It used to set rules about how long certain engine parts could be used before they had to be replaced on Turbomeca Artouste series turbine engines. These are \"life-limited components\" — parts that wear out and must be retired after a set number of flight hours or cycles for safety reasons.\n\n**Why it was cancelled:** The rules about tracking and replacing life-limited engine parts have been moved to a different directive: **AD/ENG/7**. Rather than having separate rules for each engine type, CASA consolidated them into one overarching directive.\n\n**Who it affects:** Anyone who operates or maintains aircraft with Turbomeca Artouste engines. They must now follow AD/ENG/7 instead of this cancelled directive.\n\n**Why it matters:** Even though this specific directive is dead, the safety requirements live on elsewhere. Operators need to know which rulebook to follow — and this cancellation notice prevents confusion about whether the old rules still apply."}},"importantCases":[],"_links":{"self":"/api/acts/ad-artouste-1-engine-components-life-limitations","history":"/api/acts/ad-artouste-1-engine-components-life-limitations/history","analysis":"/api/acts/ad-artouste-1-engine-components-life-limitations/analysis","conflicts":"/api/acts/ad-artouste-1-engine-components-life-limitations/conflicts","importantCases":"/api/acts/ad-artouste-1-engine-components-life-limitations/important-cases","documents":"/api/acts/ad-artouste-1-engine-components-life-limitations/documents"}}
