EASA AIRWORTHINESS DIRECTIVE

AD No.: 2013-0051

Date: 04 March 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].

Design Approval Holder’s Name:

DASSAULT AVIATION

Type/Model designation(s):

Falcon 900EX aeroplanes

TCDS Number: EASA.A.062

Foreign AD: Not applicable

Supersedure: None

ATA 05 Time Limits and Maintenance Checks – Airworthiness 

Limitations – Amendment / Implementation

Manufacturer(s): DASSAULT AVIATION

Applicability: Falcon 900EX aeroplanes, serial number (s/n) 1 to 96 inclusive and s/n 98 to 

119 inclusive.

Reason: The airworthiness limitations and maintenance requirements for the Falcon 

900EX type design are included in Dassault Aviation 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 F900EX AMM chapter 5-40 referenced DGT 113874 at 

revision 8.

Since that AD was issued, Dassault Aviation issued revision 12 of F900EX 

AMM chapter 5-40 which contains new or more restrictive maintenance 

requirements and/or airworthiness limitations and introduces, among others,

the following changes:

- Tasks renumbering,

- Introduction of a Corrosion Prevention Control Program (CPCP),

- Upgrade of screwjack of flap actuators from the older to the latest -3 version;

- Revised Time Between Overhaul for screwjack of flap actuators -3 version;

- Revised interval for checking the screw / nut play on screwjack of flap 

actuators -3 version;

- Removal of service life limit for screwjack of flap actuators;

- Test of flap asymmetry protection system. Compliance with this test is 

required by DGAC France AD 1999-082-024(B)R2, but F900EX AMM 

chapter 5-40 at revision 12 introduces an extended inspection interval;

- Inspection procedures of fuselage and wings;

- Check of overpressure tightness on pressurization control regulating valves.

Compliance with this check is required by EASA AD 2008-0072, but F900EX

AMM chapter 5-40 at revision 12 introduces an extended inspection interval;

- Check of overpressure relief valve vacuum supply lines.

The maintenance tasks and airworthiness limitations, as specified in the 

F900EX AMM chapter 5-40, have been identified as mandatory actions for 

continued airworthiness of the F900EX type design. Failure to comply with 

AMM chapter 5-40 at revision 12 may result in an unsafe condition.

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

maintenance tasks and airworthiness limitations, as specified in the Dassault 

Aviation F900EX AMM chapter 5-40 DGT 113874 at revision 12.

Effective Date: 18 March 2013

Required Action(s) 

and Compliance 

Time(s):

Required as indicated, unless previously accomplished:

(1) After the effective date of this AD, accomplish the following actions, as 

specified in Dassault Aviation F900EX AMM chapter 5-40 DGT 

113874 at revision 12:

(1.1) Replace each component before or upon reaching the applicable 

life limit, and

(1.2) Within the thresholds and intervals, accomplish all applicable

maintenance tasks.

(2) In case of finding discrepancies (as defined in the F900EX AMM 

Chapter 5-40 at Revision 12) during any inspection as required by

specified in F900EX AMM Chapter 5-40 at Revision 12, accomplish 

the applicable maintenance procedures for corrective actions in 

accordance with approved maintenance documentation.

If no compliance time is identified in the F900EX AMM Chapter 5-40

at Revision 12, accomplish the applicable corrective actions before 

next flight.

If a detected discrepancy is not identified in Dassault Aviation AMM 

chapter 5-40 at Revision 12, before next flight, contact Dassault 

Aviation for approved instructions and accomplish those instructions 

accordingly.

(3) Compliance with the requirements of paragraphs (1) and (2) of this 

AD can be demonstrated by:

(3.1) Revising as follows the approved Aircraft Maintenance 

Programme (AMP) on the basis of which the operator or the 

owner ensures the continuing airworthiness of each operated 

aeroplane:

Incorporate all airworthiness limitations and maintenance tasks, 

applicable thresholds and intervals specified in Dassault
