All 169 passengers and seven crew members were evacuated from the Airbus A321ceo using emergency slides after the fire broke out on Tuesday, with only a few minor injuries, Air Busan said.
The fire, which began as the single-aisle jet was preparing for departure to Hong Kong, was first detected by a flight attendant in an overhead luggage bin in the rear left-hand side of the plane, an Air Busan spokesperson told Reuters.
Authorities on Friday conducted a risk assessment of the plane, which still had a large amount of fuel and oxygen onboard. The burned-out jet remains on the tarmac at Gimhae International Airport in the southern city of Busan.
The transport ministry on Friday said the 16,280kg of jet fuel do not need to be offloaded, and other hazardous materials such as oxygen tanks will be secured. The plane will be covered by a canopy to protect it during the inspection, which will begin on Monday.
Baggage in the cargo hold was removed on Friday, the ministry said.
The incident came a month after the deadliest air disaster on South Korean soil, when a Jeju Air plane crashed on Muan Airport's runway as it made an emergency belly landing, killing all but two of the 181 people on board.
Air Busan's single-aisle 17-year-old plane has burnt out holes along the length of the fuselage roof. Its wings and engines were not burned, a transport ministry statement said.
South Korea's Aviation and Railway Accident Investigation Board is leading the investigation, and was joined on Thursday by representatives of France's BEA air accident investigation agency. France is the state of design for Airbus planes.
Budget airline Air Busan is part of South Korea's Asiana Airlines, which in December was acquired by Korean Air.
