Federal Register / Vol. 85, No. 198 / Tuesday, October 13, 2020 / Proposed Rules
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 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) 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.
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
1. The authority citation for part 39

Federal Register / Vol. 85, No. 198 / Tuesday, October 13, 2020 / Proposed Rules
The FAA proposes to
supersede Airworthiness Directive (AD)
2017–26–10 which applies to certain
The Boeing Company Model 757
airplanes. AD 2017–26–10 requires
deactivating the spoiler control module
relays and capping and stowing the
associated wiring on certain airplanes.
Since the FAA issued AD 2017–26–10,
Boeing has developed wiring changes
for certain spoiler control modules
(SCMs), which will improve the lateral
handling qualities of the airplane during
approach and landing. This proposed
AD would require repetitive operational
tests of the spoiler inhibit function. For
certain airplanes, this proposed AD
would require installing a new relay
bracket assembly, making changes to the
wire bundles for certain SCMs,
installing new SCMs, measuring the
clearance between a wire bundle and
the top of the new relay bracket
assembly, and applicable on-condition
actions. For a certain other airplane, this
proposed AD would require changing
certain wire bundles. The FAA is
proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments
on this proposed AD by November 27,
2020.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
The FAA issued AD 2017–26–10,
Amendment 39–19141 (82 FR 61675,
December 29, 2017) (‘‘AD 2017–26–
10’’), for certain The Boeing Company
Model 757 airplanes. AD 2017–26–10
requires deactivating the spoiler control
module relays and capping and stowing
the associated wiring on certain
airplanes. AD 2017–26–10 resulted from
a report of an uncommanded spoiler
movement during flap configuration just
before landing. The FAA issued AD
2017–26–10 to address a failure
condition that can cause an
uncommanded spoiler movement
resulting in loss of controllability of the
airplane during the approach phase of
flight.
Confidential Business Information
CBI is commercial or financial
information that is both customarily and
actually treated as private by its owner.
Under the Freedom of Information Act
(FOIA) (5 U.S.C. 552), CBI is exempt
from public disclosure. If your
comments responsive to this NPRM

Actions Since AD 2017–26–10 Was
Issued
Since the FAA issued AD 2017–26–
10, Boeing has developed wiring
changes for SCMs M530 and M531.
These wiring changes will prevent
control wheel inputs to spoiler pairs 1
and 12 and 5 and 8 when the flaps are
extended to a landing configuration
position (flaps in the detent 25 or detent
30 position). The FAA has determined
that this change will improve the lateral
handling qualities of the airplane during
approach and landing and it is
considered the final action to address
the identified unsafe condition.
Related IBR Under 1 CFR Part 51
The FAA reviewed Boeing Alert
Requirements Bulletin 757–27A0158
RB, dated July 9, 2020. The service
information describes procedures for
installing a new relay bracket assembly,
E:\FR\FM\13OCP1.SGM
13OCP1
64421
Federal Register / Vol. 85, No. 198 / Tuesday, October 13, 2020 / Proposed Rules
making changes to the wire bundles for
the SCMs, installing new SCMs,
measuring the clearance between a wire
bundle and the top of new relay bracket
assembly, changing certain wire
bundles, repetitive operational tests of
the spoiler inhibit function, and
applicable on-condition actions. Oncondition actions include installing a
new protective sleeve, heat shrinkable
to the wire bundle, doing a landing
configurations warning module landing
flap tests, and doing a system test for the
SCMs. 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.
Minimum Equipment List (MEL)
Provision
The FAA allows operators to utilize a
MEL for time-limited operation with
certain equipment inoperative, after
which the system must be fully restored.
(See 14 CFR 91.213, 121.628, 125.201,
and 129.14.) This proposed AD would
continue to allow use of an existing
FAA-approved MEL even if the spoiler
inhibit function (SIF) system is
inoperable, so long as the operator’s
existing FAA-approved MEL has a
provision to allow for this inoperability.
FAA’s Determination
The FAA is proposing this AD
because the agency 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 retain none
of the requirements of AD 2017–26–10.
This proposed AD would also require
accomplishment of the actions
identified in Boeing Alert Requirements
Bulletin 757–27A0158 RB, dated July 9,
2020, described previously, except for
any differences identified as exceptions
in the regulatory text of this proposed
AD.
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–2020–
0903.
Explanation of Requirements Bulletin
The FAA worked in conjunction with
industry, under the Airworthiness
Directive Implementation Aviation
Rulemaking Committee (AD ARC), to
enhance the AD system. One
enhancement is a process for annotating
which steps in the service information
are ‘‘required for compliance’’ (RC) with
an AD. Boeing has implemented this RC
concept into Boeing service bulletins.
In an effort to further improve the
quality of ADs and AD-related Boeing
service information, a joint process
improvement initiative was worked
between the FAA and Boeing. The
initiative resulted in the development of
a new process in which the service
information more clearly identifies the
actions needed to address the unsafe
condition in the ‘‘Accomplishment
Instructions.’’ The new process results
in a Boeing Requirements Bulletin,
which contains only the actions needed
to address the unsafe condition (i.e.,
only the RC actions).
Costs of Compliance
The FAA estimates that this proposed
AD affects 626 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
[[Page 64420]]
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2017-26-10 which applies to certain The Boeing Company Model 757
airplanes. AD 2017-26-10 requires deactivating the spoiler control
module relays and capping and stowing the associated wiring on certain
airplanes. Since the FAA issued AD 2017-26-10, Boeing has developed
wiring changes for certain spoiler control modules (SCMs), which will
improve the lateral handling qualities of the airplane during approach
and landing. This proposed AD would require repetitive operational
tests of the spoiler inhibit function. For certain airplanes, this
proposed AD would require installing a new relay bracket assembly,
making changes to the wire bundles for certain SCMs, installing new
SCMs, measuring the clearance between a wire bundle and the top of the
new relay bracket assembly, and applicable on-condition actions. For a
certain other airplane, this proposed AD would require changing certain
wire bundles. The FAA is proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments on this proposed AD by November
27, 2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

