If you don't comply, you can't fly the aircraft.\n- This addresses an \"unsafe condition\" (the exact nature isn't detailed in this excerpt, but ADs are only issued when there's a genuine safety risk — typically electrical faults, fire hazards, or interference with critical systems)\n- The directive mandates specific actions, timing, and compliance methods\n\n**Key point:** This isn't optional maintenance advice — it's a legal requirement backed by aviation safety law (specifically Civil Aviation Regulation 39.1(1))."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The AD as presented applies to Model 747SP aeroplanes modified by FAA STC ST09097AC‑D.
