Flap hinge bolts are critical hardware that attach the flaps — the movable surfaces on the wings that help slow the aircraft during landing.\n\n**What it is now:** This directive has been **removed from active status** because no BAe 125 aircraft are currently registered in Australia. The \"DM\" marking indicates it is **deleted/made inactive**.\n\n**Why it matters:** Airworthiness Directives are legally binding safety instructions. When an aircraft type leaves the Australian register, related ADs are typically withdrawn to keep the regulatory framework current and uncluttered. If a BAe 125 were re-registered in Australia, CASA would need to reactivate or replace this directive."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The AD originally required a modification to a flap hinge bolt on BAe 125 series aeroplanes (AD/HS 125/69).
