### Type Approval Holder’s Name:
DASSAULT AVIATION Type/Model designation(s): Mystère-Falcon 50 aeroplanes

TCDS Number: EASA.A.062

Foreign AD: Not applicable
Supersedure: This AD supersedes DGAC France AD F-20 04-162 dated 13 October 2004 (EASA approval number 2004-10117).



### ATA 05 Time Limits and Maintenance Checks – Airworthiness Limitations – Amendment / Implementation

Manufacturer(s): DASSAULT AVIATION

Applicability: Mystère-Falcon 50 aeroplanes (includ ing all commercial variants), all serial numbers.

Reason: The airworthiness limitations and maintenan ce requirements for the MystèreFalcon 50 (MF50) type design are included in Dassau lt Aviation MystèreFalcon 50 Aircraft Maintenance Manual (AMM) chapte r 5-40 and approved by the European Aviation Safety Agency (EASA). EASA is sued AD 2008-0221 to require accomplishment of the maintenance tasks and implementation of the airworthiness limitations, as specified in Dassault Aviation MF50 AMM chapter 5-40 at revision 17. Since that AD was issued, Dassault Aviation issued MF50 AMM chapter 5-40 at revision 21, which introduces new or more restri ctive maintenance requirements and/or airworthiness limitations. Dassault Aviation AMM chapter 5-40 revision 21 cont ains among other changes the following requirements: - Corrosion Prevention and Control Programme (CPCP) . Compliance with this programme was required by DGAC France AD F-2004-162 (EASA approval number 2004-10117). A new CPCP approach is now intr oduced in MF50 AMM chapter 5-40 at revision 21;EASA AD No : 2011-0246

EASA Form 110 Page 2/3 - Check of overpressure tightness on pressurization control regulating valves. Compliance with this check is required by EASA AD 2 008-0072. MF50 AMM chapter 5-40 at revision 21 introduces extended ins pection interval; - Non destructive check of the flap tracks 2 and 5. Compliance with this check is required by EASA AD 2010-0080.
The maintenance tasks and airworthiness limitations , as specified in the MF50 AMM chapter 5-40, have been identified as mandatory actions for continued airworthiness of the MF50 type design. Failure to c omply with AMM chapter 5-40 at revision 21 might constitute an unsafe cond ition. For the reasons described above, this AD, which sup ersedes DGAC France AD F-2004-162, requires the implementation of the m aintenance tasks and airworthiness limitations, as specified in Dassault Aviation MF50 AMM chapter 5-40 at revision 21.

Effective Date: 05 January 2012

(2) In case of finding discrepancies (as defined in Dassault Aviation MF50 AMM Chapter 5-40) during any inspection as required by paragraph (1) of this AD, within the applicable compliance time spec ified in Dassault Aviation MF50 AMM Chapter 5-40, accomplish the appl icable maintenance procedures for corrective actions in accordance wit h the approved maintenance documentation. If no compliance time is identified in Dassault Aviation MF50 AMM Chapter 5-40, accomplish the appl icable corrective actions before next flight. If a detected discrepan cy is not identified in Dassault Aviation AMM chapter 5-40 at Revision 21, 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, unless accomplished prev iously, the approved Aircraft Maintenance Programme on the basis of whic h the operator or the owner ensures the continuing airworthiness o f each operated aeroplane: Incorporate all airworthiness limitations and main tenance tasks specified in Dassault Aviation AMM chapter 5-40 at Revision 21,
