 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2021-1170; Project Identifier MCAI-2020-01572-G; Amendment 39-21970; AD 2022-06-04]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Schempp-Hirth Flugzeugbau GmbH Model Janus, Mini-Nimbus HS-7, Nimbus-2, and Standard Cirrus gliders. This AD was prompted by 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 a disconnected pendulum elevator. This AD requires installing colored markings and revising the existing aircraft flight manual (FM) and service manual (SM). The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective May 9, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 9, 2022.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Schempp-Hirth Flugzeugbau GmbH Model Janus, Mini-Nimbus HS-7, Nimbus-2, and Standard Cirrus gliders. The NPRM published in the 
                    **Federal Register**
                     on January 3, 2022 (87 FR 55). The NPRM was prompted by MCAI originated by the European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2020-0260, dated November 26, 2020 (referred to after this as “the MCAI”), to address an unsafe condition on certain serial numbered Schempp-Hirth Flugzeugbau GmbH Model Janus, Mini-Nimbus HS 7, Nimbus-2, Standard Cirrus, Standard Cirrus B, Standard Cirrus CS 11-75L, and Nimbus-2M gliders. The MCAI states: During an aero tow of a Standard Cirrus, the pendulum elevator disconnected. The technical investigation concluded that the elevator attachment was not properly locked. Due to similarity of design, this kind of event could also occur on other Schempp-Hirth sailplanes, including Nimbus-2M powered sailplanes. This condition, if not corrected, could lead to failure of the elevator connection and loss of control of the (powered) sailplane. To address this potential unsafe condition, Schempp-Hirth published the [technical note] TN, providing instructions to install an optical indicator and to update the Aircraft Flight Manual (AFM). For the reasons described above, this [EASA] AD requires installation of an optical indicator and amendment of the AFM. You may examine the MCAI in the AD docket at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2021-1170. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Schempp-Hirth Flugzeugbau GmbH Technical Note No. 278-40/286-36/295-33/328-14/798-4, Revision 1, dated November 12, 2020 (issued as one document). The service information specifies procedures for installing colored markings to the top of the elevator on both sides of the locking mechanism and revising the existing aircraft FM and SM. 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

 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. 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 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) Will not affect intrastate aviation in Alaska, 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.