docket for this rulemaking.
Discussion
The FAA issued AD 2017-26-10, Amendment 39-19141 (82 FR 61675,
December 29, 2017) (``AD 2017-26-10''), for certain The Boeing Company
Model 757 airplanes. AD 2017-26-10 requires deactivating the spoiler
control module relays and capping and stowing the associated wiring on
certain airplanes. AD 2017-26-10 resulted from a report of an
uncommanded spoiler movement during flap configuration just before
landing. The FAA issued AD 2017-26-10 to address a failure condition
that can cause an uncommanded spoiler movement resulting in loss of
controllability of the airplane during the approach phase of flight.
Actions Since AD 2017-26-10 Was Issued
Since the FAA issued AD 2017-26-10, Boeing has developed wiring
changes for SCMs M530 and M531. These wiring changes will prevent
control wheel inputs to spoiler pairs 1 and 12 and 5 and 8 when the
flaps are extended to a landing configuration position (flaps in the
detent 25 or detent 30 position). The FAA has determined that this
change will improve the lateral handling qualities of the airplane
during approach and landing and it is considered the final action to
address the identified unsafe condition.
Related IBR Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin 757-27A0158 RB,
dated July 9, 2020. The service information describes procedures for
installing a new relay bracket assembly,
[[Page 64421]]
making changes to the wire bundles for the SCMs, installing new SCMs,
measuring the clearance between a wire bundle and the top of new relay
bracket assembly, changing certain wire bundles, repetitive operational
tests of the spoiler inhibit function, and applicable on-condition
actions. On-condition actions include installing a new protective
sleeve, heat shrinkable to the wire bundle, doing a landing
configurations warning module landing flap tests, and doing a system
test for the SCMs. 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.
Minimum Equipment List (MEL) Provision
The FAA allows operators to utilize a MEL for time-limited
operation with certain equipment inoperative, after which the system
must be fully restored. (See 14 CFR 91.213, 121.628, 125.201, and
129.14.) This proposed AD would continue to allow use of an existing
FAA-approved MEL even if the spoiler inhibit function (SIF) system is
inoperable, so long as the operator's existing FAA-approved MEL has a
provision to allow for this inoperability.
FAA's Determination
The FAA is proposing this AD because the agency 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 retain none of the requirements of AD 2017-
26-10. This proposed AD would also require accomplishment of the
actions identified in Boeing Alert Requirements Bulletin 757-27A0158
RB, dated July 9, 2020, described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD.
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-2020-0903.
Explanation of Requirements Bulletin
The FAA worked in conjunction with industry, under the
Airworthiness Directive Implementation Aviation Rulemaking Committee
(AD ARC), to enhance the AD system. One enhancement is a process for
annotating which steps in the service information are ``required for
compliance'' (RC) with an AD. Boeing has implemented this RC concept
into Boeing service bulletins.
In an effort to further improve the quality of ADs and AD-related
Boeing service information, a joint process improvement initiative was
worked between the FAA and Boeing. The initiative resulted in the
development of a new process in which the service information more
clearly identifies the actions needed to address the unsafe condition
in the ``Accomplishment Instructions.'' The new process results in a
Boeing Requirements Bulletin, which contains only the actions needed to
address the unsafe condition (i.e., only the RC actions).
Costs of Compliance
The FAA estimates that this proposed AD affects 626 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------

per test cycle.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required. The FAA has no way of
determining the number of aircraft that might need these on-condition
actions:

----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on the parts cost for the on-condition installation specified in 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, 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 proposed AD would not have
federalism
[[Page 64422]]
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 that the proposed
regulation:
(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.
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:

(e) Unsafe Condition
This AD was prompted by reports of unwanted lateral oscillations
during landing operations, and the development of wiring changes for
certain spoiler control modules (SCMs), which will improve the
lateral handling qualities of the airplane during approach and
landing. The FAA is issuing this AD to address unwanted lateral
oscillations during landing operations, which could cause over-
control of the airplane and subsequent lateral pilot induced
oscillation, which could affect continued safe flight and landing.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Except as specified by paragraph (h) of this AD: At the
applicable times specified in the ``Compliance'' paragraph of Boeing
Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, do
all applicable actions identified in, and in accordance with, the
Accomplishment Instructions of Boeing Alert Requirements Bulletin
757-27A0158 RB, dated July 9, 2020.
Note 1 to paragraph (g): Guidance for accomplishing the actions
required by this AD can be found in Boeing Alert Service Bulletin
757-27A0158, dated July 9, 2020, which is referred to in Boeing
