South Korea's Air Busan will not allow passengers to keep power banks in luggage stored in overhead cabin bins, in what on Tuesday it called a preemptive measure after one of its planes was engulfed in flames last week.

South Korean officials are launching an investigation into the cause of the fire that engulfed an Air Busan passenger plane while awaiting takeoff at Busan's Gimhae International Airport, with some eyewitness accounts leading to speculation that a portable power bank may have caused the blaze.

The fire broke out in the back of the cabin, officials said. All 176 people on board, including passengers and crew members, were evacuated, some with minor injuries.

Passengers evacuated from an Air Busan plane that was engulfed in flames this week at a South Korean airport will have their checked baggage returned to them, after authorities on Friday deemed the jet safe for a full investigation.

SEOUL -- As authorities investigate last week's fire on an Air Busan plane, South Korean media reports suggest that the cause may have been a portable power bank or electronic device in an overhead bin, spurring calls to regulate where carry-ons can be placed.

A South Korean airline no longer allows portable power banks in baggage stored in overhead bins, citing lithium-battery fire risk.

An airline from South Korea is introducing a ban on carrying power banks in carry-on luggage. This is a consequence of a plane fire on the runway in January. Air Busan, a South Korean airline, has announced a ban on carrying power banks in carry-on luggage placed in the overhead bins.

Hong Kong expert says expansion of measure to other airlines will depend on further risk assessments by trade groups and carriers.
