Airbus planes need a new inspection for a wrongly installed pin

The US aviation regulator proposes a new rule for certain Airbus Canada airplanes. It requires a detailed visual inspection of a specific pin in the horizontal stabilizer trim actuator to ensure it was installed correctly.

This is a small, specific fix for a manufacturing error. It means airlines operating these planes will have to ground them for inspections, which costs money and time. The issue is about a critical part that helps control the plane's pitch, so safety is the main concern.
