Summary
We propose to adopt a new airworthiness directive (AD) for certain DASSAULT AVIATION Model FALCON 900EX airplanes. This proposed AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce a corrosion prevention control program, among other changes, to the maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to include the maintenance tasks and airworthiness limitations specified in the Airworthiness Limitations section of the airplane maintenance manual. We are proposing this AD to prevent reduced structural integrity of the airplane, and prevent reduced controllability of the airplane.
