Small aircraft now get a permanent fix instead of endless maintenance — first structural change to this design in 3 years

The FAA is replacing a temporary fix (repetitive cleaning and coating) with a permanent one (new parts that resist corrosion). This means Honda HA-420 aircraft owners stop paying for recurring maintenance on the same problem and can treat it as solved.

For three years, owners of these small jets had to keep cleaning and re-coating the same flap control parts because the originals corroded. This directive ends that cycle by requiring a swap to parts that don't need the maintenance. It's a small structural shift: from managing a known defect indefinitely to eliminating it once.
