FAA Mandates Rudder Replacements for Piper Aircraft by 2025
FAA Mandates Rudder Replacements For Thousands Of Piper Aircraft
The Federal Aviation Administration (FAA) has issued a final airworthiness directive (AD) requiring the replacement of rudders on specific Piper series aircraft. This directive, effective March 20, 2025, addresses safety concerns stemming from reports of rudder failures due to fatigue and corrosion in rudder posts made from 1025 carbon steel. The new requirements mandate the replacement of these components with more durable 4130N low-alloy steel rudders.
Two non-fatal accidents in Anchorage, Alaska, involving Piper aircraft with rudder post failures occurring in 2020 and 2022 prompted the FAA to issue the AD. During a comment period, the FAA received feedback from individuals and aviation groups on the AD with several raising concerns about cost and implementation challenges. The Aircraft Owners and Pilots Association (AOPA) argued for limiting the scope or rescinding the AD altogether. According to the association, approximately 31,000 vintage Piper aircraft will require new rudders or an approved alternative compliance method within the next two to ten years to maintain airworthiness.
Background Information
The FAA has a long history of issuing airworthiness directives (ADs) to ensure the safety of aircraft and their occupants. These directives are typically prompted by incidents, accidents, or other safety concerns that require mandatory actions to address potential safety hazards. In the case of the recent FAA mandate for rudder replacements on Piper aircraft, the background involves two non-fatal accidents that occurred in Anchorage, Alaska. The first accident happened on June 8, 2020, involving a Piper PA-12, and the second on July 23, 2021, involving a Piper PA-14. Both accidents were caused by the structural failure of the rudder posts above the upper hinge due to fatigue of the 1025 carbon steel material used in the rudder posts.
Besides the two primary accidents, there were five additional incidents of broken rudder posts reported between 1979 and the present, as documented by the FAA’s Airworthiness Concern Sheet. The FAA proposes replacing rudder posts made from 1025 carbon steel with those made from 4130N low-alloy steel, which is more durable and less prone to fatigue. The estimated cost for the replacement is approximately $3,000 per aircraft. The compliance time varies between two to five years depending on the category of the aircraft, with Category I aircraft having the shortest compliance period.
“The FAA’s action reflects the ongoing commitment to enhancing aviation safety standards. Similar directives are issued globally by other aviation regulatory bodies to address safety concerns and prevent accidents.”
Recent Developments
The FAA extended the comment period for the proposed AD from November 20, 2023, to February 20, 2024, to allow more time for public feedback and comments. On February 13, 2025, the FAA adopted the final rule for the airworthiness directive, making the rudder replacements mandatory for the affected aircraft. Organizations such as the Experimental Aircraft Association (EAA) and the EAA Vintage Aircraft Association (VAA) have filed comments opposing the broad scope of the AD and recommending alternative inspection and repair techniques instead of mandatory replacements.
The Aircraft Owners and Pilots Association (AOPA) is preparing comments for the AD and encourages affected members to provide their feedback. AOPA VP of Regulatory Affairs Murray Huling suggested that commenters provide recommendations for thorough inspection methods of the rudder posts as an alternative to mandatory replacement. The mandate will have significant implications for the owners and operators of the affected Piper aircraft, requiring substantial financial investment and maintenance efforts. It also highlights the importance of material selection and durability in aircraft design and maintenance.
Conclusion
The FAA’s mandate for rudder replacements on Piper aircraft underscores the critical importance of aviation safety. By addressing the issues of fatigue and corrosion in rudder posts, the FAA aims to prevent future accidents and ensure the airworthiness of these aircraft. The directive, while necessary, poses significant financial and logistical challenges for aircraft owners and operators.
Looking ahead, the aviation industry must continue to prioritize safety while also considering the practical implications of such mandates. The feedback from industry groups like the EAA and AOPA highlights the need for balanced approaches that ensure safety without imposing undue burdens. As technology and materials evolve, the industry must adapt to new standards and practices to maintain the highest levels of safety and reliability.

