A recent fire incident involving an Air Busan aircraft preparing to depart from Gimhae International Airport, South Korea has raised concerns about the safety of lithium-ion batteries on commercial flights.
The 28 January 2025 incident saw all 176 passengers and crew evacuated safely, though some sustained minor injuries. With all passengers seated in the aircraft, flames had erupted in an overhead compartment.
The fire occurred on Air Busan flight BX391, operated by an Airbus A321-200 aircraft. The flight was preparing to push back for departure to Hong Kong when the fire broke out. While the official investigation is still underway, a portable lithium-ion battery is strongly suspected to be the culprit.
Emergency Evacuation of Air Busan A321
Air Busan flight was preparing for departure when smoke began billowing from an overhead storage compartment towards the read of the passenger cabin.
Crew members immediately initiated evacuation procedures, ensuring the safe removal of everyone on board. Initial reports have suggested the source was a passenger’s personal electronic device. Typically, it contained a lithium-ion battery, which may have malfunctioned and overheated, triggering the fire.
Eyewitness accounts describe a rapid escalation of smoke and flames. The incident highlights the potential danger these batteries pose in the confined environment of an aircraft cabin.
Flight attendants attempted to extinguish the flames with onboard fire extinguishers. However, the intensity of the fire and the dense smoke hampered their efforts.
The prompt evacuation decision, however, undoubtedly averted a potentially disastrous outcome.
Investigators will examine the precise cause of the fire, focusing on the specific battery involved, its condition, and its storage.
Authorities will likely examine whether the battery met safety standards and if there were any contributing factors that exacerbated the situation. The findings of this investigation will be critical in informing future regulations and preventative measures.
The Concern of Lithium-Ion Batteries
This isn’t the first time lithium-ion batteries have been implicated in aircraft fires. Numerous incidents involving personal devices and cargo shipments have raised red flags within the aviation industry.
These events have prompted calls for stricter regulations regarding the transportation of lithium-ion batteries, particularly in bulk. The Air Busan fire is likely to intensify this debate and may lead to more stringent screening procedures for carry-on electronic devices.
The incident also serves as a timely reminder for passengers about the potential hazards associated with lithium-ion batteries.
Passenger Awareness
Passengers are urged to handle these devices with care, avoid storing them in checked baggage, and be aware of the signs of battery malfunction, such as overheating, swelling, or unusual odors. Airlines are likely to reinforce their communication with passengers about the safe handling and transportation of these devices.
This incident highlights the inherent risks associated with these ubiquitous power sources, particularly when transported on airplanes.
Lithium-ion batteries, while powering everything from smartphones to laptops, are classified as hazardous materials due to their potential for thermal runaway, which can lead to fires or explosions.
Regulations already prohibit these batteries in checked baggage, but they are often permitted in carry-on luggage, albeit with specific guidelines. This incident raises questions about the efficacy of current regulations and the need for increased passenger awareness.
Finding a balance between facilitating the use of these essential devices and ensuring passenger safety remains a significant challenge. The results of the ongoing Air Busan investigation will be closely watched.
