Airworthiness Directive · Amendment 39-15567 · Ice and rain protection
Dassault Model Mystere-Falcon 20-C5, 20-D5, and 20-E5 Airplanes
This AD applies to Dassault Model Mystere-Falcon 20-C5, 20-D5, and 20-E5 airplanes, certificated in any category, all serial numbers.
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:
Within 7 months after the effective date of this AD, unless already done, do the following actions.
(1) Inspect to determine whether any wing anti-ice flexible hose having part number (P/N) FAL1006 or P/N ARM224A is installed. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the wing anti-ice flexible hose can be conclusively determined from that review. If any wing anti-ice flexible hose does not have P/N FAL1006 or P/N ARM224A, no further action is required by this AD for that hose, except as required by paragraph (f)(3) of this AD.
(2) Remove any wing anti-ice flexible hose having P/N FAL1006 or P/N ARM224A, and install a new hose having ESPA (brand) P/N 60503104509; in accordance with the Accomplishment Instructions of Dassault Service Bulletin F20-775, dated July 9, 2007.
(3) As of the effective date of this AD, no person shall install any flexible hose having P/N FAL1006 or P/N ARM224A on any Model Mystere-Falcon 20-C5, 20-D5, or 20-E5 airplane specified in the applicability of this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: The MCAI does not require inspecting to determine the part numbers of the wing anti-ice flexible hoses. This AD requires such an inspection.
