## EASA AIRWORTHINESS DIRECTIVE

AD No.: 2010-0029R1

Date: 25 November 2010

Note: This Airworthiness Directive (AD) is issued b y EASA, acting in accordance with Regulation (EC) No 216/2008 on behalf of the Europe an 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 EC 1702/2003, Part 21A.3B. In accordance with EC 2042/2003 Annex I, Part M.A.301, the continuing airworthiness of an aircraft shall be en sured by accomplishing any applicable ADs. Conseque ntly, no person may operate an aircraft to which an Airworthiness Direc tive applies, except in accordance with the require ments of that Airworthiness Directive unless otherwise specified by the Agency [EC 2042/2003 Annex I, Part M.A.303] or agreed with the Authority of the State of Registry [EC 216/2008, Article 14(4) exemption].

Foreign AD: Not Applicable

Revision: This AD revises EASA AD 201 0-0029 dated 01 March 2010.



### ATA 24 & 29 Electrical Power & Hydraulic Power – Electrical Wir ings &

Hydraulic Lines Routing – Modification(s)

Manufacturer(s): DASSAULT AVIATION

Applicability: Falcon 7X aeroplanes serial numbers 2 to 22 inclusive, 24 to 26 inclusive, 29, 30, 32 and all other serial numbers except those on which modifications M964, M937, M976, M1007 or M1036, M1020 or M1037 an d M1022 have all been implemented.

Reason: On some Falcon 7X aeroplanes, it has been determine d potential low clearance between electrical wiring or hydraulic pi pe and nearby structure. Although no in service incident has been reported, there is no certainty that the minimum clearances would be maintained over tim e. In the worst case, interference or contact with structure might occur and lead to electrical short circuits or fluid leakage, potentially resulting in loss of several functions essential for safe flight. Dassault Aviation has developed two Service Bulleti ns (SB) that provide corrective actions to ensure the minimum required c learance, as well as adequate protection between hydraulic pipe (SB n° 0 92) and electrical wiring (SB n° 006) and the aeroplane structure. This AD requires the implementation of both SBs on the affected aeroplanes. Since issuance of EASA AD 2010-0029, Dassault Aviat ion has developed modifications M1036 and M1037. M1036 is equivalent to M1007 while M1037 is equivalent to M1020. These modifications are emb odied during production on new aeroplanes.EASA AD No : 2010-0029R1

EASA Form 112 Page 2/2 This AD has been revised to exclude from the AD app licability the aeroplanes on which those modifications are embodied.

Effective Date: Revision 1: 09 December 2010. Original issue: 15 March 2010.
