Airworthiness Directive · Amendment 39-15562 · Navigation
Dassault Model Falcon 2000EX Airplanes and Model Falcon 900EX Airplanes
This AD applies to Dassault Model Falcon 2000EX airplanes, serial number (S/N) 6, and S/N 28 and subsequent; and Model Falcon 900EX airplanes, S/N 97, and S/N 120 and subsequent; certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) For Model Falcon 2000EX airplanes without Dassault Modification M2758 and Model Falcon 900EX airplanes without Dassault Modification M5143 in the applicability range: Within 3 months after the effective date of this AD, do the IRS2 wiring modification and test the GP (general purpose) bus IRS entry. Do all actions in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000EX-89, dated March 17, 2006; or Dassault Service Bulletin F900EX-274, dated March 17, 2006; as applicable. Repeat the test at intervals not to exceed 5,000 flight hours. If the GP bus IRS entry fails any test, before further flight, do all applicable corrective actions in accordance with the procedures in Section 34-209, dated March 2007, of the Dassault Falcon 900EX EASy/900DX Maintenance Manual; or Section 34-209, dated May 2007, of the Dassault Falcon 2000EX EASy Maintenance Manual; as applicable.
(2) For Model Falcon 2000EX airplanes with Dassault Modification M2758 and Model Falcon 900EX airplanes with Dassault Modification M5143 in the applicability range: Within 5,000 flight hours after the date of issuance of the original French standard airworthiness certificate or the date of issuance of the original French export certificate of airworthiness, or within 3 months after the effective date of this AD, whichever occurs later, do a test of the GP bus IRS entry in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000EX-89, dated March 17, 2006; or Dassault Service Bulletin F900EX-274, dated March 17, 2006; as applicable. Repeat the test at intervals not to exceed 5,000 flight hours. If the GP bus IRS entry fails any test, before further flight, do the corrective actions in accordance with the procedures in Section 34-209, dated March 2007, of the Dassault Falcon 900EX EASy/900DX Maintenance Manual; or Section 34-209, dated May 2007, of the Dassault Falcon 2000EX EASy Maintenance Manual; as applicable.
Note: This AD differs from the MCAI and/ or service information as follows:
(1) Where the MCAI specifies to do a test of the GP bus IRS entry in accordance with Chapter 5.40 of the applicable Dassault Maintenance Manual and does not specify a corrective action, we require those corrective actions to be done in accordance with Section 34-209, dated March 2007, of the Dassault Falcon 900EX EASy/900DX Maintenance Manual; or Section 34-209, dated May 2007, of the Dassault Falcon 2000EX EASy Maintenance Manual; as applicable.
(2) The MCAI specified to revise the applicable Dassault MMEL by incorporating Dassault Temporary Change 4, dated June 15, 2006, to the Dassault Falcon 2000EX EASy MMEL (for Model F2000EX EASy airplanes); and Dassault Temporary Change 3, dated June 15, 2006, to the Dassault Falcon 900EX EASy MMEL (for Model F900EX EASy airplanes); as applicable. However, the FAA-approved MMEL (which is required to be used by operators) has been revised to include the information specified in the Dassault temporary changes. Therefore, we have not included a requirement for this revision in 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.
