Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37 engines. This proposed AD was 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 proposed AD would require 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 proposing this AD to address the unsafe condition on these products.

-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37
engines. This proposed AD was 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 proposed AD would require
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 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 2022-0236, dated December 1, 2022
(EASA AD 2022-0236) (referred to after this as the MCAI), to address an
unsafe condition for all RRD Model RB211-535C-37 engines. 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.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1210.
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.
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 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
proposed AD and as discussed under ``Differences Between this Proposed
AD and the EASA AD.''
Differences Between This Proposed AD and the EASA AD
Where paragraph (3) of EASA AD 2022-0236 specifies revising the
approved Aircraft Maintenance Programme within 12 months after the
effective date of EASA AD 2022-0236, this proposed AD would require
revising the ALS of the existing approved engine maintenance or
inspection program, as applicable, within 90 days after the effective
date of this AD.
This proposed AD would not require compliance with paragraphs (1),
(2), (4), and (5) of EASA AD 2022-0236.
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 2022-0236
in the FAA final rule. This proposed AD would, therefore, require
compliance with EASA AD 2022-0236 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
EASA AD 2022-0236. Service information required by the EASA AD for
compliance will be available at <a href="http://regulations.gov">regulations.gov</a> by searching for and
locating Docket No. FAA-2023-1210 after the FAA final rule is
published. Service information required by the EASA AD for compliance
will be available at <a href="http://regulations.gov">regulations.gov</a> by searching for and locating
Docket No. FAA-2023-1210 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 2 engines installed on airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:

----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

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
[[Page 38411]]
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.
