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
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.

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: 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.
