FAA Orders Checks on Airbus Helicopter Rotor Parts for Safety
Published Date: 2/18/2025
Rule
Summary
If you fly or fix Airbus EC225LP helicopters, listen up! The FAA updated safety rules to check and possibly replace certain main rotor parts to keep flights safe. These new rules start March 5, 2025, and add more parts to watch out for, so don’t wait to inspect or replace them—your helicopter’s safety depends on it!
Analyzed Economic Effects
7 provisions identified: 1 benefits, 6 costs, 0 mixed.
Mandatory repetitive inspections and replacements
If you operate an Airbus Helicopters Model EC225LP, you must perform repetitive inspections of certain main rotor (M/R) mast assemblies and mast swashplate assemblies for defective ceramic balls in the swashplate bearing, and, depending on findings, replace the affected M/R mast assembly or mast swashplate assembly with a serviceable part. The AD incorporates EASA AD 2024-0160 (dated August 16, 2024) and retains the inspection-and-replace requirements from AD 2021-04-18.
Potentially very large on-condition replacement costs
If inspections find discrepancies, corrective actions are estimated at 100 work-hours (labor $8,500) plus parts. Airbus informed the FAA parts costs may be as low as $1,120,000 per helicopter, and the FAA estimates average parts costs between $1,120,000 and $3,256,000 per helicopter for on-condition repairs/replacements.
Repairs permitted instead of mandatory removal from service
The FAA updated an exception so that certain parts previously required to be removed from service may instead be repaired and returned to service. The AD notes operators may repair those parts and return them to service rather than mandatorily discarding them.
Immediate compliance deadline and inspection timing
The AD is effective March 5, 2025, and the FAA notes the compliance time for the initial instance of the repetitive inspections is 50 hours time-in-service. The FAA found the 50-hour initial compliance interval is shorter than typical public comment periods, prompting immediate adoption.
No special flight permits allowed
The AD explicitly prohibits special flight permits for affected helicopters. Operators may not use special flight permits to fly affected helicopters for the purposes allowed under special flight permits.
Estimated inspection costs and U.S. fleet impact
The FAA estimates the AD affects 28 U.S.-registered EC225LP helicopters. Each inspection cycle is estimated at 4 work-hours at $85/hour (labor = $340) with a parts cost of $0, for $340 per inspection cycle and a total estimated cost to U.S. operators of $9,520 per inspection cycle across the fleet.
Inspection method clarified for swashplate check
Where EASA AD 2024-0160 refers to work steps described in a video, this AD requires a complete rotation of the swashplate in both directions at a rate of one revolution per minute as the inspection method.

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.

The FAA is updating the airspace rules around Jack Northrop Field/Hawthorne Municipal Airport in California to better manage both instrument and visual flights. These changes, effective June 12, 2025, will improve safety and match official records without costing anyone extra. Pilots flying in and out of this airport will notice clearer, safer airspace boundaries.

Starting February 12, 2025, fishermen in Management Area 3 can only catch and keep up to 2,000 pounds of Atlantic herring per trip or day. This limit helps prevent overfishing since the herring catch is almost at its yearly cap. The rule lasts until the end of 2025 and aims to keep the fishery healthy and avoid stricter limits next year.
