Airworthiness Directive · Amendment 39-18287 · Fire protection
Dassault Aviation Airplanes
This AD applies to Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes, certificated in any category, all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by reports of defective fire extinguisher tubes. It was determined the defects were caused by corrosion. This AD requires repetitive general visual inspections of the fire extinguisher tubes for cracking and corrosion, and replacement of any cracked tube with a serviceable tube, if necessary. We are issuing this AD to detect and correct cracking and corrosion in the fire extinguisher tubes, which could impact the capability to extinguish an engine fire, and possibly result in damage to the airplane and injury to the passengers.
For airplanes identified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD: Within 13 months or 450 flight hours, whichever occurs first after the effective date of this AD, do a general visual inspection of the fire extinguisher tubes for cracking and corrosion, in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Dassault Aviation's EASA Design Organization Approval (DOA). Repeat the inspection thereafter at intervals not to exceed 13 months.
(1) Model FAN JET FALCON airplanes and Model FAN JET FALCON SERIES C, D, E, F, and G airplanes, equipped with any fire extinguisher tubes having part numbers MY20791-101, MY20791-101-1, MY20791-102, MY20791-102-1, MY20791-117, and MY20791-112.
(2) Model MYSTERE-FALCON 200 airplanes equipped with any fire extinguisher tubes having part numbers M20H791000210B1 and M20H791000240B1.
(3) Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes equipped with any fire extinguisher tubes having part numbers M20R791101, M20R791101A1, and M20R791102.
If, during any inspection required by paragraph (g) of this AD, any cracking or corrosion is found, before further flight, replace the tube with a serviceable tube having a part number specified in Table 1 to paragraph (h) of this AD, as applicable.
