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.

Maintenance flying under Level 3 and 4

Flying private or recreational aircraft for essential maintenance is not currently allowed at Alert Levels 3 and 4. The CAA has been and continues to pursue approval for maintenance required to be carried out on aircraft that are not able to fly under current COVID levels. We are seeking similar dispensations to those put in place during previous COVID conditions and are actively pursuing this through the Ministry of Transport and the Ministry of Health. The Ministry of Health had indicated that previous approvals issued by the CAA were no longer valid and we will publish details of any new scheme as soon as we get the permissions we are seeking. The CAA is aware this is a concern for many private operators and our teams are doing all we can to resolve this potential safety issue.

Latest continuing airworthiness notices

The purpose of this Continuing Airworthiness Notice (CAN) is to advise aircraft operators and maintainers of a CAA finding with the fuel system pressure relief valve (PRV) fitted on the Robinson R44 II involved in an accident on 12 June 2021. The fuel system pressure relief valve (PRV) was found to be bypassing an excessive amount of fuel at a much lower pressure than specified. This in itself is unlikely to cause an engine failure.

The purpose of this Continuing Airworthiness Notice (CAN) is to alert operators and maintainers of the importance of accomplishing a thorough inspection of the flap supports and rollers bearings for wear and corrosion. Service experience indicates the possibility of flap support wear by the flap roller bearings. Failure to accomplish a thorough inspection of the flap supports and roller bearings could result in damage to the flap supports, restriction of flap free movement, and a possible flap asymmetric condition.

The purpose of this Continuing Airworthiness Notice (CAN) is to advise operators and maintainers of Guimbal Cabri G2 helicopters of a possible safety issue with the main rotor pitch link assemblies. This CAN is re-issued at revision 1 to raise awareness of the instructions in Guimbal SB 21-006B, which provides inspections and preventative maintenance actions related to the safety concern identified in this CAN.

This CAN is prompted by CAA awareness of several cargo hooks in New Zealand being damaged due to torsional loads. Loads attached to a cargo hook with a spreader bar (e.g. a fertilizer bucket) may cause the cargo hook to be subjected to high torsional loads which can damage the cargo hook. To ensure continued airworthiness of the hook, additional inspections, certain on-condition repairs, and/or appropriate replacement actions have been added to the manufacturers CMM. Refer to Onboard Systems CMM 122-015-00 for the new/additional inspections required for cargo hooks used for torsional load applications.
