Schempp-Hirth GmbH & Co. KG Models Mini-Nimbus B and Mini-Nimbus HS-7 Sailplanes
This AD applies to Models Mini-Nimbus B and Mini-Nimbus HS-7 sailplanes, all serial numbers, that are certificated in any U.S. category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 failure in the flap actuating circuit. An investigation showed that the lever at the torsional drive in the fuselage failed at the weld. We are issuing this AD to require actions to correct the unsafe condition on these products.
Unless already done, do the following except as stated in paragraph (f) below.
(1) Within the next 90 days after December 1, 2006 (the effective date of this AD), reinforce the flap drive.
(2) Do the reinforcement following Schempp-Hirth Flugzeugbau GmbH. Technical Note No. 286-35/No. 328-13, EASA approved on: July 1, 2005.
None.
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.
