Newest Aircraft Carrier Breaks Down During Sea Trials

USS Ford underway for sea trials …

An article in Popular Mechanics said the the USS Ford had to return early from sea trials because of an overheating thrust bearing on one of the four main engines. Bloomberg reported that:

“inspection of the parts involved in the January 2018 incident revealed improperly machined gears at GE’s facility in Lynn, Massachusetts as the ‘root cause.'”

Is “improperly machined gears” a root cause? That would be a Causal Factor and the start of a root cause analysis in the TapRooT® System. And why wasn’t the “improper” machining detected prior to installation and sea trials?

Here is some footage of sea trials (including a brief glimpse of one main shaft turning).
