Plain English Summary

2/10 complexity

This instrument revokes a batch of existing Airworthiness Directives (ADs) for DH114 (Heron) series aeroplanes and re‑issues each AD as a separate, unchanged instrument. It is made by a Civil Aviation Safety Authority delegate under subregulation 39.001(1).

Mechanically, the directive does not change technical requirements: aircraft owners and operators remain obliged to comply with the same ADs. The measure mainly alters administrative form, preserving existing compliance obligations while shifting record‑keeping to the reissued individual instruments.
