Schempp-Hirth Flugzeugbau GmbH Gliders
This AD applies to Schempp-Hirth Flugzeugbau GmbH Model Janus, Mini-Nimbus HS-7, Nimbus-2, and Standard Cirrus gliders, with a serial number listed in 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), certificated in any category.
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.
Within 90 days after the effective date of this AD, do the following actions concurrently.
(1) Install colored markings on the elevator in accordance with Action 1 in 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).
(2) Revise the existing aircraft flight manual (FM) and service manual (SM) for your glider by replacing the pages specified in Action 2 in 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), as applicable to your glider, with the revised pages for the manual applicable to your glider dated June 2020.
(3) The action required by paragraph (g)(2) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
