Airbus A321s Get Crack-Proofing Mandate from FAA
Published Date: 2/27/2025
Proposed Rule
Summary
The FAA wants to update safety rules for certain Airbus A321 planes to keep them safe from cracks in the cabin floor beams. They’re changing inspection schedules to include flight hours and adding options for fixes. Airlines need to comment by April 14, 2025, and while this might cost some time and money, it’s all about keeping flights safe and sound.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 3 costs, 1 mixed.
Inspections now tied to flight hours
If you operate Airbus A321-111/-112/-131/-211/-212/-213/-231/-232 airplanes, the AD keeps the repetitive inspections for cracking at the cabin floor beam junction (frames 35.1 and 35.2, left and right) and revises the inspection compliance times so they are also based on flight hours by requiring compliance with EASA AD 2024-0128. The inspections and required repairs from AD 2017-14-14 remain in force but with the updated timing rules.
Optional modification can extend inspections
The rule adds optional modification instructions (for pre-mod 155607 and post-mod 155607 configurations) that operators may use to extend an inspection interval by following the optional modification procedures in EASA AD 2024-0128. Performing the optional modification is not required but available as an alternative to more frequent inspections.
Estimated U.S. fleet compliance cost
The FAA estimates this AD would affect 494 U.S.-registered airplanes. The retained (required) inspection actions are estimated up to 8 work-hours at $85/hour (up to $680) per airplane, for an aggregate estimated cost to U.S. operators of up to $335,920.
Potential repair costs if cracks found
If inspections find cracking that requires on-condition repairs, the FAA estimates those repairs could require up to 50 work-hours ($4,250 labor) plus parts (estimated $1,600), for a cost per product of up to $5,850.
No requirement to submit inspection reports
Although EASA AD 2024-0128 specifies submitting certain inspection information to the manufacturer, this FAA AD explicitly does not include that reporting requirement, so operators are not required by this AD to send the inspection report sheet to the manufacturer.

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.
2025-04846, Extension of the Prohibition Against Certain Flights in the Territory and Airspace of Libya
The FAA is extending the ban on certain flights over Libya for three more years, until March 20, 2028. This affects U.S. airlines, commercial operators, and pilots with FAA certificates flying in Libyan airspace, due to ongoing safety risks. The rule also reminds everyone how to apply for special approvals or exemptions if needed.
2025-03853, Enforcement Policy Regarding “Drug and Alcohol Testing of Certificated Repair Station Employees Located Outside of the United States; Correction”
The FAA is giving repair stations outside the U.S. a break by delaying enforcement of new drug and alcohol testing rules until March 20, 2025. This means affected repair stations don’t have to worry about penalties if they aren’t fully following the updated rules just yet. The delay helps everyone get ready without rushing or extra costs.
