It requires them to permanently remove specific helicopter parts from service once they reach a predetermined age or usage limit (called their \"fatigue life\").\n\n**Who it affects:** Anyone who owns or operates any model of Eurocopter BO 105 series helicopters.\n\n**The requirement:** Operators must retire (stop using) the components listed in the BO 105 Maintenance Manual, Volume 4, Chapter 101, Paragraph 101-9, Revision 10, at or before the time limits specified in that manual.\n\n**Why it matters:** Helicopter parts weaken over time due to stress and vibration (metal fatigue). This rule prevents mechanical failures and crashes by ensuring old, worn-out parts are replaced before they can break."}},"importantCases":[],"_links":{"self":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations","history":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations/history","analysis":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations/analysis","conflicts":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations/conflicts","importantCases":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations/important-cases","documents":"/api/acts/ad-bo-105-7-amdt-1-fatigue-life-limitations/documents"}}
