It requires owners or operators to **install safety harnesses in the front seats** of these planes to improve occupant protection. The installation must follow a design approved by the **Secretary** (the senior government official responsible for aviation at the time). This safety modification had to be completed **before 1 September 1972**.\n\n**Why it matters:** This rule was introduced to prevent injuries by ensuring front-seat occupants in these specific twin-engine aircraft were properly secured with harnesses rather than basic lap belts."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification","history":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification/history","analysis":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification/analysis","conflicts":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification/conflicts","importantCases":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification/important-cases","documents":"/api/acts/ad-pa-30-14-front-seat-restraint-installations-modification/documents"}}
