ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued by the aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
It has been reported by DG-808 C owners that the bolt at the
landing gear control bellcrank was found mounted in the wrong
direction. Further investigations have shown that in such situation,
the bolt could interfere and damage:
--The air brake control pushrod, and
--The wing flap control pushrod if the landing gear is operated with
negative flap settings.
This condition, if not detected and corrected, may lead to
reduce the controllability of the powered sailplane.
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.
DATES: This AD becomes effective May 2, 2011.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No.: 2011-0053-E, dated March 24, 2011 (referred to after this as
``the MCAI''), to correct an unsafe condition for the specified
products. The MCAI states:
It has been reported by DG-808 C owners that the bolt at the
landing gear control bellcrank was found mounted in the wrong
direction. Further investigations have shown that in such situation,
the bolt could interfere and damage:
--The air brake control pushrod, and
--The wing flap control pushrod if the landing gear is operated with
negative flap settings.
This condition, if not detected and corrected, may lead to
reduce the controllability of the powered sailplane.
For the reasons described above, this AD requires to inspect the
landing gear control bellcrank bolt for proper installation and the
accomplishment of the associated corrective actions, as applicable.
EASA issued AD No.: 2011-0053-E based on their determination that this
was a production error and a quality control problem. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
DG Flugzeugbau GmbH has issued Technical note No. 800/40, dated
February 14, 2011; and Section A-A of Undercarriage control circuit
Diagram 15, dated November 2004, of DG Flugzeugbau GmbH Maintenance
Manual for the Motorglider DG-808C, dated June 2005. 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 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 issuing this AD because we
evaluated all information provided by the State of Design Authority and
determined the unsafe condition exists and is likely to exist or
develop on other products of the same type design.
[[Page 23170]]
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might have also required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
described in a separate paragraph of the AD. These requirements take
precedence over those copied from the MCAI.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because it
has been reported that bolts at the landing gear control bellcrank were
mounted in the wrong direction. The incorrectly mounted bolt could
interfere and damage the air brake control pushrod and the wing flap
control pushrod if the landing gear is operated with negative flap
settings. This condition, if not detected and corrected, may lead to
reducing the controllability of the powered sailplane. Therefore, we
determined that notice and opportunity for public comment before
issuing this AD are impracticable and that good cause exists for making
this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2011-0409; Directorate
Identifier 2011-CE-011-AD'' at the beginning of your comments. We
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 5 products of U.S. registry.
We also estimate that it would take about 0.5 work-hour 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 $0 per product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $213, or $43 per product.
In addition, we estimate that any necessary follow-on actions would
take about 0.5 work-hour and require parts costing $250, for a cost of
$293 per product. We have no way of determining the number of products
that may need these actions.
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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
