DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2012-0046; Directorate Identifier 2011-CE-040-AD; 
Amendment 39-17186; AD 2012-15-07 R1]
RIN 2120-AA64


Airworthiness Directives; Glasflugel Gliders

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

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.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at Document Management Facility, U.S.

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 http://www.regulations.gov, 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 http://www.regulations.gov; 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.
