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) 2021–25– 

04 for certain Rolls-Royce Deutschland 

Ltd & Co KG (RRD) Model Trent 1000 

engines. AD 2021–25–04 required 

operators to revise the airworthiness 

limitations section (ALS) of their 

existing approved continuous 

airworthiness maintenance program by 

incorporating the revised tasks of the 

applicable time limits manual (TLM) for 

each affected model turbofan engine. 

Since the FAA issued AD 2021–05–04, 

the manufacturer revised the TLM to 

introduce new or more restrictive tasks 

and limitations and associated 

thresholds and intervals for life-limited 

parts, which prompted this AD. This AD 

requires 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, 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 January 31, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 31, 2024.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2021–25–04, 

Amendment 39–21847 (86 FR 71129, 

December 15, 2021) (AD 2021–25–04). 

AD 2021–25–04 applied to RRD Model 

Trent 1000–AE3, Trent 1000–CE3, Trent 

1000–D3, Trent 1000–G3, Trent 1000– 

H3, Trent 1000–J3, Trent 1000–K3, 

Trent 1000–L3, Trent 1000–M3, Trent 

1000–N3, Trent 1000–P3, Trent 1000– 

Q3, and Trent 1000–R3 engines. AD 

2021–25–04, which was prompted by 

EASA AD 2020–0243, dated November 

5, 2020 (EASA AD 2020–0243), 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. The FAA issued AD 2021–25–04 

to prevent the failure of critical rotating 

parts, which could result in failure of 

one or more engines, loss of thrust 

control, and loss of the airplane. 

Since the FAA issued AD 2021–25– 

04, EASA superseded EASA AD 2020– 

0243 with EASA AD 2022–0247, dated 

December 14, 2022 (EASA AD 2022– 

0247) and then superseded EASA AD 

2022–0247 with EASA AD 2023–0115, 

dated June 7, 2023 (EASA AD 2023– 

0115). 

The NPRM published in the Federal 

Register on September 18, 2023 (88 FR 

63885); corrected on September 27, 

2023 (88 FR 66316). The NPRM was 

prompted by EASA AD 2023–0115 (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. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1889. 

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 tasks and limitations and 

associated thresholds and intervals for 

life-limited parts. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

The Boeing Company (Boeing). Boeing 

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 2023– 

0115, which specifies procedures for 

operators to revise 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 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 

2023–0115 specifies revising the 

approved Aircraft Maintenance 

Programme within 12 months after the 

effective date of EASA AD 2023–0115, 

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. 

This AD does not require compliance 

with paragraphs (1), (2), (4), and (5) of 

EASA AD 2023–0115. 

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: 

ESTIMATED COSTS

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.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority, as it amends 

Class E airspace in Statesboro, GA. 

History 

The FAA published a notice of 

proposed rulemaking for Docket No. 

FAA 2023–2051 in the Federal Register 

on November 2, 2023 (88 FR 75242), 

proposing to amend Class E airspace 

extending upward from 700 feet above 

the surface for Statesboro-Bulloch 

County Airport, Statesboro, GA. 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. 

Incorporation by Reference 

Class E airspace designations are 

published in Paragraph 6005 of FAA 

Order JO 7400.11, Airspace 

Designations and Reporting Points, 

incorporated by reference in 14 CFR 

71.1 annually. This document amends 

the current version of that order, FAA 

Order JO 7400.11H, dated August 11, 

2023, and effective September 15, 2023. 

FAA Order JO 7400.11H is publicly 

available as listed in the ADDRESSES

section of this document. These 

amendments will be published in the 

next FAA Order JO 7400.11 update. 

FAA Order JO 7400.11H lists Class A, 

B, C, D, and E airspace areas, air traffic 

service routes, and reporting points. 

The Rule 

This action amends 14 CFR part 71 by 

amending Class E airspace extending 

upward from 700 feet above the surface 

for Statesboro-Bulloch County Airport, 

Statesboro, GA, by increasing the Class 

E airspace extending upward from 700 

feet above the surface to 7.2-miles 

(previously 6.5-miles), to support a 

revised RNAV approach procedure. In 

addition, this action updates the airport 

name (formerly Statesboro Municipal 

Airport) and the geographic coordinates 

to coincide with the FAA’s database. 

Controlled airspace is necessary for the
