EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0128

Date: 17 June 2013

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 accordance with EC 2042/2003 Annex I, Part M.A.301, the 

continuing airworthiness of an aircraft shall be ensured by accomplishing any applicable ADs. Consequently, no person may operate an 

aircraft to which an AD applies, except in accordance with the requirements of that AD, 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].

Type Approval Holder’s Name :

DASSAULT AVIATION

Type/Model designation(s) :

Falcon 7X aeroplanes

TCDS Number : EASA.A.062

Foreign AD : Not Applicable

Supersedure : None

ATA 32 Landing Gear – Nose Wheel Steering – Airplane Flight Manual 

Change

Manufacturer(s): DASSAULT AVIATION

Applicability: Falcon 7X aeroplanes, all Manufacturer Serial Numbers.

Reason: A Falcon 7X aeroplane recently experienced a runway excursion. The results of 

the subsequent technical investigations accomplished by Dassault Aviation 

identified a failure of the Nose Landing Gear position feed-back assembly, due 

to an incorrect angle signal resulting in un-commanded nose wheel deflection 

which could not be countered by the pilot.

This condition, if not detected and corrected, could lead to further similar events, 

which could result in damage to the aeroplane.

To address this potential unsafe condition, pending the development of an 

assembly with improved design, Dassault Aviation published an operational 

procedure, for checking the condition of the nose wheel steering position feedback. This procedure has been incorporated into the applicable electronic 

checklist.

For the reasons described above, this AD requires incorporation of the new 

procedure into the Airplane Flight Manual (AFM) and an update of the Electronic 

Check List (ECL).

This AD is considered to be an interim action and further AD action may follow.

and Compliance 

Time(s):

Required as indicated, unless previously accomplished:

Within 30 days after the effective date of this AD, accomplish the following 

actions:

(1) Amend the applicable AFM DGT 105608 to incorporate the operational 

procedure as specified in Dassault Aviation Change Proposal (CP) 076.

This can be accomplished by inserting a copy of CP076 into the applicable 

AFM.

Inform all flight crews concerning this AFM change and, thereafter, operate 

the aeroplane accordingly.

(2) Update the ECL to the version specified in Table 1 of this AD, as 

applicable, depending on the avionics standard installed on the aeroplane.

Table 1 – ECL update
