EASA AIRWORTHINESS DIRECTIVE

AD No.: 2014-0021

Date: 20 January 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:

DASSAULT AVIATION

Type/Model designation(s):

Fan Jet Falcon aeroplanes

TCDS Number: DGAC France 103

Foreign AD: Not applicable

Supersedure: None

ATA 05 Time Limits and Maintenance Checks – Airworthiness Limitations –

Amendment / Implementation

Manufacturer(s): DASSAULT AVIATION

Applicability: Fan Jet Falcon aeroplanes, all serial numbers 

Reason: The airworthiness limitations and maintenance requirements for the Fan Jet 

Falcon type design are included in Dassault Aviation Falcon 20 (F20) Aircraft 

Maintenance Manual (AMM) chapter 5-40 and are approved by the European

Aviation Safety Agency (EASA). EASA issued AD 2008-0221 to require 

accomplishment of the maintenance tasks, and implementation of the 

airworthiness limitations, as specified in Dassault Aviation F20 AMM chapter 5-

40 at revision 13.

Since that AD was issued, Dassault Aviation issued F20 AMM chapter 5-40 at 

revision 15, which introduces new or more restrictive maintenance requirements 

and/or airworthiness limitations.

Dassault Aviation AMM chapter 5-40 revision 15 contains among other changes 

the following requirements:

- Specific instructions applicable to F20GF (serial number 397);

- Check of overpressure tightness on pressurization control regulating valves;

- Check of overpressure relief valve vacuum supply lines.

A new document reference number which comes with DGT 131028 revision 15

is replacing DMD11755.

The maintenance tasks and airworthiness limitations, as specified in the F20

AMM chapter 5-40, have been identified as mandatory actions for continued 

airworthiness of the Fan Jet Falcon type design. Failure to comply with AMM 

chapter 5-40 at revision 15 might constitute an unsafe condition.

For the reasons described above, this AD requires implementation of the 

maintenance tasks and airworthiness limitations, as specified in Dassault 

Aviation F20 AMM chapter 5-40 at revision 15.

in accordance with the approved maintenance documentation.
