A gas turbine engine comprising a fan 13 with a plurality of blade 42s, a fan track liner circumscribing the fan and a removable cutter 50 arranged towards the fan blades for trimming the radial length of one or more fan blades. To trim the fan blades the cutter is arranged towards the blades, and the fan blades are rotated so that they are trimmed by the cutter. The cutter is then removed from the liner, after which a filler material may take its place. The fan track liner may comprise an abradable layer 28 proximal to the fan blades. The cutter may be inserted into the fan track liner. The cutter may trim the blades by machining or grinding. |
