The FAA proposes to adopt a new airworthiness directive AD for certain Dassault Aviation Model FALCON 7X FALCON 900EX and FALCON 2000EX airplanes. This proposed AD was prompted by reported occurrences of swelling of the lithium-polymer internal and external batteries of certain electronic display units EDUs. This proposed AD would require modifying certain EDUs and would prohibit the installation of affected parts as specified in a European Union Aviation Safety Agency EASA AD which is proposed for incorporation by reference IBR. The FAA is proposing this AD to address the unsafe condition on these products.
