Airworthiness Directives; Avidyne Corporation Integrated Flight Displays

We are adopting a new airworthiness directive (AD) for Avidyne Corporation (Avidyne) Integrated Flight Displays (IFDs) part number (P/ N) 700-00083-() loaded with software release 9.3.1.0 or earlier release (referred to as Model R9--10 inch), P/N 700-00171-() loaded with software release 9.2.5.0 or earlier release (referred to as Model R9-- 12 inch), and P/N 700-00182-() loaded with software release 10.0.3.0 or earlier release (referred to as Model IFD540). This emergency AD was sent previously to all known U.S. owners and operators of all aircraft that incorporate the above referenced Avidyne IFDs. This AD requires incorporating an operational limitation into the Limitations section of the airplane flight manual (AFM) or airplane flight manual supplement (AFMS). This AD was prompted by reports of Avidyne IFDs displaying incorrect course deviation indication information during GPS approaches (incorrect display of lateral deviations). We are issuing this AD to correct the unsafe condition on these products.
