             This Amendment becomes effective on 18 June 2008.
Background:  The ANAC has received reports that some "caution" messages issued by the FGCS are not displayed on aircraft equipped with EPIC software load 17.3, 17.4, 17.5, 17.6 or 17.7.  Therefore, following a possible failure on one FGCS channel during a given flight, such a failure condition will remain undetected or latent in subsequent flights.  If another failure occurs on the second FGCS channel, the result may be a command hard-over by the autopilot.
             Since this condition may affect the safety of the aeroplane, the original issue of this Directive required the repetitive functional testing of the FGCS.
             Amendment 1 continued the repetitive inspection requirement until software load version 19.3 or higher was installed.
             Amendment 2, whilst continuing the initial repetitive inspection requirement and the additional terminating requirement, introduced by Amendment 1, changed the applicability of the Directive following similar action by the Brazilian ANAC.
             Amendment 3, whilst continuing the initial repetitive inspection requirement and the additional terminating requirement introduced by Amendment 1, clarified how higher load versions of the Primus EPIC software may be installed.
             This Amendment continues the repetitive inspection requirement but extends the terminating action date by 12 months.
             The original issue of this Directive became effective on 4 April 2007.
             Amendment 1 became effective on 19 October 2007.
             Amendment 2 became effective on 2 November 2007.
             Amendment 3 became effective on 5 June 2008.
