All Nippon Airways returned to service the last of five grounded Boeing 787s on July 30, a little more than a week after Rolls-Royce discovered a defect in a batch of Trent 1000 engines installed in the airplanes. ANA had to ground nearly half of its 11 Dreamliners over the weekend of July 21 and 22 after the engine manufacturer found some “minor” corrosion within an external gearbox during product development testing.
