Airworthiness Directives; Rolls-Royce

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–15– 

07 for certain Rolls-Royce Deutschland 

Ltd & Co KG (RRD) (type certificate 

previously held by Rolls-Royce plc) 

Model RB211–524G2–19, RB211– 

524G2–T–19, RB211–524G3–19, RB211– 

524G3–T–19, RB211–524H2–19, 

RB211–524H2–T–19, RB211–524H–36, 

and RB211–524H–T–36 engines. AD 

2020–15–07 required replacement of the 

low-pressure turbine (LPT) stage 1 disk 

with part number (P/N) UL37606, 

UL37607, UL37608, UL37722, or 

UL37790, installed. This AD was 

prompted by an updated analysis by the 

engine manufacturer, which indicates 

certain part-numbered and serialnumbered LPT stage 1 disks that have 

undergone rework could fail before the 

current published life limits. This AD 

retains the requirement to replace the 

LPT stage 1 disk and includes 

additional LPT stage 1 disks, 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 

26, 2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of December 26, 2023.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–15–07, 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 222 / Monday, November 20, 2023 / Rules and Regulations 80583 

Amendment 39–21170 (85 FR 43682, 

July 20, 2020) (AD 2020–15–07). AD 

2020–15–07 applied to RRD RB211– 

524G2–19, RB211–524G2–T–19, RB211– 

524G3–19, RB211–524G3–T–19, RB211– 

524H2–19, RB211–524H2–T–19, 

RB211–524H–36, and RB211–524H–T– 

36 model turbofan engines with LPT 

stage 1 disks, P/N UL37606, UL37607, 

UL37608, UL37722, or UL37790, 

installed. AD 2020–15–07 required 

replacement of the LPT stage 1 disk 

before it reaches its new Declared Safe 

Cycle Limit (DSCL) or within 25 flight 

cycles after the effective date of the AD, 

whichever occurs later. The FAA issued 

AD 2020–15–07 to prevent failure of the 

LPT stage 1 disk. 

The NPRM published in the Federal 

Register on July 12, 2023 (88 FR 44235). 

The NPRM was prompted by AD 2022– 

0237, dated December 2, 2022 (EASA 

AD 2022–0237) (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 further investigation by the 

manufacturer identified additional partnumbered LPT stage 1 disks affected by 

the unsafe condition. As a result of this 

finding, RRD published revised service 

information, which includes the 

additional affected LPT stage 1 disk P/ 

Ns. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1399. 

In the NPRM, the FAA proposed to 

include additional LPT stage 1 disks 

and require accomplishing the actions 

specified in the MCAI described 

previously, except for any differences 

identified as exceptions in the 

regulatory text of the NPRM. The FAA 

is issuing this AD to prevent failure of 

the LPT stage 1 disk, which if not 

addressed, could result in uncontained 

release of high-energy debris from the 

engine, in-flight shutdown of the 

engine, damage to the engine, and 

damage to the airplane. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the Air Line Pilots Association, 

International (ALPA) and The Boeing 

Company who 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 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. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2022– 

0237, which specifies procedures for 

replacement of the LPT stage 1 disk and 

reducing the DSCL for LPT stage 1 

disks. 

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 18 engines installed on airplanes 

of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Remove and replace LPT stage 1 disk .......... 120 work-hours × $85 per hour = $10,200 .... $30,000 $40,200 $723,600 

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.
