Shares in the aircraft manufacturer, Boeing, have fallen after a 787 Dreamliner suffered a fuel leak.
It came a day after another Boeing Dreamliner belonging to Japan Airlines had an onboard fire just minutes after touching down in the US city of Boston.
These are not the first problems for Boeings Dreamliner fleet since it first entered service in October 2011.
But the latest incidents will be a worry to the manufacturer, the airlines and their passengers.
