Thai B773 at Bangkok on Oct 20th 2019, rejected takeoff due to uncontained engine failure
Last Update: October 24, 2019 / 10:37:55 GMT/Zulu time
The airline reported the aircraft was taking off from Bangkok when the left hand engine failed prompting the crew to reject takeoff. It was found the aircraft needs repair, no spare aircraft was immediately available, hence the passengers were taken to hotels. A replacement aircraft departed later the day.
A replacement Boeing 777-300 registration HS-TKK reached Zurich with a delay of 12 hours.
Late Oct 23rd 2019 the FAA released Emergency Airworthiness directive EAD-2019-21-51 stating the EAD was prompted by "by an event that occurred on October 20, 2019, in which a Boeing Model 777-300ER airplane powered by GE GE90-115B model turbofan engines experienced an uncontained high-pressure turbine (HPT) failure that resulted in an aborted takeoff. Debris impacted the aircraft fuselage and the other engine. Uncontained HPT failure, if not addressed, could result in release of high-energy debris, damage to the engine, damage to the airplane, and possible loss of the airplane." The EAD requires operators of GE90-115B engines with certain engine serial numbers to remove from service the Interstage Seal, part number 2505M72P01 with serial numbers GWN0TCL3, NCE062LD, NCE254LC, NCE314KU, NCE374LB, NCE527KT, NCE777LD, or NCE994KW within 25 cycles based on the GE Alert Service Bulletin GE90-100 S/B 72-A0826, dated October 23, 2019.
