the
FAA has not changed this AD in this
regard.
Conclusion
The FAA 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. The FAA
has 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.
The FAA 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
The FAA reviewed Boeing Alert
Requirements Bulletin B787–81205–
SB270044–00 RB, Issue 002, dated July

This AD also requires Boeing Alert
Service Bulletin B787–81205–
SB270039–00, Issue 002, dated March 8,
2018, which the Director of the Federal
Register approved for incorporation by
reference as of June 6, 2019 (84 FR
18707, May 2, 2019).
This AD also requires Boeing Alert
Service Bulletin B787–81205–
SB270040–00, Issue 001, dated
November 25, 2016, which the Director
of the Federal Register approved for
incorporation by reference as of

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
The FAA estimates that this AD
affects 78 airplanes of U.S. registry.
The compliance time has passed for
the retained requirements in this AD, so
all affected airplanes should already be
in compliance with those requirements.
Therefore, this AD imposes no
additional financial burden on any U.S.
operator.
However, if a noncompliant airplane
is imported and placed on the U.S.
Register in the future, the FAA estimates
the following costs to comply with the
retained actions:

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.
The FAA is 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
The FAA has determined that 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) Will not affect intrastate aviation
in Alaska, and
(3) 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.

the FCM software, including reports that, in
certain weather conditions, erroneous low
airspeed data may be displayed to the
flightcrew before detection and annunciation
via engine-indicating and crew alerting
system (EICAS) messages, a report indicating
that all three FCMs might simultaneously
reset if continuously powered on for 22 days,
and one report of unannunciated dual
symmetric inboard slat skew. The FAA is
issuing this AD to address deficiencies in the
FCM software that could prevent continued

