- 0 005

Date: 14 January 201 5

Note: This Airworthiness Directive (AD) is issued by EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation

.
This AD is issued in accordance with EU 748/2012, Part 21.A.3B. In accordan ce with EU 1321/2014 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may ope rate an aircraft to which an AD applies, except in accordance with the requirements of that AD, unless otherwise specified by the Agency [EU 1321/2014 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption]

Manufacturer(s): Dassault Aviation

Applicability: Falcon 2000EX aeroplanes

, all serial numbers (s/n), except aeroplanes with Dassault Aviation production modification (mod) M3254 , or modified in service by Dassault Aviation S ervice Bulletin (S B ) F2000EX

, Falcon 900EX aeroplanes

, all s/n

, except aeroplanes with “EASy II ” “ 2nd certification” avionics

, which are defined as: modified in production with Dassault Aviation mod M5595

, or modified in service with Dassault Aviation SB F900EX

- 400 at Revision 3 (or any later revision) or with Dassault Aviation SB F900EX

- 4 14 at Revision 4 (or any later revision)

. Note: Commercial versions “ F2000LXS” and “F2000S” are also not affected by the requirements of this AD

, as these are fitted with “ EASy II ” avionics

.

Reason: During a flight test on a development aeroplane

, it was found that the y aw d amper (YD) working on the take

- off roll can increase the Minimum Control Speed on Ground (Vmcg ). A review of the certification data of the affected aeroplanes shows that Vmcg values published in the Airplane Flight Manuals (AFM) have been determined without YD

. This condition, if not corrected, could result

, in case of an engine failure occurring d uring the roll acceleration, in reduced lateral control of the aeroplane

. To address this condition, Dassault Aviation developed Change Proposals (CP)E ASA AD No.: 2015