Turkish Airlines 777-300ER Wing Strike at Antalya Airport
A Turkish Airlines Boeing 777-300ER struck a radar antenna pole taxiing at Antalya Airport, prompting evacuation and a formal investigation.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by Hürriyet.
A Turkish Airlines (TK) Boeing 777-300ER sustained damage and prompted a passenger evacuation after its right wing struck a ground radar antenna pole while taxiing at Antalya Airport (AYT) on June 11, 2026.
The incident, which occurred at approximately 20:00 local time following Flight TK2430 from Istanbul, resulted in minor injuries among the passengers. According to official statements reported by Hürriyet, the widebody aircraft was maneuvering toward its parking position on Apron-1 when the collision occurred, leading to an immediate evacuation on the tarmac.
Conflicting passenger and injury reports
Following the evacuation, official sources provided conflicting figures regarding the number of passengers on board and the extent of injuries. In a public statement, Turkish Airlines Senior Vice President of Communications Yahya Üstün confirmed the evacuation, stating that 267 passengers were safely removed from the aircraft. The airline reported that one passenger sustained minor injuries and was in good health.
Conversely, the Turkey Ministry of Transport released a separate statement indicating a higher passenger count. The ministry reported that the aircraft was carrying 284 adult passengers and four infants. Furthermore, the government authority stated that three passengers suffered minor injuries during the event. Both entities confirmed that the aircraft, registered as TC-LKD, was towed to a parking area after the necessary safety checks and passenger removal were completed.
Investigation into the ground collision
A technical investigation into the ground collision has been initiated by the Turkey Ministry of Transport and the General Directorate of State Airports Authority (DHMI). The official cause of the incident remains under investigation.
While the airline noted the aircraft was approaching its parking position, preliminary remarks from the Ministry of Transport suggested the Boeing 777-300ER made contact with the radar pole after entering an incorrect taxiway line. Final determinations regarding the aircraft routing, ground control instructions, and the sequence of events will be established by the investigating authorities.

NTSB Final Report: Southwest Flight 4273 Turbulence Encounter
NTSB cites ATC communication delays and sector overload in Southwest Airlines turbulence event over Gulf of Mexico.

This is original reporting and analysis by AirPro News.
The National Transportation Safety Board (NTSB) has released its final report on a severe turbulence encounter involving a Southwest Airlines Boeing 737-700, detailing how rapidly developing convective weather and air traffic control communication delays factored into an event that seriously injured two people.
The April 3, 2024, incident aboard Southwest Airlines Flight 4273 over the Gulf of Mexico highlights the operational risks when severe weather systems intersect with technical limitations at air traffic control facilities. According to the NTSB investigation, the aircraft was navigating complex weather en route from New Orleans to Orlando when the encounter occurred, resulting in serious injuries to one flight attendant and one passenger, alongside minor injuries to a second flight attendant.
Weather conditions and the turbulence encounter
Flight 4273, operated by a Boeing 737-700 (registration N567WN) with 140 passengers and five crew members on board, was traveling from Louis Armstrong New Orleans International Airport (MSY) to Orlando International Airport (MCO).
At 11:55 UTC, a Convective Significant Meteorological Information (SIGMET) advisory was issued for the region, warning of cloud tops exceeding 45,000 feet.
At approximately 08:20 Eastern Daylight Time, the aircraft encountered severe turbulence over the Gulf of Mexico. The NTSB confirmed the aircraft itself sustained no damage during the event and the flight crew was able to continue the flight.
Air traffic control workload and technical limitations
The NTSB report outlines compounding factors at the Jacksonville Air Route Traffic Control Center (JAX ARTCC) that affected the flight routing through the weather system.
During the incident, the specific JAX ARTCC sector was managing a traffic volume that exceeded its target capacity of 20 aircraft.
This high workload was exacerbated by a technical limitation involving the facility communication infrastructure. The primary VHF antenna at JAX ARTCC had been rendered inoperative following a fire in October 2023. As a result, controllers were utilizing a temporary satellite relay connection to communicate with aircraft in the sector.
