Power Bank Safety on Aircraft: Lessons from the Air Busan Fire
The Rising Concern Over Power Bank Safety on Aircraft
The recent fire on an Air Busan aircraft bound for Hong Kong has reignited concerns over the safety of power banks and other lithium-ion battery devices on flights. The incident, which occurred on January 28, 2025, at Gimhae International Airport in South Korea, injured seven people and forced the evacuation of 169 passengers and crew members. The suspected cause? A power bank stowed in an overhead locker. This event has prompted Air Busan to implement stricter regulations, banning the storage of power banks in overhead bins. But is this enough to ensure passenger safety, or is it merely a reactive measure?
Power banks have become an essential travel accessory, allowing passengers to charge their devices during long flights. However, their lithium-ion batteries pose significant safety risks, including the potential for overheating, short-circuiting, and even explosions. The aviation industry has long grappled with how to manage these risks, balancing convenience with safety. The Air Busan incident underscores the urgent need for stricter global standards and enforcement to prevent similar accidents in the future.
This article delves into the details of the Air Busan incident, explores the broader implications for the aviation industry, and examines expert recommendations for mitigating the risks associated with power banks on flights. We’ll also discuss the regulatory framework governing lithium-ion batteries on aircraft and the steps airlines can take to enhance passenger safety.
The Air Busan Incident: A Wake-Up Call
The fire on the Air Busan Airbus A321 was a stark reminder of the dangers posed by lithium-ion batteries. According to local media reports, the blaze was likely caused by a power bank stored in an overhead locker. The fire broke out just before takeoff, leading to the evacuation of all passengers and crew via inflatable slides. Seven people were injured, with one passenger remaining hospitalized. The incident has prompted Air Busan to ban the storage of power banks in overhead bins, requiring passengers to keep them in zipper storage bags under their seats or in seat pockets.
This measure, while precautionary, is more restrictive than existing international practices. Warren Chim Wing-nin, deputy chairman of the Hong Kong Institution of Engineers’ aircraft division, noted that the ban is a response to the recent accident but may not be necessary for all airlines. He emphasized the importance of further risk assessments by trade groups and carriers before expanding such measures globally.
The Air Busan incident is not an isolated case. In 2023, a power bank exploded on a Scoot Airlines flight from Singapore to Taipei, injuring two passengers. These incidents highlight the need for stricter safety protocols and better enforcement of existing regulations to prevent future accidents.
“Passengers should check their power banks to ensure they are in good condition and avoid bringing old ones on board. The internal insulator or wires inside older power banks could wear down over time, which could cause a short circuit and create a fire.” – Lo Kok-keung, retired engineering professor
Regulatory Framework and Industry Response
The International Civil Aviation Organisation (ICAO) and the International Air Transport Association (IATA) have established guidelines for the safe transport of lithium-ion batteries on aircraft. Power banks are classified as “spare lithium batteries” and are prohibited from checked luggage. They must be carried on board, with specific restrictions based on their watt-hour (Wh) rating. For instance, power banks with a Wh rating exceeding 100Wh are subject to additional limitations.
Hong Kong carriers like Cathay Pacific Airways and HK Express allow up to 20 spare batteries under 100Wh on board, while devices between 100Wh and 160Wh are limited to two. However, the implementation and enforcement of these guidelines vary significantly between airlines and regions. The Air Busan incident has prompted calls for stricter global standards and better enforcement to ensure consistent safety measures across the industry.
In response to the incident, Air Busan has implemented stricter rules regarding the storage of power banks on its flights. Other South Korean airlines, such as Eastar Jet, have also banned the storage of battery packs in overhead bins. These measures are part of a broader trend towards stricter regulation and safety protocols for portable electronic devices on flights.
Expert Recommendations for Passenger Safety
Experts like Lo Kok-keung and Warren Chim Wing-nin have offered several recommendations for passengers to minimize the risks associated with power banks on flights. Passengers should ensure their power banks are in good condition and from reputable brands. Older power banks are more prone to internal wear and tear, which can lead to short circuits and fires. Passengers should also keep power banks in their possession rather than stowing them away and avoid using them during flights.
Choi In-chan, a safety expert, suggests that airlines should check for portable chargers at the check-in counter and provide passengers with plastic bags to store them. This would allow cabin crew to easily monitor the status of power banks during the flight. Additionally, airlines should keep a list of passengers with charging devices to ensure proper oversight and management.
These recommendations, if implemented, could significantly reduce the risks associated with power banks on flights. However, they also highlight the need for better education and awareness among passengers about the potential dangers of lithium-ion batteries.
Conclusion
The Air Busan incident serves as a stark reminder of the risks posed by power banks and other lithium-ion battery devices on aircraft. While the airline’s decision to ban the storage of power banks in overhead bins is a step in the right direction, it is not a comprehensive solution. The aviation industry must adopt stricter global standards and better enforcement of existing regulations to ensure consistent safety measures across all airlines.
