ATR planes get mandatory inspections for a critical flap part

US aviation regulators now require specific inspections for all ATR42-200, -300, and -320 airplanes. This means operators must check a critical part of the flap system for wear and fix it if needed.

This rule prevents a known mechanical failure on a specific type of regional aircraft. It ensures that a part prone to wear, which could cause flight control issues, is regularly checked and repaired. This is a standard safety update, not a change to how aircraft are generally certified or maintained.
