As of 30 July 2009, those retirement limits have moved into the aircraft's **Airworthiness Limitations** (the standard technical documentation for the helicopter). This means the separate Australian directive is no longer needed and has been cancelled.\n\n**Why it matters**\nYou must still follow the retirement limits for fatigue-critical parts, but you'll now find them in the Airworthiness Limitations section rather than in this separate directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled","history":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled/history","analysis":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled/analysis","conflicts":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled/conflicts","importantCases":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled/important-cases","documents":"/api/acts/ad-as-355-1-amdt-8-retirement-life-fatigue-critical-components-cancelled/documents"}}
