Japanese airlines All Nippon Airways (ANA) grounded 5 of its 11 787 Dreamliners from Boeing Co. (NYSE: BA) following tests that indicate a risk of corrosion in the plane’s Rolls-Royce engines. Three planes have been repaired and are flying again while the other two await parts.
The Dreamliner, which carries a list price of $193.5 million, has suffered several problems since the first planes were shipped to ANA last year. A problem with the plane’s landing gear came to light shortly after ANA received the first planes last October and a delamination of the Dreamliners carbon-fiber fuselage was discovered early this year.
The engine problem in ANA’s plane was due to a faulty gearbox supplied by a division of United Technologies Inc. (NYSE: UTX). Engine-maker Rolls-Royce has also faced some problems with the engines it supplies to Airbus for its A380 aircraft.
