Key Takeaways:

The FAA has issued an Airworthiness Directive (AD), effective March 20, mandating the replacement of 1025 carbon steel rudders on specific Piper aircraft with more durable 4130N low-alloy steel rudders.
This safety measure follows two nonfatal accidents linked to rudder post failures caused by fatigue and corrosion.
The AD will impact an estimated 31,000 vintage high-wing Piper aircraft, including J-series Cubs and PA-22 Tri-Pacers, over the next 2-10 years.
Aviation groups like AOPA and the Short Wing Piper Club have opposed the AD due to concerns about cost and implementation but are actively seeking alternative methods of compliance (AMOCs).

The FAA has issued a final airworthiness directive (AD) requiring the replacement of rudders on specific Piper series aircraft.

The AD, effective March 20, addresses safety concerns stemming from reports of rudder failures due to fatigue and corrosion in rudder posts made from 1025 carbon steel. Under the new requirements, these components must be replaced with more durable 4130N low-alloy steel rudders.
