The AD compliance was prior to 31 December 1984. 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\n16 February 2009","sortOrder":0},{"sectionNumber":"AD/BELL 212/31","sectionType":"part","heading":"AD/BELL 212/31","content":"## AD/BELL 212/31","sortOrder":1},{"sectionNumber":"Float Bags - Inspection","sectionType":"part","heading":"Float Bags - Inspection","content":"## Float Bags - Inspection","sortOrder":2},{"sectionNumber":"4/2009","sectionType":"part","heading":"4/2009","content":"## 4/2009","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1571},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"This instrument represents the natural conclusion of the original AD's scope.

The deadline to complete this inspection was 31 December 1984.\n\n**Why it's being cancelled:** Since the inspection was mandatory over 20 years ago, every affected helicopter has already been checked. The rule is now redundant, so the Civil Aviation Safety Authority (CASA) is formally cancelling it as of 9 April 2009 to clean up the rulebooks."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled","history":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled/history","analysis":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled/analysis","conflicts":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled/conflicts","importantCases":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled/important-cases","documents":"/api/acts/ad-bell-212-31-float-bags-inspection-cancelled/documents"}}
