SUPPLEMENTARY INFORMATION: 

Background 

On May 3, 2022, the FAA issued 

Emergency AD 2022–10–51 for Airbus 

Helicopters Model AS350B, AS350B1, 

AS350B2, AS350B3, AS350BA, 

AS350D, AS355E, AS355F, AS355F1, 

AS355F2, AS355N, AS355NP, EC130B4, 

and EC130T2 helicopters; and Airbus 

Helicopters Deutschland GmbH (AHD) 

Model EC135P1, EC135P2, EC135P2+, 

EC135P3, EC135T1, EC135T2, 

EC135T2+, EC135T3, MBB–BK 117 C–2, 

MBB–BK 117 D–2, and MBB–BK 117 D– 

3 helicopters. Emergency AD 2022–10– 

51 requires removing certain partnumbered and serial-numbered flight 

control Flexball cables from service and 

prohibits installing those flight control 

Flexball cables on any helicopter. 

Emergency AD 2022–10–51 also 

requires reporting certain information to 

Airbus Helicopters or AHD, as 

applicable. The FAA sent the emergency 

AD to all known U.S. owners and 

operators of these helicopters. That 

action was prompted by EASA 

Emergency AD 2022–0077–E, dated 

April 29, 2022 (EASA AD 2022–0077– 

E), to correct an unsafe condition for 

Airbus Helicopters (AH), formerly 

Eurocopter, Eurocopter France, 

Aerospatiale, Model AS 350 B, AS 350 

B1, AS 350 B2, AS 350 B3, AS 350 BA, 

AS 350 BB, AS 350 D, AS 355 E, AS 355 

F, AS 355 F1, AS 355 F2, AS 355 N, AS 

355 NP, EC 130 B4, and EC 130 T2 

helicopters, all serial numbers (S/Ns); 

and Airbus Helicopters Deutschland 

GmbH (AHD), formerly Eurocopter 

Deutschland GmbH, Eurocopter Espan ̃ a 

S.A., Model EC 135 T1, EC 135 T2, EC 

135 T2+, EC 135 T3, EC 135 P1, EC 135 

P2, EC 135 P2+, EC 135 P3, EC 635 T1, 

EC 635 T2+, EC 635 T3, EC 635 P2+, EC 

635 P3, MBB–BK 117 D–2, MBB–BK 117 

D–3, MBB–BK 117 D–3m, and MBB–BK 

117 C–2 helicopters, all S/Ns. 

The FAA is issuing this AD to address 

non-conforming flight control Flexball 

cables, which, if not addressed, could 

result in increased friction inside the 

flight control Flexball cables, jamming 

of the flight controls, and subsequent 

loss of control of the helicopter. See 

EASA AD 2022–0077–E for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2022–0077–E requires 

replacing affected flight control Flexball 

cables with a serviceable part and 

prohibits installing an affected flight 

control Flexball cable on any helicopter. 

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 the ADDRESSES section. 

Other Related Service Information 

The FAA reviewed Airbus Helicopters 

Emergency Alert Service Bulletin 

(EASB) AS350 67.00.81, AS355 

67.00.49, and EC130 67A023, which are 

co-published as one document along 

with AS550 67.00.45 (military) and 

AS555 67.00.34 (military), EASB 

EC135–67A–043, EASB EC135H–67A– 

016, EASB MBB–BK117 C–2–67A–032, 

and EASB MBB–BK117 D–2–67A–021, 

each Revision 0 and dated April 29, 

2022. This service information specifies 

procedures for determining if an 

affected Flexball is installed. If an 

affected Flexball is installed, or if it 

cannot be determined if an affected 

Flexball is installed, this service 

information specifies procedures for 

replacing the Flexball, returning the 

removed Flexball to the supplier, and 

completing and emailing a reply form 

sheet to Airbus Helicopters Customer 

Support or Airbus Helicopters Service 

Bulletin Germany, depending on your 

model helicopter. 

FAA’s Determination 

These helicopters have been approved 

by EASA and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the 

European Union, EASA has notified the 

FAA about the unsafe condition 

described in its emergency AD. The 

FAA is issuing this AD after evaluating 

all pertinent information and 

determining that the unsafe condition 

exists and is likely to exist or develop 

on other helicopters of the same type 

designs. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2022– 

0077–E, described previously, as IBRed, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD and except as discussed under 

‘‘Differences Between this AD and the 

EASA AD.’’ 

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 been coordinating 

this process with manufacturers and 

CAAs. As a result, EASA AD 2022– 

0077–E is IBRed in this FAA final rule. 

This AD, therefore, requires compliance 

with EASA AD 2022–0077–E in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

AD. Using common terms that are the 

same as the heading of a particular 

section in EASA AD 2022–0077–E 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 2022–0077–E. 

Service information referenced in EASA 

AD 2022–0077–E for compliance will be 

available at https://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2022–0519 after this final rule is 

published. 

