conditions at the front flange scallops of
affected low-pressure compressor (LPC)
booster rotors. This proposed AD would
require repetitive fluorescent penetrant
inspections (FPIs) of the front flange
scallops of the LPC booster rotor for any
cracks, replacement or repair of the LPC
booster rotor if necessary and, as an
optional terminating action to the
repetitive FPIs, a visual inspection for
malformed scallop edge geometry and
malformed surface conditions, 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.

Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2022–0252,
dated December 16, 2022 (EASA AD
2022–0252) (referred to after this as the
MCAI), to correct an unsafe condition
E:\FR\FM\14JNP1.SGM
14JNP1
Federal Register / Vol. 88, No. 114 / Wednesday, June 14, 2023 / Proposed Rules
for all RRD Model BR700–715A1–30,
BR700–715B1–30, and BR700–715C1–
30 engines. The MCAI states that
occurrences have been reported of
finding malformed scallop edge
geometry and surface conditions at the
front flange scallops of certain LPC
booster rotors. To address this unsafe
condition, the manufacturer published
service information that specifies
procedures for inspecting the front
flange scallops of the LPC booster rotors
with accept and reject criteria. This
condition, if not addressed, could lead
to failure of the LPC booster rotor,
resulting in release of high-energy
debris, with consequent engine in-flight
shutdown, and reduced control of the
airplane.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2023–1211.
Related Service Information Under 1
CFR Part 51
The FAA reviewed EASA AD 2022–
0252, which specifies procedures for
accomplishing repetitive FPIs (on-wing
or in-shop) of the front flange scallops
of the affected part and, if any cracks are
detected, removing the engine from
service and contacting the manufacturer
for approved corrective actions. EASA
AD 2022–0252 also specifies procedures
for performing a visual inspection,
taking photographs, and submitting
photograph documentation of the LPC
booster rotor front flange scallops for
malformed scallop edge geometry and
malformed surface conditions,
including validation of the results from
the manufacturer, as terminating action
for the repetitive FPIs.
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 ADDRESSES.
FAA’s Determination
These products have been approved
by the aviation authority of another
country and are approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with this
State of Design Authority, it has notified
the FAA of the unsafe condition
described in the MCAI described above.
The FAA is issuing this NPRM after
determining that the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design.
Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
the MCAI, except as discussed under
‘‘Differences Between this Proposed AD
and the MCAI,’’ and under Exceptions
to EASA AD 2022–0252.
Explanation of Required Compliance
Information
In the FAA’s ongoing efforts to
improve the efficiency of the AD
process, the FAA developed a process to
use some civil aviation authority (CAA)
ADs as the primary source of
information for compliance with
requirements for corresponding FAA
ADs. The FAA has since coordinated
with other manufacturers and CAAs to
use this process. As a result, the FAA
proposes to incorporate by reference
EASA AD 2022–0252 in the FAA final
rule. This proposed AD would,
therefore, require compliance with
EASA AD 2022–0252 in its entirety
38763
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 within the compliance times,’’
compliance with this AD requirement is
not limited to the section titled
‘‘Required Action(s) and Compliance
Time(s)’’ in EASA AD 2022–0252.
Service information required by the
EASA AD for compliance will be
available at regulations.gov by searching
for and locating Docket No. FAA–2023–
1211 after the FAA final rule is
published.
Differences Between This Proposed AD
and the MCAI
Where paragraph (2) of EASA AD
2022–0252 specifies to contact RRD for
approved corrective action(s) and
accomplish those actions accordingly,
this proposed AD would require
replacement or repair of the LPC booster
rotor.
Where paragraph (3) of EASA AD
2022–0252 specifies to contact RRD for
approved corrective action(s) and
accomplish those actions accordingly,
this proposed AD would require
replacement or repair of the LPC booster
rotor.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 148
engines installed on airplanes of U.S.
registry.
The FAA estimates the following
costs to comply with this proposed AD:

ddrumheller on DSK120RN23PROD with PROPOSALS1
The FAA estimates the following
costs to do any necessary replacement,
repair, or visual inspection that would
be required based on the results of the
proposed inspection. Operators have the
option of performing a visual inspection
of the affected LPC booster rotor as an
optional terminating action for the
repetitive FPIs. The agency has no way
of determining the number of aircraft
that might need this replacement,
repair, or visual inspection:

