## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2023-18-07, which applies to certain Dassault Aviation Model MYSTERE- FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2023-18-07 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-18-07, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require certain actions in AD 2023-18-07 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
