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.

The Artex C406 provides an integrated ELT to navigation interface and transmits latitude and longitude position information with an accuracy of 100 meters. The unit operates on 121.5-, 243- and 406-MHz frequencies and features a five-year battery life. Certifications include TSO C126 and ETSO 2C126 and the unit is approved by Cospas/Sarsat and Transport and Industry Canada.

Sierra’s installation includes the ELT unit, high-speed blade antenna and wiring, as well as required removal and reinstallation of cabin interior components. Sierra’s 2010 installed pricing for the Artex C406 unit starts at $8,500 for a basic installation or $12,000 installed with GPS position broadcast capability.
