FAA Demands Rust Checks on LAVIA PA-25 Airplane Wings
Published Date: 11/18/2025
Proposed Rule
Summary
The FAA wants all owners of LAVIA ARGENTINA S.A. PA-25 airplanes to check their wings for rust and cracks to keep flying safe. If any damage is found, repairs or replacements will be needed. Comments on this plan are open until January 2, 2026, so owners should get ready to act soon and possibly spend some money fixing their planes.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 6 costs, 0 mixed.
Mandatory wing-spar inspections
If you own or operate a LAVIA ARGENTINA S.A. Model PA-25, PA-25-235, or PA-25-260 airplane, you must inspect the front and rear wing spars for corrosion and cracks. Inspections must be done at intervals not to exceed 100 hours time-in-service (TIS) or 12 months, whichever occurs first, with initial compliance windows that include thresholds such as 5 years, 500 hours TIS, or within 10 hours TIS after the AD's effective date depending on the airplane's history.
Repair or replace before further flight
If any crack(s) or corrosion are found during required inspections, you must repair or replace the affected front or rear wing spar before further flight using a method approved by the FAA. The proposed AD explicitly requires repairs or replacements to address the unsafe condition to prevent a wing separating from the fuselage in flight.
Eddy‑current checks and 18‑month replacement rule
The AD requires eddy current inspections of the front wing spar flange in certain cases, with some airplanes required to undergo eddy current inspections every 50 hours TIS and others at up to 100 hours TIS or 12 months. Airplanes that must have eddy current inspections every 50 hours TIS must have the wing spar replaced within 18 months after starting those inspections.
FAA cost estimates and affected fleet size
The FAA estimates this proposed AD would affect 467 U.S.-registered airplanes. The FAA estimates an inspection for cracks at 16 work-hours (16 x $85/hr = $1,360 per inspection) and an inspection for corrosion at 8 work-hours (8 x $85/hr = $680 per inspection). The FAA also lists replacement work as involving 40 work-hours at $85 per hour.
Special flight permits not allowed
The proposed AD prohibits special flight permits for affected airplanes. That means you cannot fly the airplane under a special flight permit to move it to a maintenance facility if it is subject to this AD.
Must follow specific LAVIASA service bulletins
Compliance with this AD requires performing the actions described in LAVIASA aeroindustria Service Bulletin No. 25-57-09, REV 0 (Nov 27, 2023) and LAVIASA aviacion Service Bulletin No. 25-57-11, Rev 00 (Aug 23, 2024). These service bulletins describe inspection holes/doors, borescope and eddy current inspections, and related procedures you must use.

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.
