Stricter Checks Required for ATR Regional Airplanes Soon
Published Date: 1/5/2026
Rule
Summary
The FAA is updating safety rules for all ATR42-200, -300, and -320 airplanes to keep them flying safely. Owners and maintenance crews must update their maintenance plans with new, stricter checks starting February 9, 2026. This change helps prevent problems but might mean a bit more work and cost to keep these planes in top shape.
Analyzed Economic Effects
5 provisions identified: 2 benefits, 3 costs, 0 mixed.
New maintenance checks for ATR42 fleet
If you operate ATR42-200, -300, or -320 airplanes, you must revise your maintenance or inspection program to add new, more restrictive airworthiness limitations to prevent fuel tank ignition. The AD is effective February 9, 2026, and you must make the program revision within 90 days after that effective date.
Estimated compliance cost per operator
The FAA estimates this AD affects 17 U.S.-registered ATR42 airplanes and that revising the maintenance or inspection program takes about 90 work-hours per operator. The agency estimates an average total cost per operator of $7,650 (90 work-hours x $85 per hour).
Compliance time shortened to 90 days
The FAA requires revising the approved maintenance program within 90 days after the AD's effective date of February 9, 2026, instead of the 12 months specified in the related EASA rule. This means operators must complete the program change by May 10, 2026 (90 days after February 9, 2026).
Limits on alternative design-control approvals
After you revise your maintenance or inspection program as required, no alternative Critical Design Configuration Control Limitations (CDCCLs) are allowed unless they are approved as specified in the referenced EASA material. This restricts using unapproved alternative design controls.
Completing AD may terminate older AD tasks
Completing the actions required by this AD will terminate the corresponding requirements of AD 2025-10-06 for the tasks identified in the EASA AD 2025-0044 material. That can remove duplication for those specific tasks.

2026-15585, Requirements for Interference-Tolerant Radio Altimeter Systems
In July 2025, President Trump signed the One Big Beautiful Bill Act. Section 40002 of that law re-institutes the Federal Communications Commission's general auction authority and specifically directs the Commission to complete a system of competitive bidding for not less than 100 megahertz in the 3.98-4.2 gigahertz band (Upper C- band). This final rule supports the Federal Communications Commission's July 2026 Report and Order that makes 160 megahertz of the Upper C-band available for terrestrial wireless flexible use via a system of competitive bidding. To ensure safe, efficient, and reliable aviation operations in the presence of wireless signals in the C-band, the Federal Aviation Administration is issuing new regulations that require all radio altimeters to meet specific minimum performance requirements. These new radio altimeters must withstand interference from wireless signals in neighboring spectrum bands and continue to provide accurate altitude readings to both pilots and integrated aircraft safety systems. These regulations require all aircraft equipped with radio altimeters operating under part 121 and those aircraft with radio altimeters operating under part 129 with 30 or more passenger seats or a payload capacity of more than 7,500 pounds to comply with the minimum performance requirements by December 30, 2030, which is prior to the date the Federal Communications Commission authorizes the use of the Upper C-band for new wireless services, as stated in its Report and Order. All other aircraft equipped with radio altimeters that are required to comply with part 91, including aircraft operating under parts 125, 133, 135, 136, 137, 194, and all other aircraft operating under part 129 that are not subject to the initial deadline, must comply with the same minimum performance requirements on or before October 31, 2034.
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.
2026-17551, Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2024-25- 06, which applied to all Airbus SAS Model A318 and A320 series airplanes; and Model A319-111, -112, -113, -114, -115, -131, -132, - 133, -151N, -153N, and -171N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -253N, -271N, -272N, - 251NX, -252NX, -253NX, -271NX, -272NX, and -253NY airplanes. AD 2024- 25-06 required repetitive inspections of the main landing gear (MLG) door actuators and, depending on findings, accomplishment of applicable corrective actions, and prohibited the installation of affected parts. Since the FAA issued AD 2024-05-06, the FAA determined that replacing the MLG door actuators is necessary to address the unsafe condition, and the applicability and definition of an affected part must be expanded. This AD continues to require the actions in AD 2024-25-06, requires replacing affected parts with serviceable parts, and expands the applicability and definition of an affected part. The FAA is issuing this AD to address the unsafe condition on these products.
2026-17552, Airworthiness Directives; Airbus SAS Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-211, -212, -214, -216, -231, -232, and - 233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by a fatigue test that identified cracks in the forward and aft upper corner of the bulk cargo door. This AD requires a rototest inspection for cracks and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

Next: 2025-24241, Airworthiness Directives; Airbus SAS Airplanes
The FAA is rolling out a new safety rule for all Airbus A330 and A340 planes because some front doors have been jamming during emergency slide deployment. Starting February 9, 2026, airlines must regularly inspect these doors and fix any problems found to keep everyone safe. This means some extra checks and possible repairs, but it’s all about making sure passengers and crew can exit quickly in an emergency.
