However, because all affected planes have already undergone the required modification over the past 43 years, the rule now applies to effectively no one.\n\n**Why it matters:** The original directive was a temporary safety measure to fix a design flaw. Since compliance is now universal, keeping the rule on the books serves no purpose. Cancelling it removes outdated regulatory clutter while maintaining safety standards."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled","history":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled/history","analysis":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled/analysis","conflicts":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled/conflicts","importantCases":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled/important-cases","documents":"/api/acts/ad-cessna-210-7-elevator-tab-actuator-modification-cancelled/documents"}}
