Summary
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX airplanes. This proposed AD was prompted by a determination that new or more restrictive maintenance requirements and/or airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and/or airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
