This service information also specifies reporting certain information to PZL and Pratt & Whitney Rzeszo´w S.A., removing the engine for more in-depth inspection of the bolts for signs of rubbing and deformation, inspecting the bolts for proper torque, removing the input drive quill seals, and inspecting the graphite seal assembly. 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. Discussion AD Requirements EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2018– 0238, dated November 6, 2018 (EASA AD 2018–0238), to correct an unsafe condition for Wytwo´rnia Sprze˛tu Komunikacyjnego ‘‘PZL-S´widnik’’ Spo´5ka Akcyjna (WSK ‘‘PZL-S´WIDNIK’’ S.A.) Model PZL W–3A and PZL W– 3AS helicopters. EASA advises of occurrences of improperly locked bolts, which secure the input quill cover and graphite seal assembly of the WR–3 MGB. The bolts are locked in place through the use of locking tabs on the washer part number (P/N) 89.06.0387. According to EASA, a subsequent investigation determined that the root cause of this event was improper assembly of the MGB during manufacturing or overhaul. EASA stated this condition could lead to disconnection of the engines to the MGB This AD requires, within 25 hours time-in-service, for all PZL Model PZL W–3A helicopters that have a WR–3 MGB serial number up to and including 316463007M installed, inspecting each bolt P/N 89.00.0049 for proper locking using a fiberscope. Depending on the inspection outcome, this AD requires removing the engine and inspecting each bolt head for signs of rubbing and deformation, inspecting each bolt for proper torque, removing the left-hand and right-hand input drive quill seals, and inspecting each graphite seal assembly. This AD requires removing from service any bolt with signs of rubbing or deformation on its bolt head. If necessary, this AD requires replacing the graphite seal assembly or removing it from service. This AD also prohibits installing affected MGBs that have not been inspected for improperly locked bolts.

The EASA AD requires reporting certain information to PZL and Pratt & Whitney Rzeszo´w S.A., whereas this AD does not. 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 with this AD because there are no helicopters of this type certificate on the U.S. Registry. jbell on DSKJLSW7X2PROD with RULES FAA’s Justification and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (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. There are no helicopters with this type certificate on the U.S. Registry. Therefore, 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. 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 VerDate Sep<11>2014 16:11 Apr 17, 2020 Jkt 250001 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 helicopters identified in this rulemaking action. (c) Effective Date This AD becomes effective May 5, 2020. Regulatory Findings (e) Required Actions (1) Within 25 hours time-in-service (TIS), inspect each bolt to determine if it is properly locked with the washer by following Chapter II, Inspection Procedure, paragraphs ´ RNIA SPRZE˛TU 3.1.a) and 3.1.b) of WYTWO KOMUNIKACYJNEGO ‘‘PZL-S´widnik’’ Spo´lka Akcyjna Mandatory Bulletin No. BO– 37–18–289, dated October 23, 2018 (MB BO– 37–18–289). If any bolt is not properly locked, before further flight: (i) Remove the engine to visually inspect the bolt head for any sign of rubbing and deformation. (ii) If there is no sign of rubbing or deformation, loosen the bolt and tighten to the correct torque value of 2.5–3.0 Nm. Lock the bolt by folding tabs of the washer up to the side surfaces of the bolt head. Photo 4 of MB BO–37–18–289 shows an example of a properly locked bolt. (iii) If there is any sign of rubbing or deformation; (A) Remove from service the bolt.

(2) If there is any spalling or chipping in surface area ‘‘E’’ that is equal to or less than an area of 1.5 mm2 and a depth of 1 mm, or any scratch or dent in surface areas ‘‘A’’ or ‘‘B’’ or seizing in surface area ‘‘C’’ that is acceptable after blending material flashes, before further flight, replace the graphite seal assembly. (3) If there is any crack, damage, or surface deformation on surface ‘‘D’’, cracked graphite 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 above, 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; 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 PZL 
Swidnik S.A. (PZL) Model PZL W-3A helicopters. This AD requires 
inspecting the main gearbox (MGB) bolts and washers to determine if 
they are properly locked and, depending on the inspection outcome, 
removing the engine, removing certain bolts from

[[Page 21755]]

service, and performing more in-depth inspections; and depending on the 
outcome of those inspections, replacing the graphite seal assembly or 
removing it from service. Finally, this AD prohibits installing any 
affected MGB on a helicopter unless it has met the requirements of this 
AD. This AD was prompted by reports that the bolts securing the input 
quill and graphite seal assembly of the MGB were not properly locked. 
The actions of this AD are intended to address an unsafe condition on 
these products.

