Glider owners must check a specific bearing or their planes cannot fly

The US aviation regulator proposes a new rule for certain Schempp-Hirth gliders. Owners must inspect a specific part in the tailplane and replace it if it is the wrong type.

A small part in the tail of a glider can break, which makes the glider unsafe. This rule means owners must fix the problem or their gliders cannot legally fly. This is a standard safety update for a specific aircraft model.
