An aircraft that does not comply cannot be flown legally, as it is not considered airworthy. This specific directive addresses a safety issue with the fuel selector valve to prevent potential fuel system failures."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification","history":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification/history","analysis":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification/analysis","conflicts":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification/conflicts","importantCases":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification/important-cases","documents":"/api/acts/ad-pa-30-10-fuel-selector-valve-modification/documents"}}
