An ELT is a device that broadcasts a distress signal if a plane crashes.\n\n**The specific problem:**\nThe antenna's coaxial connector (the plug that connects the antenna to the emergency beacon) can come loose. If it disconnects and touches exposed electrical terminals — like a battery relay — it could cause a short circuit or fire.\n\n**What must be done:**\n- Check the connector is firmly attached and clicks into its locked (detent) position\n- Coil up any extra antenna cable and tie it down so that even if the connector comes loose, it can't swing around and touch live electrical parts\n\n**Who it affects:**\nOwners and operators of:\n- Cessna 182 models (including 182A through 182Q and R182 variants)\n- Wren 460 series aircraft\n- **Only if** they have a Leigh Sharc 7 or Dorne & Margolin DME LT6 emergency beacon installed using Cessna's standard US factory installation drawings\n\n**Why it matters:**\nThis is an urgent safety fix. A loose antenna connector touching electrical terminals could cause a fire in the aircraft. The word \"Forthwith\" means do it immediately — no grace period.\n\n**Key takeaway:** If you own one of these planes with one of these specific emergency beacons, you need to check the antenna connection right now and secure any loose cable to prevent a potential fire hazard."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"Within this directive itself the scope is narrowly defined: it applies only to Cessna 182/182A–182Q and R182 Series aeroplanes fitted with either a Leigh Sharc 7 or a Dorne & Margolin DME LT6 ELT installed in accordance with Cessna standard installation drawings (USA installations) (Applicability).
