Summary
We propose to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX airplanes. This proposed AD was prompted by reports of rejected take-offs due to untimely inboard flap retraction. This proposed AD would require modification of the slat/flap control wiring and replacement of the slat/flap control box with an improved box. We are proposing this AD to address the unsafe condition on these products.
