Re: New ELT 406 mhz
As of Feb. 1, 2009, satellites will stop monitoring 121.5 MHz, one of the emergency frequencies for ELTs. This has sparked concern in the aviation industry and has caused Transport Canada to propose a rule requiring aircraft flying in Canada to be equipped with a 406-MHz ELT. The FAA has not given any indication that it will mandate a switch to the 406-MHz ELT. So, at the present time those of us in the USA will not be required to install new 406 MHz ELT's. It is still legal to purchase and install a 121.5 MHz ELT in your aircraft (note: we are talking Part 91 GA aircraft operating in the USA) as long as the ELT meets TSO C91a certs. A review of the ELT rules (FAR 91.207) and TSO C91a would be wise if you are in need of an ELT. And don't count on your local avonics shop to be up on the latest requirements. During the last year I've seen a local high dollar shop: (1) install a new ELT and not install the required remote panel (2) replace an ELT battery with one that had an expiration date 3 months in the future (3) inform a customer that a 406 MHz ELT would be required in 2009. Everyone needs to become familiar with the basics so when annual time arrives I don't have to inform you that your ELT installation isn't legal or that your ELT battery has been out of date for 9 months.
