These are estimated installation costs associated with the new 406 MHz ELTs. Most aircraft built in the last 15 years already have a remote activation switch (in the cockpit) for the ELT. In most cases, this wiring can be used for the remote switch (which is required by law) for the new 406MHz ELT. In older aircraft (typically older than 15 years), a remote switch will need to be installed. An average repair shop charges $80.00/hour. If the aircraft has a remote switch installed already, the installation time is 3-6 hours ($240-$480). If the aircraft does not have a remote switch installed, the installation time is 5-15 hours ($400-$1200).
