Plain English Summary

3/10 complexity

This instrument, signed by a Civil Aviation Safety Authority delegate under subregulation 39.001(1), revokes a package of Airworthiness Directives for AlliedSignal (Lycoming) ALF502 and LF507 turbine engines and remakes each as a separate directive in the same form. It affects aircraft operators, maintenance organisations and parts suppliers who must follow the listed directives. Mechanically, the delegate replaces the cancelled instruments with identically worded separate ADs; the CASA delegate decides, and operators/maintainers bear the compliance costs of inspections, limits or parts actions required by those ADs.
