Plain English Summary

3/10 complexity

This instrument revokes a set of Airworthiness Directives (ADs) that apply to General Electric CT7 series turbine engines and reissues each AD as a separate, identical instrument. It is made by a Civil Aviation Safety Authority delegate under subregulation 39.001(1).

Aircraft operators, maintenance organisations and parts suppliers using CT7 engines must continue to follow the reissued ADs and bear the usual compliance costs (inspections, parts replacement, record‑keeping). The stated change is administrative: texts are remade in the same form rather than introducing new technical requirements (see Schedule 1 and accompanying note).
