Boeing 747s must now be checked for rust around their satellite antennas

The US aviation regulator wants all Boeing 747 airplanes to undergo regular inspections for corrosion around their satellite communication antenna plates. This means airlines operating these planes will have to add a new maintenance check to their schedules.

Corrosion on an antenna plate might seem minor, but it can lead to structural damage if left unchecked. This proposed rule means airlines will have to spend more on maintenance to keep older 747s flying safely. It also highlights the ongoing costs of maintaining aging aircraft fleets.
