Continuing airworthiness notices | aviation.govt.nz

The CAA will issue a continuing airworthiness notice (CAN) to bring industry attention to an issue which does not necessarily meet the threshold of an ‘unsafe condition’ – which would warrant an airworthiness directive (AD). A CAN alerts, educates, recommends and guides, however compliance with the details of a CAN is not mandatory.

List of CANs on the CAA website as at October 2025 [XLSX 43 KB]

If you have any questions or queries about CANs, email airworthinessdirectives@caa.govt.nz.
