Federal Register Abstract
We are revising an existing airworthiness directive (AD) for Glasflugel Models Standard Libelle-201B, Club Libelle 205, Mosquito, and Kestrel gliders. That AD currently requires actions to address the unsafe condition on these products. This new AD includes clarification that the replacement control rod has an additional drain hole at the rod bottom between the forks and is the acceptable configuration for compliance. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as corrosion damage to the elevator control rod that could lead to failure of the elevator control rod, possibly resulting in loss of control of the glider. We are issuing this AD to require actions to address the unsafe condition on these products.

ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are revising an existing airworthiness directive (AD) for
Glasflugel Models Standard Libelle-201B, Club Libelle 205, Mosquito,
and Kestrel gliders. That AD currently requires actions to address the
unsafe condition on these products. This new AD includes clarification
that the replacement control rod has an additional drain hole at the
rod bottom between the forks and is the acceptable configuration for
compliance. This AD results from mandatory continuing airworthiness
information (MCAI) issued by an aviation authority of another country
to identify and correct an unsafe condition on an aviation product. The
MCAI describes the unsafe condition as corrosion damage to the elevator
control rod that could lead to failure of the elevator control rod,
possibly resulting in loss of control of the glider. We are issuing
this AD to require actions to address the unsafe condition on these
products.
DATES: This AD is effective September 25, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of September 11,
2012.
We must receive any comments on this AD by October 25, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
On July 18, 2012, we issued AD 2012-15-07, amendment 39-17136 (77
FR 46940, August 7, 2012) for Glasflugel Models Standard Libelle-201B,
Club Libelle 205, Mosquito, and Kestrel gliders. That AD resulted from
mandatory continuing airworthiness information (MCAI) issued by an
aviation authority of another country to identify and correct an unsafe
condition on an aviation product. We issued that AD to require actions
to address the unsafe condition on these products.
Actions Since AD Was Issued
Since we issued AD 2012-15-07, amendment 39-17136 (77 FR 46940,
August 7, 2012), compliance with the existing AD required operators to
not install an elevator control rod with a control bore hole. An
operator reported that the improved replacement rods, as expected, have
no control bore hole on the side at the top of the rod where there had
previously been a hole. However, the improved replacement rods do have
a new drain hole at the bottom of the rod between the forks. The
operator expressed confusion as to whether this drain hole would cause
the new rod to not be in compliance since there was no clarification of
``on the side.''
Relevant Service Information
Glasfaser Flugzeug-Service GmbH has issued Technical Note TN 201-
40, TN 205-27, TN 206-26, TN 303-25, TN 304-12, TN 401-30, TN 501-10,
and TN 604-11, Revision 1, dated July 14, 2011 (EASA translation
approval dated September 9, 2011). The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
AD Requirements
This AD retains the actions from AD 2012-15-07 but adds the
language of ``on the side'' to assure that the replacement control rod,
which has an additional drain hole at the rod bottom between the forks,
is an acceptable configuration for compliance.
FAA's Justification and Determination of the Effective Date
This action incorporates clarification that the additional drain
hole at the rod bottom between the forks on the replacement control
rods is the acceptable configuration for compliance and does not
require any additional work for those airplanes. Therefore, we find
that notice and opportunity for prior public comment are unnecessary
and that good cause exists for making this amendment effective in less
than 30 days.
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 before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
the docket number FAA-2012-0046 and directorate identifier 2011-CE-040-
AD at the beginning of your comments. We
[[Page 55412]]
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD will affect 54 products of U.S. registry.
We also estimate that it would take about 6 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts would cost about $333 per product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $45,522, or $843 per product.
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 above, I certify this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, 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.
Examining the AD Docket
You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.
