EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2011-0246 

Date: 22 December 2011 

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 EC 1702/2003, Part 21A.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): 

Mystère-Falcon 50 aeroplanes 

TCDS Number: EASA.A.062 

Foreign AD: Not applicable 

Supersedure: This AD supersedes DGAC France AD F-2004-162 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 (including all commercial variants), all serial 

numbers. 

Reason: The airworthiness limitations and maintenance requirements for the MystèreFalcon 50 (MF50) type design are included in Dassault Aviation MystèreFalcon 50 Aircraft Maintenance Manual (AMM) chapter 5-40 and 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 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 restrictive maintenance 

requirements and/or airworthiness limitations. 

Dassault Aviation AMM chapter 5-40 revision 21 contains 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 introduced 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 2008-0072. MF50 AMM 

chapter 5-40 at revision 21 introduces extended inspection 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 comply with AMM chapter 

5-40 at revision 21 might constitute an unsafe condition. 

For the reasons described above, this AD, which supersedes DGAC France 

AD F-2004-162, requires the implementation of the maintenance tasks and 

airworthiness limitations, as specified in Dassault Aviation MF50 AMM chapter 

5-40 at revision 21. 

Effective Date: 05 January 2012 

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 MF50 AMM chapter 5-40 at Revision 21: 

 (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 Dassault Aviation MF50 

AMM Chapter 5-40) during any inspection as required by paragraph (1) of 

this AD, within the applicable compliance time specified in Dassault 

Aviation MF50 AMM Chapter 5-40, accomplish the applicable maintenance 

procedures for corrective actions in accordance with the approved 

maintenance documentation. If no compliance time is identified in Dassault 

Aviation MF50 AMM Chapter 5-40, accomplish the applicable corrective 

actions before next flight. If a detected discrepancy 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 previously, the approved 

Aircraft Maintenance Programme 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 

specified in Dassault Aviation AMM chapter 5-40 at Revision 21, 

 and 

(3.2) Complying with the approved Aircraft Maintenance Programme 

described in paragraph (3.1) of this AD. 

(4) Compliance with the requirements of paragraphs (1) and (2) of this AD, or 

as specified in paragraph (3) of this AD, also constitutes compliance with 

the requirements of the following ADs: 

 EASA AD 2008-0072, EASA AD 2008-0221 and EASA AD 2010-0080.
