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) 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 onetime 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 regulations.gov 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.

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: 

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: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Austro Engine GmbH 

Model E4 and E4P engines. The NPRM 

published in the Federal Register on 

July 14, 2023 (88 FR 45118). The NPRM 

was prompted by European Union 

Aviation Safety Agency (EASA) AD 

2022–0240R1, dated December 15, 2022 

(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 

a manufacturer investigation into 

reports of piston failures determined 

that certain batches of pistons were 

manufactured with a dimensional 

deviation in the piston pin bore and in 

the piston diameter, which could cause 

piston failure, with consequent loss of 

oil, loss of engine power, and reduced 

control of the airplane. To address the 

unsafe condition, EASA issued EASA 

AD 2022–0240, dated December 6, 2022 

(EASA AD 2022–0240), to specify 

repetitive oil analyses and replacement 

of the pistons, piston rings, con-rods 

assembly, and crankcase, or as an 

alternative, replacement of the engine 

core. EASA AD 2022–0240 also 

prohibited release to service of an 

airplane until receipt of the results for 

each oil analysis. 

Since EASA AD 2022–0240 was 

issued, the manufacturer determined 

that aluminum levels outside of the 

acceptable limits would be found during 

the first oil analysis, and are unlikely to 

be found during subsequent oil 

analyses. As a result, EASA revised 


ddrumheller on DSK120RN23PROD with RULES1
