However, the original rule required compliance by 1972, so most aircraft would have been modified decades ago.\n\n**Why it matters:** The Civil Aviation Safety Authority cancelled this directive because it became obsolete. Once the long-ago compliance deadline passed and the safety modifications were made, keeping the rule on the books served no further purpose."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled","history":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled/history","analysis":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled/analysis","conflicts":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled/conflicts","importantCases":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled/important-cases","documents":"/api/acts/ad-beech-33-11-front-seat-restraint-installation-cancelled/documents"}}
