Airworthiness Directive · Amendment 39-18607 · Time limits/maintenance checks
Dassault Aviation Airplanes
Superseded. A later AD replaced this one: AD 2020-07-16. Comply with the one in force.
This AD applies to Dassault Aviation Model FALCON 7X airplanes, certificated in any category, all serial numbers.
We are superseding Airworthiness Directive (AD) 2011-10-01 for all Dassault Aviation Model FALCON 7X airplanes. AD 2011-10-01 required repetitive functional tests of the ram air turbine (RAT) heater, and repair if necessary. This new AD requires revision of the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. This AD was prompted by the need for new and more restrictive maintenance requirements and airworthiness limitations for airplane structures and systems. We are issuing this AD to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.
This paragraph restates the requirements of paragraph (g) of AD 2011-10-01, with new terminating action and specific delegation approval language. At the applicable times specified in paragraph (g)(1) or (g)(2) of this AD, do a functional test of the RAT heater using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Dassault Aviation's EASA Design Organization Approval (DOA). Repeat the functional test of the RAT heater thereafter at the applicable time specified in paragraph (g)(1) or (g)(2) of this AD until the revision required by paragraph (h) of this AD is done. If any functional test fails, before further flight, repair using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or EASA; or Dassault Aviation's EASA DOA.
(1) For Model FALCON 7X airplanes on which modification M0305 has not been done and on which Dassault Service Bulletin 7X-018, dated March 6, 2009, has not been done: Within 650 flight hours after the effective date of this AD, do a functional test of the RAT heater and repeat the functional test of the RAT heater thereafter at intervals not to exceed 650 flight hours.
(2) For Model FALCON 7X airplanes on which modification M0305 has been done or on which Dassault Service Bulletin 7X-018, dated March 6, 2009, has been done: Within 1,900 flight hours after June 9, 2011 (the effective date of AD 2011-10-01), or after modification M0305 or Dassault Service Bulletin 7X-018, dated March 6, 2009, has been done, whichever occurs later, do a functional test of the RAT heater. Repeat the functional test of the RAT heater thereafter at intervals not to exceed 1,900 flight hours.
Note 1 to paragraph (g) of this AD: Additional guidance for doing the functional test of the RAT heater required by paragraph (g) of this AD can be found in Task 24-50-25-720-801, Functional Test of the RAT Heater, dated January 16, 2009, of the Dassault FALCON 7X Aircraft Maintenance Manual (AMM).
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, by incorporating the information specified in Chapter 5-40-00, Airworthiness Limitations, DGT 107838, Revision 4, dated February 2, 2015, of the Dassault Falcon 7X Maintenance Manual (MM). The initial compliance times for the tasks specified in Chapter 5-40-00, Airworthiness Limitations, DGT 107838, Revision 4, dated February 2, 2015, of the Dassault Falcon 7X MM are at the applicable compliance times specified in Chapter 5-40-00, Airworthiness Limitations, DGT 107838, Revision 4, dated February 2, 2015, of the Dassault Falcon 7X MM, or within 30 days after the effective date of this AD, whichever occurs later.
(1) Accomplishment of the revision required by paragraph (h) of this AD terminates the requirements of paragraph (g) of this AD.
(2) Accomplishment of the revision required by paragraph (h) of this AD terminates the requirements of paragraph (q) of AD 2014-16-23.
After the maintenance or inspection program, as applicable, has been revised as required by paragraph (h) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k)(1) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
