Airworthiness Directive · Amendment 39-21255 · Equipment/furnishing
Glasflugel
This AD applies to Glasflugel Models Club Libelle 205, H 301 “Libelle,” H 301B “Libelle,” Kestrel, Mosquito, Standard “Libelle,” and Standard Libelle-201B gliders, certificated in any category, with a center of gravity (C.G.) tow release installed.
The FAA is superseding Airworthiness Directive (AD) 2018-21-04 for Glasflugel Models Club Libelle 205, H 301 "Libelle," H 301B "Libelle," Kestrel, Mosquito, Standard "Libelle," and Standard Libelle-201B gliders. This AD results from 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 jamming between the double two-ring end of the towing cable and the deflector angles of the center of gravity (C.G.) release mechanism. The FAA is issuing this AD to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) through (3) of this AD.
(1) Before the next winch launch after November 13, 2018 (the effective date of AD 2018-21-04) and then within 30 days after the effective date of this AD or 12 months after the initial inspection, whichever occurs later, and thereafter at intervals not to exceed 12 months, inspect the distance between the deflector-angles by following paragraph 1 in the Actions section of Glasfaser-Flugzeug-Service GmbH Technical Note No. 5-2018, dated June 25, 2018.
(2) If the distance is less than 36 mm during any inspection required in paragraph (f)(1) of this AD, before the next winch launch, do the corrective action in paragraph 2 in the Actions section of Glasfaser-Flugzeug-Service GmbH Technical Note No. 5-2018, dated June 25, 2018.
(3) Before the next winch launch after November 13, 2018 (the effective date of AD 2018-21-04), revise the flying operations section of the sailplane flight manual by inserting the text in paragraph (f)(3)(i) of this AD into the winch tow section.
(i) Winch launching is permissible only with a connecting ring pair that conforms to aeronautical standard LN 65091.
(ii) This action may be done 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 by following 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, 121.380, or 135.439.
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.
