airworthiness directive (AD) for all
Rolls-Royce Deutschland Ltd. & Co. KG
(RRD) Model RB211 Trent 768–60, 772–
60, and 772B–60 engines. This AD was
prompted by reports of cracks on

SUPPLEMENTARY INFORMATION:
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all RRD Model RB211 Trent
768–60, 772–60, and 772B–60 engines.
The NPRM published in the Federal
Register on June 14, 2023 (88 FR 38759).
The NPRM was prompted by AD 2022–
0055, dated March 23, 2022 (EASA AD
2022–0055) (also referred to as the
MCAI), issued by EASA, which is the
Technical Agent for the Member States
of the European Union. The MCAI states
that cracking on the IPC rotor shaft
balance land has been historically
observed on RRD Model Trent 700
engines. To address this unsafe
condition, Rolls-Royce plc (RR)
originally developed Modification 72–
AG402, which introduced a revised
balancing method that removed the
original balancing weights from the IPC
rotor shaft balance land and published
RR Service Bulletin (SB) RB.211–72–
E:\FR\FM\21SER1.SGM
21SER1
Federal Register / Vol. 88, No. 182 / Thursday, September 21, 2023 / Rules and Regulations
AG402 to provide instructions for an inservice modification. In addition, RR
published Non-Modification Service
Bulletin (NMSB) RB.211–72–AG085,
Revision 3, dated August 27, 2021, to
provide instructions for an in-shop eddy
current inspection (ECI) of the IPC rotor
shaft balance land. Consequently, EASA
issued EASA AD 2018–0049R2, dated
September 13, 2021 (EASA AD 2018–
0049R2).
Since EASA issued EASA AD 2018–
0049R2, RR determined that some RRD
Model Trent 700 engines (post-RR SB
RB.211–72–AG402) were not inspected
in accordance with RR NMSB RB.211–
72–AG085 during engine refurbishment
due to the policy applied previously
from RR NMSB RB.211–72–AG085,
Revision 2. RR identified the affected
batch of IPC rotor shaft balance lands
and published RR NMSB RB.211–72–
AK706, Initial Issue, dated November
24, 2021, which describes procedures to
perform a BSI of the IPC rotor shaft
balance land until the in-shop ECI is
accomplished in accordance with RR
NMSB RB.211–72–AG085. To address
this, EASA issued the MCAI.
In the NPRM, the FAA proposed to
require accomplishing the actions
specified in the MCAI described
previously, except for any differences
identified as exceptions in the
regulatory text. The FAA is issuing this
AD to address the unsafe condition on
these products.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2023–1212.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
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 referenced
above. The FAA reviewed the relevant
data and determined that air safety
requires adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products. Except for minor editorial
changes, this AD is adopted as proposed
in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed EASA AD 2022–
0055, which specifies procedures for
65119
performing repetitive on-wing or inshop BSIs of the IPC rotor shaft balance
land and, if any discrepancies are
detected, accomplishing the applicable
corrective actions or replacing the IPC
rotor shaft. The MCAI also specifies
prohibiting the installation of an
affected IPC rotor shaft on any engine
and that accomplishing an in-shop ECI
of the IPC rotor shaft balance land or
replacing the IPC rotor shaft constitutes
as terminating action for the repetitive
BSIs.
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 ADDRESSES.
Differences Between This AD and the
MCAI
EASA AD 2022–0055 applies to RRD
Model RB211 Trent 768–60, 772–60,
772B–60, and 772C–60 engines. This
AD does not apply to RRD Model RB211
Trent 772C–60 engines, as this model
engine does not have an FAA type
certificate.
Costs of Compliance
The FAA estimates that this AD
affects 62 engines installed on airplanes
of U.S. registry.
The FAA estimates the following
costs to comply with this AD:
ESTIMATED COSTS

results of the inspection. The agency has
no way of determining the number of
aircraft that might need these
replacements:

AG402, which introduced a revised balancing method that removed the
original balancing weights from the IPC rotor shaft balance land and
published RR Service Bulletin (SB) RB.211-72-
[[Page 65119]]
AG402 to provide instructions for an in-service modification. In
addition, RR published Non-Modification Service Bulletin (NMSB) RB.211-
72-AG085, Revision 3, dated August 27, 2021, to provide instructions
for an in-shop eddy current inspection (ECI) of the IPC rotor shaft
balance land. Consequently, EASA issued EASA AD 2018-0049R2, dated
September 13, 2021 (EASA AD 2018-0049R2).
Since EASA issued EASA AD 2018-0049R2, RR determined that some RRD
Model Trent 700 engines (post-RR SB RB.211-72-AG402) were not inspected
in accordance with RR NMSB RB.211-72-AG085 during engine refurbishment
due to the policy applied previously from RR NMSB RB.211-72-AG085,
Revision 2. RR identified the affected batch of IPC rotor shaft balance
lands and published RR NMSB RB.211-72-AK706, Initial Issue, dated
November 24, 2021, which describes procedures to perform a BSI of the
IPC rotor shaft balance land until the in-shop ECI is accomplished in
accordance with RR NMSB RB.211-72-AG085. To address this, EASA issued
the MCAI.
In the NPRM, the FAA proposed to require accomplishing the actions
specified in the MCAI described previously, except for any differences
identified as exceptions in the regulatory text. The FAA is issuing
this AD to address the unsafe condition on these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2023-1212.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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 referenced above. The FAA reviewed the relevant data and
determined that air safety requires adopting this AD as proposed.
Accordingly, the FAA is issuing this AD to address the unsafe condition
on these products. Except for minor editorial changes, this AD is
adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2022-0055, which specifies procedures for
performing repetitive on-wing or in-shop BSIs of the IPC rotor shaft
balance land and, if any discrepancies are detected, accomplishing the
applicable corrective actions or replacing the IPC rotor shaft. The
MCAI also specifies prohibiting the installation of an affected IPC
rotor shaft on any engine and that accomplishing an in-shop ECI of the
IPC rotor shaft balance land or replacing the IPC rotor shaft
constitutes as terminating action for the repetitive BSIs.
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 ADDRESSES.
Differences Between This AD and the MCAI
EASA AD 2022-0055 applies to RRD Model RB211 Trent 768-60, 772-60,
772B-60, and 772C-60 engines. This AD does not apply to RRD Model RB211
Trent 772C-60 engines, as this model engine does not have an FAA type
certificate.
Costs of Compliance
The FAA estimates that this AD affects 62 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
BSI of IPC rotor shaft balance land. 4.50 work-hours x $85 $0 $382.50 $23,715
per hour = $382.50.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need these replacements:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace IPC rotor shaft...................... 50 work-hours x $85 per hour = $2,120,000 $2,124,250
$4,250.
----------------------------------------------------------------------------------------------------------------
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
This AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
[[Page 65120]]
(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.
