This affected only aircraft with reclining seat backs that have been moved further aft to provide additional leg room. As all aircraft would have completed this modification, the unsafe condition no longer exists. |\n\n![](image.001.png)\n\nDavid Villiers  \nDelegate of the Civil Aviation Safety Authority\n\n19 December 2007","sortOrder":0},{"sectionNumber":"AD/CESSNA 150/19","sectionType":"part","heading":"AD/CESSNA 150/19","content":"## AD/CESSNA 150/19","sortOrder":1},{"sectionNumber":"Seat Frame","sectionType":"part","heading":"Seat Frame","content":"## Seat Frame","sortOrder":2},{"sectionNumber":"2/2008","sectionType":"part","heading":"2/2008","content":"## 2/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":855},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"The legislation performs exactly its stated function: cancelling an obsolete airworthiness directive.

Because all affected aircraft would have made these repairs by now, the safety risk no longer exists, so the rule is no longer needed.\n\n**Why it matters:** If you own one of these aircraft, you no longer need to comply with this specific seat frame reinforcement requirement because the directive has been formally cancelled by the Civil Aviation Safety Authority."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-150-19-seat-frame-cancelled","history":"/api/acts/ad-cessna-150-19-seat-frame-cancelled/history","analysis":"/api/acts/ad-cessna-150-19-seat-frame-cancelled/analysis","conflicts":"/api/acts/ad-cessna-150-19-seat-frame-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-150-19-seat-frame-cancelled/important-cases","documents":"/api/acts/ad-cessna-150-19-seat-frame-cancelled/documents"}}
