This meant crew or passengers needed excessive force to release the cover during an emergency, which could slow down or prevent the door from opening properly — a serious safety risk during an emergency evacuation.\n\n**What must be done:**\nOperators must follow the instructions in **BAe Service Bulletin 25-58-35069A** (a technical repair notice from the manufacturer) to correct the latch tension.\n\n**Who it affects:**\nAnyone who owns, operates, or maintains the specified BAe 146 aircraft models in Australia.\n\n**Why it matters:**\nEmergency evacuation slides must deploy quickly and reliably.
