Boeing 787s must be inspected for misaligned stabilizer pins

US aviation regulators are proposing new inspections for certain Boeing 787 airplanes. This means airlines operating these planes will need to check for misaligned horizontal stabilizer pins and fix them if found.

This proposed rule means airlines will have to ground planes for inspections, which costs money and reduces available aircraft. It points to a potential manufacturing quality control issue at Boeing's final assembly line for a critical flight control component. This kind of issue can lead to significant operational disruptions for airlines and safety concerns for passengers.
