Airworthiness Directives; PZL Swidnik 

S.A. Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

PZL Swidnik S.A. Model PZL W–3A 

helicopters. This AD requires visually 

inspecting the bonding on a certain partnumbered fairing installed on a certain 

part-numbered vibration absorber, 

improving the bonding if necessary, 

using improved installation procedures 

to secure the fairing to the vibration 

absorber, and removing certain parts 

from service. This AD also prohibits 

installing the affected part unless it is 

inspected and installed per the AD 

requirements. This AD was prompted by 

a report of a broken bolt securing the 

fairing to the vibration absorber that 

resulted from an incorrect torque value 

for the nut used to secure the fairing to 

the vibration absorber. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD becomes effective 

August 26, 2021. The FAA must receive 

comments on this AD by October 12, 

2021.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2020–0038, 

dated February 27, 2020 (EASA AD 

2020–0038), to correct an unsafe 

condition for all serial-numbered 

Wytwo ́rnia Sprze ̨tu Komunikacyjnego 

(WSK) ‘‘PZL-S ́ widnik’’ Spo ́5ka Akcyjna 

(S.A.) Model PZL W–3A and PZL W– 

3AS helicopters. EASA AD 2020–0038 

advises that a bolt part number (P/N) 

3003A–6–16–3 was found broken on 

fairing P/N 30.23.015.00.03 installed on 

vibration absorber P/N 30.23.000.00.04. 

EASA states further investigations 

identified that the maintenance 

instructions detailing how to secure the 

affected parts did not include the torque 

value information to tighten the 

castellated nut P/N 3336A–6. EASA 

further states that this condition, if not 

corrected, could lead to detachment of 

the affected part from the helicopter and 

its subsequent contact with helicopter 

stationary or rotary parts, possibly 

resulting in damage to, and consequent 

reduced control of, the helicopter. 

Accordingly, EASA AD 2020–0038 

requires the use of improved installation 

instructions to secure the affected 

fairing to the vibration absorber. 

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 AD. The FAA is issuing 

this AD after evaluating all known 

relevant information and determining 

that the unsafe condition described 

previously is likely to exist or develop 

on other helicopters of the same type 

design. 

Related Service Information 

The FAA reviewed WYTWO ́ RNIA 

SPRZE ̨ TU KOMUNIKACYJNEGO ‘‘PZLS ́ widnik’’ Spo ́5ka Akcyjna Alert Service 

Bulletin No. ASB–37–19–307, dated 

January 27, 2020. This service 

information specifies checking 

(inspecting) the bonding between the 

fairing and vibration absorber star for 

any nonconformity and improving the 

bonding if necessary. This service 

information also specifies the specific 

torque to be used to tighten the 

castellated nuts during installation of 

the fairing onto the vibration absorber. 

AD Requirements 

This AD requires, within 300 hours 

time-in-service after the effective date of 

this AD, removing from service each 

bolt P/N 3003A–6–16–3, washer P/N 

3402A–1, and castellated nut P/N 

3336A–6 that secure fairing P/N 

30.23.015.00.03 to vibration absorber P/ 

N 30.23.000.00.04, and inspecting the 

bonding between the fairing and 

vibration absorber to determine if there 

is any anodic coating. If there is anodic 

coating, this AD requires polishing the 


jbell on DSKJLSW7X2PROD with RULES
43910 Federal Register / Vol. 86, No. 152 / Wednesday, August 11, 2021 / Rules and Regulations 

surface of the fairing where the washers 

make contact, burnishing the affected 

area using abrasive paper, and washing 

the surface with a cleaning solution. 

This AD then requires installing a new 

bolt, new washer, and new nut to 

connect the fairing to the vibration 

absorber. Additionally, this AD requires 

using a specified torque, torqueing each 

nut, locking each nut with a cotter pin, 

and if the specified torque cannot be 

accomplished, removing the washer and 

nut from service, installing airworthy 

parts, and reapplying torque. Finally, 

this AD prohibits installing an affected 

fairing or vibration absorber unless they 

meet the inspection and installation 

requirements of this AD. 

Differences Between This AD and the 

EASA AD 

EASA AD 2020–0038 applies to all 

serial-numbered Model PZL W–3A and 

PZL W–3AS helicopters, whereas this 

AD only applies to Model PZL W–3A 

helicopters with fairing part number (P/ 

N) 30.23.015.00.03 installed on 

vibration absorber P/N 30.23.000.00.04 

installed. This AD does not apply to 

Model PZL W–3AS helicopters because 

that model is not FAA type-certificated. 

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. 

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 foregoing reasons, 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–2021–0652; 

Project Identifier MCAI–2020–00271–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 

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 prior 

notice and comment, RFA analysis is 

not required. 

Costs of Compliance 

There are no costs of compliance with 

this AD because there are no helicopters 

with this type certificate on the U.S. 

Registry. 

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.
