FAA Warns Of Avidyne Glitch
Owners of Cirrus, Columbia and Piper airplanes with Avidyne primary flight displays were advised by the FAA on Tuesday of a possible glitch in the system. The FAA Special Airworthiness Information Bulletin said a modification is available to eliminate the possibility that the system will display misleading attitude and heading information. Avidyne has already issued a Service Alert to owners. The FAA recommends that pilots using the Avidyne panel should pay increased attention to standard and emergency operating procedures when flying in instrument metrological conditions. Avidyne can modify the units to prevent the problem, and owners should call Avidyne to ensure that modification is completed, the FAA said. The action is not mandatory, but the FAA says, "If your PFD is eligible ... we highly recommend you do the modification."
