Didn’t dig too deep into that, maybe you folks know:
There never seems to be a difference in empty weight between a pax version and a cargo version of the same aircraft. How come? I thought the empty weight of a pax airliner includes some kind of basic cabin layout? Of course optional fancy IFE and bed-bunks for business and first is nothing to include in “empty”.
But I assume a freighter should be lighter empty, not much over green PLUS the cargo handling system. But that can’t add up to the weight of a cabin. Sound and other insultation might go out, the big version of the climate control system, toiletts, kitchen, safety stuff, &c. There has to be a difference!
Anybody got any idea, or perhaps hard data on the real empty weight of freighters vs pax versions?
I read Cathay threw out everything possible from their 747F (incl ext paint), but they don’t say how much it was, and what the base was.

On the 2006 ACAP of the A380 the OEW of the Pax-version is given with ~270t, and the freighter is given with 250t. I would guess that for converted freighters the weight benefit is smaller, as some structural features cannot be removed (doors, for example).
Anyways, as I happen to know the actual OEW of the in service A380, I know there is quite a gap between published values and actual values. I guess for new-built the A380-values (see Wikipedia) may be transferred on other aircraft.
Just the actual given values for OEW are all rubbish.
Officially, the cabin is included in the OEW.
In case of the A380, you’ll find half a dozen of different OEWs.