safe flight and landing; to prevent unrealistic,
sudden drops in displayed airspeed at high
actual airspeed, which could lead to pilot
control inputs that could exceed the
structural capability of the airplane; to
prevent simultaneous resets of all three
FCMs, which could result in flight control
surfaces not moving in response to flight
crew inputs for a short time and consequent
temporary loss of controllability; and to
address potential unannunciated dual
symmetric inboard slat skew, which can
result in adverse handling characteristics of
the aircraft.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede the following ADs:
AD 2015-14-07, Amendment 39-18205 (80 FR 42014, July 16,
2015) (``AD 2015-14-07''). AD 2015-14-07 applied to certain Model 787-8
airplanes.
AD 2016-07-10, Amendment 39-18455 (81 FR 18741, April 1,
2016) (``AD 2016-07-10''). AD 2016-07-10 applied to all Model 787-8 and
787-9 airplanes.
AD 2016-24-09, Amendment 39-18726 (81 FR 86912, December
2, 2016) (``AD 2016-24-09''). AD 2016-24-09 applied to all Model 787-8
and 787-9 airplanes.
The NPRM published in the Federal Register on January 2, 2020 (85
FR 23). The NPRM was prompted by deficiencies in the FCM software,
including reports that, in certain weather conditions, erroneous low
airspeed data may be displayed to the flightcrew before detection and
annunciation via engine-indicating and crew alerting system (EICAS)
messages, a report indicating that all three FCMs might simultaneously
reset if continuously powered on for 22 days,
[[Page 64010]]
and one report of unannunciated dual symmetric inboard slat skew. The
NPRM proposed to require installing FCE CBP5 software, which would also
address the identified unsafe conditions and terminate the requirements
of the ADs superseded by this AD. The FAA is issuing this AD to address
deficiencies in the FCM software that could prevent continued safe
flight and landing; to prevent unrealistic, sudden drops in displayed
airspeed at high actual airspeed, which could lead to pilot control
inputs that could exceed the structural capability of the airplane; to
prevent simultaneous resets of all three FCMs, which could result in
flight control surfaces not moving in response to flight crew inputs
for a short time and consequent temporary loss of controllability; and
to address potential unannunciated dual symmetric inboard slat skew,
which can result in adverse handling characteristics of the aircraft.
Changes Since the NPRM Was Issued
The FAA has reviewed Boeing Alert Requirements Bulletin B787-81205-
SB270044-00 RB, Issue 002, dated July 7, 2020 (the FAA referred to
Boeing Alert Requirements Bulletin B787-81205-SB270044-00 RB, Issue
001, dated December 18, 2018, as an appropriate source of service
information for accomplishing the actions specified in the NPRM) and
has revised this AD to refer to Boeing Alert Requirements Bulletin
B787-81205-SB270044-00 RB, Issue 002, dated July 7, 2020. This service
information removes a certain airplane line number from the
effectivity; otherwise, there is no substantive change from Issue 001,
dated December 18, 2018. The FAA has added paragraph (p) to this AD to
provide credit for actions done prior to the effective date of this AD
using Boeing Alert Requirements Bulletin B787-81205-SB270044-00 RB,
Issue 001, dated December 18, 2018. Subsequent paragraphs have been
redesignated accordingly.
Explanation of Concurrent Requirements
This AD requires the accomplishment of Boeing Alert Service
Bulletin B787-81205-SB270039-00, Issue 002, dated March 8, 2018, prior
to or concurrently with the software installation specified in
paragraph (n)(1) of this AD. AD 2019-08-05, Amendment 39-19626 (84 FR
18707, May 2, 2019) (``AD 2019-08-05'') also requires the
accomplishment of Boeing Alert Service Bulletin B787-81205-SB270039-00,
Issue 002, dated March 8, 2018, prior to or concurrently with the
installation of hydraulic tubing and a pressure-operated check valve,
which corrects a different unsafe condition; so the concurrent
requirement is in both ADs. The compliance time for this AD is shorter
than the compliance time for AD 2019-08-05.
Explanation of Changes to Paragraphs (n) and (o) of This AD
The FAA revised paragraph (n)(3) of this AD and removed paragraph
(n)(4) of this AD. This revision clarifies the compliance time for
installation of a new displays and crew alerting (DCA) system and
maintenance system (MS) software, clarifies ``later-approved version''
in regard to DCA MS software, and clarifies that this action applies
only to certain airplanes. The FAA also revised the introductory text
to paragraph (n) of this AD to clarify the applicable actions.
The FAA also revised paragraphs (o)(1) and (2) of this AD which
clarify ``later-approved version'' in regard to CBP5 and DCA MS CBP4
software.
Explanation of Changes to Paragraph (q)(3) of This AD
The FAA revised paragraph (q)(3) of this AD to clarify the
terminating action. The intent of paragraph (q)(3) of this AD is to
require the removal of figure 1 to paragraph (k) of this AD after the
actions required by paragraph (n) or (o) of this AD have been
accomplished on all affected airplanes in an operator's fleet.
Accomplishment of these actions then terminates paragraph (k) of this
AD for all affected airplanes in an operator's fleet.
Comments
The FAA 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
The Air Line Pilots Association, International (ALPA) stated its
support for the NPRM. United Airlines indicated no objection to the
NPRM.
Request To Clarify What Prompted the Unsafe Condition
Boeing asked that a clarification of the number of occurrences of
unannunciated dual symmetric inboard slat skew events be added to the
relevant sections in the proposed AD. Boeing stated that there has only
been a single unannunciated dual symmetric inboard slat skew event.
The FAA agrees with the commenter's request for clarification,
because there has only been one occurrence of an unannunciated dual
symmetric inboard slat skew. The FAA has revised the SUMMARY,
Discussion section, and paragraph (e) of this AD accordingly. However,
the section titled ``Actions Since ADs 2015-14-07, 2016-07-10, and
2016-24-09 Were Issued,'' which was included in the proposed AD, is not
carried over in this final rule.
Boeing also asked that the FAA differentiate the number of
occurrences of unannunciated dual symmetric inboard slat skew from the
outboard slat skew issue, which is the subject of AD 2019-20-07. Boeing
noted that the potential for unannunciated dual symmetric inboard slat
skew, addressed by this AD, is not related to the outboard slat skew
issue that is the subject of that AD.
Although the FAA agrees that the issues are not related, that
clarification is not required in the content of this AD. Therefore, the
FAA has not changed this AD in this regard.
Request To Allow Installation of Later-Approved Software Versions
Boeing asked that the FAA allow installation of later-approved FCE
software in lieu of the ``FCM CBP5'' software identified in Boeing
Alert Requirements Bulletin B787-81205-SB270044-00 RB, Issue 001, dated
December 18, 2018. Boeing stated that the use of ``later-approved
software'' language was used in AD 2019-08-05, Amendment 39-19626 (84
FR 18707, May 2, 2019) (``AD 2019-08-05'') (referenced in the proposed
AD), and will reduce the need for alternative method of compliance
(AMOC) requests for future FCM software updates.
The FAA disagrees with the commenter's request because the Actions
Required for Compliance section in Boeing Alert Requirements Bulletin
B787-81205-SB270044-00 RB, Issue 001, dated December 18, 2018, already
includes an allowance for installation of a later-approved software
part number. Boeing Alert Requirements Bulletin B787-81205-SB270044-00
RB, Issue 002, dated July 7, 2020, also includes that allowance.
Therefore, the FAA has not changed this AD in this regard.
Request To Identify Certain Required for Compliance (`RC') Actions
Boeing asked that the FAA revise paragraph (n)(2) of the proposed
AD to specify accomplishment of only the concurrent or prior actions
identified as RC in the service bulletin. Boeing stated that
installation of the ``CMCF LDI DB'' [central maintenance computer
function (CMCF) loadable diagnostic information (LDI) database (DB)]
software is not required to correct the unsafe condition.
[[Page 64011]]
Boeing added that AD 2019-08-05 specifies the applicable service
bulletin actions identified as RC.
The FAA agrees with the commenter's request, because installation
of the CMCF LDI DB software is not required to correct the unsafe
condition. If that software were cited in the requirements of this AD,
any update to this software would require approval of an AMOC. The FAA
has changed paragraph (n)(2) of this AD to specify doing only the
applicable actions (including software installation) that are
identified as RC.
Request To Clarify Intent of AD
Boeing asked that the FAA change paragraph (e) of the proposed AD
to clarify that the AD is also prompted by the need to provide
terminating action for the three ADs that are superseded by this AD.
Boeing stated that this change clarifies the intent of the AD.
The FAA agrees with the commenter's request to change the text in
paragraph (e) of this AD. The FAA agrees that this AD is terminating
action for the interim actions identified in two of the superseded ADs:
2016-07-10 and 2016-24-09. The superseding of those prior ADs implies
that this AD mitigates the unsafe condition of those prior ADs. This AD
was prompted by reports of an identified unsafe condition that this AD
is intended to correct. The FAA has revised the SUMMARY, Discussion
section, and paragraph (e) of this AD to include the unsafe conditions
that prompted the superseded ADs, since this AD also addresses those
unsafe conditions.
Request To Include Credit for Previously Accomplished Actions
American Airlines (AA) asked for the addition of credit for
previous software installations done using the following service
information.
Boeing Alert Service Bulletin B787-81205-SB270039-00,
Issue 001, dated July 31, 2017.
Boeing Alert Service Bulletin B787-81205-SB270039-00,
Issue 001, dated July 31, 2017, in conjunction with Boeing Information
Notice B787-A-27-00-0039-01A-931E-D, Issue 001, dated September 7,
2017.
AA stated that equivalent credit was granted in paragraphs (i)(3)
and (4) of AD 2019-08-05 (which the FAA notes also requires the
concurrent installation of certain software in accordance with Boeing
Alert Service Bulletin B787-81205-SB270039-00, Issue 002, dated March
8, 2018), although AD 2019-08-05 is unrelated to the NPRM.
The FAA does not agree with the commenter's request. The latest
version of the CMCF software specified in Boeing Alert Service Bulletin
B787-81205-SB270039-00, Issue 002, dated March 8, 2018, must be
installed concurrently with the FCE CBP5 software in order for the
maintenance system to work properly. Therefore, the FAA has not changed
this AD in this regard.
Conclusion
The FAA 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. The FAA has 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.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.