The NTSB determined this satellite relay introduced a 600-millisecond round-trip transmission delay, complicating timely communication between controllers and flight crews navigating the dynamic weather environment.
AirPro News analysis
We note that the findings in this final report underscore a critical vulnerability in the National Airspace System. When primary communication infrastructure fails, the fallback systems must be robust enough to handle high-stress, time-critical scenarios like severe convective weather deviation. A 600-millisecond delay might seem negligible in routine operations, but in a saturated sector where controllers are issuing rapid heading changes to keep aircraft clear of building storm cells, that latency degrades situational awareness and increases the risk of weather encounters. The NTSB documentation of this technical shortfall will likely prompt further scrutiny of contingency communication systems at major en route centers.

Sinkhole Closes Primary Runway at Tri-Cities Airport
A 20-ft-wide, 17-ft-deep sinkhole forced closure of Runway 5/23 at TRI on June 9, 2026, disrupting airline operations.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by WSMV by Li Cohen, Kingsport Times News, and official statements from the Tri-Cities Airport Authority.
A massive sinkhole measuring 20 feet wide and 17 feet deep forced the immediate closure of the primary commercial runway at Tri-Cities Airports (TRI) in East Tennessee on June 9, 2026, disrupting airline operations. The subsurface void was discovered beneath Runway 5/23, prompting airport officials to halt traffic on the strip while engineering teams assess the structural integrity of the pavement.
Airport personnel initially identified a surface condition requiring evaluation on the runway on Tuesday. Subsequent investigation by the Tri-Cities Airport Authority revealed the extensive 20-by-20-by-17-foot void, leading to an extended closure through at least June 10, 2026, according to official airport updates.
Operational impact and airline response
Runway 5/23 serves as the primary long runway for commercial flights at the Blountville facility. Its sudden closure has shifted the burden of operational decisions to individual air carriers, who must evaluate their ability to operate at the airport under current conditions.
Tri-Cities Airport Authority President and CEO Gene Cossey stated that airlines will determine whether to delay or cancel their scheduled flights. According to reporting by Kingsport Times News, Cossey advised passengers to check directly with their respective airlines for status updates before traveling to the terminal.
While the primary commercial strip is out of service, the airport’s secondary runway, Runway 9/27, remains open for operations. However, the shift in runway availability has required dispatchers and flight crews to recalculate performance data to ensure safe operations on the alternate surface.
Infrastructure repairs and geological context
Repair efforts commenced immediately on the evening of June 9. The airport authority emphasized that safety remains the primary concern during the restoration process and that the runway will remain closed until repairs meet regulatory standards.
“The airport will work to fix this problem as quickly as possible, but we always ensure the safety of the traveling public is our primary concern, and we will ensure that the repairs are made as quickly as we can while also ensuring complete safety,” Cossey said, as reported by Kingsport Times News.
Sinkholes are a documented geological hazard in East Tennessee. The region is characterized by karst topography, which consists of highly soluble carbonate rocks that can dissolve and create underground voids over time.
Similar infrastructure challenges have affected other major aviation facilities recently. On May 20, 2026, a sinkhole discovered near Runway 4/22 at New York’s LaGuardia Airport (LGA) forced a runway closure and caused widespread flight disruptions, according to reporting by WBIR.
AirPro News analysis
We note that runway closures due to sudden geological subsidence present unique challenges for airport operators, particularly at regional facilities with limited runway redundancy. While TRI’s Runway 9/27 remains active, its dimensions and weight-bearing capacity may restrict certain commercial operations or require payload penalties compared to the primary Runway 5/23. The rapid identification of the 17-foot-deep void highlights the critical importance of routine daily runway inspections in preventing potential aircraft incidents during takeoff or landing rolls. The timeline for reopening Runway 5/23 will likely depend on the stability of the surrounding soil and the extent of the required fill and repaving work.
