As all affected aircraft would have been inspected, this AD is no longer required. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n22 May 2008","sortOrder":0},{"sectionNumber":"AD/CESSNA 180/50","sectionType":"part","heading":"AD/CESSNA 180/50","content":"## AD/CESSNA 180/50","sortOrder":1},{"sectionNumber":"Elevator Control Travel","sectionType":"part","heading":"Elevator Control Travel","content":"## Elevator Control Travel","sortOrder":2},{"sectionNumber":"7/2008","sectionType":"part","heading":"7/2008","content":"## 7/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":2219},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument terminates the airworthiness directive entirely rather than expanding its scope.
