## Summary

We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES D, E, F, and G airplanes; and certain Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This proposed AD was prompted by reports of the collapse of the main landing gear on touchdown. This proposed AD would require an electrical modification of the landing gear sequence logic. We are proposing this AD to address the unsafe condition on these products.
