AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.001(1) of CASR 1998.  The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Dassault Aviation Falcon 2000 Series Aeroplanes
AD/F2000/10  Ice and Rain Protection - Outboard  5/2006
             Leading Edge Slats

Applicability:  Falcon 2000 aircraft S/N 1 to 223 and Falcon 2000EX S/N 1 to 69.
Requirement:       1. Inspect the outboard slats in accordance with the instructions detailed in
                   F2000-331, or F2000EX-91 as is applicable.

                   2. For F2000 and F2000EX which have incorrect slats installed:

                   Repair the manifold according to the instructions detailed in F2000-331, or F2000EX-91 as is applicable.

                This is a terminating action for this AD for the relevant aircraft.

                Note:  EASA AD 2006-0037dated 1 February 2006 refers.
Compliance:        1. Within 330 Flight Hours (FH) or 7 months, whichever comes first, following the effective date of this AD.

                   2. Before further flight.
                This Airworthiness Directive becomes effective on 11 May 2006.
Background:     Wings of MF5O, MF900, F900EX, F2000 and F2000EX are aerodynamically identical on many points.  Outboard slats on all 5 models have the same external shape and are mechanically interchangeable.  However, hot air anti-icing systems on MF5O are different from those on MF900 I F900EX I F2000 and F2000EX aeroplanes; therefore the slats are functionally not equivalent.

                It has been found, during an internal review, that interchangeability of outboard slats between MF5O and MF900 I F900EX or F2000 / F2000EX had been erroneously authorized in some limited cases.  The outboard slats P/N identification plates also appear to be misleading.  Exchanges occurring after delivery of the aircraft may have led to installation of outboard slats of the type not adapted to the aircraft model.  Repairs may have led to installation of anti-icing manifolds ("piccolos tubes") of a type not adapted to the aircraft model.

                This may jeopardize the aircraft, by modifying its anti-icing performance.

   The purpose of this Airworthiness Directive (AD) is to check that all aircraft are fitted with the correct outboard slats, and to correct, either by an exchange or a repair, any discrepancy encountered.
