The FAA has issued a supplemental type certificate (STC) to Sierra Industries for the installation of the Artex C406 (406 MHz) emergency locator transmitter on the Cessna Citation 500, 501, 550, 551, S550 and 560. The STC provides a solution
for operators to update their emergency transmitters to current standards.
Early last year, U.S. emergency distress satellites ceased monitoring the older 121.5-MHz emergency frequency band in favor of the newly established and more accurate 406-MHz standard. Although 406-MHz ELTs are not yet required in the U.S., numerous other countries, including Canada, Mexico and the European Union, have established or are in the process of implementing the 406-MHz standard.
