GE Aviation has found what it is reporting to be unexpected wear in a part for its new engine for the new Boeing 777X passenger plane.
This will mean a delay of several months while it redesigns and tests the part.
GE Aviation Chief Executive David Joyce said. “There is a (stationary) component in the front of the compressor which is wearing prematurely."
GE expects the first flight of 777X to take place this year, he added.
