This 2007 document withdraws that old rule entirely because the safety risk it addressed no longer exists—likely because all affected aircraft have long since been fitted with harnesses or retired from service.\n\n**When it takes effect:** The cancellation happens on 20 December 2007.\n\n**Why it matters:** It removes a regulatory burden. Owners no longer need to comply with a 36-year-old directive that has become redundant."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled","history":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled/history","analysis":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled/analysis","conflicts":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled/conflicts","importantCases":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled/important-cases","documents":"/api/acts/ad-beech-18-16-front-seat-restraint-installations-modification-cancelled/documents"}}
