Qatar Airways has taken one of its Boeing 787 Dreamliners out of service following a "minor" issue in the latest problem to hit the aircraft.
The plane was grounded after smoke was seen near an electrical panel on the aircraft, reports Reuters.
Qatar Airways said no flights were cancelled as a result but that Qatar Airways was resolving the issue.
According to web-tracking service Flightaware, the aircraft, registered as A7-BCB, has not flown since Sunday, an unusually long downtime for a long-haul jet.
Indian aviation regulators are also investigating an oven that overheated and caused smoke in an Air India Dreamliner this week.
Japan’s ANA on Friday found damage to the battery wiring on two 787 locator beacons.
This latest series of incidents adds to the concern over the new Boeing aircraft, which came back into service in May following a four-month grounding over battery fires.
A Japan Airlines Dreamliner was forced to return to Boston airport earlier this month after a mechanical indicator alert came on mid flight.
Days earlier an Ethiopian Airlines 787 caught fire while parked at London Heathrow and Thomson was forced to turn back one of its 787s traveling from Manchester to Orlando after experiencing a mid-flight technical issue, see previous story.
