RIN 2120-AA64
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2009-04-13 for
certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model BR700-715A1-30, BR700715B1-30, and BR700-715C1-30 engines. AD 2009-04-13 required 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
tasks and limitations and associated thresholds and intervals for life-limited parts. AD
2009-04-13 also required removing certain low-pressure compressor (LPC) (fan) disc
assemblies from service and completing the Life Limited Part Tracking Sheet. Since the
FAA issued AD 2009-04-13, the manufacturer has revised the engine time limits manual
(TLM) to introduce new or more restrictive tasks and limitations and associated
thresholds and intervals for life-limited parts. This AD requires revising the ALS of the
existing approved engine maintenance or inspection program, as applicable, to
incorporate new or more restrictive tasks and limitations and associated thresholds and
intervals for life-limited parts. The FAA is issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective [INSERT DATE 35 DAYS AFTER DATE OF

PUBLICATION IN THE FEDERAL REGISTER].
The Director of the Federal Register approved the incorporation by reference of a
certain publication listed in this AD as of [INSERT DATE 35 DAYS AFTER DATE OF
PUBLICATION IN THE FEDERAL REGISTER].

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part
39 to supersede AD 2009-04-13, Amendment 39-15819 (74 FR 7643, February 19, 2009)
(AD 2009-04-13). AD 2009-04-13 applied to RRD Model BR700-715A1-30, BR700715B1-30, and BR700-715C1-30 engines, with an LPC compressor (fan) disc assembly,
part number (P/N) BRH10048 or P/N BRH19253. AD 2009-04-13 required revising the
ALS of the operator's existing approved engine maintenance or inspection program, as
applicable, to incorporate new or more restrictive tasks and limitations and associated
thresholds and intervals for life-limited parts. Additionally, AD 2009-04-13 required
removing LPC compressor (fan) disc assemblies from service that exceed a certain life
limit, removing LPC compressor (fan) disc assemblies from service that do not pass the
Hawaiian Flight Mission check, and completing the Life Limited Part Tracking Sheet.
The FAA issued AD 2009-04-13 to prevent failure of critical rotating parts, which, if not
addressed, could result in uncontained failure of the LPC (fan) disc assembly and damage
to the airplane.
The NPRM was published in the Federal Register on July 6, 2026 (91 FR 40900).
The NPRM was prompted by EASA AD 2025-0086, dated April 16, 2025 (EASA AD
2025-0086) (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 to introduce new or more restrictive tasks
and limitations and associated thresholds and intervals for life-limited parts.
In the NPRM, the FAA proposed to require revising the ALS of the existing
approved engine maintenance or inspection program, as applicable, to incorporate new or
more restrictive tasks and limitations and associated thresholds and intervals for lifelimited parts.

Discussion of Final Airworthiness Directive
Comments
The FAA received comments from two commenters. Commenters included the
Air Line Pilots Association, International and The Boeing Company. All commenters
supported the NPRM without change.
Conclusion
These products have been approved by the civil 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, that authority has notified the
FAA of the unsafe condition described in the MCAI referenced above. The FAA
reviewed the relevant data, considered any 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, this
AD is adopted as proposed in the NPRM. None of the changes will increase the economic
burden on any operator.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed EASA AD 2025-0086, which specifies revising the ALS of
the existing approved engine maintenance or inspection program, as applicable, to
incorporate new or more restrictive tasks and limitations and associated thresholds and
intervals for life-limited parts.
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 the ADDRESSES
section.
Differences Between this AD and the MCAI
Where paragraph (3) of EASA AD 2025-0086 specifies revising the approved
Aircraft Maintenance Programme (AMP) within 12 months after the effective date of

EASA AD 2025-0086, this AD requires revising the ALS of the existing approved engine
maintenance or inspection program, as applicable, within 30 days after the effective date
of this AD.
Costs of Compliance
The FAA estimates that this AD affects 218 engines installed on airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:

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.
List of Subjects in 14 CFR Part 39

The Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA
amends 14 CFR part 39 as follows:

EASA AD 2025-0086.
(3) Where paragraph (3) of EASA AD 2025-0086 specifies “Within 12 months
after the effective date of this AD, revise the approved AMP”, this AD requires replacing
that text with “Within 30 days after the effective date of this AD, revise the airworthiness
limitations section (ALS) of the existing approved engine maintenance or inspection
program, as applicable”.
(4) This AD does not adopt the “Remarks” section of EASA AD 2025-0086.
(i) Provisions for Alternative Actions and Intervals
No alternative actions and associated thresholds and intervals, including life
limits, are allowed for compliance with paragraph (g) of this AD unless they are
approved as specified in the provisions of the “Ref. Publications” section of EASA AD
2025-0086.
