Airworthiness Directive · Amendment 39-17642 · Fire protection
Dassault Aviation Airplanes
This AD applies to the Dassault Aviation airplanes identified in paragraphs (c)(1) through (c)(3) of this AD, certificated in any category, all serial numbers.
(1) Model Fan Jet Falcon airplanes.
(2) Model Mystere-Falcon 200 airplanes.
(3) Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes.
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model Fan Jet Falcon; 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 bottle cartridges. This AD requires checking manufacturing references of pyrotechnical cartridges for batch number and date, repetitive checking of cartridges for electrical continuity, and replacing defective pyrotechnical cartridges if necessary. We are issuing this AD to detect and correct defective fire bottle cartridges, which could impact the capability to extinguish a fire in an engine, auxiliary power unit, or rear compartment, which could result in damage to the airplane and injury to the occupants.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For airplanes equipped with fire extinguisher bottle cartridges having a part number (P/N), batch number, and manufacturing date as listed in paragraph (g)(1), (g)(2), or (g)(3) of this AD: Within 30 days or 100 flight hours, whichever occurs first after the effective date of this AD, check the manufacturing references of pyrotechnical cartridges for batch number and date, and check the cartridges for electrical continuity and resistance, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F20-783, Revision 1 (also referred to as 783-R1), dated June 11, 2012 (for Model Fan Jet Falcon and Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes); or Dassault Mandatory Service Bulletin F200-128, Revision 1 (also referred to as 128-R1), dated June 11, 2012 (for Model Mystere-Falcon 200 airplanes).
(1) P/N 12-12-11707S1-4, with batch up to 44 inclusive, manufactured before May 2012.
(2) P/N 12-12-11707S2-4, with batch up to 33 inclusive, manufactured before May 2012.
(3) P/N 12-12-11707S3-4, with batch up to 44 inclusive, manufactured before May 2012.
If, during any check as required by paragraphs (g) and (i) of this AD, a discrepancy [excessive resistance] is identified, before next flight, replace the discrepant fire extinguisher bottle cartridge(s) with a serviceable part, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F20-783, Revision 1 (also referred to as 783-R1), dated June 11, 2012 (for Model Fan Jet Falcon and Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes); or Dassault Mandatory Service Bulletin F200-128, Revision 1 (also referred to as 128-R1), dated June 11, 2012 (for Model Mystere-Falcon 200 airplanes). Replacement of discrepant fire extinguisher bottle cartridges with a serviceable part terminates the repetitive actions required by paragraph (i) of this AD for that cartridge.
At the applicable time specified in paragraph (i)(1) or (i)(2) of this AD, repeat the checks required by paragraph (g) of this AD.
(1) For airplanes equipped with fire extinguisher bottle cartridges having P/N 12-12-11707S3-4, having a batch number, and manufacturing date, as listed in paragraph (g)(3) of this AD, at intervals not to exceed 65 days.
(2) For airplanes equipped with fire extinguisher bottle cartridges having P/N 12-12-11707S1-4 or P/N 12-12-11707S2-4, having a batch number, and manufacturing date, as listed in paragraph (g)(1) or (g)(2) of this AD, at intervals not to exceed 12 months.
Except as required by paragraph (h) of this AD: Within 30 months after installation of an affected fire extinguisher bottle cartridge on an airplane, or within 36 months since cartridge manufacturing date, whichever occurs first after the effective date of this AD, replace each affected fire extinguisher bottle cartridge listed in paragraphs (g)(1), (g)(2), and (g)(3) of this AD, with a serviceable part, in accordance with the Accomplishment Instructions of Dassault Mandatory Service Bulletin F20-783, Revision 1 (also referred to as 783-R1), dated June 11, 2012 (for Model Fan Jet Falcon and Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes); or Dassault Mandatory Service Bulletin F200-128, Revision 1 (also referred to as 128-R1), dated June 11, 2012 (for Model Mystere-Falcon 200 airplanes). Replacing the affected fire extinguisher bottle cartridge with a serviceable part as required by paragraph (h) or (j) of this AD, terminates the repetitive actions required by paragraph (i) of this AD for that cartridge.
