1. A method for removing a front seal plate from an aircraft engine, comprising at least the following steps:
a) separating a part engine unit from an aircraft engine,
wherein the aircraft engine comprises:
an N1 shaft;an N2 shaft,wherein the N1 shaft is surrounded coaxially by the N2 shaft;a front seal plate nut;a front seal plate; andan engine shroud,wherein the N2 shaft is mounted in the engine shroud via a bearing unit,wherein the part engine unit comprises:
a core engine; anda low-pressure turbine of the aircraft engine,wherein the N1 shaft, the N2 shaft, the front seal plate nut, and the front seal plate remain in the part engine unit while the part engine unit is separated from the aircraft engine; b) removing the front seal plate nut from the part engine unit,
wherein the N1 shaft and the N2 shaft remain in the part engine unit while the front seal plate nut is removed; and c) removing the front seal plate from the part engine unit,
wherein the N1 shaft and the N2 shaft remain in the part engine unit while the front seal plate is removed.
