FAA mandates upgrade to Eclipse avionics

“Uncommanded changes” to radio frequencies, altitudes and transponder codes by the electronic flight information systems in some Eclipse jets have been reported, leading to an Airworthiness Directive issued this week that mandates upgrades to the system, according to a report at AVweb, which notes the AD affects approximately 168 aircraft in the fleet. Depending what kind of system the airplane has, the fix could cost as little as $770 to $1,670, or as much as $249,950.
