Cracks in the Tail? FAA Orders Checks on Piaggio Airplane Stabilizers
Published Date: 1/21/2026
Proposed Rule
Summary
The FAA wants owners of Baykar Piaggio P-180 airplanes to check their vertical stabilizers for cracks and corrosion. They’re proposing regular inspections and one special test to keep these planes safe, with fixes if problems pop up. Comments on this plan are open until March 9, 2026, so owners should get ready to act soon and keep their planes flying strong.
Analyzed Economic Effects
5 provisions identified: 2 benefits, 3 costs, 0 mixed.
Estimated inspection and repair costs
The FAA estimates a one-time NDT inspection costs up to 27 work-hours at $85/hour = $2,295 per airplane (total U.S. cost up to $245,565 for 107 airplanes). Repetitive inspections are estimated up to 40 work-hours at $85/hour = $3,400 per inspection (total U.S. cost per inspection up to $363,800). On-condition repairs are estimated up to $24,800 (up to 280 work-hours at $85/hour plus up to $1,000 parts) and replacements up to $23,600 (up to 160 work-hours at $85/hour plus up to $10,000 parts).
Which P-180s the AD covers
This proposed rule applies only to Baykar Piaggio Model P-180 airplanes with manufacturer serial numbers 1002, 1004 through 3016, and 3018. The FAA estimates 107 of these airplanes are on the U.S. registry. If your airplane is one of these serial numbers, the rule would apply to you.
Required inspections and timing
You must do repetitive visual and non-destructive testing (NDT) inspections of the P-180 vertical stabilizer at intervals not to exceed 660 hours time-in-service (TIS) or 26 months, whichever comes first. Initial compliance is within 220 hours TIS or 13 months for serials 1002 and 1004–3016, and within 660 hours TIS or 26 months for serial 3018, plus a one-time NDT inspection as specified in Piaggio Service Bulletin 80-0493, Rev. 0 (dated November 21, 2024).
How to get approved repairs and stop inspections
If inspections find corrosion or cracks, you must do corrective actions before further flight using approved repair instructions. To obtain approved repair instructions (an RDAS), the proposed AD requires contacting the Manager, International Validation Branch, FAA; EASA; or Piaggio's EASA Design Organization Approval (DOA). Completing an action identified as a "terminating action" in Piaggio SB 80-0493, Rev. 0 stops the repetitive inspections for that airplane.
No mandatory reporting to manufacturer
Although several steps in Piaggio SB 80-0493, Rev. 0, ask operators to report inspection results to the manufacturer, this proposed AD does not require submitting inspection findings to Piaggio. You are not required by the AD to send those reports.

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.
2026-18601, Airworthiness Directives; Dassault Aviation Airplanes
The FAA is superseding Airworthiness Directive (AD) 2023-23- 06, which applied to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2023-23-06 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-23- 06, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023-23-06 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2023-22- 12, which applied to all Dassault Aviation Model FALCON 2000 airplanes. AD 2023-22-12 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2023-22-12, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2023- 22-12 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
