ATR Planes Get Stricter Safety Scrutiny from FAA
Published Date: 1/5/2026
Rule
Summary
The FAA is updating safety rules for certain ATR42-500 airplanes to keep them flying safely. Owners must update their maintenance plans with new, stricter checks starting February 9, 2026. This helps prevent problems but might mean some extra work and costs for operators.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Must update maintenance program fast
If you operate an ATR42-500 with an original airworthiness certificate issued on or before July 30, 2024, you must revise your existing maintenance or inspection program to add new, stricter airworthiness limitations. The AD is effective February 9, 2026, and you must make this revision within 90 days after that effective date.
FAA estimates $7,650 compliance cost
The FAA estimates this AD affects 11 U.S.-registered airplanes and that revising the maintenance or inspection program takes about 90 work-hours per operator at $85 per hour, for an average total cost per operator of $7,650 (90 hours × $85/hour).
Some prior AD tasks will be ended
If you accomplish the actions required by this AD, it will terminate the corresponding requirements of paragraph (j) of AD 2024-19-02 for the tasks identified in the material referenced in EASA AD 2025-0005.

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.

The FAA is making a new rule for certain Airbus A319, A320, and A321 airplanes to fix a safety problem where the autopilot caused a brief drop in altitude. Airlines must replace or update a key computer part called the ELAC to keep flights safe. This rule starts January 6, 2026, and could mean some costs and quick action for plane owners.

The EPA is giving states more time to submit their plans to improve air quality and protect clear skies in special natural areas. Instead of the original July 31, 2028 deadline, states now have until July 31, 2031 to get their plans in. This extra time helps states better prepare without changing any funding or costs.
