A specific airplane model needs its pilot seats inspected, or replaced

The US aviation regulator is requiring inspections of pilot and co-pilot seats in certain Tecnam P-Mentor airplanes. This is because the seat locking mechanism failed in one of these planes. Owners must inspect the seat rails repeatedly, or replace the seat entirely.

This is a very specific, small-scale safety directive. It affects a single model of airplane from one manufacturer. These kinds of directives are common in aviation, where even minor failures can have serious consequences. The FAA is acting to prevent future accidents by mandating a fix for a known problem.
