FAA Demands Bolt Swaps to Keep Helicopters Aloft
Published Date: 6/2/2025
Proposed Rule
Summary
If you fly Airbus Helicopters AS 332L2 or EC 225LP models, listen up! The FAA wants you to swap out some bolts on the main gearbox suspension bar because the old ones might be too long or bent. You'll also need to check those bolts and tell Airbus what you find—keeping your chopper safe and sound without breaking the bank.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Required replacement of MGB suspension bolts
If you operate an Airbus Helicopters Model AS 332L2 or EC 225LP, the FAA proposes you must replace certain attachment bolts on the main gearbox (MGB) suspension bar fittings. The replacement is required because reports found overlengthened and deformed attachment bolts on the suspension bar link.
Inspection of removed attachment bolts
The proposed rule requires inspecting the removed attachment bolts from the MGB suspension bar link. Inspecting the bolts is meant to identify overlengthened or deformed bolts that could cause an unsafe condition.
Mandatory reporting of inspection results to Airbus
The FAA proposes that operators must report the results of the bolt inspections to Airbus Helicopters. Reporting the inspection results is required as part of the directive to document findings for the unsafe condition investigation and corrective 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.
2026-16803, 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.
