RIN 2120-AA64


Airworthiness Directives; Glasflugel Gliders

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

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Glasflugel Models Standard Libelle-201B, Club Libelle 205, Mosquito, 
and Kestrel gliders. This proposed AD results from mandatory continuing 
airworthiness information (MCAI) originated 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 proposed AD to require actions to address 
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by March 5, 2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent

[[Page 2675]]

for the Member States of the European Community, has issued EASA AD 
No.: 2011-0213R1, dated November 8, 2011 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    A broken elevator control rod in the vertical fin on a Kestrel 
sailplane has been reported. The technical investigation revealed 
that water had soaked into the elevator control rod through a 
control bore hole and resulted in corrosion damage. The 
investigation concluded as well that the corrosion cannot be 
detected from outside the elevator control rod.
    This condition, if not detected and corrected, could lead to 
failure of the elevator control rod, possibly resulting in loss of 
control of the sailplane.
    To address this unsafe condition, Glasfaser Flugzeug-Service 
GmbH have developed and published Technical Note (TN) TN 201-40, TN 
205-27, TN 206-26, TN 303-25, TN 304-12, TN 401-30, TN 501-10, TN 
604-11, which provides instructions for elevator control rod 
inspection and replacement.
    For the reasons described above, EASA issued AD 2011-0213 to 
require a one-time inspection and replacement of the affected 
elevator control rod with an improved part.

You may obtain further information by examining the MCAI in the AD 
docket.

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 and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed 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 proposed 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 proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.
