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

Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Gliders

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.

ADDRESSES: For service information identified in this final rule,

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 ADDRESSES section.

Differences Between This AD and the MCAI

    The MCAI applies to Schempp-Hirth Flugzeugbau GmbH Model Standard

[[Page 19368]]

Cirrus B, Standard Cirrus CS 11-75L, and Nimbus-2M gliders, and this AD 
does not because these models do not have an FAA type certificate.

Costs of Compliance

    The FAA estimates that this AD affects 87 gliders of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

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.
