It is legally enforceable—operators cannot fly these aircraft beyond the compliance deadline without completing the required inspection."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection","history":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection/history","analysis":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection/analysis","conflicts":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection/conflicts","importantCases":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection/important-cases","documents":"/api/acts/ad-pa-24-31-landing-gear-and-flap-assemblies-inspection/documents"}}
