How often must an emergency locator transmitter (ELT) be inspected?

The frequency of inspection for an emergency locator transmitter (ELT) is mandated by regulations to ensure its reliability in an emergency situation. An ELT must be inspected every 12 months. This annual inspection requirement is crucial because it helps verify that the transmitter is functioning properly and will operate as expected if activated in an emergency. Regular inspections include checking the battery status, ensuring that the ELT is securely mounted and properly configured, and confirming that it meets the operational and maintenance specifications set by aviation authorities.

This annual check helps ensure that pilots can depend on their ELT to provide a distress signal if needed, thereby increasing the chances of a successful rescue following an aircraft accident.
