I found this interesting. This is a different airline, Korea’s other airline, but it is also a Boeing 777. This just happened a few days ago:
B777 engine failure sparks concerns
By Nam Hyun-woo
The emergency landing of a Korea Air jet has called the safety of the B777-300ER passenger aircraft into question. Passengers are becoming concerned about the recurring safety problems of the aircraft.
Koreas transportation authorities said that an engine problem caused the incident.
On July 2, the jet, bound for Incheon International Airport from Chicago with 273 passengers on board, made the emergency landing at a far eastern Russian airport after only seven hours of flight.
All passengers and crew members disembarked safely and the plane returned to its original destination on July 3 at 6:40 a.m. (KST), 14 hours later than the estimated time of arrival, with another aircraft sent by the carrier three hours after the jet touched down.
The captain of the plane reported to the authorities of Anadyr Airport (Ugolny Airport) in Siberia, Chukotka, that the oil pressure of the left engine suddenly plunged, compelling it to make the emergency landing at around 2 p.m. (KST), according to Korean Air.
After engineers of Korean Air replaced the malfunctioned left engine, Koreas Ministry of Land, Infrastructure and Transport and the carrier launched an investigation into the incident and found the gearbox in the engine, built by General Electric (GE), was the reason for the problem.
