An auxiliary battery ignited on a Scoot Airlines flight from Hong Kong to Singapore.

Fortunately, no human or gas damage occurred as the crew succeeded in extinguishing the fire immediately.

According to local media The Straits Times, when TR939 from Hong Kong to Singapore was about to land on the evening of the 22nd, the smell and smoke of getting on board was detected. It was ignited by a secondary battery in the seat.




The crew, who immediately ran, succeeded in extinguishing the fire using a fire extinguisher and water.

One passenger shared a photo that found soot marks on the wall of the cabin during the getting off.

Netizens who saw this said "It's scary because the gas seems to have been pierced," but others pointed out that it's impossible, saying "If it had actually been pierced, the cabin pressure would not have been maintained."




The video publisher explained that the crew carried the black bag to the bathroom with protective gloves, ice and fire extinguishers. Passengers were informed of the fire only after landing and claimed to have experienced anxiety and inconvenience from the smell of smoke and chemicals.

"The small flame on board was from an overheated auxiliary battery," Scoot said in a statement. "The crew immediately extinguished, and no injuries were reported.' The aircraft landed safely in Singapore at 9:06 p.m., and the passengers got off after firefighters and medical personnel came on board to check their safety.

Scoot apologized to passengers who suffered inconvenience in the accident, stressing that the safety of passengers and crew members is the top priority.




Meanwhile, Scoot and its sister Singapore Airlines have banned the use of auxiliary batteries on board since April, and have not allowed charging through USB ports. Other airlines, including Air China, Hong Kong Airlines, AirAsia, and Thai Airways, are implementing similar bans due to a recent series of auxiliary battery fires in aircraft.
