A Boeing 787 Dreamliner operated by Ethiopian Airlines caught fire at London’s Heathrow airport on Friday in a fresh blow for the US planemaker whose new model was grounded for three months after one high-tech battery caught fire and another overheated.
External scorching from the fire was located in a different part of the aircraft from the bays containing batteries and the cause of the fire was unknown.
Boeing shares closed down 4.7 percent at US$101.87, knocking US$3.8 billion off the company’s market capitalization after television footage showed the Dreamliner surrounded by firefighting foam at Heathrow.

Pictures of the plane at Heathrow showed an area just in front of the tail that appeared to be scorched.
The Dreamliner’s two batteries are in electrical compartments located low down and near the front and middle of the aircraft, while the visible damage to the Ethiopian plane appears to be on top of the fuselage, further toward the rear, according to video from the scene.
“A Boeing 787 Dreamliner suffered an onboard, internal fire,” a Heathrow spokeswoman said. “The plane is now parked at a remote parking stand several hundred meters away from any passenger terminals.”
Former US National Transportation Safety Board chairman Mark Rosenker said the Heathrow incident was extraordinary news coming so soon after the fleet had returned to service, but he cautioned against jumping to conclusions.
“It’s very early. No one knows where the fire started at this point,” Rosenker said, adding it could be something as simple as a coffee pot left on in a galley.
Boeing said it was aware of the fire and it had people on the ground working to uncover the causes of it.
The 787 is Boeing’s biggest bet on new technology in nearly 20 years. It cost an estimated US$32 billion to develop and Boeing plans to use hundreds of innovations such as its carbon fiber composite skin and electrical system to enhance other jets.
The plane which caught fire in London was the first of the 787 fleet to resume flying after the battery-related grounding.
“This is terrible for the Dreamliner, any event involving fire and that airplane is going to be a PR disaster for Boeing,” said Christine Negroni, an aviation writer and safety specialist based in New York, in a telephone interview.
“Because of the battery issue, the public is even more sensitive to events that happen to the Dreamliner. Even if they are normal, benign teething problems, that subtlety is going to be lost on the public,” she said.
Another Boeing Dreamliner operated by Thomson Airways returned to Britain because of technical issues on Friday as a precaution, TUI Travel said.
Ethiopian Airlines said its aircraft had been parked at Heathrow for more than eight hours before smoke was detected.
Richard Aboulafia, a senior aerospace analyst at the Teal Group in Virginia, said early evidence, including images of the jet, suggest the battery is not the issue because of the location of the fire.
Boeing’s 787 Dreamliner was grounded by regulators in January after batteries overheated on two of the jets within two weeks, including a fire in a parked Japan Airlines plane in Boston.
Boeing was forced to halt deliveries of the jet while it was grounded and airlines stopped ordering the plane during that period. Orders have since resumed and Boeing has logged 83 Dreamliner orders this year.
Hon Hai Precision Industry Co (鴻海精密) yesterday said that its research institute has launched its first advanced artificial intelligence (AI) large language model (LLM) using traditional Chinese, with technology assistance from Nvidia Corp. Hon Hai, also known as Foxconn Technology Group (富士康科技集團), said the LLM, FoxBrain, is expected to improve its data analysis capabilities for smart manufacturing, and electric vehicle and smart city development. An LLM is a type of AI trained on vast amounts of text data and uses deep learning techniques, particularly neural networks, to process and generate language. They are essential for building and improving AI-powered servers. Nvidia provided assistance
DOMESTIC SUPPLY: The probe comes as Donald Trump has called for the repeal of the US$52.7 billion CHIPS and Science Act, which the US Congress passed in 2022 The Office of the US Trade Representative is to hold a hearing tomorrow into older Chinese-made “legacy” semiconductors that could heap more US tariffs on chips from China that power everyday goods from cars to washing machines to telecoms equipment. The probe, which began during former US president Joe Biden’s tenure in December last year, aims to protect US and other semiconductor producers from China’s massive state-driven buildup of domestic chip supply. A 50 percent US tariff on Chinese semiconductors began on Jan. 1. Legacy chips use older manufacturing processes introduced more than a decade ago and are often far simpler than
STILL HOPEFUL: Delayed payment of NT$5.35 billion from an Indian server client sent its earnings plunging last year, but the firm expects a gradual pickup ahead Asustek Computer Inc (華碩), the world’s No. 5 PC vendor, yesterday reported an 87 percent slump in net profit for last year, dragged by a massive overdue payment from an Indian cloud service provider. The Indian customer has delayed payment totaling NT$5.35 billion (US$162.7 million), Asustek chief financial officer Nick Wu (吳長榮) told an online earnings conference. Asustek shipped servers to India between April and June last year. The customer told Asustek that it is launching multiple fundraising projects and expected to repay the debt in the short term, Wu said. The Indian customer accounted for less than 10 percent to Asustek’s
Gasoline and diesel prices this week are to decrease NT$0.5 and NT$1 per liter respectively as international crude prices continued to fall last week, CPC Corp, Taiwan (CPC, 台灣中油) and Formosa Petrochemical Corp (台塑石化) said yesterday. Effective today, gasoline prices at CPC and Formosa stations are to decrease to NT$29.2, NT$30.7 and NT$32.7 per liter for 92, 95 and 98-octane unleaded gasoline respectively, while premium diesel is to cost NT$27.9 per liter at CPC stations and NT$27.7 at Formosa pumps, the companies said in separate statements. Global crude oil prices dropped last week after the eight OPEC+ members said they would
