Airworthiness Directive 2020-16-08, Amendment 39-21192 Aspen Avionics Inc

Print Email

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Aspen Avionics, Inc., Evolution Flight Display (EFD) EFD1000 Emergency Backup Display, EFD1000 Multi- Function Display, and EFD1000 Primary Flight Display systems installed on various airplanes. This AD imposes operating restrictions on these display systems by revising the Limitations section of the airplane flight manual (AFM). This AD was prompted by an automatic reset occurring when the display internal monitor detects a potential fault, causing intermittent loss of airspeed, attitude, and altitude information during flight. The FAA is issuing this AD to address the unsafe condition on these products.

 

DATES: This AD is effective August 17, 2020.

The FAA must receive comments on this AD by September 14, 2020.
