FAILURE OF FLAP DRIVE MECHANISM IN FUSELAGE 

During a Daily Inspection of a Mini-Nimbus C, a failure in the flap mechanism was found. Subsequent investigation showed that the torsion drive lever had failed at the welding joints. The same system is employed in the Mini-Nimbus HS7, Mini-Nimbus B and Nimbus-2C.  The LBA has issued AD-2005-239. Schempp-Hirth has issued Technical Note No. 286-35/328-13, and an appendix to that TN which included drawing HS5-10.065/3 for the Nimbus 2C, and drawing HS7-10.083/1 for the Mini-Nimbus. These documents form part of this AD.
