Boeing 777s need inspections for faulty wiring that can cause arcing

The US aviation regulator proposes a new rule requiring inspections of certain Boeing 777 airplanes. This is because reports show chafing and arcing damage on the wiring for the sidewall lights.

This proposed rule means airlines operating specific Boeing 777 models will have to add a new inspection to their maintenance schedules. The inspections aim to prevent electrical arcing, which can lead to fires or other system failures during flight. This is a routine safety measure, but it adds to the operational costs for airlines.
