ADDIS ABABA: Ethiopian Airlines yesterday became the world’s first carrier to resume flying Boeing Co’s 787 Dreamliner passenger jets, landing the first commercial flight since the global fleet was grounded three months ago following incidents of overheating in the batteries providing auxiliary power.
The flight from Addis Ababa to Nairobi was the first since regulators grounded all Dreamliners on January 16 after two lithium-ion battery meltdowns that occurred on two jets with other airlines within two weeks that month.
US regulators approved a new battery design last week, clearing the way for installation and a resumption of Dreamliner flights by airlines around the world. The battery faults raised fears of a possible mid-air fire, drawing worldwide attention to Boeing and denting the reputation of its flagship plane.
“I wasn’t aware that I was going to be on the 787 Dreamliner until on my way to the airport. It was a good service and the flight was pleasant,” said Senait Mekonnen, an Ethiopian restaurateur, moments after the plane landed.
The fully booked flight arrived at Nairobi’s Jomo Kenyatta International Airport just after 9.30 GMT, with passengers giving the crew a round of applause upon landing. The grounding of the Dreamliner fleet has cost Boeing an estimated $600m, halted deliveries of the aircraft and forced some airlines to lease alternative planes.
The Dreamliner cost an estimated $20bn to develop and represents a quantum leap forward in design, offering a 20 percent reduction in fuel burn and added cabin comforts such as higher humidity, larger windows and modern styling.
But by sparking fears of a dangerous mid-air fire, the battery problems drew worldwide attention to both aircraft safety and the technology behind lithium-ion batteries, which are widely used in laptops, mobile phones, electric cars and other products.
The scrutiny turned from what are often called normal “teething pains” for a new plane into a serious crisis for Boeing. As the plane goes back into service, what caused the fire is still unknown.
Boeing spent thousands of hours and millions of dollars redesigning the battery system, drawing on its vast staff of engineers and experts in everything from fighter planes to rockets and satellites. The changes include a revamped battery less prone to heat build-up, a redesigned charger and a stainless-steel enclosure capable of withstanding an explosion and equipped with a metal exhaust tube to vent fumes and gases outside the jet, if the battery overheats.
United Airlines said it will begin commercial flights on May 31. All Nippon Airways plans to conduct its first test flight of the revamped 787 today. Ethiopian Airlines previously said its fleet did not suffer any of the technical glitches experienced by other Dreamliner jets, though it withdrew the planes from service to undergo the changes required by the Federal Aviation Administration.
