Description

The FAA is issuing a final rule superseding Airworthiness Directive (AD) 2021-22-12 for certain Honda Aircraft Company LLC Model HA-420 airplanes. The previous AD required removing and cleaning the inner diameter of the flap control pushrod assemblies and repetitively applying corrosion inhibiting compound (CIC). The new directive retains these requirements but also mandates replacing the flap control pushrod assemblies with improved corrosion-resistant designs that prevent interference with adjacent parts. This action addresses an unsafe condition that could lead to uncontrolled flap asymmetry and loss of airplane control.
