EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0061

Date: 11 March 2014

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].

Design Approval Holder’s Name:

Type/Model designation(s):

Falcon 900, Falcon 900EX, Falcon 2000 and

TCDS Number: EASA.A.062 and EASA.A.008

Foreign AD: Not applicable

Supersedure: None

ATA 25

Equipment / Furnishings – Cockpit Seat / Locking Springs –

Replacement

Manufacturer(s): Dassault Aviation

Applicability: Falcon 900, Falcon 900EX, Falcon 2000 and F2000EX aeroplanes which are 

equipped with SICMA 132-series or 142-series pilot and co-pilot seats.

Reason: During take-off at rotation, a co-pilot reported to slide aft on his seat.

The results of the investigations concluded that one spring of the seat locking 

system was broken and the other was weak. The root cause was determined to 

be fatigue wear. As springs accumulate cycles in service, they become 

increasingly exposed to the risk of unnoticed degradation or rupture. 

This condition, if not corrected, could cause the pilot or the co-pilot to lose 

contact with the controls, leading to an inadvertent input on the flight control 

commands during take-off or climb, possibly resulting in loss of control of the 

aeroplane.

To address this unsafe condition, it was decided to require replacement of the 

affected seat springs for older aeroplanes and for newer aeroplanes; this task 

has been embodied in the aeroplane maintenance manual.

For the reasons described above, this AD requires replacement of the springs

installed on the pilot and co-pilot seats with serviceable springs.
