CASA is tidying up its legislative framework by converting old-style Airworthiness Directives into the newer \"separate instrument\" format required by the Civil Aviation Safety Regulations 1998. **The actual safety requirements haven't changed** — the rules themselves stay identical. This ensures continuity of safety standards while updating the legal machinery behind them."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"Scope has not changed.
