If you don't comply, you can't fly the aircraft legally. This instrument doesn't change the actual safety requirements — it just formally revokes the old versions and re-makes them as separate legal instruments. This is likely an administrative tidy-up to ensure each directive stands alone for easier reference and enforcement."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The instrument does not change the substantive scope or technical requirements of the affected Airworthiness Directives.
