2008-22-15 Dassault Aviation: Amendment 39-15711. Docket No. FAA- 2008-0830; Directorate Identifier 2007-NM-285-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December 11, 2008.
Affected ADs
(b) This AD supersedes AD 2007-02-01, Amendment 39-14888.
Applicability
(c) 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.
Subject
(d) Air Transport Association (ATA) of America Code 26: Fire Protection.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
"Investigations after a CAS (crew alerting system) message "ENG 1 FIRE DETECT FAIL'' that occurred on an in-service aircraft revealed that the detector threshold tolerances could not permit to identify the failure of one single engine fire detector loop out of the two present on each engine. The fire detection system integrity is therefore not correctly monitored.
"Airworthiness Directive (AD) No 2006-0356-E [which corresponds to FAA AD 2007-02-01] was initially issued to mandate the verification of the fire detection system integrity by a one time inspection.
"The current AD mandates installation of two new fire monitoring units of an improved design, each one of them is capable of monitoring the integrity of both detectors on the associated engine.''
Restatement of Requirements of AD 2007-02-01
(f) 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, oneach 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.
New Requirements of This AD: Actions and Compliance
(g) 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.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information as follows: No differences.
Other FAA AD Provisions
(h) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Tom Rodriguez, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-1137; fax (425) 227-1149. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.
(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.
