For Requirement 4 - After 31 March 2007.
             This Amendment becomes effective on 7 March 2007.
Background:  The European Aviation Safety Agency (EASA) has been advised by the engine manufacturer that over a period of time, the alteration of one ECU electronic component can cause a rapid uncontrolled power increase.  Several occurrences have already been reported during engine start or during engine warm-up.  This could result in loss of control of the aircraft.
             This original issue of this Directive required the aircraft to be inspected to determine the ECU S/N and, if necessary, the replacement of the ECU.  The Directive also allows a one time flight to a location capable of effecting replacement of the ECU.  EASA has now advised that this was a temporary corrective action.
             This Amendment clarifies the applicability by including a part number range and advises that the affected engine may also be installed on Reims F182 aeroplanes.  At the same time, the Amendment identifies a replacement ECU part number and requires the replacement of all affected ECUs, irrespective of their serial number.  Additionally, the Amendment prohibits the fitment of an affected ECU as a spare after 31 March 2007.
             The original issue of this Directive became effective on 17 October 2006.
