§44712 Emergency Locator Transmitters

Last updated Sep 22, 2026|Official source

Summary

Fixed-wing powered civil aircraft used in air commerce must have an emergency locator transmitter (ELT) installed. Before January 1, 2002, several kinds of planes did not have to carry an ELT, including turbojet planes and various aircraft used for scheduled airline flights, short-range training (inside 50 miles of the home airport), testing, manufacturing, delivery, agricultural spraying, FAA-approved research and development, demonstrations or training, air racing, market surveys, and single-seat planes. Starting January 1, 2002, most of those same exceptions still apply, but turbojet planes are not listed and there is an added exception for aircraft with a maximum payload over 18,000 pounds when used in air transportation. The FAA Administrator can delay switching to the post-2001 rules for up to 2 years to allow a safe transition or meet safety goals. An aircraft satisfies the rule if its ELT sends signals on 121.5/243 MHz or 406 MHz, or uses other equipment the Secretary approves. The FAA must also make rules about when a plane may operate without an ELT because it was removed for inspection, repair, change, or replacement.
