contact received about this proposed
AD.
Discussion
The FAA has received reports of
partial and full inboard foreflap
departures from the airplane, some of
which resulted in significant damage to
the airplane. Inboard foreflap departures
have been attributed to inadequate
lubrication of the outboard fitting
assembly, corrosion of the outboard
fitting assembly, and corrosion in the
inboard link assembly. In addition,
broken center toggle rollers at the
inboard sequence carriage and binding
of inboard foreflap tracks due to
defective or seized foreflap track rollers
can lead to higher than normal loads on
the outboard fitting assembly and the
inboard link assembly, which may lead
to cracked or broken attachment fittings,
and in some cases the damage has
resulted in an inboard foreflap departing
the airplane. This condition, if not
addressed, could result in the departure
of an inboard foreflap assembly from the
airplane possibly resulting in damage to
the airplane, and adversely affecting the
airplane’s continued safe flight and
landing.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Alert
Requirements Bulletin 747–57A2367
RB, dated November 15, 2019. This
service information describes
procedures for repetitive replacement of
certain parts; a general visual inspection
to determine production configuration
for certain parts; a repetitive lubrication
of certain parts and a repetitive general
visual inspection of certain parts for any
exuding grease; repetitive detailed
inspections of certain parts for loose or
missing attachment bolts, cracks or
bushing migration, cracks or gouges, or
broken, binding, or missing rollers;
repetitive detailed inspections of certain
parts for cracks or corrosion; repetitive
lubrication; and on-condition actions if
necessary. On-condition actions include
replacements and repair.
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
The FAA is proposing this AD
because the FAA 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
accomplishment of the actions
identified in Boeing Alert Requirements
Bulletin 747–57A2367 RB, dated
November 15, 2019, 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–
0211.
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 125 airplanes of U.S. registry.
The FAA estimate the following costs to
comply with this proposed AD:

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
The FAA has received no definitive
data that would enable the FAA to
provide cost estimates for the oncondition repairs 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.
jbell on DSKJLSW7X2PROD with PROPOSALS
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.

Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for all
General Electric Company (GE) GE90–
110B1 and GE90–115B model turbofan
engines with a certain high-pressure
turbine (HPT) rotor stage 2 disk
installed. This proposed AD was
prompted by a report from the
manufacturer that a subsurface anomaly
was found on a HPT rotor stage 2 disk.
This proposed AD would require an
ultrasonic inspection (USI) of the HPT
rotor stage 2 disk and, depending on the
result of the inspection, replacement of
the HPT rotor stage 2 disk with a part
eligible for installation. 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 July 2, 2020.

