EASA SIB SW-13-08
Aspen Avionics EFD1000 and EFD500 Multifunction Displays
Summary
The FAA Special Airworthiness Information Bulletin SAIB: SW-13-08 addresses an issue with Aspen Avionics EFD1000 and EFD500 Multifunction Displays (MFD) where the displays may unintentionally reset when processing a large number of Temporary Flight Restrictions (TFRs). This bulletin applies to aircraft equipped with these Aspen Avionics MFDs connected to sources receiving TFR data, such as XM Satellite receivers. The primary flight displays are not affected by this reset issue.
What Changed
This bulletin introduces awareness of a software-related reset issue in Aspen Avionics EFD1000 and EFD500 MFDs triggered by receiving over 100 TFRs while displaying moving maps or TFR pages. It recommends updating the avionics software to version 2.6 or later and using the latest approved flight manual supplement to mitigate the issue. No mandatory airworthiness directive action is required at this time.
Why It Matters
This information is important for aviation professionals because the MFD reset can cause temporary loss of display and autopilot disconnection, potentially impacting situational awareness and autopilot functionality during flight. Understanding this issue helps operators and maintenance personnel manage risks and maintain safe operation of affected aircraft. Compliance with recommended software updates ensures improved reliability of avionics systems.
What To Do
Owners and operators should update the Aspen Avionics EFD1000 and EFD500 software to version 2.6 or later as approved by the FAA, following Aspen Service Bulletin SB2012-05. They should also ensure use of revision N or later of the approved flight manual supplement and familiarize themselves with troubleshooting procedures in section 3.15 of the supplement. No specific compliance deadline is stated.
