Airworthiness Directive · Amendment 39-19812 · Fire protection
Dassault Aviation Airplanes
This AD applies to all Dassault Aviation Model MYSTERE FALCON 50, MYSTERE FALCON 900, and FALCON 900EX airplanes; and Model FALCON 2000 and FALCON 2000EX airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model MYSTERE FALCON 50, MYSTERE FALCON 900, and FALCON 900EX airplanes; and Model FALCON 2000 and FALCON 2000EX airplanes. This AD was prompted by a report that the Dassault maintenance planning document (MPD) of the related Dassault aircraft maintenance manual (AMM) states that the "combined service/storage life" of the fire extinguisher percussion cartridges is longer than it should be, and could have a safety impact in case of fire. This AD requires replacing the fire extinguisher percussion cartridges with serviceable parts. The FAA is issuing this AD to address the unsafe condition on these products.
For the purpose of this AD, the definitions specified in paragraphs (g)(1) through (4) apply to this AD.
(1) An affected part is a fire extinguisher percussion cartridge having part number (P/N) 862700-00 or P/N 862710-00.
(2) Total life is time since the manufacturing date, which includes both the time installed on an airplane and time in storage.
(3) A serviceable part is an affected part that has not exceeded 10 years of total life, or a fire extinguisher percussion cartridge that is not an affected part.
(4) Group 1 airplanes are those that have an affected part installed. Group 2 airplanes are those that do not have an affected part installed.
For Group 1 airplanes, except as specified in paragraph (j) of this AD: Before a fire extinguisher percussion cartridge exceeds 10 years of total life, remove the affected part and replace it with a serviceable part in accordance with the procedures specified in paragraph (l)(2) of this AD.
Guidance for the replacement required by paragraph (h) of this AD can be found in the applicable Dassault AMM task specified in figure 1 to paragraph (i) of this AD.

For Group 1 and Group 2 airplanes: As of the effective date of this AD, no person may install, on any airplane, a fire extinguisher percussion cartridge, unless the part is a serviceable part as specified in this AD, and that, following installation, the affected part is replaced as required by paragraph (h) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
