This Directive was not based on a Piper service document or a USA Directive. This Directive has been in force since 1964 so all affected aircraft would have been modified long ago. Hence, this AD is no longer required. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n19 May 2008","sortOrder":0},{"sectionNumber":"AD/PA-22/22","sectionType":"part","heading":"AD/PA-22/22","content":"## AD/PA-22/22","sortOrder":1},{"sectionNumber":"Rudder Pedals - Modification","sectionType":"part","heading":"Rudder Pedals - Modification","content":"## Rudder Pedals - Modification","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":2297},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument terminates the original Airworthiness Directive entirely rather than expanding or altering its scope.
