On October 20th 2019 Thai Airways flight TG970, operated by a Boeing 777-300ER HS-TKL “Sunanda”, suffered an uncontained engine failure of its left engine while taking off from runway 01L at Bangkok.

Thai Airways says the aircraft had been rolling for take-off when the left-hand General Electric GE90 powerplant failed, prompting the crew to abort the departure.

The aircraft, HS-TKL, is 7.1 years old; the Boeing B777-300ER took its first flight on the 24th of September 2012 and was delivered to Thai on the 30th of October 2012. The cabin configuration is C42Y306 and the aircraft equips 2 GE90-115B engines.

Flight TG970 from Bangkok (BKK) to Zurich (ZRH) planned to take off at 01:30 on October 20th. After the engine failure, Thai Airways arranged a replacement flight, TG970D, using another 777, HS-TKK; leaving Bangkok at 13:00 with a 12-hour delay it arrived Zurich at 19:08. This caused TG971 to be delayed by around 9 hours.
