This Directive was based on USA Directive 72-24-02. This Directive and 74-24-02 required compliance in 1973 so the unsafe condition no longer exists. |\n\n![](image.001.png)\n\nJames Coyne  \nDelegate of the Civil Aviation Safety Authority\n\n24 April 2008","sortOrder":0},{"sectionNumber":"AD/PA-28/41","sectionType":"part","heading":"AD/PA-28/41","content":"## AD/PA-28/41","sortOrder":1},{"sectionNumber":"Rapid Throttle Movement - Warning Placar","sectionType":"part","heading":"Rapid Throttle Movement - Warning Placard","content":"## Rapid Throttle Movement - Warning Placard","sortOrder":2},{"sectionNumber":"6/2008","sectionType":"part","heading":"6/2008","content":"## 6/2008","sortOrder":3}],"analysis":{"kimi_summary":{"_metrics":{"model":"kimi-k2.5","source":"moonshot-batch","completionTokens":1201},"content_quality":"ok","complexity_score":1,"scope_assessment":{"changed":false,"description":"The instrument performs exactly as described—it cancels an outdated airworthiness directive.

Rapid throttle movement could cause engine issues in these aircraft.\n\n**Why it's being cancelled:** Compliance was mandatory back in 1973—over 35 years ago. Since every affected aircraft has long since had the placard installed, the safety risk no longer exists. The rule is essentially housekeeping—removing a redundant requirement from the books.\n\n**Who issued it:** The Civil Aviation Safety Authority (CASA), which regulates Australian aviation safety.\n\n**Effect:** Aircraft operators no longer need to reference or comply with this specific directive, though any placards already installed can remain."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled","history":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled/history","analysis":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled/important-cases","documents":"/api/acts/ad-pa-28-41-rapid-throttle-movement-warning-placard-cancelled/documents"}}
