Inertia reels are especially critical in training aircraft, where student pilots may encounter situations requiring rapid deceleration protection."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations","history":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations/history","analysis":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations/analysis","conflicts":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations/conflicts","importantCases":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations/important-cases","documents":"/api/acts/ad-beech-23-18-amdt-1-front-seat-restraint-installations/documents"}}
