Boeing 767 cargo planes must replace insulation that lets smoke into the cabin

US aviation regulators are ordering specific Boeing 767-300F cargo planes to replace insulation blankets. It turns out the original blankets did not fit properly, allowing smoke from the cargo hold to enter the main cabin.

This is a small, specific fix for a known safety issue. It means that a certain number of Boeing 767 cargo planes will need to be taken out of service to replace insulation. The change prevents smoke from reaching the main cabin, which is a critical safety improvement for the crew.
