The cancellation means they no longer need to follow this specific directive, but must instead comply with a newer, broader safety rule (AD/GENERAL/74 Amendment 1).\n\n**Why it matters**\n\nSafety standards are updated over time. This 1972 rule requiring upper torso restraints (shoulder straps) has been absorbed into a more comprehensive, modern regulation. The cancellation removes redundant requirements from the rulebook, ensuring pilots and mechanics follow current consolidated standards rather than outdated individual directives."}},"importantCases":[],"_links":{"self":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled","history":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled/history","analysis":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled/analysis","conflicts":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled/conflicts","importantCases":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled/important-cases","documents":"/api/acts/ad-aus-20-front-seat-restraint-installation-cancelled/documents"}}
