Boeing 737 Max escape slides must be inspected on more planes

US aviation regulators are expanding a mandatory inspection for escape slides on certain Boeing 737 airplanes. This means more airlines will have to check and potentially replace these parts on their planes.

Airlines operating specific Boeing 737 models, including the 737-8 and 737-9, now have a broader mandate to inspect and replace escape slides. This expands a previous directive that only covered some of these planes. The change means more planes will undergo checks for a potential safety issue.
