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 all RRD Model RB211–535C–37 

engines. The NPRM published in the 

Federal Register on June 13, 2023 (88 

FR 38409). The NPRM was prompted by 

AD 2022–0236, dated December 1, 2022 

(EASA AD 2022–0236) (also 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 

RB211–535C–37 engines, which is 

approved by EASA, is defined and 

published in TLM T–211(535)–5RR, and 

that these airworthiness limitations 

have been identified as mandatory for 

continued airworthiness. The MCAI also 

states that the manufacturer published a 

revised engine TLM to introduce new or 

more restrictive instructions and 

associated thresholds and intervals for 

life-limited parts. 

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 instructions and associated 

thresholds and intervals for life-limited 

parts, which are specified in EASA AD 

2022–0236, described previously, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1210. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

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, 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– 

0236, which specifies procedures for 

operators to revise the ALS of their 

existing approved engine maintenance 

or inspection program to incorporate 

new or more restrictive instructions and 

associated thresholds and intervals for 

life-limited parts described in the 

revised engine TLM, as applicable to 

each engine model. EASA AD 2022– 

0236 also describes actions for replacing 

life-limited parts, performing 

maintenance tasks, and performing 

corrective actions for any finding of 

discrepancy as referenced in the engine 

TLM. 

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 2 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 

Revise ALS of the operator’s existing approved engine maintenance or inspection program.1 work-hour × $85 per hour 

= $85.

$0 $85 $170 

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 

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.
