### ATA 2 6 Fire P rotection

– Extinguishing System

– Defective Charge I ndicators

– Inspection / Replacement

Manufacturer(s): Dassault Aviation, Avio ns Marcel Dassault

- Breguet Aviation
Applicability: Fan Jet Falcon aeroplanes, all Models, Mystère

- Falcon 20

- ( )5 aeroplanes, all Models, Mystère

- Falcon 200 and Mystère

- Falcon 20 GF aeroplanes, all manufacturer serial numbers.

Reasons : A manufacturing d efect of the charge indicator of fire extinguisher bottles has been reported on Dassault Aviation Fan Jet Falcon and Mystère

- Falcon 20 series aeroplanes

. The results of the investigations concluded that this defect may lead to corrosion of the charge indicator , causing improper indicat i o n of loss of pressure in side the bottle. In addition, the Part Numbers (P/N) of the fire extinguishers and batch numbers of the affected charge indicators have been identified

. This condition, if not detected and corrected, c oul d cons t itute a dormant failure that might impact the capability to extinguish a fire , either in an engine or the Auxiliary Power Unit ( APU ) or the rear compartment , possibly resulting in damage to the aeroplane and injury to the occupants

. For the reasons described above , this AD requires repetitive weighing of the affected fire extinguishers bottles and, ultimately replacement of the affected bottles with serviceable bottles

. In addition, this AD prohibits installation of an affected fire extinguisher bott le.
