POSSIBLE CRACKING OF THE TRIM WEIGHT ATTACHMENT BRACKET

Applicable to LS 3 and LS 4 variants 1. Visually inspect the trim weight holder for cracks in the welded region between the base plate and the fixture bracket. If cracking is found action 3 must be performed immediately. 2. Measure the thickness of the sheet metal of the trim weight holder. 3. Trim weight holders made from 1 mm sheet metal must be replaced by part number 4R8-19c before 31 July, 1993 as shown in drawing 4BR-48a which forms part of this AD. 4. Some LS 3 aircraft have the bracket welded directly onto the pedal support bracket. Should cracking be found in these brackets GFA must be notified before next flight. Rolladen Schneider Technical Bulletins No. 3040 and 4033 refer.
