Airworthiness Directives; Dassault Aviation Airplanes
Published Date: 2/6/2026
Proposed Rule
Summary
If you own or work with certain Dassault Mystere-Falcon 20 airplanes, the FAA wants you to update your maintenance plans with new, stricter safety rules. These changes build on last year’s rules to keep the planes safer and avoid problems. You’ve got until March 23, 2026, to share your thoughts, and while these updates might cost some time and money, they’re all about keeping flights safe and sound.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Operators Must Update Maintenance Programs
If you operate Dassault MYSTERE-FALCON 20-C5, -D5, -E5, or -F5 airplanes, the FAA would require you to revise your maintenance or inspection program to add new or more restrictive airworthiness limitations as specified in EASA AD 2025-0126 and retain requirements from AD 2023-20-05. The rule requires making those revisions within 90 days after the effective date of this AD and you must follow the specified actions and compliance times.
Estimated Compliance Cost Per Operator
The FAA estimates this proposed AD affects 61 U.S.-registered airplanes. The agency estimates the retained actions from AD 2023-20-05 will cost each operator $7,650 (90 work-hours × $85/hour), and the newly proposed actions will also cost each operator $7,650 (90 work-hours × $85/hour).
Rule Targets Fatigue and Corrosion Risk
The FAA says the AD is intended to address fatigue cracking, damage, and corrosion in principal structural elements of the affected Mystere-Falcon 20 airplanes because those conditions could reduce the airplane's structural integrity. The proposed rule would therefore require actions aimed at preventing those unsafe conditions.
