2 Background

Avidyne originally issued Service Alert SA- 05-001 informing you of several field reports of PFDs displaying incorrect attitude and heading information. These occurrences were accompanied by a “CROSSCHECK ATTITUDE” alert annunciation within approximately 45 seconds after initiation of the condition.

In response to the Service Alert, we issued SAIB CE-06-07 to advise Cirrus owners of the potential problem and recommend increased attention to standard and emergency operating procedures when flying in Instrument Metrological Conditions (IMC).

SAIB CE-06-07 advised Cirrus owners that Avidyne was working to find the cause of the problem, and that once the problem was better understood; we might take further airworthiness action in the future. This SAIB is the follow-up action. Recommendation

Please review the list in Table 1 to determine if your airplane manufacturer, model, and serial number may have one of the Avidyne part numbers covered by Service Alert SA-06- 003. If your airplane is contained within the list, and an Avidyne PFD is installed in your airplane, you should determine the PFD part number and serial number. Then call Avidyne at 1-888-723-7592 to determine if your PFD needs to be scheduled to have the modification accomplished or if the modification has already been performed during previous maintenance. If your PFD is eligible for the modification, as described in Avidyne Service Alert SA-06-003, we highly recommend you do the modification.
