1A30, LEAP–1A32, LEAP–1A33, LEAP– 

1A33B2, and LEAP–1A35A model 

turbofan engines. This AD was 

prompted by the detection of meltrelated freckles in the billet, which may 

reduce the life of certain compressor 

rotor stages 6–10 spools, high pressure 

turbine (HPT) rotor interstage seals, HPT 

rotor stage 2 disks, low pressure turbine 

(LPT) stage 1 disks, LPT stage 2 disks, 

LPT stage 3 disks, and LPT stage 4 

disks. This AD requires revising the 

airworthiness limitations section (ALS) 

of the applicable CFM LEAP–1A Engine 

Shop Manual (ESM) and the operator’s 

existing approved continuous 

airworthiness maintenance program 

(CAMP) to incorporate reduced life 

limits for these parts. This AD also 

requires the removal of certain LPT 

stage 4 disks identified by serial number 

(S/N) prior to their new life limits. The 

FAA is issuing this AD to address the 

unsafe condition on these products.

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 CFM LEAP–1A23, LEAP– 

1A24, LEAP–1A24E1, LEAP–1A26, 

LEAP–1A26CJ, LEAP–1A26E1, LEAP– 

1A29, LEAP–1A29CJ, LEAP–1A30, 

LEAP–1A32, LEAP–1A33, LEAP– 

1A33B2, and LEAP–1A35A model 

turbofan engines. The NPRM published 

in the Federal Register on January 18, 

2022 (87 FR 2563). The NPRM was 

prompted by the manufacturer’s 

detection of melt-related freckles in the 

billet, which may reduce the life of 

certain compressor rotor stages 6–10 

spools, HPT rotor interstage seals, HPT 

rotor stage 2 disks, LPT stage 1 disks, 

LPT stage 2 disks, LPT stage 3 disks, 

and LPT stage 4 disks (life-limited parts 

(LLPs)). Through the manufacturer’s 

investigation, it was determined that 

these LLPs may have subsurface 

anomalies that developed during the 

manufacturing process, resulting in a 

lower life capability. In the NPRM, the 

FAA proposed to require revising the 

ALS of the CFM LEAP–1A ESM, as 

applicable to each affected engine 

model, and the operator’s existing 

approved CAMP to incorporate reduced 

life limits for certain LLPs. In the 

NPRM, the FAA also proposed to 

require operators to remove certain LPT 

stage 4 disks, identified by S/N, before 

reaching their new life limits. The LPT 

stage 4 disks, identified by S/N in 

Figure 1 to paragraph (g)(2) of the 

NPRM, were discovered by the 

manufacturer after publication of the 

ALS revision. 

After the NPRM was issued, CFM 

revised its service information by 

including additional part numbers for 

newly manufactured parts that did not 

exist prior to NPRM publication. 

Accordingly, the FAA has revised 

paragraph (g)(1)(iii) of this AD to require 

operators to update the ALS of the 

applicable CFM LEAP–1A ESM and the 

operator’s existing approved CAMP to 

include CFM Low Pressure Turbine 

Rotor Life Limits LEAP 1A–05–11–04– 

01A–0B1B–C, Issue 010–00, dated 

February 15, 2022, instead of CFM Low 

Pressure Turbine Rotor Life Limits 

LEAP 1A–05–11–04–01A–0B1B–C, 

Issue 009–00, dated June 1, 2021. 

The FAA has also added a credit for 

previous actions paragraph to this AD, 

providing credit to operators that 

incorporated CFM Low Pressure 

Turbine Rotor Life Limits LEAP 1A–05– 

11–04–01A–0B1B–C, Issue 009–00, 

dated June 1, 2021, into the ALS of the 

applicable ESM and the operator’s 

existing approved CAMP prior to the 

effective date of this AD. 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two commenters. The commenters were 

American Airlines (AA) and Air Line 

Pilot Association, International (ALPA). 

The following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request To Include Future Revisions to 

ESM 

AA requested that the FAA add ‘‘. . . 

or later’’ to the following ALS references 

in paragraph (g) of this AD to allow for 

the use of future revisions; 

(i) CFM High Pressure Compressor 

Rotor Life Limits LEAP 1A–05–11–02– 

01A–0B1B–C, Issue 010–00, dated 

September 15, 2021, or later; 

(ii) CFM High Pressure Turbine Rotor 

Life Limits LEAP 1A–05–11–03–01A– 

0B1B–C, Issue 007–00, dated September 

15, 2021, or later; and 

(iii) CFM Low Pressure Turbine Rotor 

Life Limits LEAP 1A–05–11–04–01A– 

0B1B–C, Issue 009–00, dated June 1, 

2021, or later. 

AA stated that they are currently 

using Issues 7, 9, and 10 of the 

referenced service information and their 

ALS and CAMP are already in 

compliance with this AD. AA also 

stated that CFM continues to update the 

referenced service information and 

Issues 7, 9, and 10 will be further 

revised. As a result, the requirements of 

this AD will cause AA to use outdated 

service information. 

