Abstract
The blade of a fan of a gas turbine engine situated within an intake duct is removed using apparatus including a support structure supporting a cantilevered platform for an operator and a guide rail which is profiled to receive a blade root of the blade. The operator releases the blade and slides it from its recess in the fan disc into a complementary guide channel in the guide rail. The guide rail follows a path which constrains the blade to move in a direction, and at an orientation, which avoids interference with the intake duct.
