787 engine issues

Rolls-Royce and GE engines used in Boeing's 787 have caused some issues for the new aircraft. On Saturday, debris shot from the back of a GEnx engine during a ground test at the Charleston (S.C.) airport. The incident is being investigated. In an earlier incident, All Nippon Airways temporary grounded five 787s due to gearbox corrosion in the Rolls Royce Trent 1000 engines. Rolls-Royce is replacing the gearbox units.
