A fire incident involving Air Busan at Gimhae International Airport has raised serious concerns over lithium-ion battery safety on flights. The incident, which took place on January 28, 2025, saw flight BX391, operated by an Airbus A321-200, preparing to depart for Hong Kong when flames erupted from the overhead compartment. Fortunately, all 176 passengers and crew were evacuated safely, though seven individuals suffered minor injuries.
The fire broke out just before 10:30 p.m. local time. Eyewitness accounts described thick smoke billowing from the overhead compartment toward the rear of the passenger cabin. The crew took immediate action, initiating emergency procedures to evacuate everyone on board, utilizing inflatable slides to facilitate the exit as rapid smoke and flames escalated.
Initial investigations suggest the fire may have stemmed from a personal electronic device potentially carrying a lithium-ion battery. Reports indicate this is not the first occurrence of such fires linked to these batteries, raising red flags within the aviation industry. Authorities understand the growing concerns surrounding the use of lithium-ion batteries, which are commonly found in devices like smartphones and laptops.
The scene of the incident saw passengers escaping as fire crews responded quickly to extinguish the flames. Video footage showed passengers rushing away from the aircraft using the emergency slides, with fire engulfing parts of the plane.
“Our priority is the safety of our passengers and crew,” said Air Busan, as they confirmed the rapid response of their staff during the emergency. Airbus, the plane manufacturer, also announced their cooperation with the investigations spearheaded by the South Korean transportation ministry and the French Bureau for the Investigation and Analysis for Civil Aviation Safety.
The joint probe aims to determine the fire's origin, with investigators expected to focus on the rear section of the aircraft where the initial flames were reported. The investigation will include examining the specific battery involved, alongside any other items stored within the overhead compartment. Safety officials have prevented access to the fuselage for most individuals, ensuring the integrity of the investigative process.
The incident emphasizes the recognized risks of lithium-ion batteries. They are classified as hazardous materials due to their potential for thermal runaway, which can lead to fires or explosions. While air travel regulations already prohibit transporting these batteries as checked baggage, they are often allowed under specific guidelines for carry-on luggage, creating growing safety concerns.
This fire incident is set to recalibrate the conversation around current regulations for lithium-ion batteries on commercial flights. Previous incidents involving these batteries have already spurred discussions for enhanced regulations, and the latest incident involving Air Busan is likely to push those discussions forward. Experts may call for more stringent screening and handling measures for carry-on electronic devices.
Passengers are advised to be cautious, handle their devices carefully, and remain vigilant for signs of battery malfunction. Symptoms to watch for include overheating, swelling, or unusual odors. Airlines may amplify communication efforts, educating passengers about safe handling of electronic devices.
With the Air Busan incident highlighting the inherent risks associated with the ubiquitous lithium-ion batteries, aviation authorities will likely continue evaluating safety measures to prevent future occurrences. The results of the joint investigation will play a significant role not only for Air Busan but for the entire industry, ensuring passenger safety remains at the forefront of air travel.
The investigation is still underway, with officials promising to provide updates as they gather more information. For now, enhanced awareness surrounding the potential hazards posed by lithium-ion batteries remains imperative.
