AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
Airbus Helicopters Model SA330J
helicopters, all serial numbers. This
proposed AD was prompted by reports
of the failure of the lower bearing cage
of the main rotor hub (MRH) flapping
hinges and of the presence of metallic
particles at the bottom of a drag hinge.
This proposed AD would require
repetitive inspections of the MRH chip
detectors, or for helicopters not
equipped with chip detectors, repetitive
inspections of the oil for contamination
by metallic particles, and corrective
actions if necessary, as specified in a
European Union Aviation Safety Agency
(EASA) AD, which is proposed for
incorporation by reference (IBR). The
FAA is proposing this AD to address the
unsafe condition on these products.

Discussion
The EASA, which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2019–0157, dated July 3, 2019 (EASA
AD 2019–0157) (also referred to as the
Mandatory Continuing Airworthiness
Information, or the MCAI), to correct an
unsafe condition for Airbus Helicopters
Model SA330J helicopters, all serial
numbers.
This proposed AD was prompted by
reports of failure of the lower bearing
cage of the MRH flapping hinges and
presence of metallic particles at the
bottom of a drag hinge. The FAA is
proposing this AD to address failure of
the lower bearing cage of the MRH
flapping hinges and presence of metallic
particles at the bottom of a drag hinge,
which could lead to loss of flapping
hinge function, resulting in MRH
unbalance and loss of control of the
helicopter. See the MCAI for additional
background information.
Related Service Information Under 1
CFR Part 51
EASA AD 2019–0157 describes
procedures for repetitive inspections of
the MRH chip detectors, or for
helicopters not equipped with chip
detectors, repetitive inspections of the
oil for contamination by metallic
particles, and corrective actions if
necessary. Corrective actions include
replacement of the incidence hinge
bearings, replacement of the flapping
bearing race and bearing or if there is no
degradation reinstallation of the bearing
race and bearing 180° from the marked
position during removal, and
replacement of the drag lower bearing
race and bearing. This material 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 and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to the
bilateral agreement with the State of
Design Authority, the FAA has been
notified of the unsafe condition
described in the MCAI referenced
above. The FAA is proposing this AD
after evaluating all the relevant
information and determining the unsafe
condition described previously is likely
to exist or develop in other products of
the same type designs.
Proposed AD Requirements
This proposed AD would require
accomplishing the actions specified in
EASA AD 2019–0157, described
previously, as incorporated by
reference, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
Explanation of Required Compliance
Information
In the FAA’s ongoing efforts to
improve the efficiency of the AD
process, the FAA initially worked with
Airbus and EASA to develop a process
to use certain EASA ADs as the primary
source of information for compliance
with requirements for corresponding
FAA ADs. The FAA has since
coordinated with other manufacturers
and civil aviation authorities (CAAs) to
use this process. As a result, EASA AD
2019–0157 will be incorporated by
reference in the FAA final rule. This
proposed AD would, therefore, require
compliance with EASA AD 2019–0157
in its entirety, through that
incorporation, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
Using common terms that are the same
as the heading of a particular section in
the EASA AD does not mean that
operators need comply only with that
section. For example, where the AD
requirement refers to ‘‘all required
actions and compliance times,’’
compliance with this AD requirement is
not limited to the section titled
‘‘Required Action(s) and Compliance
Time(s)’’ in the EASA AD. Service
information specified in EASA AD
2019–0157 that is required for
compliance with EASA AD 2019–0157
will be available on the internet at
https://www.regulations.gov by
searching for and locating Docket No.
FAA–2021–0297 after the FAA final
rule is published.
Interim Action
The FAA considers this proposed AD
interim action. The investigation to
detect the root cause of the reported
failures of the lower bearing cage of the
MRH flapping hinges and presence of
metallic particles at the bottom of the
drag hinge is on-going.
Costs of Compliance
The FAA estimates that this proposed
AD affects 4 helicopters of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:

Labor cost
Parts cost
Cost per
product
Cost on U.S.

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.
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.

AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain The Boeing Company Model
747–400, 747–400D, and 747–400F
series airplanes. This proposed AD was
prompted by reports of burned Boeing
Material Specification (BMS) 8–39
urethane foam found in certain
locations on the airplane; investigation
revealed that the fire-retardant
properties degrade with age. This
proposed AD would require inspecting
the insulation blankets in certain areas
of the forward cargo compartment for
exposed BMS 8–39 urethane foam, not
encapsulated by a protective fire
resistant barrier, and for seal integrity,
and replacing the BMS 8–39 urethane
foam and seal if necessary. The FAA is
proposing this AD to address the unsafe
condition on these products.

