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.

Latest continuing airworthiness notices

The purpose of this Continuing Airworthiness Notice (CAN) is to advise aviation participants of the current situation regarding aircraft operations for maintenance under COVID-19 restrictions. Revision 5 of this CAN is raised to address the change in Alert Level advice for the Auckland area announced 7 October 2021, and to outline the remaining restriction on flying non-essential aircraft under Alert Level 3.

The purpose of this Continuing Airworthiness Notice (CAN) is to inform aircraft operators and maintenance providers that the CAA recently became aware of a clutch assembly defect (i.e. spalling damage to a C166-5 shaft). There have been several mid-life sprag failures in R44 helicopters over the past 15 years. In response to these failures the CAA issued DCA/R44/23B to inspect the clutch oil for contamination every 500 hours TIS. The damaged shaft was not found as a result of an inspection in accordance with DCA/R44/23B and there were no sprags found damaged or broken.

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 Continuing Airworthiness Notice (CAN) is issued to bring attention to an issue reported to the CAA recently, where MS21042L3 nuts appeared to lose their self-locking function during installation.

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.

This Continuing Airworthiness Notice (CAN) is issued to advise users of the above mentioned Garmin GTN Xi products that these units are sending erroneous ADS-B OUT data. This issue is described in Garmin Service Advisory 20140 revision B, dated 12 January 2021.

This Continuing Airworthiness Notice (CAN) is issued to advise Jabiru engine operators of the safety recommendations identified by the Australian Transport Safety Bureau (ATSB) with an investigation of a propeller loss on a Jabiru J430 aircraft in Austral
