Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Schempp-Hirth Flugzeugbau GmbH Model Janus, Mini-Nimbus HS- 7, Nimbus-2, and Standard Cirrus gliders. This proposed 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 proposed AD would require installing colored markings and revising the existing aircraft flight manual (FM) and service manual (SM). The FAA is proposing this AD to address the unsafe condition on these products.

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 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.
[[Page 56]]
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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
1170.
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 contains 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.
FAA's 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 FAA's 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 NPRM
after determining the unsafe condition described previously 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.''
Differences Between This Proposed AD and the MCAI
The MCAI applies to Schempp-Hirth Flugzeugbau GmbH Model Standard
Cirrus B, Standard Cirrus CS 11-75L, and Nimbus-2M gliders, and this
proposed AD would not because these models do not have an FAA type
certificate.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 87 gliders of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost glider operators
----------------------------------------------------------------------------------------------------------------
Install markings...................... 1 work-hour x $85 per $10 $95 $8,265
hour = $85.
Revise FM and SM...................... 1 work-hour x $85 per 0 85 7,395
hour = $85.
----------------------------------------------------------------------------------------------------------------
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
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
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
