The plane was grounded by Asiana Airlines on Monday when workers discovered oil leaking from an engine at the Los Angeles International Airport. The plane had been readying for a flight to South Korea when the problem was noticed, Reuters noted.
Passengers were transferred to another plane, but had to wait 17 hours to make their flight.
This is the second Asiana plane to suffer an oil leak. In early June, another of the airline’s fleet of Boeing 777s experienced oil leaking from an engine at San Francisco’s airport, forcing a delay.
Just over a month later, an Asiana-operated Boeing 777 crash landed at San Francisco’s airport, killing three passengers and injuring more than 180. Investigators are looking at possible pilot error in that incident.
Last week, Boeing shares plunged after a Boeing 787 Dreamliner caught fire at London’s Heathrow Airport. The Dreamliners were grounded earlier this year after a series of incidents linked to their lithium-ion batteries.
Despite the news, shares of Boeing rose modestly in Wednesday morning trading.
