As the requirements are included in the Flight Manual, the AD is no longer required. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n6 November 2008","sortOrder":0},{"sectionNumber":"AD/BELL 412/7 Amdt1","sectionType":"part","heading":"AD/BELL 412/7 Amdt1","content":"## AD/BELL 412/7 Amdt1","sortOrder":1},{"sectionNumber":"Airspeed and Ground Operation Restrictio","sectionType":"part","heading":"Airspeed and Ground Operation Restriction","content":"## Airspeed and Ground Operation Restriction","sortOrder":2},{"sectionNumber":"13/2008","sectionType":"part","heading":"13/2008","content":"## 13/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1528},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This amendment does not expand the scope of the legislation.