Background
The FAA has received reports of
burned BMS 8–39 urethane foam, a
material with fire-retardant properties.
Investigation revealed that the fireretardant properties degrade after five to
ten years, and degraded BMS 8–39
urethane foam can be a fuel source for
a fire if exposed to an ignition source.
Foam and tape are used to make a seal
at penetrations that go through the
insulation blankets. The type of foam
that is used, how that foam is installed,
and how it is taped are all equally
important for the integrity of the seal.
Previously issued service information
provided procedures for replacing the
BMS 8–39 urethane foam in most areas,
but it did not include an area between
body station (STA) 960 and STA 1000
on the left and right sides of the forward
cargo compartment. Degraded BMS 8–
39 urethane foam used in seals may fail
to maintain sufficient halon
concentrations in the cargo
compartments to extinguish or contain
fire or smoke, and may fail to prevent
penetration of fire or smoke in areas of
the airplane that are difficult to access
for fire and smoke detection or
suppression, which could result in loss
of control of the airplane.

RIN 2120-AA64
Airworthiness Directives; Airbus Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for Airbus Helicopters Model SA330J helicopters, all serial numbers.
This proposed AD was prompted by reports of the failure of the lower
bearing cage of the main rotor hub (MRH) flapping hinges and of the
presence of metallic particles at the bottom of a drag hinge. This
proposed AD would require repetitive inspections of the MRH chip
detectors, or for helicopters not equipped with chip detectors,
repetitive inspections of the oil for contamination by metallic
particles, and corrective actions if necessary, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is proposed for
incorporation by reference (IBR). The FAA is proposing this AD to
address the unsafe condition on these products.

Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2019-0157, dated July 3, 2019 (EASA
AD 2019-0157) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for Airbus Helicopters Model SA330J helicopters, all serial numbers.
This proposed AD was prompted by reports of failure of the lower
bearing cage of the MRH flapping hinges and presence of metallic
particles at the bottom of a drag hinge. The FAA is proposing this AD
to address failure of the lower bearing cage of the MRH flapping hinges
and presence of metallic particles at the bottom of a drag hinge, which
could lead to loss of flapping hinge function, resulting in MRH
unbalance and loss of control of the helicopter. See the MCAI for
additional background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2019-0157 describes procedures for repetitive inspections
of the MRH chip detectors, or for helicopters not equipped with chip
detectors, repetitive inspections of the oil for contamination by
metallic particles, and corrective actions if necessary. Corrective
actions include replacement of the incidence hinge bearings,
replacement of the flapping bearing race and bearing or if there is no
degradation reinstallation of the bearing race and bearing 180[deg]
from the marked position during removal, and replacement of the drag
lower bearing race and bearing. This material 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 and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the bilateral agreement with the State of Design Authority, the FAA
has been notified of the unsafe condition described in the MCAI
referenced above. The FAA is proposing this AD after evaluating all the
relevant information and determining the unsafe condition described
previously is likely to exist or develop in other products of the same
type designs.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified
in EASA AD 2019-0157, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2019-0157
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2019-0157 in its
entirety, through that incorporation, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance Time(s)'' in the EASA AD. Service information specified
in EASA AD 2019-0157 that is required for compliance with EASA AD 2019-
0157 will be available on the internet at https://www.regulations.gov
by searching for and locating Docket No. FAA-2021-0297 after the FAA
final rule is published.
Interim Action
The FAA considers this proposed AD interim action. The
investigation to detect the root cause of the reported failures of the
lower bearing cage of the MRH flapping hinges and presence of metallic
particles at the bottom of the drag hinge is on-going.
Costs of Compliance
The FAA estimates that this proposed AD affects 4 helicopters of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340........................... $0 $340 $1,360
----------------------------------------------------------------------------------------------------------------
[[Page 19159]]
The FAA estimates the following costs to do any necessary on-
condition replacements that would be required based on the results of
any required actions. The FAA has no way of determining the number of
helicopters that might need these on-condition replacements:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
24 work-hours x $85 per hour = $2,040......................................... $53,025.29 $55,065.29
----------------------------------------------------------------------------------------------------------------
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
