The installation must follow a plan (called a \"scheme\") that has been approved by the Secretary (the senior government official responsible for aviation safety).\n\n**Deadline:** The modification had to be completed before 1 September 1972.\n\n**Why it matters:** Safety harnesses prevent serious injury by securing the upper body during turbulence, hard landings, or accidents—significantly improving protection compared to lap belts alone."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications","history":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications/history","analysis":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications/analysis","conflicts":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications/conflicts","importantCases":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications/important-cases","documents":"/api/acts/ad-pa-20-10-front-seat-restraint-installations-modifications/documents"}}