Costs of Compliance
The FAA estimates that this AD affects 78 airplanes of U.S.
registry.
The compliance time has passed for the retained requirements in
this AD, so all affected airplanes should already be in compliance with
those requirements. Therefore, this AD imposes no additional financial
burden on any U.S. operator.
However, if a noncompliant airplane is imported and placed on the
U.S. Register in the future, the FAA estimates the following costs to
comply with the retained actions:
Estimated Costs for Retained Requirements
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Retained requirements of AD 2015-14[dash]07 4 work-hours x $85 per hour = $0 $340
(11 airplanes). $340.
Retained requirements of AD 2016-07-10........ 1 work-hour x $85 per hour = $85 0 85
Retained requirements of AD 2016-24-09........ 1 work-hour x $85 per hour = $85 0 85

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.
The FAA is 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
The FAA has determined that 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) Will not affect intrastate aviation in Alaska, and
(3) 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.

(a) Effective Date
This AD is effective November 13, 2020.
(b) Affected ADs
This AD replaces the ADs identified in paragraphs (b)(1) through
(3) of this AD.
(1) AD 2015-14-07, Amendment 39-18205 (80 FR 42014, July 16,
2015) (``AD 2015-14-07'').
(2) AD 2016-07-10, Amendment 39-18455 (81 FR 18741, April 1,
2016) (``AD 2016-07-10'').
(3) AD 2016-24-09, Amendment 39-18726 (81 FR 86912, December 2,

(c) Applicability
This AD applies to all The Boeing Company Model 787-8 and 787-9
airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 27, Flight
Controls.
(e) Unsafe Condition
This AD was prompted by deficiencies in the FCM software,
including reports that, in certain weather conditions, erroneous low
airspeed data may be displayed to the flightcrew before detection
and annunciation via engine-indicating and crew alerting system
(EICAS) messages, a report indicating that all three FCMs might
simultaneously reset if continuously powered on for 22 days, and one
report of unannunciated dual symmetric inboard slat skew. The FAA is
issuing this AD to address deficiencies in the FCM software that
could prevent continued safe flight and landing; to prevent
unrealistic, sudden drops in displayed airspeed at high actual
airspeed, which could lead to pilot control inputs that could exceed
the structural capability of the airplane; to prevent simultaneous
resets of all three FCMs, which could result in flight control
surfaces not moving in response to flight crew inputs for a short
time and consequent temporary loss of controllability; and to
address potential unannunciated dual symmetric inboard slat skew,
which can result in adverse handling characteristics of the
aircraft.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
