However, since the original rule required compliance by November 1968, all affected planes were modified decades ago.\n\n**Why it matters:** The Civil Aviation Safety Authority is removing obsolete rules from the books. Because every affected aircraft was required to complete this modification nearly 40 years ago, the rule is no longer necessary and is being cancelled to reduce regulatory clutter."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled","history":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled/history","analysis":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled/analysis","conflicts":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled/conflicts","importantCases":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled/important-cases","documents":"/api/acts/ad-beech-56-3-cabin-door-latch-cancelled/documents"}}
