If it fails, the fuel tank could detach during flight — a catastrophic risk. Airworthiness Directives are legally binding; operators must comply or ground the aircraft.\n\n**Current status:**\nThe directive's contents have been **removed from the active register** because no BAe 125 aircraft are currently registered in Australia.
