Applicability:  Falcon 2000EX aeroplanes, serial numbers 06, 28 to 86 inclusive, and 88; without Dassault Aviation Falcon Service Bulletin (SB) F2000EX-100 dated 30 August 2006 or later Revision approved by the European Aviation Safety Agency (EASA) implemented (ie still in EASy Step 2 configuration).
Requirement:       1. Perform a software check using a dedicated software tool named "Flash Integrity Check" (FLICK) in accordance with the accomplishment instructions of Dassault Aviation Falcon SB F2000EX-120 dated 7 September 2006 or later Revision approved by the EASA.
                   2. Make a temporary amendment to Chapter 5-40 of the Aircraft Maintenance Manual (AMM) to indicate that the MP 45-403 "Software modules integrity check" is to be accomplished at 40 day intervals.
                Note 1:  To record the temporary inspection schedule, a copy of this Directive may be included in of the AMM as a temporary change.
                   3. Modify the aircraft in accordance with the accomplishment instructions of SB F2000EX-100 (modification M2656) or later Revision approved by the EASA.
                This is considered to be a terminating action for the temporary repetitive inspection requirements introduced by the Requirement 2 AMM amendment and the temporary amendment to the AMM may be removed.

                For Requirement 4 - After each operational software loading.

             This Airworthiness Directive becomes effective on 28 February 2007.
Background:  EASA has advised that during an internal review, it was discovered that some software integrity checks were not fully implemented in modules of the Honeywell EPIC avionics, as used in Falcon EASy aircraft.
             Consequently, the continuing integrity of the modules' software cannot
