You must check whether you now need a fresh authorisation (permission, direction or approval) from CASA to continue those activities. This is essentially a housekeeping measure to clear out old or superseded approvals, but operators must ensure they are not left operating without valid authority."}},"importantCases":[],"_links":{"self":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations","history":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations/history","analysis":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations/analysis","conflicts":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations/conflicts","importantCases":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations/important-cases","documents":"/api/acts/casa-421-10-revocation-of-authorisations-permissions-and-directions-helicopter-special-operations/documents"}}
