Summary
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON, Model MYSTERE-FALCON 20-C5, 20- D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of defective fire extinguisher tubes. This proposed AD would require replacement of the affected fire extinguisher tubes with improved fire extinguisher tubes. We are proposing this AD to address the unsafe condition on these products.
