Summary
We propose to adopt 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 proposed AD was prompted by reports of defective fire extinguisher bottle cartridges. This proposed AD would require 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 proposing this AD to detect and correct defective fire bottle cartridges, which could affect 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.
