However, because the original rule required compliance by 1982, all affected planes would have been modified decades ago.\n\n**Why it matters:** As of **3 July 2008**, the old modification requirement is scrapped as redundant. This is housekeeping to remove spent rules from the statute books, acknowledging that the safety issue was resolved long ago."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled","history":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled/history","analysis":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled/analysis","conflicts":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled/conflicts","importantCases":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled/important-cases","documents":"/api/acts/ad-beech-77-9-nose-landing-gear-axle-cancelled/documents"}}
