Airworthiness Directive · Amendment 39-15711 · Fire protection
Dassault Model Falcon 2000EX Airplanes
This AD applies to Dassault Model Falcon 2000EX airplanes, certificated in any category, serial number (S/N) 06 and from S/N 28 to 107 inclusive, without modification M2958 implemented.
We are superseding an existing 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. Within 35 days after February 2, 2007 (the effective date of AD 2007-02-01), perform an engine fire detection integrity check as required by paragraphs (f)(1), (f)(2), and (f)(3) of this AD in accordance with Dassault Service Bulletin F2000EX-137, Revision 1, dated December 7, 2006. Doing the replacement required by paragraph (g) of this AD terminates the requirements of this paragraph.
(1) First, in the baggage compartment, on each mobile connector of the monitoring units (L320WG) and (R320WG), the equivalent resistance of the two engine detectors at the LH (left-hand) and the RH (right-hand) sides must be verified. According to findings, the corresponding system is either considered correct or incorrect.
(2) As a second step, if either one or both the LH and the RH system is (are) found to be incorrect, it is required to check the actual resistance of both detectors of the incorrect system(s) on the affected engine(s).
(3) Any faulty detector must be replaced prior to further flight.
(4) Actions done before February 2, 2007, in accordance with Dassault Service Bulletin F2000EX-137, dated November 23, 2006, are acceptable for compliance with the requirements of paragraph (f) of this AD.
Unless already done, within the next 12 months after the effective date of this AD, remove the two fire monitoring units having part number (P/N) 6342-01 and replace them with new ones having P/N 6342-02 in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F2000EX-138, dated March 5, 2007. Doing the replacement terminates the requirements of paragraph (f) of this AD.
