SCD Welded Shut When 747 Converted To Full Pax?

Tue Mar 29, 2005 2:49 am

I don't know if this is the right forum for this question. I apologize if it isn't.

On the picture, on the back of the plane you can clearly see the SCD still in place, but the plane has been permanently converted to a full pax plane.
Is the SCD being welded shut or just closed and locked like it's always been when still in combi config ?

I would think they would just lock it. Modifying the aircraft permanently would be expensive and probably lower it's value at the same time - combis are relatively unusual and can be quite desirable. MEA leased out it's three 747-200 Combis (and it's own ops became 707-only) during the Lebanese civil war and paid it's entire wage bill with the income.

that and you cannot weld the particular aluminum alloy that the door and skin of the aircraft would be made of.

There's no point welding it shut. 742 convertibles also fly with a locked cargo door when they're in pax-mode, so why go through the trouble welding it if it can be just locked?

Usually, deactivated doors are bolted to the fuselage structure with brackets. They are easily reopened and reactivated by removing the brackets.
This plane is built to withstand anything... except a bad pilot.
