The installation must follow a plan approved by the Secretary (the senior government official responsible for aviation at that time).\n\n**Why it matters:** This improves pilot and passenger safety by ensuring front seats have proper restraint systems to protect people during turbulence or accidents.\n\n**Deadline:** The modification had to be completed before 1 September 1972."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification","history":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification/history","analysis":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification/analysis","conflicts":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification/conflicts","importantCases":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification/important-cases","documents":"/api/acts/ad-pa-23-47-front-seat-restraint-installations-modification/documents"}}
