Back on the safety issue....
The FAA issued an AD removing 8 GE90-115B engines from service.
The AD says the other engine was also damaged by the liberated turbine...
This emergency AD was prompted 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.
