We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by a report of an in-flight lightning strike to the WHELEN anti- collision light located on the top of the vertical fin tip that caused severe damage and resulted in the loss of some airplane functions. This AD requires modification of the anti-collision light bonding. We are issuing this AD to prevent loss of electrical power and essential airplane functions, and possible reduced control of the airplane.
Within 24 months after the effective date of this AD, modify the anti-collision light bonding, in accordance with the Accomplishment Instructions of the applicable service information specified in paragraphs (g)(1) through (g)(7) of this AD.
