The original directive (from September 1987) likely required inspection, modification, or replacement of these parts due to a safety concern.\n\n**Why it matters now:** **This directive has been cancelled.** The entire contents have been removed from CASA's active list because no BAe 125 aircraft are currently registered in Australia. If none of these planes fly here anymore, there's no need to keep enforcing the safety rule.\n\n**Bottom line:** This is a dead document — a placeholder showing where a safety rule used to be, kept for historical records but no longer legally binding on anyone."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The AD was originally recorded as applying to British Aerospace BAe 125 series aeroplanes and concerned flight deck side console louvers and adaptors (AD/HS 125/90 Amdt 1).
