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
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 NPRM, 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
NPRM. Submissions containing CBI
should be sent to the person identified
in the FOR FURTHER INFORMATION
CONTACT section. Any commentary that
the FAA receives which is not
specifically designated as CBI will be

Discussion
The FAA issued AD 2018–14–02,
Amendment 39–19322 (83 FR 31650,
July 9, 2018) (‘‘AD 2018–14–02’’), for
certain The Boeing Company Model
777–200, –200LR,
–300, and –300ER series airplanes.
AD 2018–14–02 requires an inspection
for foam insulation on the dripshield
above the overhead panel support
structure and replacement if necessary.
For certain airplanes, AD 2018–14–02
also requires replacement of foam
insulation on the overhead panel
support structure. AD 2018–14–02
resulted from reports that additional
areas of BMS 8–39 flexible urethane
foam were found during a routine
inspection pursuant to a previously
issued AD. The FAA issued AD 2018–
14–02 to address BMS 8–39 flexible
urethane foam found in certain areas of
an airplane, which, if exposed to an
ignition source, could cause loss of
control of the airplane during a fire.
Actions Since AD 2018–14–02 Was
Issued
Since the FAA issued AD 2018–14–
02, additional areas of BMS 8–39
flexible urethane foam were found on
PO 00000
Frm 00014
Fmt 4702
Sfmt 4702
the overhead panel support structure in
the flight compartment. Based on those
findings, the FAA has determined that
the inspections required by AD 2018–
14–02 are not adequate to ensure the
BMS 8–39 foam insulation was fully
removed from the overhead panel
support structure on certain airplanes,
and a new detailed inspection and
replacement are required.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Special
Attention Service Bulletin 777–25–
0621, Revision 2, dated February 28,
2020. This service information describes
procedures for removal and replacement
of the foam on the overhead panel
support structure; a general visual
inspection for foam insulation on the
dripshield above the overhead panel
support structure; a detailed inspection
for foam insulation on the overhead
panel support structure; and
replacement if necessary. 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 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
Although this proposed AD does not
explicitly restate the requirements of AD
2018–14–02, this proposed AD would
retain all of the requirements of AD
2018–14–02. Those requirements are
referenced in the service information
identified previously, which, in turn, is
referenced in paragraph (g) of this
proposed AD. This proposed AD would
also require accomplishment of the
actions identified as ‘‘RC’’ (required for
compliance) in the Accomplishment
Instructions of Boeing Special Attention
Service Bulletin 777–25–0621, Revision
2, dated February 28, 2020, described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.

The FAA estimates the following costs
to comply with this proposed AD:
ESTIMATED COSTS
Inspection and replacement of foam insulation (retained actions from AD 2018–14–

Up to 7,370
Up to 972,840
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.

Authority for This Rulemaking
The FAA has 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 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.

Administration (FAA), DOT.
ACTION: Supplemental notice of
proposed rulemaking (SNPRM);
reopening of comment period.
AGENCY:
The FAA is revising an earlier
proposal for Robinson Helicopter
Company (Robinson) Model R66
helicopters that proposed to require
replacing a certain part-numbered tail
rotor (T/R) drive shaft yoke assembly
(yoke assembly) and inspecting for
sealant. The NPRM was prompted by
reports of T/R drive shaft forward
hanger bearing failures. This action
revises the NPRM by expanding the
applicability, changing the proposed
requirements, and correcting
nomenclature. Since this imposes an
additional burden over that proposed in
the NPRM, the FAA is reopening the
comment period to allow the public the
chance to comment on these changes.
DATES: The comment period for the
NPRM published in the Federal
Register on March 30, 2018 (83 FR

RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2018-14-02, which applies to certain The Boeing Company Model 777-200,
-200LR, -300, and -300ER series airplanes. AD 2018-14-02 requires an
inspection for foam insulation on the dripshield above the overhead
panel support structure and replacement if necessary. For certain
airplanes, AD 2018-14-02 also requires replacement of foam insulation
on the overhead panel support structure. Since the FAA issued AD 2018-
14-02, additional areas of Boeing Material Specification (BMS) 8-39
flexible urethane foam were found on the overhead panel support
structure. This proposed AD would continue to require the actions in AD
2018-14-02, and, for certain airplanes, this proposed AD would require
an inspection of the foam insulation on the overhead panel support
structure, and replacement if necessary. 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 September
11, 2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
The FAA issued AD 2018-14-02, Amendment 39-19322 (83 FR 31650, July
9, 2018) (``AD 2018-14-02''), for certain The Boeing Company Model 777-
200, -200LR,
-300, and -300ER series airplanes. AD 2018-14-02 requires an
inspection for foam insulation on the dripshield above the overhead
panel support structure and replacement if necessary. For certain
airplanes, AD 2018-14-02 also requires replacement of foam insulation
on the overhead panel support structure. AD 2018-14-02 resulted from
reports that additional areas of BMS 8-39 flexible urethane foam were
found during a routine inspection pursuant to a previously issued AD.
The FAA issued AD 2018-14-02 to address BMS 8-39 flexible urethane foam
found in certain areas of an airplane, which, if exposed to an ignition
source, could cause loss of control of the airplane during a fire.
Actions Since AD 2018-14-02 Was Issued
Since the FAA issued AD 2018-14-02, additional areas of BMS 8-39
flexible urethane foam were found on the overhead panel support
structure in the flight compartment. Based on those findings, the FAA
has determined that the inspections required by AD 2018-14-02 are not
adequate to ensure the BMS 8-39 foam insulation was fully removed from
the overhead panel support structure on certain airplanes, and a new
detailed inspection and replacement are required.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Service Bulletin 777-25-
0621, Revision 2, dated February 28, 2020. This service information
describes procedures for removal and replacement of the foam on the
overhead panel support structure; a general visual inspection for foam
insulation on the dripshield above the overhead panel support
structure; a detailed inspection for foam insulation on the overhead
panel support structure; and replacement if necessary. 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 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
Although this proposed AD does not explicitly restate the
requirements of AD 2018-14-02, this proposed AD would retain all of the
requirements of AD 2018-14-02. Those requirements are referenced in the
service information identified previously, which, in turn, is
referenced in paragraph (g) of this proposed AD. This proposed AD would
also require accomplishment of the actions identified as ``RC''
(required for compliance) in the Accomplishment Instructions of Boeing
Special Attention Service Bulletin 777-25-0621, Revision 2, dated
February 28, 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-2020-0586.
[[Page 45359]]
Costs of Compliance
The FAA estimates that this proposed AD affects 132 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection and replacement of foam Up to 32 work-hours x $85 $5,611 Up to $8,331 Up to $1,099,692
insulation (retained actions from AD per hour = Up to $2,720.
2018-14-02).
Detailed inspection and replacement Up to 18 work-hours x $85 5,840 Up to 7,370 Up to 972,840
(new proposed action). per hour = Up to $1,530.
----------------------------------------------------------------------------------------------------------------
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 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:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2018-14-02, Amendment 39-19322 (83 FR 31650, July 9, 2018), and adding
the following new AD:
The Boeing Company:
Docket No. FAA-2020-0586; Product Identifier 2020-NM-066-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by September 11,
2020.
(b) Affected ADs
This AD replaces AD 2018-14-02, Amendment 39-19322 (83 FR 31650,
July 9, 2018) (``AD 2018-14-02'').
(c) Applicability
This AD applies to The Boeing Company Model 777-200, -200LR, -
300, and -300ER series airplanes, certificated in any category, as
identified in Boeing Special Attention Service Bulletin 777-25-0621,
Revision 2, dated February 28, 2020.
(d) Subject
Air Transport Association (ATA) of America Code 25, Equipment/
furnishings.
(e) Unsafe Condition
This AD was prompted by reports that additional areas of Boeing
Material Specification (BMS) 8-39 flexible urethane foam were found
on the overhead panel support structure in the flight compartment.
The degradation of the foam over time increases the potential for an
uncontrolled fire below the passenger compartment floor and other
locations outside the areas covered by smoke detection and fire
protection systems. The FAA is issuing this AD to address BMS 8-39
flexible urethane foam found in certain areas of an airplane, which,
if exposed to an ignition source, could cause loss of control of the
airplane during a fire.
(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 paragraph 1.E., ``Compliance,'' of
Boeing Special Attention Service Bulletin 777-25-0621, Revision 2,
dated February 28, 2020, do all applicable actions identified as
``RC'' (required for compliance) in, and in accordance with, the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 777-25-0621, Revision 2, dated February 28, 2020.
(h) Exceptions to Service Information Specifications
(1) Where Boeing Special Attention Service Bulletin 777-25-0621,
Revision 2, dated February 28, 2020, uses the phrase ``the Revision
2 date of this service bulletin,'' this AD requires using ``the
effective date of AD 2018-14-02.''
(2) For any Group 1 Configuration 3 airplane as identified in
Boeing Special Attention Service Bulletin 777-25-0621, Revision 2,
dated February 28, 2020, no action is required by this AD, provided
that airplane remains in that configuration.
(i) 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 (j)(1) of this AD. Information may be
emailed to: [email protected].
(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
[[Page 45360]]
AD if it is approved by The Boeing Company Organization Designation
Authorization (ODA) that has been authorized by the Manager, Seattle
ACO Branch, FAA, 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) AMOCs approved previously for AD 2018-14-02 are approved as
AMOCs for the corresponding provisions of Boeing Special Attention
Service Bulletin 777-25-0621, Revision 2, dated February 28, 2020,
that are required by paragraph (g) of this AD.
(5) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(i)(5)(i) and (ii) of this AD apply.
(i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. If a step or 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 approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.
