Boeing 787s need more inspections for leaky water lines above electronics

The US aviation regulator is proposing new rules for Boeing 787-8 airplanes. These rules require more inspections for missing or damaged sealant and tape around water lines above the electronics bays. This means airlines will have to check more places on these planes to prevent water leaks from damaging critical equipment.

Water leaks in aircraft are a known problem, especially when they drip onto sensitive electronics. This proposed rule means airlines will have to spend more time and money on maintenance to find and fix these potential leak points. It also suggests that previous fixes were not enough, and some planes left the factory with problems.
