The AD compliance was prior to issue of a certificate of Airworthiness. As all aircraft would have been modified, the AD is no longer required. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n24 April 2009","sortOrder":0},{"sectionNumber":"AD/AA-5/2","sectionType":"part","heading":"AD/AA-5/2","content":"## AD/AA-5/2","sortOrder":1},{"sectionNumber":"Front Seat - Modification","sectionType":"part","heading":"Front Seat - Modification","content":"## Front Seat - Modification","sortOrder":2},{"sectionNumber":"6/2009","sectionType":"part","heading":"6/2009","content":"## 6/2009","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1358},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument simply terminates a specific 1972 Airworthiness Directive that is no longer needed.
