They must:\n1. Use an **approved alternative system** to record flight hours that still meets airworthiness safety standards\n2. **Document the method** in their maintenance control manual (the rulebook for how they manage aircraft upkeep)\n\nThis creates a flexible, streamlined paperwork option for simpler aircraft while ensuring safety through alternative record-keeping systems."}},"importantCases":[],"_links":{"self":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio","history":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio/history","analysis":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio/analysis","conflicts":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio/conflicts","importantCases":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio/important-cases","documents":"/api/acts/casa-ex42-08-exemption-time-in-service-recording-on-maintenance-release-determination-non-applicatio/documents"}}
