Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH 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 
Schempp-Hirth Flugzeugbau GmbH Models Discus-2a, Discus-2b, Discus-2c, 
Discus 2cT, Ventus-2a, and Ventus-2b 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 insufficient overlap of the airbrake panels. We are 
issuing this proposed AD to require actions to address the unsafe 
condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2016-0027, dated February 9, 2016 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    Operational experience shows that, under certain conditions, the 
overlap between the two airbrake panels can be insufficient and the 
panels can interlock.
    This condition, if not corrected, could lead to blockage of the 
airbrakes, possibly resulting in reduced control of the (powered) 
sailplane.
    To address this potential unsafe condition, Schempp-Hirth 
Flugzeugbau GmbH issued TN 349-39, 360-29, 825-55 and 863-22 (single 
document, hereafter referred to as `the TN' in this AD), to provide 
inspection instructions to verify the correct overlap between the 
two affected airbrake panels.
    For the reason described above, this AD requires a one-time 
inspection of the overlap of the affected airbrake panels and, 
depending on findings, accomplishment of applicable corrective 
action(s).

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
6123.

Related Service Information Under 1 CFR Part 51

    Schempp-Hirth Flugzeugbau GmbH has issued Technical Note No. 349-
39, 360-29, 825-55, 863-22; dated January 29, 2016 (published as a 
single document), and Arbeitsanweisung (English translation: Working 
instructions) for Technische Mitteilung Nr. (English translation: 
Technical Note No.) 349-39, 360-29, 825-55, 863-22, Ausgabe (English 
translation: Issue) 1, Datum (English translation: Dated) January 22, 
2016. The service information describes procedures for inspection of 
the overlap of the airbrake panels and, if necessary, replacement of 
the airbrake panels. This service information is reasonably available 
because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section 
of this NPRM.

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 86 products of U.S. 
registry. We also estimate that it would take about 2 work-hours per 
product to comply with the basic requirements of this proposed AD.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $14,620, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 4 work-hours and require parts

[[Page 24744]]

costing $100, for a cost of $440 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 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

Schempp-Hirth Flugzeugbau GmbH: Docket No. FAA-2016-6123;

product. The MCAI describes the unsafe condition as insufficient 
overlap of the airbrake panels. We are issuing this proposed AD to 
require actions to address the unsafe condition on these products. 
We are issuing this AD to prevent interlocking of the airbrake 
panels, which could lead to blockage of the airbrakes and possible 
loss of control.

 (f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) and (f)(2) of this AD:
    (1) Within the next 40 days after the effective date of this AD,