Passengers also have a role to play in minimizing these risks. By following expert recommendations and being mindful of the condition and storage of their power banks, they can help prevent accidents and ensure a safer travel experience for everyone. As the use of portable electronic devices continues to grow, the industry must remain vigilant and proactive in addressing the safety challenges they present.

Regulations & Safety
FAA Proposes Supersonic Noise Standard to Repeal 1970s Ban
The FAA announced noise-based certification standards for supersonic overland flight on June 30, 2026, targeting final rules by mid-2027.
The Federal Aviation Administration (FAA) has proposed a new noise-based certification standard for supersonic aircraft, initiating the formal regulatory process to repeal the 1970s ban on commercial supersonic flight over United States territory.
Announced on June 30, 2026, by U.S. Transportation Secretary Sean P. Duffy and FAA Administrator Bryan Bedford, the rulemaking aims to establish acceptable noise thresholds for overland flights. The proposal provides aerospace Manufacturers with the regulatory framework required to finalize next-generation supersonic designs that utilize quiet boom and “Mach cutoff” technologies.
Regulatory framework and timeline
The initial proposal focuses on noise-based certification standards during cruise flight. According to the FAA press release, the agency plans to introduce a second rule covering landing and takeoff noise standards later in 2026. The FAA has set a target date of mid-2027 to finalize both sets of rules.
U.S. Transportation Secretary Sean P. Duffy characterized the initiative as a move to safely enable the next quantum leap in aviation technology. FAA Administrator Bryan Bedford noted that advances in aerospace engineering, materials science, and noise reduction will eliminate the traditional sonic boom.
“This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports,” Bedford stated.
The White House Office of Science and Technology Policy (OSTP) is also involved in the initiative. OSTP Director Michael Kratsios stated that the updated rules will strengthen the industrial base and ensure the future of aviation is built in America.
Technological foundations and industry response
The June 30 announcement follows a series of preparatory steps by both regulators and the aerospace industry. On January 27, 2026, the FAA unveiled a new agency structure that included the creation of the Office of Advanced Aviation Technologies, a division specifically tasked with overseeing the integration of supersonic aircraft into U.S. airspace.
The technical basis for the new noise thresholds draws on data from the NASA and Lockheed Martin X-59 quiet supersonic research aircraft. The X-59 completed its First-Flight on October 28, 2025. The aircraft was explicitly designed to reduce sonic booms to a gentle thump, providing regulators with the acoustic data necessary to establish new overland flight standards.
Commercial developers have responded positively to the regulatory clarity. Boom Supersonic CEO Blake Scholl confirmed that the FAA rulemaking includes provisions for the “Boomless Cruise” or Mach cutoff approach. Boom has been demonstrating this operational concept with its Boom XB-1 test aircraft. Scholl described the FAA announcement as a major step toward the supersonic renaissance.
AirPro News analysis
We view the establishment of a definitive noise standard as the single most significant regulatory hurdle for the revival of commercial supersonic travel. For the past several years, manufacturers have been developing quiet supersonic technologies without a finalized target for acceptable noise levels. By defining the Certification standards, the FAA is shifting the primary challenge for companies like Boom Supersonic from regulatory uncertainty to engineering execution. The mid-2027 target for finalizing both cruise and terminal area noise rules sets a tight timeline, but it aligns with the development schedules of the next-generation supersonic aircraft currently in testing.

Pilatus PC-6 Crash in France Kills 11 on Skydiving Flight
A Pilatus PC-6 crashed near Nancy-Essey aerodrome on June 28, 2026, killing all 11 aboard in France’s deadliest skydiving accident in 30 years.
This is a developing story. Information may change as official details are released.
This article summarizes reporting by the Associated Press, Reuters, and CBS News, alongside official statements from the Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA).
Eleven people sustained fatal injuries on June 28, 2026, when a Pilatus PC-6/B2-H4 Turbo Porter Commercial-Aircraft crashed shortly after takeoff during a skydiving flight in northeastern France.
The Accident occurred at approximately 09:00 UTC (11:00 local time) near the Nancy-Essey aerodrome (ENC/LFSN). According to French Transport Minister Philippe Tabarot, the event represents the deadliest general aviation accident involving skydiving operations in France in approximately 30 years. The Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA) has deployed four Investigations to the site to determine the circumstances of the crash.
Aircraft departure and impact
The aircraft, registered in Germany as D-FIPS and reportedly owned by Classic Wings GmbH, departed Nancy-Essey for a tandem skydiving excursion. Less than one minute after takeoff, the aircraft banked left and descended almost vertically, impacting a grassy area in the town of Tomblaine, approximately 300 meters from the runway.
The Meurthe-et-Moselle Prefecture confirmed that all 11 occupants died in the crash. The victims included one pilot, five skydiving instructors, and five students. Thierry Pechey, president of the Meurthe-et-Moselle branch of the Order of Independent Nurses, told CBS News that the students were local nursing colleagues participating in a first-time jump.
