If this panel can't open properly during a rapid decompression or fire, it could endanger passengers and crew.\n\n**What must be done:**\nAircraft operators must follow the technical instructions in **Brazil CTA AD 91-10-01** (Brazil's equivalent safety order, referenced as Amendment 39-688). Embraer Service Bulletin 120-025-0163 provides additional guidance.\n\n**Who it affects:**\nOwners and operators of the 15 specific Embraer EMB-120 aircraft listed by serial number.\n\n**Why it matters:**\nThis prevents a potentially dangerous situation where emergency pressure relief could fail, protecting passengers and crew during in-flight emergencies.
