The 747-8 And A Fifth Pod.

Mon Jun 25, 2012 1:44 am

Just wondering if the -8 can carry an engine in a fifth pod if necessary ?

The 5th pod was an option that only 3 original operators chose, largely due to the lack of ability to ship a motor the size required for a 47 at the time.
There are turbines out there now considerably larger now not requiring an additional pod and shipped by freight aircraft which were not available at the time the 47 was new.
I suspect the option has fallen off into the round file.

I suspect not; they never tested a 5th pod and, given the new wing and significant size difference for the GEnX-2B over prior 747 engines, I don't think you'd be able to have certified it without flight testing.

Qantas ordered the 5th pod option on their -400's...they may have been the only operator to order it on the -400.

SA also had the option on its 744s. There are (were?) a couple of photos in the database of SA 744 with the pod fitted.

Since the question involved the 747-8 it's not clear what 747 model you are referring to. If you are referring to all 747s, there are A.net photos of 747s (all models, -100/200/300/400) of at least 12 original operators with the 5th pod installed.

If I am not wrong AI had the option too. Incidently AI 182 was carrying a 5th engine back to BOM when it went down.

I don't think having this option is quite the deal it was with the growth of large freighters and regional repair shops.

I will say that passengers tend to like symetric aircraft and seeing 3 engines on one side does tend to freak those that notice out a bit.

All 747-100/200/300 series had the option (attachment point installed) to carry a fifth pod.
If an operator wanted to use this option, Boeing provided the amended OM (after paying the required fee).

AFAIK only the PW JT9D series and the RR RB211-524 series were certified for fifth pod operation at the 747 classic aircraft.
No GE engines (-50E/E1/E2 and -80C2B series) were certified for fifth pod operation. Both GE engine types were designed to be split for (lower deck) transportation and all early 747/CF6 operators (KL, AF, LH, etc) had 74M and/or 74F in their fleets, able to transport a spare engine (no splitting required) at the main cargo deck.

I have no knowledge about fifth pod operation at the 747SP.

The 747-400 series were also sometimes used for fifth pod operation. Known users are QF and SA (both RB211 series). But at that time (end of the eighties of the last century) almost all spare engines are already shipped with 74M, 74F or other wide body freighter aircraft.

The 747-8 series has not been certified for 5th pod operation. Also AFAIK no attachment point and re-enforced wing structure , inboard of engine #2, has been included in the new wing built up. ( for weight saving reasons ?).

Operating a twin over the ocean, you're always one engine failure from a total emergency.

For a video of recent QF "fifth pod" operation see the following video from 24 November 2011.
