This condition could result in the premature development of cracks in the flap vane brackets, and if not corrected, lead to in- flight loss of the flap vane and subsequent reduced controllability of the aircraft.\n\n![Signature of David Alan Villiers Delegate of the Civil Aviation Safety Authority](image.002.jpeg)  \n\nDavid Alan Villiers\n\nDelegate of the Civil Aviation Safety Authority 24 October 2002\n\n![](image.001.png)","sortOrder":1}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This AD maintains its original narrow scope: addressing a specific manufacturing defect in flap vane brackets on a limited range of aircraft serial numbers.
