Plain English Summary

3/10 complexity

This instrument revokes a list of Airworthiness Directives for Douglas DC‑4 series aeroplanes and reissues each Directive as a separate, identical instrument. The CASA delegate acts under subregulation 39.001(1) to perform the revocation and remaking (see Schedule 1).

Owners, operators and maintenance organisations remain subject to the same mandatory safety requirements and bear any compliance and maintenance costs. The change is administrative: it preserves existing obligations while converting each Directive into a standalone legal instrument.
