This directive ensures potential defects are found before they become dangerous. Airworthiness Directives are **legally binding** — failure to comply means the aircraft cannot legally fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection","history":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection/history","analysis":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection/analysis","conflicts":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection/conflicts","importantCases":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection/important-cases","documents":"/api/acts/ad-gazelle-7-amdt-1-landing-gear-legs-inspection/documents"}}
