Plain English Summary

2/10 complexity

This directive requires fitting a turbine-blade containment ring, per Airesearch Service Bulletin No. 49-1790, to certain Airesearch APU models/serial ranges before those APUs are reinstalled in aircraft after reconditioning or hot-end repair occurring after 30 November 1971. It affects aircraft owners/operators and their maintenance providers, creating a mandatory pre-installation task that adds parts, labour and scheduling/downtime costs; CASA enforces compliance under the airworthiness regime.
