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.

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 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.

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.
