SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on July 29, 2013 (78 FR
45471). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
It was found that the accomplishment instructions provided to
check the powered sailplane's propeller hub and blades were not
sufficient to detect cracks and/or other damage. The results of a
subsequent manual review revealed that some other operating
instructions provided by the sailplane flight and maintenance manual
were neither correct nor sufficient.
This condition, if not corrected, could lead to operation of the
powered sailplane outside its certified limits.
To address this unsafe condition, EASA issued AD 2013-0012 to
require amendment of sailplane flight- and maintenance manuals to
correct the operating instruction deficiencies and inaccuracies and,
for Arcus T sailplanes that had been repaired before the applicable
maintenance manual update, an elevator or wing flap hinge moment
weight check, as applicable.
Since that AD was published, Schempp-Hirth Flugzeugbau GmbH
determined that Action 3 of the accomplishment instructions of
Technical Note (Technische Mitteilung) (TN) 890-13, referenced for
Duo Discus T sailplanes, was incorrect for S/N 1 through 174. To
correct this erroneous maintenance instruction, Schempp-Hirth
Flugzeugbau GmbH issued TN 890-13 issue 2.
For the reasons described above, this AD retains the
requirements of EASA AD 2013-0012, which is superseded, and
requires, for certain Duo Discus T powered sailplanes, the use of
instructions as provided in TN 890-13 issue 2.
The MCAI requires exchange of flight manual pages (which introduces a
repetitive inspection of the power plant), exchange of maintenance
manual pages, exchange of cockpit placards, and transfer of weight and
balance data. EASA AD No.: 2013-0054, dated March 5, 2013, supersedes
EASA AD No. 2013-0012, dated January 15, 2013. No
[[Page 77568]]
FAA action was taken on EASA AD No. 2013-0012. You may examine the MCAI
in the AD docket on the Internet at <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2013-0661-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 45471, July 29,
2013) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (78 FR 45471, July 29, 2013) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 45471, July 29, 2013).
Costs of Compliance
We estimate that this AD will affect 5 products of U.S. registry.
We also estimate that it will take about 2.5 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $50 per product.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $1,312.50, or $262.50 per product.
In addition, we estimate that any necessary follow-on actions will
take about 5 work-hours and require parts costing $3,840, for a cost of
$4,265 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 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.

least a
[[Page 77569]]
private pilot certificate and must be entered into the aircraft
records showing compliance with this AD following 14 CFR Sec. 43.9
(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). The record must be
maintained as required by 14 CFR 91.417, 121.380, or 135.439.
(4) Initially within 30 days after January 28, 2014 (the
effective date of this AD) and repetitively thereafter at intervals
not to exceed 12 calendar months, visually inspect (pre-flight) the
power plant (propeller hub and propeller blades) for cracks or other
damage using the following service information in paragraphs
(f)(4)(i) and (f)(4)(ii) of this AD:
(i) For S/N 1 through 174: Use step (4)(c) of the Visual
inspection of the power plant section on page 4.3.3 of Schempp-Hirth
Flugzeugbau GmbH Duo Discus T Flight Manual issue May 2000, Revision

Schempp-Hirth Flugzeugbau GmbH Technical Note No. 890-13, 2nd issue,
dated March 5, 2013.
Note 1 to paragraph (f)(4)(ii) of this AD: The flight manual
references TN 890-13 and MB 890-8; however, neither are part of the
flight manual. Also, MB 890-8 does not apply to the airplanes
included in the Applicability of this AD.
(5) If any cracks or other damage is found during any inspection
required by paragraph (f)(4) of this AD, before further flight,
replace any parts found with cracks and repair any damage.
(6) The revised SFM pages require pre-flight checks that may be
done by the pilot. However, the inspection actions required in
paragraph (f)(4) of this AD, to include all subparagraphs, are
separate from the pilot pre-flight checks and must be done by a
properly certificated aircraft mechanic.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
