These limits are set out in the aircraft's official maintenance manual (Chapter 5 of the Canadair CL-600 Maintenance Manual).\n\n**Why it matters:** This makes legally binding what was previously just a manufacturer recommendation. It ensures critical parts are replaced before they wear out, preventing mechanical failures and keeping passengers safe."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks","history":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks/history","analysis":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks/analysis","conflicts":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks/conflicts","importantCases":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks/important-cases","documents":"/api/acts/ad-cl-600-30-time-limits-and-maintenance-checks/documents"}}
