CASA periodically \"remakes\" older airworthiness directives to ensure they remain legally valid and properly formatted under current regulations. The note explicitly states the directive is being remade \"in exactly the same form\" — meaning **no substantive changes** to the safety requirements.\n\nThe technical requirement (replacing certain bolts on propeller spinners) remains unchanged. This is about keeping the paperwork current, not changing safety standards."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument does not change the substantive scope of the listed Airworthiness Directive.
