The AD compliance was within 100 hours time in service after31 May 1976. As all aircraft would have been inspected by now, the AD is no longer required. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n25 August 2008","sortOrder":0},{"sectionNumber":"AD/CESSNA 206/19","sectionType":"part","heading":"AD/CESSNA 206/19","content":"## AD/CESSNA 206/19","sortOrder":1},{"sectionNumber":"Rudder Trim Chain","sectionType":"part","heading":"Rudder Trim Chain","content":"## Rudder Trim Chain","sortOrder":2},{"sectionNumber":"11/2008","sectionType":"part","heading":"11/2008","content":"## 11/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1708},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument terminates the regulatory requirement entirely rather than expanding its scope.
