Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Notice of proposed rulemaking (NPRM).
SUMMARY:
The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211-535C-37 engines. This proposed AD was prompted by the manufacturer revising the existing engine time limits manual (TLM) to introduce new or more restrictive airworthiness limitations and associated thresholds and intervals for life-limited parts. This proposed AD would require 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 instructions and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
DATES:
The FAA must receive comments on this proposed AD by July 28, 2023.

Background
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022-0236, dated December 1, 2022 (EASA AD 2022-0236) (referred to after this as the MCAI), to address an unsafe condition for all RRD Model RB211-535C-37 engines. 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.
You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2023-1210.
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 .
FAA's Determination
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 described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would 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 proposed AD and as discussed under "Differences Between this Proposed AD and the EASA AD."
Differences Between This Proposed AD and the EASA AD
Where paragraph (3) of EASA AD 2022-0236 specifies revising the approved Aircraft Maintenance Programme within 12 months after the effective date of EASA AD 2022-0236, this proposed AD would require 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 proposed AD would not require compliance with paragraphs (1), (2), (4), and (5) of EASA AD 2022-0236.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and CAAs to use this process. As a result, the FAA proposes to incorporate by reference EASA AD 2022-0236 in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022-0236 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to "all required actions and compliance times," compliance with this AD requirement is not limited to the section titled "Required Action(s) and Compliance Time(s)" in EASA AD 2022-0236. Service information required by the EASA AD for compliance will be available at regulations.gov by searching for and locating Docket No. FAA-2023-1210 after the FAA final rule is published. Service information required by the EASA AD for compliance will be available at regulations.gov by searching for and locating Docket No. FAA-2023-1210 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would affect 2 engines installed on airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed AD:
| 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.
[top] The FAA is issuing this rulemaking under the authority described in
Regulatory Findings
The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(1) Is not a "significant regulatory action" under Executive Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
