FAA Orders Honda Jet Flap Replacements for Safety
Published Date: 12/23/2025
Proposed Rule
Summary
The FAA is updating safety rules for certain Honda HA-420 airplanes to fix a flap control part that could cause trouble by bumping into other parts. Owners will need to replace this part with a new, improved version to keep flying safe. Comments on this update are open until February 6, 2026, and the fix might cost some time and money but keeps everyone safer in the sky!
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Mandatory Pushrod Replacement Within 2 Years
If you own or operate an affected Honda HA-420 airplane, you must replace the flap control pushrod assemblies with redesigned assemblies within 2 years after the AD's effective date. The FAA estimates the replacement parts cost $5,168 plus 22 work-hours (22 x $85/hr = $1,870) for a total of $7,038 per airplane, affecting 107 U.S.-registered airplanes and a total estimated cost of $753,066.
Continued Repetitive Corrosion Maintenance
For Group 1 HA-420 airplanes, you must keep removing, cleaning, and applying corrosion inhibiting compound (CIC) to flap control pushrod assemblies within 90 days after November 19, 2021 or 18 months after first standard airworthiness certificate (whichever is later), and reapply CIC every 90 days or 300 hours time-in-service, whichever occurs first. The FAA estimates the recurring reapplication cost at $155 each time and lists costs on U.S. operators for these retained actions (e.g., $85,360 for 44 airplanes for the initial retained action, and $6,820 for repeated applications across 44 airplanes).
Prohibition on Installing Certain Pushrod Parts
As of the AD's effective date, you may not install any inboard or outboard flap control pushrod assembly part number identified in the Effectivity section of Honda Alert Service Bulletin SB-420-27-009 Revision B (dated August 5, 2025). This limits parts you can install during maintenance or repairs.
Manufacturer May Cover Some Costs Under Warranty
The FAA notes that, according to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, which could reduce the cost impact on affected operators.

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.
2026-16803, Notice of Availability, Notice of Public Comment Period and Request for Comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America
In accordance with the National Environmental Policy Act of 1969, as amended (NEPA) and FAA Order 1050.1G, FAA National Environmental Policy Act Implementing Procedures, the FAA is announcing the availability of and requesting comment on the Draft Environmental Assessment for Reditus Space ENOS Reentries in the Gulf of America (Draft EA).
2026-16795, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737 -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of nuisance stick shaker activation while accelerating to cruise speed at the top of a climb due to frozen angle of airflow (AOA) sensor vanes. This proposed AD would require installing new external case heaters (ECHs) on the left and right AOA sensors, performing repetitive functional tests and applicable corrective actions, and accomplishing applicable concurrent actions. The FAA is proposing this AD to address the unsafe condition on these products.
2026-16804, Establishment of Class E Airspace; Trading Bay Production Airport, Trading Bay, AK
This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Trading Bay Production Airport, Trading Bay, AK. This action would support the safety and management of instrument flight rules (IFR) operations at the airport.
