SEOUL—South Korea’s Air Busan will not allow passengers to keep power banks in luggage stored in overhead cabin bins, which, on Tuesday, was called a preemptive measure after one of its planes was engulfed in flames last week.
An investigation led by South Korean authorities into the fire has begun, but no cause has yet been determined. Air accidents are nearly always caused by a combination of factors, according to experts.
Passenger carry-on bags inspected at boarding gates and found not to contain power banks will be tagged and then allowed in overhead luggage bins, in measures set to begin on Friday on trial routes, before expanding to all flights.
Any power banks should be kept with passengers so any overheating, smoke, or fire can quickly be spotted and dealt with.
Air Busan said the changes, which will also include additional crew fire training and fire containment equipment on board, were in response to an increase in the number of power banks overheating.
The fire, which began on Jan. 28 while preparing for departure to Hong Kong, was first detected by a flight attendant in an overhead luggage bin on the rear left-hand side of the plane, Air Busan has said. All on board were evacuated safely.
