Abstract
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37 engines. This AD is prompted by the manufacturer revising the existing engine time limits manual (TLM) to introduce new or more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts. This AD requires revising the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive instructions and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37 engines.
This AD is prompted by the manufacturer revising the existing engine
time limits manual (TLM) to introduce new or more restrictive
airworthiness limitations and associated thresholds and intervals for
life-limited parts. This AD requires revising the airworthiness
limitations section (ALS) of the operator's existing approved engine
maintenance or inspection program, as applicable, to incorporate new or
more restrictive instructions and associated thresholds and intervals
for life-limited parts, as specified in a European Union Aviation
Safety Agency (EASA) AD, which is proposed for incorporation by
reference (IBR). The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective October 30, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 30,
2023.

SUPPLEMENTARY INFORMATION:
Background
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-
535C-37 engines. The NPRM published in the Federal Register on June 13,
2023 (88 FR 38409). The NPRM was prompted by AD 2022-0236, dated
December 1, 2022 (EASA AD 2022-0236) (also referred to after this as
the MCAI), issued by EASA, which is the Technical Agent for the Member
States of the European Union. The MCAI states that the ALS for RB211-
535C-37 engines, which is approved by EASA, is defined and published in
TLM T-211(535)-5RR, and that these airworthiness limitations have been
identified as mandatory for continued airworthiness. The MCAI also
states that the manufacturer published a revised engine TLM to
introduce new or more restrictive instructions and associated
thresholds and intervals for life-limited parts.
In the NPRM, the FAA proposed to require revising the ALS of the
operator's existing approved engine maintenance or inspection program,
as applicable, to incorporate new or more restrictive instructions and
associated thresholds and intervals for life-limited parts, which are
specified in EASA AD 2022-0236, described previously, except for any
differences identified as exceptions in the regulatory text of this AD.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1210.
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from The Boeing Company, who supported
the NPRM without change.
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,
considered the comment received, and determined that air safety
requires adopting the 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 2022-0236, which specifies procedures for
operators to revise the ALS of their existing approved engine
maintenance or inspection program to incorporate new or more
restrictive instructions and associated thresholds and intervals for
life-limited parts described in the revised engine TLM, as applicable
to each engine model. EASA AD 2022-0236 also describes actions for
replacing life-limited parts, performing maintenance tasks, and
performing corrective actions for any finding of discrepancy as
referenced in the engine TLM.
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.
Costs of Compliance
The FAA estimates that this AD affects 2 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:

maintenance or inspection program.
----------------------------------------------------------------------------------------------------------------
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:
(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.

(e) Unsafe Condition
This AD was prompted by the manufacturer revising the engine
time limits manual (TLM) to introduce new or more restrictive
instructions and associated thresholds and intervals for life-
limited parts. The FAA is issuing this AD to prevent failure of
life-limited parts. The unsafe condition, if not addressed, could
result in uncontained release of a critical part, damage to the
engine, and damage to the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Except as specified in paragraph (h) of this AD: Perform all
required actions within the compliance times specified in, and in

(1) Where EASA AD 2022-0236 defines the AMP as the approved
Aircraft Maintenance Programme containing the tasks on the basis of
which the scheduled maintenance is conducted to ensure the
continuing airworthiness of each operated engine, this AD defines
the AMP as the aircraft maintenance program containing the tasks on
the basis of which the scheduled maintenance is conducted to ensure
the continuing airworthiness of each operated airplane.
(2) Where EASA AD 2022-0236 refers to its effective date, this
AD requires using the effective date of this AD.

(4) Where paragraph (3) of EASA AD 2022-0236 specifies revising
the approved AMP within 12 months after the effective date of EASA
AD 2022-0236, this AD requires revising the airworthiness
limitations section of the existing approved engine maintenance or
inspection program, as applicable, within 90 days after the
effective date of this AD.
(5) This AD does not adopt the Remarks paragraph of EASA AD
2022-0236.
(i) Provisions for Alternative Actions and Intervals
After performing the actions required by paragraph (g) of this
AD, no alternative actions and associated thresholds and intervals,
including life limits, are allowed unless they are approved as
specified in the provisions of the ``Ref. Publications'' section of
EASA AD 2022-0236.