Differences Between This AD and the 

EASA AD 

EASA AD 2022–0077–E applies to 

Airbus Helicopters Model AS 350 BB 

helicopters and Airbus Helicopters 

Deutschland GmbH (AHD) Model EC 

635 T1, EC 635 T2+, EC 635 T3, EC 635 

P2+, EC 635 P3, and MBB–BK 117 D– 

3m helicopters. This AD does not apply 

to those model helicopters because 

those models are not FAA typecertificated and are not included on the 

U.S. type certificate data sheet (TCDS), 

except where the TCDS explains that 

the Model EC635T2+ helicopter having 

serial number 0858 was converted from 

Model EC635T2+ to Model EC135T2+. 

The service information referenced in 

EASA AD 2022–0077–E specifies 

sending removed Flexball cables to the 

supplier; whereas, this AD requires 

removing an affected part from service. 

EASA AD 2022–0077–E specifies that a 

single ferry flight without passengers is 

allowed to a maintenance location 

where the action required by the AD can 

be accomplished; whereas this AD may 

allow a special flight permit or 

continuous authorization flight for a 

single flight, provided that there are no 

passengers onboard and that there is no 

noticeable increase in friction in the 

flight control system. EASA AD 2022– 

0077–E does not require reporting 

information; whereas, this AD does. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

required the immediate adoption of 

Emergency AD 2022–10–51, issued on 

May 3, 2022, to all known U.S. owners 

and operators of these helicopters. The 

FAA found that the risk to the flying 

public justified waiving notice and 

comment prior to adoption of this rule 

because the affected component is part 

of the flight control system and is 

critical to the control of a helicopter. A 

non-conforming flight control Flexball 

cable, if not corrected, could result in 

jamming of the flight controls during 

various operations and phases of flight, 

and over various terrains. Additionally, 

the FAA has no information pertaining 

to how quickly the condition may 

propagate to failure. In light of this, the 

initial actions required by this AD must 

be accomplished before next flight. 

These conditions still exist, therefore, 

notice and opportunity for prior public 

comment are impracticable and contrary 

to the public interest pursuant to 5 

U.S.C. 553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Comments Invited 

The FAA invites you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2022–0519; 

Project Identifier MCAI–2022–00589–R’’ 

at the beginning of your comments. The 

most helpful comments reference a 

specific portion of the final rule, explain 

the reason for any recommended 

change, and include supporting data. 

The FAA will consider all comments 

received by the closing date and may 

amend this final rule because of those 

comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this final rule.

31118 Federal Register / Vol. 87, No. 99 / Monday, May 23, 2022 / Rules and Regulations 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Kristi Bradley, 

Program Manager, COS Program 

Management Section, Operational 

Safety Branch, Compliance & 

Airworthiness Division, FAA, 10101 

Hillwood Pkwy., Fort Worth, TX 76177; 

telephone (817) 222–5110; email 

kristin.bradley@faa.gov. Any 

commentary that the FAA receives that 

is not specifically designated as CBI will 

be placed in the public docket for this 

rulemaking. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because the 

FAA has determined that it has good 

cause to adopt this rule without notice 

and comment, RFA analysis is not 

required. 

Costs of Compliance 

The FAA estimates that this AD 

affects up to 1,785 helicopters of U.S. 

Registry. Labor rates are estimated at 

$85 per work-hour. Based on these 

numbers, the FAA estimates the 

following costs to comply with this AD. 

Replacing a flight control Flexball 

cable takes about 8 work-hours and 

parts cost about $804 to $13,555, 

depending on part number, for an 

estimated cost of $1,484 to $14,235 per 

helicopter and up to $437,780 to 

$4,199,325 for the U.S. fleet (there are 

up to 295 affected flight control Flexball 

cables installed in the U.S. fleet). 

Reporting information takes about 0.5 

work-hour for an estimated cost of $43 

per helicopter and up to $76,755 for the 

U.S. fleet. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to penalty for failure to comply with a 

collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a currently valid 

OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public 

reporting for this collection of 

information is estimated to be 

approximately 0.5 hour per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information. 

All responses to this collection of 

information are mandatory. Send 

comments regarding this burden 

estimate or any other aspect of this 

collection of information, including 

suggestions for reducing this burden, to:

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, I certify 

that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Airworthiness Directives; CFM 

International, S.A. Turbofan Engines 

Editorial Note: Rule document 2022– 

10447 was originally published on pages 

29651 through 29654 in the issue of Monday, 

May 16, 2022. In that publication on page 

29653, in the third column, in paragraph 2(a), 

‘‘June 20, 2022’’ should read ‘‘June 21, 2022’’. 

The corrected document is published here in 

its entirety. 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all CFM 

International, S.A. (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. 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. 

DATES: This AD is effective June 21, 

2022.