Local officials noted the aircraft crashed near a residential neighborhood and shopping center. Yves Séguy, Prefect of the Meurthe-et-Moselle department, told the Associated Press that the accident could have caused collateral casualties had the impact occurred just a few dozen meters away. No injuries on the ground were reported.
Safety investigation and witness reports
The BEA is leading the Safety investigation, working in coordination with the Paris Criminal Investigation Department and the Air Transport Gendarmerie Brigade (GTA). The official cause of the accident remains under investigation.
While the BEA has not confirmed any mechanical faults, Reuters reported that witnesses on the ground heard the aircraft engine noise stop suddenly before the descent. Hervé Féron, the mayor of Tomblaine, stated that the aircraft fell in an unexplained manner during its initial ascent.
French Interior Minister Laurent Nunez noted that families of the victims were present at the aerodrome and witnessed the accident, resulting in significant psychological trauma.
AirPro News analysis
We note that this accident follows another fatal skydiving flight earlier in June 2026 in Missouri, which resulted in 12 fatalities. While the two events involve different operators, aircraft types, and regulatory jurisdictions, the proximity of these high-fatality accidents will likely bring renewed regulatory scrutiny to general aviation skydiving operations globally. The Pilatus PC-6 involved in the Tomblaine accident was 35 years old, a common age for utility turboprops in the skydiving sector, where aircraft are subjected to high-cycle operations characterized by rapid ascents and descents. The BEA preliminary report will be critical in establishing the sequence of events following takeoff.

Light-Sport Aircraft Strikes CITIC Tower in Beijing
A Sunward SA 60L Aurora struck Beijing’s 528-meter CITIC Tower on June 26, 2026, breaching restricted airspace.
This is a developing story. Information may change as official details are released.
This article summarizes reporting by CNN by Steven Jiang, with additional reporting from Reuters, Forbes, the South China Morning Post, the Financial Times, and the Associated Press.
A domestically produced light-sport aircraft struck the upper floors of the CITIC Tower in Beijing’s Central Business District on June 26, 2026, triggering mass evacuations and a heavy police response in one of the world’s most tightly controlled airspaces.
According to CNN, the aircraft impacted the 528-meter (1,732-foot) skyscraper shortly before 10:00 UTC (6:00 PM local time), scattering debris onto the streets below. The incident represents a highly unusual breach of the restricted flight zones over central Beijing, which are strictly enforced to protect nearby government leadership compounds.
Flight trajectory and aircraft identification
The aircraft involved has been identified by the South China Morning Post as a Sunward SA 60L Aurora, a two-seat light-sport aircraft, bearing registration B-12PP. The exact number of occupants on board at the time of the crash has not been officially confirmed.
The Associated Press reported that the flight originated from an Airports approximately 50 kilometers (27 nautical miles) east of the Chinese capital at around 5:30 PM local time. Flight tracking data indicates the aircraft deviated from its standard operating area before entering the restricted airspace over the city center.
Ian Petchenik, a spokesman for Flightradar24, told Forbes that the aircraft type is typically utilized for pilot Training in the region east of Beijing. He noted that no possibilities regarding the nature of the flight can be ruled out at this stage of the Investigation.
Evacuations and official response
The collision prompted immediate evacuations of the 109-story CITIC Tower, also known as China Zun. Occupants reported fleeing the building rapidly, with one evacuee telling the South China Morning Post they left without personal belongings. Unverified eyewitness accounts provided to Reuters described the impact noise as louder than fireworks.
The Beijing Municipal Public Security Bureau quickly cordoned off the surrounding Central Business District. CNN noted that Chinese state media has not yet reported on the event, and images or videos of the crash are being actively removed from domestic social media platforms.
Official casualty figures remain pending, and the condition of the pilot or any potential passengers is currently unconfirmed. The Civil Aviation Administration of China (CAAC) and local authorities have not issued a formal statement regarding the cause of the crash, which remains under investigation.
Beijing airspace security context
The airspace over central Beijing is subject to stringent Regulations. The Financial Times highlighted that commercial flights routinely execute wide detours to avoid the city center, primarily to secure the Zhongnanhai compound, which houses the central government leadership just kilometers from the crash site.
This event follows recent regulatory actions by Beijing authorities to further tighten airspace controls. Last month, officials implemented new restrictions that effectively banned the sale and operation of consumer Drones within the capital, as reported by the Associated Press.
AirPro News analysis
We note that unauthorized incursions into central Beijing’s airspace by crewed aircraft are exceptionally rare due to the severe security protocols in place. The investigation by the CAAC will likely focus on whether the deviation from the training area was the result of mechanical failure, pilot incapacitation, navigational error, or an intentional act. The immediate censorship of the event on Chinese social media aligns with standard operational procedures by state authorities during high-profile domestic incidents, which may delay the public release of preliminary investigation findings.
