The installation must follow a specific plan (*scheme*) that is approved by the Secretary (the senior government official responsible for aviation safety at the time).\n\n**How to comply:** Guidelines for creating your installation plan are found in *Airworthiness Advisory Circular No. 62* (March 1972). The work had to be completed before 1 October 1973.\n\n**Why this matters:** This prevents injuries by ensuring pilots and front passengers are properly restrained during turbulence or accidents."}},"importantCases":[],"_links":{"self":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification","history":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification/history","analysis":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification/analysis","conflicts":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification/conflicts","importantCases":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification/important-cases","documents":"/api/acts/ad-dha-3-26-front-seat-restraint-installation-modification/documents"}}
