AD 2007-02-01 Airworthiness Directives; Dassault Model F2000EX Airplanes

Models named: Falcon 2000EX. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to Dassault Model Falcon 2000EX airplanes; s/n (serial number) 06, s/n 28 through 90, s/n 93, and s/n 95; certificated in any category. Reason (d) The MCAI states that troubleshooting of a “ENG 1 FIRE DETECT FAIL” CAS (crew alerting system) message that occurred on an in-service aircraft revealed that the detector threshold tolerances could not identify a single failure of one engine fire detector loop out of the two present on each engine. The fire detection system is therefore not correctly monitored, and its integrity is not guaranteed at all times. The goal of the MCAI is to verify the fire detection system integrity by mandating a one-time inspection and, in case of findings, to replace the faulty detector pending further modification of the monitoring system. The MCAI will be revised/superseded once the terminating corrective action for the monitoring function has been approved.

Unless already done, do the following actions. Within 35 days after the effective date of this AD, perform an engine fire detection integrity check as required by paragraphs (e)(1), (e)(2), and (e)(3) of this AD in accordance with Dassault Service Bulletin F2000EX-137, Revision 1, dated December 7, 2006. (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 the effective date of this AD in accordance with Dassault Service Bulletin F2000EX-137, dated November 23, 2006, are acceptable for compliance with the requirements of paragraph (e) of this AD. Other FAA AD Provisions (f) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, ATTN: Tom Rodriguez, 1601 Lind Avenue, SW., Renton, Washington 98057-3356, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056. Related Information (g) Refer to MCAI European Aviation Safety Agency (EASA) Emergency Airworthiness Directive 2006-0356-E, dated November 30, 2006; and Dassault Service Bulletin F2000EX-137, dated November 23, 2006; or Revision 1, dated December 7, 2006; for related information. Material Incorporated by Reference (h) You must use Dassault Service Bulletin F2000EX-137, Revision 1, dated December 7, 2006, to do the actions required by this AD, unless the AD specifies otherwise.
