Believe it is usual to remove the fan blades for the ferry.....certainly the case for the -22 RB211s. Usually there is no transportation cases available down route so itthey end up strapped one each to pax seats.
Was invovled in a similar situation a few years back...... 3 eng ferry arriving back at base for immediate engine change. The ongoing enging was minus some parts , notably the IDG and Hyd pump so these were to be removed from the U/S engine....( has to be done before dropping as impossible to get access when engine is in the stand ). Ever tried to work on a big lump of metal that has been cold soaked at around minus 50 deg C for 8 hours plus ????? Perishing !!!
