Boeing must inspect 787 horizontal stabilizers for assembly errors

US aviation regulators are ordering Boeing to inspect certain 787 airplanes. This is to check for misaligned parts in the horizontal stabilizer, which helps control the plane's pitch.

This is a mandatory inspection for a specific set of Boeing 787s. It means airlines operating these planes must take them out of service to perform checks for potential manufacturing defects. The FAA is acting to prevent a safety issue before it causes an accident.
