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 part-
numbered 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 Espa[ntilde]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

[[Page 31117]]

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 type-certificated 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.

[[Page 31118]]

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 
<a href="/cdn-cgi/l/email-protection#dfb4adb6acabb6b1f1bdadbebbb3baa69fb9bebef1b8b0a9"><span class="__cf_email__" data-cfemail="94ffe6fde7e0fdfabaf6e6f5f0f8f1edd4f2f5f5baf3fbe2">[email protected]</span></a>. 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: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
