Background The European Union Aviation Safety Agency EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20200063, dated March 18, 2020
referred to after this as the MCAI, to address an unsafe condition on Schempp-Hirth Flugzeugbau GmbH
Models Ventus-2a, Ventus-2b, Ventus2c, Ventus-2cM, and Ventus-2cT gliders.
The MCAI states:
Severe corrosion has been found on the inboard flaperon actuation push rod of some sailplanes. Subsequent investigation determined that, when water ballast is dumped in flight, some water may be sucked into the wing upper side and enter the wing via the flaperon push rod. Intruding water may cause corrosion especially on the ball bearing connecting the flaperon push rod to the bell crank inside the wing.
This condition, if not detected and corrected, could lead to hard steering when the ball bearing is damaged or increased play when the ball bearing has failed, possibly resulting in reduced control of the powered sailplane.
To address this potential unsafe condition, Schempp-Hirth Flugzeugbau GmbH issued the technical note TN to provide inspection and replacement instructions.
For the reason described above, this EASA AD requires repetitive inspections of the affected parts, as identified in the TN,

and, depending on findings, replacement with serviceable parts.

Related Service Information Under 1
CFR Part 51
The FAA reviewed Schempp-Hirth Flugzeugbau GmbH Working Instructions for Technical Note No.
34942/82557, Revision 2, dated February 24, 2020. This service information contains procedures for inspecting the pushrod, joint head, and bell crank of the flaperon control of the wings for corrosion or other damage, and replacing or servicing repair if necessary. 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.
Other Related Service Information The FAA also reviewed SchemppHirth Flugzeugbau GmbH Technical Note No. 34942/82557, Revision 2, dated February 24, 2020. This service information specifies inspecting the pushrod, joint head, and bell crank of the flaperon control of the wings by following Schempp-Hirth Flugzeugbau GmbH Working Instructions for Technical Note No. 34942/82557, Revision 2, dated February 24, 2020.
FAAs Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAAs bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA
is issuing this AD because it 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.
Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information already described, except as described under Differences Between this Proposed AD
and the MCAI.

Ventus-2cM, and Ventus-2cT gliders, and this proposed AD would not because they do not have an FAA type certificate.
Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 33
gliders of U.S. registry. The FAA also estimates that it would take about 1
work-hour per glider to comply with the inspection that would be required by this proposed AD. Based on these figures, the FAA estimates the inspection cost of this proposed AD on U.S. operators to be $2,805 or $85 per glider, per inspection cycle.
In addition, the FAA estimates that each repair or replacement action required by this proposed AD would take up to 8 work-hours and require parts costing up to $800. Based on these figures, the FAA estimates the repair or replacement cost of this proposed AD
on U.S. operators to be up to $1,480 per glider.
Authority for This Rulemaking Title 49 of the United States Code specifies the FAAs 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 Agencys authority.
The FAA is 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 The FAA 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 Would not affect intrastate aviation in Alaska, and
