Pratt & Whitney identifies CSeries engine problem

Aircraft engine maker, Pratt & Whitney has said a fault on the engines for Bombardier’s CSeries aircraft is caused by a seal in the oil system that would require a relatively minor adjustment, Reuters has reported. The company, a division of United Technologies Corp, makes the engine for Bombardier’s CSeries narrow-body plane, but the aircraft has been grounded since late May after a major engine failure in testing. Graham Webb, the company’s chief engineer for commercial engines, said it was a relatively minor adjustment for the CSeries engine. “We will have them back up and flying in the very near future but we have to ensure the validation is robust,” he said.
