The harnesses must be fitted according to a scheme approved by the Secretary (the relevant government official).\n\n**Who it affects**\n\nAnyone operating these particular twin-engine Beechcraft Baron aeroplanes.\n\n**Why it matters**\n\nThis is a critical safety upgrade to protect pilots and front-seat passengers during accidents, hard landings, or severe turbulence. The directive ensures occupants have proper shoulder harness restraint rather than just basic lap belts, significantly reducing the risk of serious injury or death. The original compliance deadline for this modification was 1 September 1972."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-55-25-front-seat-restraint-installations","history":"/api/acts/ad-beech-55-25-front-seat-restraint-installations/history","analysis":"/api/acts/ad-beech-55-25-front-seat-restraint-installations/analysis","conflicts":"/api/acts/ad-beech-55-25-front-seat-restraint-installations/conflicts","importantCases":"/api/acts/ad-beech-55-25-front-seat-restraint-installations/important-cases","documents":"/api/acts/ad-beech-55-25-front-seat-restraint-installations/documents"}}
