5 engines
This feature has been offered on the 747 for a long time, maybe from day one, but don't remember ever seeing one in use. Looks like they have a shroud mounted behind the spinner to block flow into the core of the spare engine. The text on the link alludes to this--don't recall that feature being part of the kit either. |

Quoted:
Very common in the B747 fleet. We had numbers for takeoff, cruise and landing on the -200 fleet and I know they have them for the -400/-8. Cheapest way to ship spare engines around the system, really no big deal. This. It is a rarity now days. But it is a great way to ship spare engine to a remote location or back to the shop. The old JT9-7a engines has some teething issues back in the early days and trying to ship a large engine was kind of a bitch back then. |

The carrying of a 5th engine for transport was removed from the design of the -8 The fan blades are removed and a plug is entered so no air goes through the core. Will |

The structure inside the wing for the mount for the 5th engine was removed from the -8 as many operators did not use the option. The other minor models (100,200,400) that do have it when the 5th engine is installed the fan blades are removed and a plug is installed so no air goes through the core. Will |
