How often are emergency locator transmitters required to be inspected?

Emergency locator transmitters (ELTs) are crucial devices used in aviation to help locate aircraft that have been involved in an accident or have gone missing. The regulations set forth by the Federal Aviation Administration (FAA) dictate that ELTs must be inspected every 12 months to ensure that they are functional and ready for use in an emergency situation.

This annual inspection includes checking the operation of the device, verifying the signal transmission capabilities, and ensuring that the battery is still viable and meets the necessary requirements. For instance, batteries typically need to be replaced after a specified period, usually 24 months, to prevent failure.

Regular inspections every 12 months help maintain operational readiness and compliance with safety regulations, increasing the chances of successful search and rescue operations when needed. Other options may reflect different maintenance practices for other aviation equipment, but for ELTs, the 12-month interval is the established standard.
