This directive ensures a critical safety modification is completed on affected aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement","history":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement/history","analysis":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement/analysis","conflicts":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement/conflicts","importantCases":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement/important-cases","documents":"/api/acts/ad-rock-114-6-fuel-selector-valve-replacement/documents"}}
