The first 787 - ZA001 - returned from Moses Lake Sunday morning after landing there on Friday.
Our flight test pilots had touched down at the Grant County International Airport after they experienced an uncommanded loss of thrust in one of the engines. It was an opportunity to really see the best of Boeing kick into gear. Teaming with Rolls-Royce, we determined that the issue had to do with a pressure-sensing component within the engine.
We located replacement parts and then got the parts and the right crew to Moses Lake - beginning the maintenance activity on Saturday. Later that day, we ran the engines to confirm that the replacement had been done correctly and that there were no anomalous readings.

So, Sunday morning, we flew home. The airplane is going through the maintenance and pre-flight work that would have been done had it arrived back at Boeing Field on Friday evening. I can tell you that ZA001 will soon return to flutter testing.
It’s a great tribute to the team that they completed the analysis, maintenance activity and testing in such short order. This is what happens during flight testing - and our plan accommodates such events.
We deal with issues and we keep going.
