Japan’s All Nippon Airways said on Monday it grounded part of its fleet of 787 Dreamliners after tests revealed a risk of engine corrosion, but Boeing Co, the aircraft’s manufacturer, said it does not expect the timing of deliveries of the jetliner to be affected.
The engines on the ANA planes, Trent 1000s, were supplied by Rolls-Royce, which said it was replacing a component on a number of its engines.
ANA, the launch customer for the 787, the world’s first passenger jet built mainly from lightweight carbon fiber, said the action stemmed from a flawed process that could leave part of its UK-manufactured engines vulnerable to early corrosion.
The airline grounded five of its 11 Dreamliners, but three of the twinjet airplanes have been fixed and are flying again. The other two are waiting for parts from Rolls-Royce and could be out of action for a few weeks, an ANA spokesman said.
