## Abstract

We are adopting 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 AD was prompted by reports of the collapse of the main landing gear (MLG) on touchdown. This AD requires an electrical modification of the landing gear sequence logic. We are issuing this AD to address the unsafe condition on these products.
