SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0017, dated January 30, 2020, 
to correct an unsafe condition for all serial-numbered Wytw[oacute]rnia 
Sprz[eogon]tu Komunikacyjnego (WSK) ``PZL-[Sacute]widnik'' 
Sp[oacute][lstrok]ka Akcyjna (S.A.) Model PZL W-3A helicopters with a 
Collins Aerospace (formerly Goodrich) electric hoist assembly (hoist) 
part number (P/N) 76378-500 having stainless steel cable P/N 712952 
installed. EASA advises that occurrences were reported of cables found 
worn out; the damage consisted of reduction of the cable diameter near 
the swaged terminal. EASA states that subsequent investigation 
identified that the extensive cable wear was possibly caused by 
flickering movement of the hook assembly in the stowage position during 
flights. EASA further states that this condition, if not detected and 
corrected, could lead to reduction of the cable strength, possibly 
resulting in an in-flight loss of the hoist load, injury to persons, or 
damage to and reduced control of the helicopter.
    Accordingly, EASA AD 2020-0017 requires repetitive inspections of 
the cable to detect cable condition and diameter restriction and based 
on those inspection results, either replacing parts or additional 
maintenance actions and reporting non-compliant inspection results to 
Collins Aerospace. For helicopters that do not have the affected hoist 
installed, EASA AD 2020-0017 allows installing an affected hoist 
provided that it is new (never previously installed), overhauled (never 
installed after overhaul), or has passed an inspection (no defect 
found, or defects corrected), less than 25 flight hours before 
installation, in accordance with the instructions of the service 
information.

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 of the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all information provided by EASA and determining the unsafe 
condition exists and is likely to exist or develop on other helicopters 
of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Goodrich Actuation Systems Alert Service Bulletin 
76378-500-25-P01, Revision 0, dated December 3, 2019 (ASB 76378-500-25-
P01). ASB 76378-500-25-P01 specifies procedures to visually inspect

[[Page 21918]]

the cable near the swaged terminal for cable diameter restriction, the 
hook assembly stowage force, and the hook assembly stowage at the up 
limit. ASB 76378-500-25-P01 also specifies corrective action and 
reporting certain data if the cable is not compliant due to cable 
diameter restriction and the results of the hook assembly stowage force 
inspection.
    ASB 76378-500-25-P01 is an attachment to WYTW[Oacute]RNIA 
SPRZ[Eogon]TU KOMUNIKACYJNEGO ``PZL-[Sacute]widnik'' Sp[oacute]lka 
Akcyjna Alert Service Bulletin No. ASB-37-19-309, dated January 28, 
2020 (ASB-37-19-309). ASB 76378-500-25-P01 is incorporated by reference 
in this AD. ASB-37-19-309 is not incorporated by reference in this AD.
    This service information 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 also reviewed ASB-37-19-309. ASB-37-19-309 specifies 
accomplishing repetitive visual inspections of the cable near the 
swaged terminal for cable diameter restriction and a one-time 
inspection of the hook assembly stowage force. ASB-37-19-309 also 
provides a reminder to accomplish the hook assembly stowage procedure 
after each individual hoisting operation performed in flight or on the 
ground.

AD Requirements

    This AD requires within 25 hours time-in-service accumulated by the 
hoist (hoist hours) after the effective date of this AD, and thereafter 
at intervals not to exceed 25 hoist hours for all PZL Model W-3A 
helicopters with hoist P/N 76378-500 having stainless steel cable P/N 
712952 installed, inspecting the cable for wear and damage, inspecting 
the measurement of the diameter of the cable, and removing the cable 
from service or replacing the cable with an airworthy part before 
further hoist operation if certain criteria is met. This AD also 
requires following certain reinstallation steps and reporting certain 
information. Finally, this AD prohibits installing an affected hoist or 
cable unless they meet the conditions as required by this AD.

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.) (5 U.S.C.) 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 seeking comment 
prior to the rulemaking. Further, section 553(d) of the APA authorizes 
agencies to make rules effective in less than thirty days, upon a 
finding of good cause.
    There are no helicopters with this type certificate on the U.S. 
Registry. Accordingly, notice and opportunity for prior public comment 
are unnecessary pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
reasons stated above, 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.

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-2021-0299 and Project Identifier 
MCAI-2020-00253-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, Aerospace Engineer, General Aviation & Rotorcraft Section, 
International Validation Branch, FAA, 10101 Hillwood Pkwy., Fort Worth, 
TX 76177; telephone 817-222-5110; email [email protected]. Any 
commentary that the FAA receives which 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

    There are no costs of compliance associated with this AD because 
there are no helicopters with this type certificate on the U.S. 
Registry.

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 1 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

[[Page 21919]]

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

    The FAA determined that 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.
