That earlier instrument had granted specific authorisations and permissions for helicopter winching (where helicopters lower or raise people or equipment using a winch cable).\n- **Who it affects**: Helicopter operators who were relying on the permissions in CASA 33/16 for winching operations.\n- **Why it matters**: Operators can no longer rely on the specific exemptions or permissions that were in the old instrument. They must now comply with the standard Civil Aviation Regulations or seek alternative approvals from CASA."}},"importantCases":[],"_links":{"self":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations","history":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations/history","analysis":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations/analysis","conflicts":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations/conflicts","importantCases":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations/important-cases","documents":"/api/acts/casa-48-17-repeal-of-authorisation-and-permission-helicopter-winching-operations/documents"}}
