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.

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

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.

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.

The Airbus A321 plane was engulfed in flames as it prepared to take off for Hong Kong from an airport in Busan, South Korea.

Shares of Air Busan dropped on Friday, after a plane belonging to the budget carrier caught fire earlier this week.
