Some ATR airplanes must get new tail parts after a factory used the wrong material

The US aviation regulator is ordering inspections and replacements for certain ATR airplanes. This is because a factory used the wrong material for a part connecting the vertical and horizontal tail fins.

Aviation safety relies on strict manufacturing standards. When a factory uses incorrect materials, it can compromise the structural integrity of an aircraft. This order means airlines operating these specific ATR models must now spend money and time to ensure their planes are safe.
