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. 2018-0092-E, dated April 20, 
2018, 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 with a serial number up to 3X.10.12 inclusive. EASA advises 
of an occurrence reported of finding cracks on the Main XMSN case 
housing. EASA further advises investigation results indicate the 
cracking mode has features of fatigue deterioration, but the root cause 
has not been determined. Accordingly, the EASA AD requires repetitive 
inspections of the Main XMSN case and, based on the inspection results, 
replacing certain parts. EASA also requires reporting the inspection 
results to PZL-[Sacute]widnik S.A. EASA considers its AD an interim 
action and further AD action may follow. EASA states this condition, if 
not detected and corrected, could lead to structural failure and loss 
of load carrying capabilities of the Main XSMN, 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

    The FAA reviewed WYTW[Oacute]RNIA SPRZ[Eogon]TU KOMUNIKACYJNEGO 
``PZL-[Sacute]widnik'' Sp[oacute]lka Akcyjna Mandatory Bulletin No. BO-
37-18-294, dated April 12, 2018, which specifies using a light source 
and mirror to inspect the Main XSMN case for indications of possible 
cracks, such as paint coat chipping, surface scratches, and oil leaks. 
This service information also specifies reporting certain information 
to PZL-[Sacute]widnik S.A., performing more in-depth inspections by 
performing a ground run test and checking for chalk mark discoloration, 
and if a crack exists, replacing the Main XSMN case before further 
flight.
    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

    The AD requires within 5 hours time-in-service (TIS), and 
thereafter at intervals not to exceed 25 hours TIS, for all PZL Model 
PZL W-3A helicopters serial number up to and including 3X.10.12 with 
Main XMSN case part number (P/N) 64.21.0105 or P/N 64.22.0161 installed 
on WR-3 Main XMSN P/N 64.21.3000 or P/N 64.21.4000, visually inspecting 
the Main XMSN case for a crack, a surface scratch, any paint coat 
chipping, and any oil leak and removing the Main XMSN from service 
before further flight if any of those conditions exist.

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-[Sacute]widnik S.A., 
whereas this AD does not.

Interim Action

    The FAA considers this proposed AD to be an interim action. If 
final action is later identified, the FAA might consider further 
rulemaking then.

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.

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, the FAA finds good cause that 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 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 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.
