Turbofan engine

An apparatus (10) for a gas turbine engine (12) comprises a spool lock (14) for locking a compressor spool (30) and a lift (16) for removing a rotor (20) from the compressor spool (30). The spool lock (14) comprises an outer ring (26) configured for attachment to a compressor case (48) of the gas turbine engine (12), an inner ring (27) configured to support a compressor spool (30) within the compressor case (48), and a web (28) extending between the outer ring (26) and the inner ring (27). The lift (16) comprises a beam (34) configured for attachment to a flange (22) of the gas turbine engine (12), a support strut (36) configured to support the beam (34) above the compressor spool (30), and a hoist (18) configured to support the rotor (20) for removal from the compressor spool (30).
