Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-0409; Directorate Identifier 2011-CE-011-AD; 
Amendment 39-16678; AD 2011-09-16]
RIN 2120-AA64


Airworthiness Directives; DG Flugzeugbau GmbH Glaser-Dirks Model 
DG-808C Gliders

AGENCY: Federal Aviation Administration (FAA), DOT.

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.
    On May 2, 2011, the Director of the Federal Register approved the 
incorporation by reference of certain publications listed in this AD.
    We must receive comments on this AD by June 10, 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 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 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.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (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.

[[Page 23171]]

Technical note No. 800/40, dated February 14, 2011.
    (2) If, during the inspection required by paragraph (f)(1) of 
this AD, the bolt is found mounted in the wrong direction, before 
further flight, do the following actions:
    (i) Install the landing gear control bellcrank bolt M6x26 LN9037 
and its washers and nut correctly following DG-Flugzeugbau GmbH 
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.
    (ii) Inspect the air brake control pushrod (part number (P/N) 
6St13) and the wing flap control pushrod (P/N 8St7) for damage. If 
any pushrod is damaged, before further flight, replace it with a 
serviceable part following DG-Flugzeugbau GmbH Technical note No. 
800/40, dated February 14, 2011.
