<p>Australia's Civil Aviation Safety Authority (CASA) is seeking comments on a draft advisory circular (AC) update on objects and structures that affect aircraft safety. Draft multi-part AC 139.E-01 and AC 175.E-02 V2.0&nbsp;is intended to assist&nbsp;entities&nbsp;involved in the planning, approval, erection, extension, or dismantling of objects and structures. The guidance in this draft AC addresses&nbsp;aviation risks and regulatory frameworks, and the reporting of objects and structures posing a potential hazard. CASA is&nbsp;seeking feedback on whether the&nbsp;content and structure of the guidance is clear and sufficient. Comments are due by Oct. 1, 2025.</p>
