In the 80`s we saw sometimes(mostly 747) with a fifth pod under the wing!
Was this only for carrying or also for tests?If this was only for carrying why they put it not into the cargo hold ?Why we don`t see this no longer?

It does still happen, there is a photo of a QF 747 carrying a 5th engine. However i could be wrong.

It was to ferry the engine to another location on a pax plane. Of course this had an effect on the perforamce but not that much i think.

I wouldn't say its a daily occurance, but it't not uncommon to see that. I've seen a UA DC-10 with that a while ago. They don't put it in the hold because most of the time, they have all the luggage and mail down there.

I haven't seen them left open like that though. Usually they have a dome over the intake to keep FOB out of it.

is that fifth pod actually used as a fifth engine in flight?And how do they hook it up onto the bottom of the wing?

I highly doubt that it is used, it probably spins around due to the force of the wind but that's about all.

They do not use the 5th engine as a functioning one in flight.

There is an assembly that attatches to the wing spar if im not mistaken.

Bolts and duct tape...Lots of duct tape.

The fifth engine is not used in flight. It is used to ferry an engine to another aircraft. The engines (widebody aircraft) will not fit in the lower deck cargo hold due to size. They will fit on the maindeck of Combi or Freighter.

Now many narrow body engines are transported via lower deck hold. KE in ATL would get Air Tran DC-9 engines from New Zealand after overhaul work.

I have seen 747 and DC-10 engines transported to SIN in the maindeck of a B747 freighter. Now a 777 will fit but has be loaded more to center of the aircraft due to size.

In the early 1970's when the original 747s ere having so much trouble with their engines, I remember a 747 stuck in Sydney awaiting a replacement engine. Aircraft witha spare engine in a 5th pod were dispatched from London, but the first one had to use the spare engine itself before it reached Sydney. Luckly things have improved since then. The spare engine is bolted to a hard point, which is built into the wing during manufacture, and many aircraft had them including the B707 and the VC-10 and I am sure there are many others. Things have changed since the days of a picture of a Locheed Constellation [Pan Am ]whose No 4 engine fell off in flight, but landed safely. The damage was considered too severe to be handled by an outstation so the remaining portion of the powerplant was removed back to the wing and faired in. The aircraft then flew on 3 engines from the east coast of the USA back to the west coast for repairs. Needless to say only the minimum crew were on board

The reason you don't see 5th pod as often is the prevelance of wide body frieghters flying around the world.

Also 5th pod was an option and not standard on the jumbo.

Many early jetliners had the capability to transport a spare engine when needed. This includes the DC-8, DC-10, L-1011, 707 and 747.
Here's a Gulf Air L-1011

Can't find a DC-10 pic, but the pod was mounted between engine #1 and the fuselage.
