Abstract
The FAA is superseding four airworthiness directives (ADs) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37 engines. The superseded ADs required recalculating the cyclic life for certain engine life-limited rotating parts and replacing those parts that have exceeded their cyclic life limit within specified compliance times. Since the FAA issued those ADs, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD requires revising the airworthiness limitations section (ALS) of the existing approved maintenance or inspection program, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG
Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding four airworthiness directives (ADs) for
all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535E4-37,
RB211-535E4-B-37, and RB211-535E4-C-37 engines. The superseded ADs
required recalculating the cyclic life for certain engine life-limited
rotating parts and replacing those parts that have exceeded their
cyclic life limit within specified compliance times. Since the FAA
issued those ADs, the manufacturer has revised the engine time limits
manual (TLM), introducing new and more restrictive instructions. This
AD requires revising the airworthiness limitations section (ALS) of the
existing approved maintenance or inspection program, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is incorporated
by reference. The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective June 27, 2024.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 27,
2024.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2003-17-15, Amendment 39-13290 (68 FR
51682, August 28, 2003) (AD 2003-17-15); AD 2013-19-17, Amendment 39-
17599 (78 FR 61171, October 3, 2013; corrected November 14, 2013 (78 FR
68360)) (AD 2013-19-17); AD 2013-19-18, Amendment 39-17600 (78 FR
61168, October 3, 2013) (AD 2013-19-18); AD 2015-17-21, Amendment 39-
18254 (80 FR 65925, October 28, 2015) (AD 2015-17-21); and AD 2016-03-
04, Amendment 39-18391 (81 FR 6755, February 9, 2016) (AD 2016-03-04)
for RRD Model RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37
engines. The NPRM also affected AD 2004-19-04, Amendment 39-13798 (69
FR 56683, September 22, 2004; corrected September 30, 2004 (69 FR
58257)) (AD 2004-19-04) for Model RB211-22B, RB211-524, and RB211-535
series engines. Those ADs required recalculating the cyclic life for
certain engine life-limited rotating parts, replacing those parts that
have exceeded their cyclic life limit within specified compliance
times, and revising the engine TLM. The FAA issued those ADs to prevent
failure of critical life-limited rotating engine parts, which could
result in uncontained parts release, uncontained engine failure, damage
to the engine, and damage to the airplane.
The NPRM published in the Federal Register on August 4, 2023 (88 FR
51742). The NPRM was prompted by EASA AD 2022-0235, dated December 1,
2022 (EASA AD 2022-0235) (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 the manufacturer published a
revised engine TLM introducing new or more restrictive tasks and
limitations. These new or more restrictive tasks and limitations
include updating declared lives of certain critical parts.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1652.
In the NPRM, the FAA proposed to retain none of the requirements of
AD 2003-17-15, AD 2013-19-17, AD 2013-19-18, AD 2015-17-21, and AD
2016-03-04. The NPRM proposed to require revising the existing approved
maintenance or inspection program, as applicable, to incorporate more
restrictive airworthiness limitations, as specified in EASA AD 2022-
0235. The
[[Page 45565]]
NPRM also proposed to terminate all requirements of AD 2004-19-04 for
Model RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37 engines
only.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from three commenters. The commenters
were the Air Line Pilots Association, International (ALPA), Boeing, and
StandardAero. ALPA and Boeing supported the NPRM without change. The
following presents the comment received on the NPRM and the FAA's
response.
Request To Consider Artificial Aging Requirements in AD 2016-03-04
StandardAero noted that AD 2016-03-04 incorporates the new life as
published in the latest TLM revision and applies an artificial aging
calculation that is not included in the TLM revision for specific part
numbers. The commenter asked the FAA to clarify if the artificial aging
calculation required by AD 2016-03-04 is no longer required.
The FAA agrees that the artificial aging calculation for components
that is specified in RRD Alert Non-Modification Service Bulletin No.
RB.211-72-AH972, Revision 3, dated August 28, 2015, and required by AD
2016-03-04, is necessary to evaluate the total life consumed for the
applicable parts. Therefore, the FAA has determined not to supersede AD
2016-03-04 and has revised this final rule accordingly.
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 comments received, 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, and any other changes described previously,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed EASA AD 2022-0235, which specifies instructions
for accomplishing the actions specified in the applicable engine TLM,
including performing maintenance tasks, replacing life-limited parts,
and revising the existing approved maintenance or inspection program,
as applicable, by incorporating the limitations, tasks, and associated
thresholds and intervals described 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 468 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:

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
The FAA has determined that 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.
