Federal Register Abstract

We are adopting a new airworthiness directive (AD) for the PZL Swidnik S.A. (PZL) Model PZL W-3A helicopter with a certain generator air outlet collector (collector) installed. This AD requires modifying the generator air outlet collector attachments (collector attachments). This AD is prompted by an incident where cyclic control stick movement was restricted due to rotation of a loose collector, resulting in locking of the longitudinal control system hydraulic actuator fork end. These actions are intended to prevent rotation of the collector, which could lead to restricted cyclic control stick movement, and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments prior to it becoming effective. However, we 
invite you to participate in this rulemaking by submitting written 
comments, data, or views. We also invite 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. We will file in the docket all comments that 
we receive, as well as a report summarizing each substantive public 
contact with FAA personnel concerning this rulemaking during the 
comment period. We will consider all the comments we receive and may 
conduct additional rulemaking based on those comments.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2010-0017, dated January 29, 2010, to correct an unsafe condition 
for the PZL Model PZL W-3A helicopter with a generator air outlet 
collector, part number (P/N) GT40PCz8B, installed. EASA advises there 
was a report of an in-flight incident where cyclic control stick 
movement was restricted. Post-flight investigation revealed that this 
incident was caused by the rotation of a loose collector, resulting in 
the locking of the longitudinal control system hydraulic actuator fork 
end. This condition, if not detected, could lead to restricted cyclic 
control stick movement, and subsequent loss of control of the 
helicopter.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Poland and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Poland, EASA, their technical 
representative, has notified us of the unsafe condition described in 
their AD. We are issuing this AD because we evaluated all information 
provided by EASA and determined the unsafe condition exists and is 
likely to exist or develop on other helicopters of this same type 
design.
    There are no helicopters of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these helicopters are 
placed on the U.S. Registry in the future.

Related Service Information

    PZL has issued Service Bulletin No. BS-37-09-230, dated October 13, 
2009 (SB), which specifies modifying the collector attachments to 
prevent collector rotation. The SB specifies installing a cable and 
reinforcing the welded clamping rings' connections with additional 
rivets. EASA classified this SB as mandatory and issued AD No. 2010-
0017 to ensure the continued airworthiness of these helicopters.

AD Requirements

    This AD requires modifying the collector attachments with a 
protective cable and additional riveting as described in Section II of 
the manufacturer's service bulletin.

Differences between this AD and the EASA AD

    The EASA AD requires compliance within one month after the 
effective date of their AD, while this AD requires compliance within 
100 hours time-in-service.

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.

FAA's Justification and Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are unnecessary because there are 
none of these products on the U.S. Registry and that good cause exists 
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.
    We are 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

    We 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;

[[Page 41899]]

    2. Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
