AD FAA-2025-1355

The FAA is adopting a new airworthiness directive (AD) for certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes. This AD was prompted by the discovery of a gap between the trailing edge wing nut plates and leading edge aileron balance weights being less than the minimum required clearance. This AD requires replacing the affected left and right aileron fixed balance weights with reduced geometry fixed balance weights. The FAA is issuing this AD to address the unsafe condition on these products.
