Normally, these expire after set periods defined in the regulations. CASA had previously granted exemption EX05/06, which let some operators use alternative timeframes. This instrument cancels that exemption.\n\n**Who it affects:** Aircraft operators and maintenance organisations who were relying on exemption EX05/06 to use different validity periods for their maintenance releases.\n\n**What changes:** Affected operators must now follow the standard timeframes in the Civil Aviation Safety Regulations for how long maintenance releases stay in force, rather than the alternative arrangements allowed by the old exemption.\n\n**When it starts:** The day after this instrument is officially registered."}},"importantCases":[],"_links":{"self":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas","history":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas/history","analysis":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas/analysis","conflicts":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas/conflicts","importantCases":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas/important-cases","documents":"/api/acts/casa-ex60-12-revocation-of-exemption-from-period-that-maintenance-release-is-in-force-instrument-cas/documents"}}
