Abstract
The FAA is superseding Airworthiness Directive (AD) 2013-26-10 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211- 524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19 engines. AD 2013-26-10 required a one-time reduction in the cyclic life of certain high-pressure compressor (HPC) rotor stage 1 and stage 2 disks, and removal of disks that exceed the reduced cycle life. Since the FAA issued AD 2013-26-10, the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This AD is prompted by the manufacturer revising the engine time limits manual, introducing new and more restrictive instructions. This AD requires revisions to the airworthiness limitations section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, 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.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2013-26-10
for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-
524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19 engines. AD
2013-26-10 required a one-time reduction in the cyclic life of certain
high-pressure compressor (HPC) rotor stage 1 and stage 2 disks, and
removal of disks that exceed the reduced cycle life. Since the FAA
issued AD 2013-26-10, the manufacturer has revised the engine time
limits manual (TLM), introducing new and more restrictive instructions.
This AD is prompted by the manufacturer revising the engine time limits
manual, introducing new and more restrictive instructions. This AD
requires revisions to the airworthiness limitations section (ALS) of
the operator's existing approved engine maintenance or inspection
program, as applicable, 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 December 11, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 11,
2023.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2013-26-10, Amendment 39-17719 (79 FR 1315,
January 8, 2014), (AD 2013-26-10). AD 2013-26-10 applied to certain RRD
Model RB211-524G2-19, RB211-524G3-19, RB211-524H-36, and RB211-524H2-19
engines. AD 2013-26-10 required a one-time reduction in the cyclic life
of certain HPC rotor stage 1 and stage 2 disks, and removal of disks
that exceed the reduced cycle life. The FAA issued AD 2013-26-10 to
prevent the failure of certain life-limited parts, which could result
in uncontained engine damage and damage to the airplane.
The NPRM published in the Federal Register on July 11, 2023 (88 FR
44075). The NPRM was prompted by AD 2022-0232, dated November 28, 2022
(EASA AD 2022-0232) (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 RB211-524G/H engines, which is
approved by EASA, is defined and published in TLM T-211(524)-7RR, and
that these airworthiness limitations have been identified as mandatory
for continued airworthiness. The MCAI also states that since the
original issue of TLM T-211(524)-7RR, updated thresholds and intervals
were introduced for newly designed parts. EASA AD 2013-0246 was issued
to require implementation of the reduced cyclic life limit and
replacement of HPC stage 1 and 2 disks before exceeding their life
limit. The MCAI also states that the manufacturer published a revised
engine TLM since EASA AD 2013-0246 was issued, introducing new and more
restrictive instructions. The ALS defined in the revised engine TLM
also adds RRD Model RB211-524G2-T-19, RB211-524G3-T-19, RB211-524H-T-
36, and RB211-524H2-T-19 engines to the list of affected engines.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1410.
In the NPRM, the FAA proposed to require revising the existing
approved engine maintenance or inspection program, as applicable, to
incorporate new and more restrictive airworthiness limitations, which
are specified in EASA AD 2022-0232 described previously, except for any
differences identified as exceptions in the regulatory text of this AD
and as discussed under ``Differences Between this AD and the MCAI.''
Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International (ALPA). ALPA 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 2022-0232, which specifies instructions
for
[[Page 76103]]
accomplishing the actions specified in the applicable 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 TLM.
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
Where paragraph (3) of EASA AD 2022-0232 specifies revising the
approved Aircraft Maintenance Programme within 12 months after the
effective date of EASA AD 2022-0232, this AD requires revising the ALS
of the existing approved engine maintenance or inspection program, as
applicable, within 90 days after the effective date of this AD.
Costs of Compliance
The FAA estimates that this AD affects 22 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:

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

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
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.
