AD Proposed for Eclipse 500 EFIS

 - August 1, 2010, 9:36 AM

A proposed Airworthiness Directive for Eclipse 500s would require changes to the electronic flight information system and the airplane flight manuals. The proposed 

AD stems from reports of uncommanded changes to the communications radio frequency, altitude preselect and/or transponder codes. The FAA said the AD would “correct faulty integration of hardware and software” on Eclipses.