Paperwork Reduction Act
Regulatory Findings
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to a penalty for failure to comply with
a collection of information subject to the
requirements of the Paperwork
Reduction Act unless that collection of
information displays a current valid
OMB Control Number. The OMB
Control Number for this information
collection is 2120–0056. Public
reporting for this collection of
information is estimated to take
approximately 1 hour per response,
including the time for reviewing
instructions, searching existing data
sources, gathering and maintaining the
data needed, and completing and
reviewing the collection of information.
All responses to this collection of
information are mandatory if operators
elect to perform the optional
terminating action. Send comments
regarding this burden estimate or any
other aspect of this collection of
information, including suggestions for
reducing this burden, to: Information
Collection Clearance Officer, Federal
Aviation Administration, 10101
Hillwood Parkway, Fort Worth, TX
76177–1524.
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) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
Authority for This Rulemaking
PART 39—AIRWORTHINESS
DIRECTIVES
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.

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG
Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-715A1-30,
BR700-715B1-30, and BR700-715C1-30 engines. This proposed AD was
prompted by reports of malformed scallop edge geometry and surface
conditions at the front flange scallops of affected low-pressure
compressor (LPC) booster rotors. This proposed AD would require
repetitive fluorescent penetrant inspections (FPIs) of the front flange
scallops of the LPC booster rotor for any cracks, replacement or repair
of the LPC booster rotor if necessary and, as an optional terminating
action to the repetitive FPIs, a visual inspection for malformed
scallop edge geometry and malformed surface conditions, 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.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0252, dated December 16, 2022
(EASA AD 2022-0252) (referred to after this as the MCAI), to correct an
unsafe condition
[[Page 38763]]
for all RRD Model BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30
engines. The MCAI states that occurrences have been reported of finding
malformed scallop edge geometry and surface conditions at the front
flange scallops of certain LPC booster rotors. To address this unsafe
condition, the manufacturer published service information that
specifies procedures for inspecting the front flange scallops of the
LPC booster rotors with accept and reject criteria. This condition, if
not addressed, could lead to failure of the LPC booster rotor,
resulting in release of high-energy debris, with consequent engine in-
flight shutdown, and reduced control of the airplane.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-1211.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2022-0252, which specifies procedures for
accomplishing repetitive FPIs (on-wing or in-shop) of the front flange
scallops of the affected part and, if any cracks are detected, removing
the engine from service and contacting the manufacturer for approved
corrective actions. EASA AD 2022-0252 also specifies procedures for
performing a visual inspection, taking photographs, and submitting
photograph documentation of the LPC booster rotor front flange scallops
for malformed scallop edge geometry and malformed surface conditions,
including validation of the results from the manufacturer, as
terminating action for the repetitive FPIs.
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 ADDRESSES.
FAA's Determination
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI described above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the MCAI, except as discussed under ``Differences Between this
Proposed AD and the MCAI,'' and under Exceptions to EASA AD 2022-0252.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has since
coordinated with other manufacturers and CAAs to use this process. As a
result, the FAA proposes to incorporate by reference EASA AD 2022-0252
in the FAA final rule. This proposed AD would, therefore, require
compliance with EASA AD 2022-0252 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 within the
compliance times,'' compliance with this AD requirement is not limited
to the section titled ``Required Action(s) and Compliance Time(s)'' in
EASA AD 2022-0252. Service information required by the EASA AD for
compliance will be available at regulations.gov by searching for and
locating Docket No. FAA-2023-1211 after the FAA final rule is
published.
Differences Between This Proposed AD and the MCAI
Where paragraph (2) of EASA AD 2022-0252 specifies to contact RRD
for approved corrective action(s) and accomplish those actions
accordingly, this proposed AD would require replacement or repair of
the LPC booster rotor.
Where paragraph (3) of EASA AD 2022-0252 specifies to contact RRD
for approved corrective action(s) and accomplish those actions
accordingly, this proposed AD would require replacement or repair of
the LPC booster rotor.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 148 engines installed on 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.

----------------------------------------------------------------------------------------------------------------
FPI front flange scallops of the LPC 5 work-hours x $85 per $0 $425 $62,900
booster rotor. hour = $425.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacement, repair, or visual inspection that would be required based
on the results of the proposed inspection. Operators have the option of
performing a visual inspection of the affected LPC booster rotor as an
optional terminating action for the repetitive FPIs. The agency has no
way of determining the number of aircraft that might need this
replacement, repair, or visual inspection:

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to take
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory if operators elect to perform the optional
terminating action. Send comments regarding this burden estimate or any
other aspect of this collection of information, including suggestions
for reducing this burden, to: Information Collection Clearance Officer,
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX
76177-1524.
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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