DATES: This AD becomes effective May 5, 2020.

SUPPLEMENTARY INFORMATION:

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not provide you with notice and an opportunity 
to provide your comments prior to it becoming effective. However, the 
FAA invites you to participate in this rulemaking by submitting written 
comments, data, or views. The FAA also invites comments relating to the 
economic, environmental, energy, or federalism impacts that resulted 
from adopting this AD. The most helpful comments reference a specific 
portion of the AD, explain the reason for any recommended change, and 
include supporting data. To ensure the docket does not contain 
duplicate comments, commenters should send only one copy of written 
comments, or if comments are filed electronically, commenters should 
submit them only one time. The FAA will file in the docket all comments 
received, as well as a report summarizing each substantive public 
contact with FAA personnel concerning this rulemaking during the 
comment period. The FAA will consider all the comments received and may 
conduct additional rulemaking based on those comments.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2018-0238, dated November 6, 
2018 (EASA AD 2018-0238), to correct an unsafe condition for 
Wytw[oacute]rnia Sprz[eogon]tu Komunikacyjnego ``PZL-[Sacute]widnik'' 
Sp[oacute][lstrok]ka Akcyjna (WSK ``PZL-[Sacute]WIDNIK'' S.A.) Model 
PZL W-3A and PZL W-3AS helicopters.
    EASA advises of occurrences of improperly locked bolts, which 
secure the input quill cover and graphite seal assembly of the WR-3 
MGB. The bolts are locked in place through the use of locking tabs on 
the washer part number (P/N) 89.06.0387. According to EASA, a 
subsequent investigation determined that the root cause of this event 
was improper assembly of the MGB during manufacturing or overhaul. EASA 
stated this condition could lead to disconnection of the engines to the 
MGB mechanical link, possibly resulting in loss of helicopter control.

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

    WYTW[Oacute]RNIA SPRZ[Eogon]TU KOMUNIKACYJNEGO ``PZL-
[Sacute]widnik'' Sp[oacute]lka Akcyjna has issued Mandatory Bulletin 
No. BO-37-18-289, dated October 23, 2018, which specifies using a 
fiberscope to inspect for improperly locked bolts that secure the input 
quill cover and graphite seal assembly of WR-3 MGBs. This service 
information also specifies reporting certain information to PZL and 
Pratt & Whitney Rzesz[oacute]w S.A., removing the engine for more in-
depth inspection of the bolts for signs of rubbing and deformation, 
inspecting the bolts for proper torque, removing the input drive quill 
seals, and inspecting the graphite seal assembly.
    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.

AD Requirements

    This AD requires, within 25 hours time-in-service, for all PZL 
Model PZL W-3A helicopters that have a WR-3 MGB serial number up to and 
including 316463007M installed, inspecting each bolt P/N 89.00.0049 for 
proper locking using a fiberscope. Depending on the inspection outcome, 
this AD requires removing the engine and inspecting each bolt head for 
signs of rubbing and deformation, inspecting each bolt for proper 
torque, removing the left-hand and right-hand input drive quill seals, 
and inspecting each graphite seal assembly. This AD requires removing 
from service any bolt with signs of rubbing or deformation on its bolt 
head. If necessary, this AD requires replacing the graphite seal 
assembly or removing it from service. This AD also prohibits installing 
affected MGBs that have not been inspected for improperly locked bolts.

[[Page 21756]]

Differences Between This AD and the EASA AD

    The EASA AD applies to Model PZL W-3AS helicopters, whereas this AD 
does not because that model is not FAA type-certificated. The EASA AD 
requires reporting certain information to PZL and Pratt & Whitney 
Rzesz[oacute]w S.A., whereas this AD does not.

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

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (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.
    There are no helicopters with this type certificate on the U.S. 
Registry. Therefore, 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.

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 helicopters 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 above, 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.
