Plain English Summary

3/10 complexity

This instrument (made under subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998) revokes a list of Airworthiness Directives (ADs) for Enstrom F‑28 series helicopters and re‑issues each as a separate, identical instrument. The delegate states each re‑made AD matches the latest published edition.

Owners, operators and maintenance organisations of Enstrom F‑28 helicopters are affected because the ADs set the continuing mandatory safety and maintenance requirements they must follow; the measure preserves existing obligations while transferring them into freshly issued legal instruments.