SUPPLEMENTARY INFORMATION:
Comments Invited
The FAA invites you to send any
written relevant data, views, or
arguments about this proposal. Send
your comments to an address listed
under the ADDRESSES section. Include
‘‘Docket No. FAA–2020–0494; Project
Identifier AD–2020–00324–E’’ at the
beginning of your comments. The FAA
specifically invites comments on the
overall regulatory, economic,
environmental, and energy aspects of
this NPRM. The FAA will consider all
comments received by the closing date
and may amend this NPRM because of
those comments.
Except for Confidential Business
Information (CBI) as described in the
following paragraph, and other
information as described in 14 CFR
11.35, the FAA will post all comments
received, without change, to https://
www.regulations.gov, including any
personal information you provide. The
FAA will also post a report
summarizing each substantive verbal
contact received about this NPRM.
Confidential Business Information
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
PO 00000
Frm 00004
Fmt 4702
Sfmt 4702
(FOIA) (5 U.S.C. 552), CBI is exempt
from public disclosure. If your
comments responsive to this AD contain
commercial or financial information
that is customarily treated as private,
that you actually treat as private, and
that is relevant or responsive to this AD,
it is important that you clearly designate
the submitted comments as CBI. Please
mark each page of your submission
containing CBI as ‘‘PROPIN.’’ The FAA
will treat such marked submissions as
confidential under the FOIA, and they
will not be placed in the public docket
of this AD. Submissions containing CBI
should be sent to Stephen Elwin,
Aerospace Engineer, ECO Branch, FAA,
1200 District Avenue, Burlington, MA,
01803. Any commentary that the FAA
receives which is not specifically
designated as CBI will be placed in the
public docket for this rulemaking.
Discussion
The FAA received a report from the
manufacturer that a subsurface anomaly
was found on a HPT rotor stage 2 disk.
The manufacturer determined that the
subsurface anomaly developed during
the material melting process. This
condition, if not addressed, could result
in uncontained HPT rotor stage 2 disk
release, damage to the engine, and
damage to the airplane.
Related Service Information Under 1
CFR Part 51
The FAA reviewed GE GE90–100
Service Bulletin (SB) 72–0838, dated
January 31, 2020. The SB describes
procedures for performing an USI of the
HPT rotor stage 2 disk. 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
The FAA is proposing this AD
because it 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 an
USI of the HPT rotor stage 2 disk and,
depending on the results of the
inspection, replacement of the HPT
rotor stage 2 disk with a part eligible for
installation.
Costs of Compliance
The FAA estimates that this proposed
AD affects 12 engines installed on
airplanes of U.S. registry.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD,
747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, and
747SR series airplanes. This proposed AD was prompted by reports of
inboard foreflap departures from the airplane. This proposed AD would
require repetitive replacement of certain parts; a general visual
inspection to determine production configuration for certain parts; a
repetitive lubrication of certain parts and a repetitive general visual
inspection of certain parts for any exuding grease; repetitive detailed
inspections of certain parts for loose or missing attachment bolts,
cracks or bushing migration, cracks or gouges, or broken, binding, or
missing rollers; repetitive detailed inspections of certain parts for
cracks or corrosion; repetitive lubrication; and on-condition actions
if necessary. The FAA is proposing this AD to address the unsafe
condition on these products.

Discussion
The FAA has received reports of partial and full inboard foreflap
departures from the airplane, some of which resulted in significant
damage to the airplane. Inboard foreflap departures have been
attributed to inadequate lubrication of the outboard fitting assembly,
corrosion of the outboard fitting assembly, and corrosion in the
inboard link assembly. In addition, broken center toggle rollers at the
inboard sequence carriage and binding of inboard foreflap tracks due to
defective or seized foreflap track rollers can lead to higher than
normal loads on the outboard fitting assembly and the inboard link
assembly, which may lead to cracked or broken attachment fittings, and
in some cases the damage has resulted in an inboard foreflap departing
the airplane. This condition, if not addressed, could result in the
departure of an inboard foreflap assembly from the airplane possibly
resulting in damage to the airplane, and adversely affecting the
airplane's continued safe flight and landing.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin 747-57A2367 RB,
dated November 15, 2019. This service information describes procedures
for repetitive replacement of certain parts; a general visual
inspection to determine production configuration for certain parts; a
repetitive lubrication of certain parts and a repetitive general visual
inspection of certain parts for any exuding grease; repetitive detailed
inspections of certain parts for loose or missing attachment bolts,
cracks or bushing migration, cracks or gouges, or broken, binding, or
missing rollers; repetitive detailed inspections of certain parts for
cracks or corrosion; repetitive lubrication; and on-condition actions
if necessary. On-condition actions include replacements and repair.
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
The FAA is proposing this AD because the FAA 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 accomplishment of the actions
identified in Boeing Alert Requirements Bulletin 747-57A2367 RB, dated
November 15, 2019, 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-2020-0211.
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 125 airplanes of
U.S. registry. The FAA estimate the following costs to comply with this
proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------

[[Page 29675]]
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:
Estimated Costs of On-Condition Replacements

The FAA has received no definitive data that would enable the FAA
to provide cost estimates for the on-condition repairs 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 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
