In this document, the Federal Communications Commission (Commission or FCC) adopts a rule that prohibits the certification, and after a six-month transition period, the manufacture, importation, or sale of 121.5 MHz Emergency Locator Transmitters (ELTs), but declines to prohibit the use of 121.5 MHz ELTs. By accelerating the transition from 121.5 MHz ELTs to 406 MHz ELTs, this rule change will enhance the ability of search and rescue personnel to locate and bring aid to the victims of plane crashes.
