The first Boeing 787 prototype had to make an emergency landing at Grant County International Airport at Moses Lake, Wash., after test pilots lost thrust on one of the airplane’s Rolls-Royce Trent 1000 engines. Boeing and Rolls-Royce determined that a faulty pressure-sensing component led to the loss of power, Boeing Commercial Airplanes vice president of marketing Randy Tinseth wrote in his blog yesterday.
ZA001 returned to Boeing Field Sunday morning after the flight test team located replacement parts and sent them along with “the right crew” to Moses Lake to start maintenance activity on Saturday. After completing repairs later that day, Boeing ran the engines and encountered no anomalous readings.
“So, Sunday morning, we flew home,” wrote Tinseth. “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,” Tinseth concluded.