The FAA disagrees with adding ‘‘or 

later’’ when referencing the service 

information in paragraph (g) of this AD. 

Future revisions of the service 

information have not yet been published 

by the manufacturer or reviewed by the 

FAA. A request for an alternative 

method of compliance can be submitted 

to the FAA if future revisions of the 

service information referenced in 

paragraph (g) of this AD are published. 

Additionally, if future revisions of the 

service information are published by the 

manufacturer and approved by the FAA, 

the FAA may consider further 

rulemaking. 

Request To Add Credit for Previous 

Actions 

AA requested that the FAA add a new 

paragraph (h)(3) to this AD to allow 

credit for previous actions associated 

with the required actions proposed in 

paragraph (g)(1)(iii) of the NPRM, 

similar to the credit paragraphs 

proposed in (h)(1) and (h)(2) of the 

NPRM. AA requested that the new 

paragraph (h)(3) provide credit to 

operators if CFM Low Pressure Turbine 

Rotor Life Limits LEAP 1A–05–11–04– 

01A–0B1B–C, Issue 008–00 was 

incorporated into the ALS of the 

applicable ESM and the operator’s 

existing approved CAMP prior to the 

effective date of this AD. 

The FAA notes that CFM Low 

Pressure Turbine Rotor Life Limits 

LEAP 1A–05–11–04–01A–0B1B–C, 

Issue 009–00, dated June 1, 2021, was 

the first issue of this service information 

to include the reduced life limits for 

that module as a result of the 

investigation into melt-related freckles 

in the billet. Issue 008–00 and earlier 

issues do not include the reduced life 

limits so the FAA will not provide 

credit for issues released prior to Issue 

009–00. Since the FAA issued the 

NPRM, the manufacturer published 

CFM Low Pressure Turbine Rotor Life 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 87, No. 99 / Monday, May 23, 2022 / Rules and Regulations 31121 

Limits LEAP 1A–05–11–04–01A–0B1B– 

C, Issue 010–00, dated February 15, 

2022. As a result, the FAA has added 

paragraph (h)(3) to this AD, providing 

credit for actions required by paragraph 

(g)(1)(iii) of this AD if CFM Low 

Pressure Turbine Rotor Life Limits 

LEAP 1A–05–11–04–01A–0B1B–C, 

Issue 009–00, dated June 1, 2021, was 

incorporated into the ALS of the 

applicable ESM and the operator’s 

existing approved CAMP prior to the 

effective date of this AD. 

Support for the AD 

ALPA expressed support for the AD 

as written. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, 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 and any other changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator.

Costs of Compliance 

The FAA estimates that this AD 

affects 256 engines installed on 

airplanes of U.S. registry. The FAA 

estimates that 256 engines installed on 

airplanes of U.S. registry require 

revising the ALS of the CFM LEAP–1A 

ESM and the operator’s existing 

approved CAMP. 

The FAA estimates that zero airplanes 

of U.S. registry require replacement of 

the LPT stage 4 disk. 

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 Engine Manual and the operator’s existing approved CAMP.1 work-hour × $85 per hour = $85 ................. $0 $85 $21,760

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

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2021–13– 

06, which applied to certain Airbus SAS 

Model A350–941 and –1041 airplanes. 

AD 2021–13–06 required revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. Since the FAA issued AD 

2021–13–06, the FAA has determined 

that new or more restrictive 

airworthiness limitations are necessary. 

This AD continues to require the actions 

in AD 2021–13–06 and requires revising 

the existing maintenance or inspection 

program, as applicable, to incorporate 

additional new or more restrictive 

airworthiness limitations, 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 June 21, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of June 21, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0208, 

dated September 15, 2021 (EASA AD 

2021–0208) (also referred to as the 

MCAI), to correct an unsafe condition 

for all Airbus SAS Model A350–941 and 

–1041 airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2021–13–06, 

Amendment 39–21611 (86 FR 40934, 

July 30, 2021) (AD 2021–13–06). AD 

2021–13–06 applied to certain Airbus 

SAS Model A350–941 and –1041 

airplanes. The NPRM published in the 

Federal Register on February 9, 2022 

(87 FR 7397). The NPRM was prompted 

by a determination that new or more 

restrictive airworthiness limitations are 

necessary. The NPRM proposed to 

continue to require the actions in AD 

2021–13–06 and require revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

additional new or more restrictive 

airworthiness limitations, as specified 

in EASA AD 2021–0208. 

The FAA is issuing this AD to address 

hazardous or catastrophic airplane 

system failures. See the MCAI for 

additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received a comment from 

the Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comment received, and 

determined that air safety requires 

adopting this AD as proposed. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0208 describes new 

or more restrictive airworthiness 

limitations for airplane structures and 

safe life limits.

Register approved for incorporation by 

reference as of September 3, 2021 (86 FR 

40934, July 30, 2021).
