§44712 Emergency locator transmitters

Last updated Apr 6, 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, that rule did not apply to several types of aircraft, such as turbojet planes, scheduled airline flights, short training flights within 50 miles of the home airport, test or manufacturing flights, agricultural spraying, FAA-certified research flights, flights for compliance checks, training, shows, racing, market surveys, and single-seat planes. After January 1, 2002, most of the same exceptions still apply and there is an added exception for planes with a maximum payload over 18,000 pounds. The FAA Administrator can keep the older rules in place for up to 2 years after January 1, 2002 to allow a safe transition or meet other safety goals. An aircraft meets the rule if its ELT transmits on 121.5 or 243 megahertz, or 406 megahertz, or if it has other equipment approved by the Secretary. The FAA must create rules for when a plane may fly if its ELT has been removed for inspection, repair, alteration, or replacement.
