Falcon 7X: Mandatory MAIC Software and AFM Updates
If you own or operate a Dassault Model FALCON 7X airplane identified in EASA AD 2025-0092, you must modify the maintenance and avionics interface computer (MAIC) software (Dassault modification M2138), and revise the airplane flight manual (AFM) to add procedures for slat failures. The AD requires accomplishing applicable prior modifications (Dassault modification M1968 or M1655, as applicable) before M2138 and directs compliance within the times specified in EASA AD 2025-0092; this AD is effective July 9, 2026.
FAA Cost Estimate: 25 U.S. Falcons Affected
The FAA estimates this AD affects 25 U.S.-registered airplanes. The FAA estimates up to 24 work-hours at $85/hour (up to $2,860) in labor and up to $4,900 in parts per airplane, and estimates the total cost on U.S. operators up to $122,500. The FAA also lists special tooling rental costs of $929, $981, and $950 per day for modifications M2138, M1968, and M1655 respectively, and notes the manufacturer may cover some or all costs under warranty.
Finishes Prior AD Requirements for Some Falcons
