One of the new machines spewed debris over the weekend during a taxi test. The company is pulling the faulty engine off and taking it to a General Electric (NYSE:GE) facility in Cincinnati to be looked at.
The debris ignited a fire in the grass along the runway and temporarily diverted and delayed flights. It does not appear to be a fleet-wide problem, though.
The source of the malfunction hasn’t yet been determined, as a team will have to deconstruct the engine and examine every piece. It isn’t though to be severe enough that it would have brought down the machine if it had been in the air, though, since the plane was made to be able to fly with one engine, Reuters reports.
