Dassault Falcons Face Avionics Overhaul by FAA Deadline
Published Date: 11/28/2025
Rule
Summary
If you own certain Dassault Falcon 7X airplanes, the FAA has updated safety rules that require fixing a weak spot in the plane’s avionics system and updating flight manuals and equipment lists. These changes build on earlier rules and remove some planes from the list. The new rules kick in January 2, 2026, and might cost some time and money but make flying safer and smarter.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Optional EASy IV upgrade (expensive alternative)
The AD and incorporated EASA material describe an optional method of compliance by modifying the avionics architecture to the EASy IV standard; accomplishing that optional upgrade is available but can cost up to $808,064 per airplane (up to 302 work-hours at $85/hr = $25,670 labor plus up to $782,394 parts).
Required avionics system modification
The AD requires modifying the Falcon 7X avionics system to fix a weak point in the avionics architecture and making related AFM and MEL revisions. The FAA estimates the new required modification labor cost at 10 work-hours (10 x $85 = $850) per airplane and estimates this AD affects 160 U.S.-registered airplanes.
Keep AFM and MEL revisions
If you operate an affected Dassault Falcon 7X, this AD continues to require revising the airplane flight manual (AFM) and the operator's FAA-approved minimum equipment list (MEL). The AD requires the AFM revision within 2 months after September 1, 2022, and the FAA estimates the retained AFM and MEL revision action costs $170 per airplane.
Some Falcons removed from AD coverage
This AD removes certain Falcon 7X airplanes from applicability — specifically airplanes on which Dassault modification M2055, M2059, M2096, or M2097 were embodied in production — so those airplanes are not subject to the AD's required actions.

2026-13440 — Enabling Supersonic Overland Flight
The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
2026-13126 — Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility; Extension of Comment Period
The FAA is giving more time—until August 5, 2026—for people to share their thoughts on new rules that would limit drone flights near important fixed sites like power plants or airports. This affects drone operators and facility owners who want to keep the skies safe and secure. No new costs yet, just extra time to weigh in and help shape the rules.
2026-08943 — Designation-Restrict the Operation of Unmanned Aircraft in Close Proximity to a Fixed Site Facility
The FAA is proposing new rules to keep drones away from certain important fixed sites like power plants or airports to keep everyone safe and secure. If you own or operate one of these sites, you can request a drone flight restriction zone to protect your property and people nearby. Comments are open until July 6, 2026, and these changes could affect drone pilots and site operators, but no big costs are expected.
2026-13472 — Establishment of Class E Airspace; Jewett, TX
Starting October 29, 2026, the FAA is creating new Class E airspace around Hub Field in Jewett, Texas, to help pilots use new instrument flight procedures safely. This change mainly affects pilots flying in and out of Jewett, making flying safer and smoother without extra costs or delays. So, if you’re a pilot or involved in local aviation, get ready for clearer skies and better guidance!
2026-13475 — Airworthiness Directives; The Boeing Company Airplanes
The FAA is making sure certain Boeing 787 airplanes stay safe by fixing door handles that have been coming loose during pre-flight checks. Starting August 6, 2026, airlines must install new parts and do inspections to keep these doors secure. This update helps prevent safety issues without causing big delays or costs.
2026-13477 — Agency Information Collection Activities: Requests for Comments; Clearance of a Renewed Approval of Information Collection: Maintenance, Preventive Maintenance, Rebuilding, and Alteration
The FAA is asking for your thoughts on renewing a form that tracks important airplane maintenance and repairs to keep flying safe. This affects aircraft owners and mechanics who fill out Form 337 after major fixes or changes, which takes about an hour each. Comments are open until August 3, 2026, and this process helps ensure safety without adding extra costs.

If you fly or work with Airbus A350-941 and -1041 planes, listen up! The FAA found some weird noises coming from the nose landing gear and now requires regular checks and fixes to keep things safe. Starting January 2, 2026, these inspections must happen often, and some parts can’t be installed anymore—so airlines should plan for extra maintenance and costs.

The USDA is making crop insurance easier and fairer for farmers starting November 30, 2025. They’re updating rules to clear up confusing parts, remove some limits on selling crops directly, and change how certain coverages work—like stopping buy-up coverage for prevented planting. These updates affect farmers with contracts renewing in 2026 or later and aim to protect their crops better while simplifying the process.
