Any aircraft still flying should already have this modification completed.*"}},"importantCases":[],"_links":{"self":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification","history":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification/history","analysis":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification/analysis","conflicts":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification/conflicts","importantCases":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification/important-cases","documents":"/api/acts/ad-aa-1-10-front-seat-restraint-installation-modification/documents"}}
